How To Unlock Forgot Pattern Password In Android Phone

We've all been there. You accidentally enter the wrong password into your phone too many times, and suddenly, you're locked out of the device for good. Maybe your kid or a friend of yours took your phone and, as a joke or an accident, entered the wrong code one too many times. Maybe it's your secondary phone and it's been sitting in a drawer for a couple months and now you need it – but you forgot the code. With photos of our friends and family, our entire music collection, and our contacts library saved on our devices, one can't just be expected to hard reset the phone if something goes wrong with the passcode on the device.

Being locked out of our phones feels a lot like being locked out of our entire life. That said, you don't have to worry about trying to find a way out from phone purgatory. If you've accidentally triggered a permanent lockout of your phone, or you're not quite there yet but you know you've forgotten the password, you might feel the need to start panicking. Maybe you haven't forgotten the code to your phone, but you're looking for a smarter way to unlock the device when you're using it day-to-day. If you're curious about how phone unlocks work, whether trying to get into your locked device or just trying to make sure you don't accidentally lock yourself out, you've come to the right guide. With any luck, we'll be able to get you back into your phone without losing an ounce of data. And for those users who haven't lost their passcodes but are simply trying to use their phones in a smarter, more secure way, we have some tips for you too. This is how to unlock your Android phone.



Forgotten Passcodes

You've picked up your phone to check your text messages or your email, only to realize that something is wrong with your passcode. Despite knowing that you've set the password to be, let's say, your first child's birthday, nothing seems to be working. Your phone continues to tell you the password is wrong, but you've checked the spelling three times. Finally, your phone alerts you that you've been locked out of the device for the time being. What to do when you need your phone to pay for groceries, call an Uber, or check Instagram while waiting in line at the bank. If you've forgotten your passcode, you aren't completely out of luck just yet.

Try Variations on Your Passcode

Are you entirely sure you aren't misremembering your password? The first piece of advice we would give you is to ensure your passcode isn't being mixed up, or that you aren't forgetting a key piece of your passcode that happens to come at the end of the phrase. Plenty of us often forget about little tweaks to passwords we've added in order to ensure that our devices are as secure as possible. Here are some tips to making sure you're remembering every piece of your passcode:

  • Capital letters: If you're using a passcode phrase, you might've forgotten to add in any capital letters to your text. Make sure you remember to place the capital letters correctly as well; we've all forgotten the correct word or letter to capitalize in passcodes like this.
  • Numbers: Sometimes you forget about the number you added on your passcode a couple days ago. If your passphrase spells out "WaterInJuly382," you'll want to make sure you remember to enter the "382" part of the password. Don't be surprised if you accidentally forget to add the numbers onto your passcode. It happens to the best of us.
  • Special characters: Just like the capital letters, sometimes we add special characters into our passcodes to make them as complex as possible, only to forget the characters just hours later. Think back to decide whether you added an exclamation point, a dollar sign, or any other special character to your code in order to protect your data. It might make the difference between a lost passcode and saving your data.

Find My Mobile (Samsung Devices Only)

Are you using a Galaxy S9 or a Galaxy Note 8? You might be in luck: Samsung's own Find My Mobile tool features an additional feature not offered by Google's own Find My Device tool. Find My Mobile is similar to Find My Device or Find My Phone on iOS, but developed by Samsung specifically for their devices. For the most part, it does the same stuff you'd expect: Find My Mobile can locate your phone using GPS, make the device ring when you lose it in your couch cushions, and can even backup your data remotely using the web app offered by Samsung. More importantly, however, is the app's ability to unlock your device from your computer even if you've forgotten the passcode for the device.

There's a catch: if you haven't set up your Samsung account on your Galaxy S-device, you won't be able to do this. Like most of Samsung's tools, you need a Samsung account to log into the site and to unlock your device. Assuming you have set up your Samsung account—and haven't forgotten the passcode to that account—you should be able to unlock your device using the Find My Mobile web app here. All you need to do is sign in with your Samsung account, select the option to remotely unlock your device, and you'll be all set to go.

