A simple detail about password cracking tools from the wiki. In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A standard approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password. Password cracker is not hacking a password; this software only recovers your password. Got it? So don’t use against someone’s system or illegally.

The other purposes of password cracking tools might be to help a user recover a forgotten password of a system or any software. But in the world of hacking, hackers are using such a tools to break or crack the stolen password hashes of a database. Or using them to hack the wireless network and crack the passwords. So hope you completely understand the primary purpose of password cracking tools.

2. RainbowCrack

The RainbowCrack password cracking tools is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. It cracks hashes with rainbow tables. RainbowCrack uses time-memory tradeoff algorithm to crack hashes. It differs from brute force hash crackers.

A brute force hash cracker generates all possible plaintexts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked. Once a match is found, the plaintext is found. If all possible plaintexts are tested, and no match is found, the plaintext is not found. With this type of hash cracking, all intermediate computation results are discarded.

Features:

• Full time-memory tradeoff tool suites, including rainbow table generation, sort, conversion and lookup
• Support rainbow table of any hash algorithm
• Support rainbow table of any charset
• Support rainbow table in raw file format (.rt) and compact file format (.rtc)

Windows Operating System is weak against Local Password Cracking tricks. It is not only Windows, the other OS like Linux, Mac OS are also the same. But you can enable Syskey to protect Windows against local password cracking. By default, Windows doesn’t protect the system from bringing any changes to the SAM database. In order to protect Windows from local password cracking, Microsoft had set the Syskey within Windows NT 4.0 SP3. The Syskey utility can encrypt the hashed password information in a SAM database in the Windows operating system using a 128-bit RC4 encryption key.

Enable Syskey To Protect Windows

When you enable Syskey on Windows, the system asks you the Syskey password before displaying Windows log on-page. It seems like modern multi-factor authentication which Microsoft brought you a decade ago!

Syskey has the same configuration on all Windows. In order to enable syskey to protect windows, type “syskey” on Windows run and press enter. It will open syskey page and you must configure it.

On the Syskey (Securing the Windows Account Database) page click Update button. Before enabling Syskey, read the details and information on the pages.

Now on the Startup key select Password Startup and enter the password for syskey. The password must be strong enough to do not guess and crack easily. When done, just click OK.

When prompt that The account database Startup key was changed. Click OK and the syskey page will close. Don, the syskey enabled successfully.

After enabling Syskey on your Windows, it will ask you the password