It's important to note that unlocking your device remotely does clear the biometric data off your device, so any fingerprints or iris scans you have saved on your device will have to be added back to your phone – small price to pay for saving your device's data in the long run.

As we mentioned, Google has a similar utility for all Android phones called "Find My Device," which only features the option to lock your device, not unlock it. If you've forgotten your passcode, all Find My Device will do is locate the device by GPS, re-lock the screen, and erase data; it won't be able to unlock the screen from the cloud.

Last Resort: Resetting Your Device

Unfortunately, thanks to the security enhancements added to Android 5.0 and above, most modern devices that aren't made by Samsung will have to be reset in order to bypass the password. Yes, this means you'll need to set your phone up again from scratch, re-downloading apps, music, and any other content you have saved on your mobile device. Being locked out of your device makes it difficult to back up any content on your phone, but if you already have some backup methods put in place, you can trigger them by plugging your phone. Both Google Drive backups (Pixel only) and Google Photos backups are often triggered by plugging your phone into a charger, so making sure your device is plugged in is ideal for guaranteeing that your software is saved. We recommend waiting until morning to reset your device if you're locked out; plenty of these backups happen overnight, including most SMS backups if you have an SMS backup app installed and running on your device.

Because you can't access the settings menu to factory reset your phone, you'll need to either use the hardware buttons on your phone to trigger a reset or use Google's Find My Device page in a web browser to reset the phone. Here's how to do each step:

If you're using Google's Find My Device page, load the URL here, sign into your Gmail account, and make sure your phone is selected. On the right side of the display, you'll see a Google Maps layout with a display showing the current location of your phone. On the left side of the display, you'll see a tab with three options: Play Sound, Lock, and Erase. Hit the Erase option to automatically trigger a device reset. Remember that your phone has to be powered on and connected to the internet in order to use this method.

Now, if you don't have access to the phone and can't use Find My Device to restore the phone over the web, you'll need to rely on the second method. To manually erase the device and reset the phone, you'll need to use the hardware buttons to load into your device's recovery system. This is accomplished a little differently on every phone, so your best option is to search for your phone model on Google with the keywords "boot into recovery." Some devices, like Samsung's lineup of phones, are fairly easy to boot into recovery with; you turn off the phone and press and hold a specific button combination to boot into recovery. Other phones, like Google's Pixel 2 XL, are much more finicky, requiring you to press and hold on one key and press and release another at the right time in order to boot into recovery. There are so many various methods for each Android phone, it's basically a requirement to search for the correct method for your phone to do this.

Once you've booted into recovery mode, use your device's volume up and volume down buttons to scroll through the list until you reach "Wipe Data/Factory Reset." Use the power button to select this option, then confirm your selection on the next display. Your phone will begin to reset; make sure the phone is charged enough to ensure it can last at least 30 minutes without dying. Once your phone has rebooted back to the menu screen, you can set up your device by logging back into the Google account you use for your phone. It is vitally important you use the same Google account you used on your phone prior to resetting. Android has a built-in security protocol known as Factory Reset Protection that requires a recently-reset phone to have the same Google account as previously used on the device in order to prevent a thief from immediately using the stolen phone. If you don't have the password for your Google account, you can reset it, but that means you won't be able to log into your phone for 24 hours after the reset.

Backup + Factory Reset

Probably the best combination of things to do does require you plan ahead, and set up a backup of your phone's data to the Google Cloud. This way, even if you have to reset the phone for whatever reason, a reasonably current set of your phone's data will be available, intact, and ready to get your phone back into action. I will walk you through how to set this up. You will need a Google account for this.

To set up backup, follow these steps.

  1. Go to Settings on your phone.
  2. Select System->Backup.
  3. Select Google backup.
  4. Select "Backup Now"

Your phone will now copy the critical data to your Google account.

Restoring from backup is simple. After you reset your phone and attach your Google account to the phone again, it will automatically restore your data from backup. Running a backup takes only a few minutes on a WiFi connection, or even less if you keep your phone regularly backed up – get into the habit of setting off a backup every night when you go to bed and you will always have a near-realtime backup of your phone.

(Want to backup more than just your phone? You can with one of these speedy 4-TB portable hard drives from Toshiba. You can back up all the computers in your household, and still have room for a thousand movies.)

Unlocking Your Phone with Speed

If you aren't having trouble getting into your phone, but you want to make sure your phone is secure while simultaneously unlocking your phone with some serious speed in order to make your day easier, we have some advice. There are plenty of options for unlocking your device, and they all help to make unlocking your phone easier and to prevent a situation where you forget the code for your phone.

Smart Lock

Smart Lock is one of our favorite tools on Android that is unavailable on other platforms. It makes it easy to make sure your phone is always secure, while simultaneously working to stay out of your way when you want access to your device. Basically, Smart Lock offers Android users several ways to unlock their phones when they're using it, while keeping it locked when it's not near them. To turn on smart lock, you'll need to open up your settings menu on your Android device and head into the Security submenu. Under "Device Security," you'll find an option for Smart Lock. Type in your passcode or password to enter Smart Lock, and you'll be greeted with (as of writing) five unique options for unlocking your phone. Let's break each of these down:

  • On-body detection: This setting allows you to unlock your device once before disabling the lock for as long as the phone is in your hand or on your person. Using your smartphone's array of sensors, the device tracks when your device is in use, so you can turn the display off but keep the phone unlocked while it's in your hand. When your phone realizes that it's been set down, your phone will automatically re-lock, requiring a password. This isn't the most secure method Smart Lock offers, but it is pretty cool.

  • Trusted places: Sure, it's one thing to keep your phone locked when you're out on the town, but what about when you're sitting in your apartment watching Netflix and you just want to be able to use your phone without constantly worrying about your password? Trusted places works to use the GPS in your phone to detect that you're in a secure location of your choosing, and automatically keeps your phone unlocked for you. As soon as you leave your location, your phone relocks, keeping things safe and secure for you and your device.

  • Trusted devices: This might be the best of the five Smart Lock options, because it's ideal for keeping your devices safe when you're nearby and keeping your phone locked when you've left. Do you own a smartwatch, a fitness tracker, a set of wireless headphones, or any other device that syncs over Bluetooth? Trusted devices might be the option for you, allowing you to keep your phone unlocked when your phone is paired with your gadgets. Smartwatches and fitness trackers are ideal for this, but it also helps you keep your phone unlocked when driving in your Bluetooth-equipped car, when running with Bluetooth headphones, or when paired with a set of Bluetooth speakers.

  • Trusted face: Plenty of phones have had a face unlock feature, though none of them are quite as secure as the FaceID method on the iPhone X. Still, if you want, you can enable Trusted Face on your device in order to allow your camera to automatically unlock your phone when it recognizes you. However, Trusted Faces is much more easily fooled than the above methods, especially since a photo of you—or even a lookalike—could unlock your phone without having to use any security. Use this one with caution.

  • Voice Match: Voice Match is a bit different than the other options on this list, because largely speaking, it's used to activate Google Assistant more than unlock your device. Here's the deal: turning on Voice Match allows you to access your Google Assistant every time you say "OK Google," even while the screen is off. Once you've enabled that ption, you have a second choice: "Unlock with Voice Match," which allows you to automatically unlock your phone when the sound of your voice saying "OK Google" matches the saved voice model on your device.

You can enable just one or all five of these, so don't worry if you like the idea of Trusted Devices but don't want to use On-Body Detection. If Smart Lock makes you feel like you can't properly keep your smartphone secured while enabling these settings, you don't need to worry. Every Android smartphone with Smart Lock enabled has the ability to lock the device manually, requiring a passcode or fingerprint in order to use the device properly. At the bottom of your lock screen is a small lock icon that allows you the choice of manually locking your phone. How you use it is actually a little different depending on your device; for example, Samsung devices have you press the icon to lock the app, but the Pixel phones have you press and hold the icon.

Once you've done this, your phone will give you a small notification alerting you that your device has been manually locked, and that the device will stay locked until you're ready to manually unlock with either your fingerprint (if you've turned this on) or your passcode. Manually locking your phone disables all smart locks, so even if you turn on a trusted Bluetooth device, you'll have to either input your passcode or password, or use your fingerprint to unlock the device if you have biometric security enabled. We'll talk more about fingerprints in the section below, and more specifically, how you can keep your biometric data from being used against you on upcoming versions of Android.

Smart Lock is one of those features that seems like a no-brainer, since it's so damn easy to setup and use to your benefit. That said, using Smart Lock obviously raises security concerns overall, since it does keep your phone unlocked more often. You'll want to play around with Smart Lock to find the right combination of security and ease of use for you. Maybe that means unlocking the device when it's attached to your car's Bluetooth and when you're at home, but keeping it secured at work and leaving on-body detection disabled. Whatever the right combination is for you will likely be a personal decision, but with five different modes of Smart Lock available, you have plenty of options and combinations to choose from.

Fingerprints

Almost every Android device in 2018 has a fingerprint sensor equipped on the body of the device, allowing you to easily access your content without having to go through the hassle of entering your passcode every time you use your phone. Fingerprints aren't a perfect unlocking method, but they're fast, secure, and can be equipped with up to four fingerprint entries on most phones. If you aren't using the fingerprint sensor on your device, you should enable it if only to create a backup option. Even if you prefer to unlock your phone by using an unlock method like a PIN, pattern, or password, fingerprints are perfect if you're ever in danger of accidentally locking the device without knowing the proper password.

If you aren't one to use fingerprints to unlock your phone, one step you could take to ensure you never forget your passcode is set the fingerprint on your phone to unlock with a finger that isn't your thumb or index finger. For example, try using your pinky finger or your ring finger as a way to program a fingerprint without making it obvious. You'll always have the option to use your fingerprint as a backup if you forget your code, but otherwise, you'll be good to go when it comes to always having a way to unlock your phone. You could also try using the fingerprint of someone you intensely trust, like a partner or a child, if only to keep a backup that doesn't happen to be with you all the time. This is especially good if you're worried about being forced to unlock your phone by law enforcement, a pressing matter that is becoming more prevalent all the time.

Finally, if you're still worried about logging your fingerprints on your Android device due to security concerns, the upcoming release of Android P has a security feature built-in that allows you to quickly disable fingerprint scanning if you find yourself at risk of being forced to unlock your device. Called "lockdown" in the settings menu, the option allows you to immediately disable both fingerprints and Smart Lock, just by using the option that appears within the power menu on the lock screen. It only disables those features for one lock, but if you're in a place where you're worried your biometric or smartwatch lock features might be used against you, it's a great option to feel more secure.

Notes and Reminders

If you're the type of person who likes to use a complex password on their phone and balks at the idea of using any of the smart unlock features we highlighted above, you might want to consider using the lock screen text display as a way to leave yourself helpful notes and tips to make remembering your password that much easier. Every Android device on the market today has support for placing a message on the lock screen, and you can display some pretty long messages. While most people use this as a way to label their phone (the example in Android is "Joe's Android"), you can also use it to set what amounts to old password hints from Windows and other desktop operating systems.

So, for example, if you've set your password as the name and birthdate of your daughter (ie., "elizabeth1217"), you could set the reminder on your lock screen as "ebbirth", for "elizabeth1217." This can be done for any password, even if it's a random phrase. "Candy90erring60Blinders," for example, could be hinted at on your lock screen with "Reese's, Jewelry, Sunlight." You'll still have to work to remember the numbers and the correct words that match up with the other content, but it can go a long way in helping you to remember what your password is without giving it away. Again, this is totally optional, a way for users to remember their long passwords without having to deal with giving it away or writing it down.

Password Managers

This final tip is for those among us who have a reputation for forgetting passwords and passcodes. If you're always worried about losing your password to your phone and getting locked out, you might want to try using a password manager like Lastpass or 1Password, which allows you to save all your passwords in one place with a single unlock, typically requiring a fairly long phrase in order to gain access to your passcodes. We recommend Lastpass for password manager beginners, because it's free and works with all your devices out of the box. We recommend writing the passcode down somewhere safe and secure in your house, then saving your phone's password inside of Lastpass for safekeeping. It might seem like an odd choice, and certainly won't speed up the unlocking process if you do manage to forget your password, but it's always good to have a backup unlock method to keep your phone's data safe.

***

Losing access to your phone is a nightmare. It's where all of your personal data, from bank account information to photos of your family and friends, lives and is kept safe. Being locked out of your data can feel like the end of the world, but luckily, it doesn't have to be. Whether you're worried about locking yourself of your account, or you've recently updated your phone's password and want to make sure you don't lose it, there are plenty of options to ensure you don't lose access. And even if you have, you aren't completely out of luck, thanks to the various options that exist for getting back into your account.

If you're looking for a way to unlock your phone faster, there's all sorts of opportunities to make sure your Android device is ready for you to login without having to enter your password every time. Biometric security has become fairly commonplace in the mobile arena, and likewise, Smart Lock on Android has made it easy to keep your device secure when it needs to be and unlocked when it doesn't. Overall, the security options on Android have become so plentiful that there's no reason not to keep some kind of security on your Android device. Just make sure you remember the password before you save the account information.

OVER $60 MILLION WORTH OF BITCOINS HACKED FROM NICEHASH EXCHANGE

Over $60 Million Worth of Bitcoins Hacked from NiceHash Exchange. Bitcoin mining platform and exchange NiceHash has been hacked, leaving investors short of close to $68 million in BTC.
As the price of Bitcoin continues to rocket, surging past the $14,500 mark at the time of writing, cyberattackers have once again begun hunting for a fresh target to cash in on in this lucrative industry.
Banks and financial institutions have long cautioned that the volatility of Bitcoin and other cryptocurrency makes it a risky investment, but for successful attackers, the industry potentially provides a quick method to get rich — much to the frustration of investors.
Unfortunately, it seems that one such criminal has gone down this path, compromising NiceHash servers and clearing the company out.
In a press release posted on Reddit, on Wednesday, NiceHash said that all operations will stop for the next 24 hours after their "payment system was compromised and the contents of the NiceHash Bitcoin wallet have been stolen."
NiceHash said it was working to "verify" the precise amount of BTC stolen, but according to a wallet which allegedly belongs to the attacker — traceable through the blockchain — 4,736.42 BTC was stolen, which at current pricing equates to $67,867,781.
"Clearly, this is a matter of deep concern and we are working hard to rectify the matter in the coming days," NiceHash says. "In addition to undertaking our own investigation, the incident has been reported to the relevant authorities and law enforcement and we are co-operating with them as a matter of urgency."
"We are fully committed to restoring the NiceHash service with the highest security measures at the earliest opportunity," the trading platform added.
The company has also asked users to change their online passwords as a precaution. NiceHash says the "full scope" of the incident is unknown.
"We are truly sorry for any inconvenience that this may have caused and are committing every resource towards solving this issue as soon as possible," the company added.
Inconvenience is an understatement — especially as so much was left in a single wallet — but the moment those coins shift, we may know more about the fate of the stolen investor funds.

CEH: Gathering Host And Network Information | Scanning

Scanning

It is important that the information-gathering stage be as complete as possible to identify the best location and targets to scan. After the completion of  footprinting and information gathering methodologies, scanning is performed.
During scanning, the hacker has vision to get information about network an hosts which are connected to that network that can help hackers to determine which type of exploit to use in hacking a system precisely. Information such as an IP addresses, operating system, services, and installed applications.

Scanning is the methodology used to detect the system that are alive and respond on the network or not. Ethical hackers use these type of scanning to identify the IP address of target system. Scanning is also used to determine the availability of the system whether it is connected to the network or not.

Types Of Scanning 

Network ScanningIdentifies IP addresses on a given network or subnet
Port ScanningDetermines open, close, filtered and unfiltered ports and services
Vulnerability ScannerDetect the vulnerability on the target system

Port Scanning ​

Port scanning is the process of identifying open and available TCP/IP ports on a system. Port-scanning tools enable a hacker to learn about the services available on a given system. Each service or application on a machine is associated with a well-known port number. Port Numbers are divided into three ranges:
  • Well-Known Ports: 0-1023
  • Registered Ports: 1024-49151
  • Dynamic Ports: 49152-6553

Network Scanning

Network scanning is performed for the detection of active hosts on a network either you wanna attack them or as a network administrator. Network-scanning tools attempt to identify all the live or responding hosts on the network and their corresponding IP addresses. Hosts are identified by their individual IP addresses.

Vulnerability Scanning

This methodology is used to detect vulnerabilities of computer systems on a network. A vulnerability scanner typically identifies the operating system and version number, including applications that are installed. After that the scanner will try to detect vulnerabilities and weakness in the operating system. During the later attack phase, a hacker can exploit those weaknesses in order to gain access to the system. Moreover, the vulnerability scanner can be detected as well, because the scanner must interact over the network with target machine.

The CEH Scanning Methodology

As a CEH, you should understand the methodology about scanning presented in the figure below. Because this is the actual need of hackers to perform further attacks after the information about network and hosts which are connected to the network. It detects the vulnerabilities in the system bu which hackers can be accessible to that system by exploitation of that vulnerabilities.

$$$ Bug Bounty $$$

What is Bug Bounty ?



A bug bounty program, also called a vulnerability rewards program (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs. Bug bounty programs are often initiated to supplement internal code audits and penetration tests as part of an organization's vulnerability management strategy.




Many software vendors and websites run bug bounty programs, paying out cash rewards to software security researchers and white hat hackers who report software vulnerabilities that have the potential to be exploited. Bug reports must document enough information for for the organization offering the bounty to be able to reproduce the vulnerability. Typically, payment amounts are commensurate with the size of the organization, the difficulty in hacking the system and how much impact on users a bug might have.


Mozilla paid out a $3,000 flat rate bounty for bugs that fit its criteria, while Facebook has given out as much as $20,000 for a single bug report. Google paid Chrome operating system bug reporters a combined $700,000 in 2012 and Microsoft paid UK researcher James Forshaw $100,000 for an attack vulnerability in Windows 8.1.  In 2016, Apple announced rewards that max out at $200,000 for a flaw in the iOS secure boot firmware components and up to $50,000 for execution of arbitrary code with kernel privileges or unauthorized iCloud access.


While the use of ethical hackers to find bugs can be very effective, such programs can also be controversial. To limit potential risk, some organizations are offering closed bug bounty programs that require an invitation. Apple, for example, has limited bug bounty participation to few dozen researchers.

Change Passwords Regularly - A Myth And A Lie, Don'T Be Fooled, Part 1


TL;DR: different passwords have different protection requirements, and different attackers using various attacks can only be prevented through different prevention methods. Password security is not simple. For real advise, checking the second post (in progress).

Are you sick of password advices like "change your password regularly" or "if your password is password change it to pa$$w0rd"? This post is for you!

The news sites are full of password advises nowadays due to recent breaches. When I read/watch these advise (especially on CNN), I am usually pissed off for a lot of reasons. Some advises are terrible (a good collection is here), some are good but without solutions, and others are better, but they don't explain the reasons. Following is my analysis of the problem. It works for me. It might not work for you. Comments are welcome!

Password history

Passwords have been used since ancient times.


Because it is simple. When I started using the Internet, I believe I had three passwords. Windows login, webmail, and IRC. Now I have ~250 accounts/passwords to different things, like to my smartphone, to my cable company (this password can be used to change the channels on the TV), to my online secure cloud storage, to full disk encryption to start my computer, to my nude pictures, to my WiFi router, to my cloud server hosting provider, etc etc etc. My money is protected with passwords, my communication is protected with passwords/encryption, my work is protected with passwords. It is pretty damn important. But yet people tend to choose lame passwords. Pretty lame ones. Because they don't think it can be significant. But what is not essential today will be relevant tomorrow. The service you used to download music (iTunes) with the lame password will one day protect all your Apple devices, where attackers can download your backup files, erase all your devices, etc. The seven-character and one capital rule is not enough anymore. This advice is like PDF is safe to open, Java is secure. Old, outdated, untrue.

Now, after this lengthy prologue, we will deep dive into the analysis of the problem, by checking what we want to protect, against whom (who is the attacker), and only after that, we can analyze the solutions. Travel with me, I promise it will be fun! ;)

What to protect?

There are different services online, and various services need different ways to protect. You don't use the same lock on your Trabant as you do on your BMW.

Internet banking, online money

For me, this is the most vital service to protect. Luckily, most of the internet banking services use two-factor authentication (2FA), but unfortunately, not all of them offer transaction authorization/verification with complete transactions. 2FA is not effective against malware, it just complicates the attack. Transaction authorization/verification is better, but not perfect (see Zitmo). If the access is not protected with 2FA, better choose the best password you have (long, real random, sophisticated, but we will get to this later). If it is protected with 2FA, it is still no reason not to use the best password ;) This is what I call the "very high-level password" class.


Credit card data

This system is pretty fucked up bad. Something has to be secret (your credit card number), but in the meantime that is the only thing to identify your credit card. It is like your username is your password. Pretty bad idea, huh? The problem is even worse with a lot of different transaction types, especially when the hotel asks you to fax both sides of your CC to them. Unfortunately, you can't change the password on your credit card, as there is no such thing, but Verified by VISA or 3-D Secure with 2FA might increase the chances your credit card won't get hacked. And on a side note, I have removed the CVV numbers from my credit/debit cards. I only read it once from the card when I received it, I don't need it anymore to be printed there.
And sometimes, you are your own worst enemy. Don't do stupid things like this:


Work related passwords (e.g. Windows domain)

This is very important, but because the attack methods are a bit different, I created this as a different category. Details later.

Email, social sites (Gmail/Facebook/Twitter), cloud storage, online shopping

This is what I call the "high level password" class.
Still, pretty important passwords. Some people don't understand "why would attackers put any energy to get his Facebook account?" It is simple. For money. They can use your account to spread spam all over your Facebook wall. They can write messages to all of your connections and tell them you are in trouble and send money via Western Union or Bitcoin.


They can use your account in Facebook votes. Your e-mail, cloud storage is again very important. 20 years ago you also had letters you didn't want to print and put in front of the nearest store, neither want you to do that with your private photo album. On a side note, it is best to use a cloud storage where even the cloud provider admin can't access your data. But in this case, with no password recovery option, better think about "alternative" password recovery mechanisms.

Other important stuff with personal data (e.g. your name, home address)

The "medium level password" class. This is a personal preference to have this class or not, but in the long run, I believe it is not a waste of energy to protect these accounts. These sites include your favorite pizza delivery service, your local PC store, etc.

Not important stuff

This is the category other. I usually use one-time disposable e-mail to these services. Used for the registration, get what I want, drop the email account. Because I don't want to spread my e-mail address all over the internet, whenever one of these sites get hacked. But still, I prefer to use different, random passwords on these sites, although this is the "low level password" class.

Attackers and attack methods

After categorizing the different passwords to be protected, let's look at the different attackers and attack methods. They can/will/or actively doing it now:

Attacking the clear text password 

This is the most effective way of getting the password. Bad news is that if there is no other factor of protection, the victim is definitely not on the winning side. The different attack methods are:

  • phishing sites/applications,


  • social engineering,
  • malware running on the computer (or in the browser), 
  • shoulder surfing (check out for smartphones, hidden cameras), 
  • sniffing clear-text passwords when the website is not protected with SSL,
  • SSL MiTM,
  • rogue website administrator/hacker logging clear text passwords,
  • password reuse - if the attacker can get your password in any way, and you reuse it somewhere else, that is a problem,
  • you told your password to someone and he/she will misuse it later,
  • hardware keyloggers,
  • etc.

The key thing here is that no matter how long your passwords are, no matter how complex it is, no matter how often do you change it (except when you do this every minute ... ), if it is stolen, you are screwed. 2FA might save you, or might not.

Attacking the encrypted password 

This is the usual "hack the webserver (via SQL injection), dump the passwords (with SQLMap), post hashes on pastebin, everybody starts the GPU farm to crack the hashes" scenario. This is basically the only scenario where the password policies makes sense. In this case the different level of passwords need different protection levels. In some cases, this attack turns out to be the same as the previous attack, when the passwords are not hashed, or are just encoded.

The current hash cracking speeds for hashes without any iterations (this is unfortunately very common) renders passwords like Q@tCB3nx (8 character, upper-lowercase, digit, special characters) useless, as those can be cracked in hours. Don't believe me? Let's do the math.

Let's say your password is truly random, and randomly choosen from the 26 upper, 26 lower, 10 digit, 33 special characters. (Once I tried special passwords with high ANSI characters inside. It is a terrible idea. Believe me.). There are 6 634 204 312 890 620 different, 8 character passwords from these characters. Assuming a 2 years-old password cracking rig, and MD5 hash cracking with 180 G/s speed, it takes a worst case 10 hours (average 5) to crack the password, including upgrading your bash to the latest, but still vulnerable bash version. Had the password been 10 characters long, it would take 10 years to crack with today hardware. But if the password is not truly random, it can be cracked a lot sooner.

A lot of common hashing algorithms don't use protections against offline brute-force attacks. This includes LM (old Windows hashes), NTLM (modern Windows hashes), MD-5, SHA1-2-512. These hashing algorithms were not developed for password hashing. They don't have salting, iterations, etc. out of the box. In the case of LM, the problem is even worse, as it converts the lowercase characters to uppercase ones, thus radically decreasing the key space. Out of the box, these hashes are made for fast calculation, thus support fast brute-force.


Another attack is when the protected thing is not an online service, but rather an encrypted file or crypto-currency wallet.

Attacking the authentication system online

This is what happened in the recent iCloud hack (besides phishing). Attackers were attacking the authentication system, by either brute-forcing the password, or bypassing the password security by answering the security question. Good passwords can not be brute-forced, as it takes ages. Good security answers have nothing to do with the question in first place. A good security answer is as hard to guess as the password itself. If password recovery requires manual phone calls, I know, it is a bit awkward to say that your first dog name was Xjg.2m`4cJw:V2= , but on the other hand, no one will guess that!


Attacking single sign on

This type of attack is a bit different, as I was not able to put the "pass the hash" attacks anywhere. Pass the hash attack is usually found in Windows domain environments, but others might be affected as well. The key thing is single sign on. If you can login to one system (e.g. your workstation), and access many different network resources (file share, printer, web proxy, e-mail, etc.) without providing any password, then something (a secret) has to be in the memory which can be used to to authenticate to the services. If an attacker can access this secret, he will be able to access all these services. The key thing is (again) it does not matter, how complex your passwords are, how long it is, how often do you change, as someone can easily misuse that secret.

 

Attacking 2FA

As already stated, 2 factor authentication raises the efforts from an attacker point of view, but does not provide 100% protection. 
  • one time tokens (SecurID, Yubikey) can be relayed in a man-in-the-middle attack
  • smartcard authentication can be relayed with the help of a malware to the attacker machine - or simply circumvented in the browser malware, 
  • text based (SMS) messages can be stolen by malware on the smartphone or rerouted via SS7, 
  • bio-metric protection is constantly bypassed,
  • SSH keys are constantly stolen,
  • but U2F keys are pretty good actually, even though BGP/DNS hijack or similar MiTM can still circumvent that protection,
  • etc. 


Others

Beware that there are tons of other attack methods to access your online account (like XSS/CSRF), but all of these have to be handled on the webserver side. The best you can do is to choose a website where the Bug Bounty program is running 24/7. Otherwise, the website may be full of low hanging, easy-to-hack bugs.

Now that we have covered what we want to protect against what, in the next blog post, you will see how to do that. Stay tuned. I will also explain the title of this blog post.Read more
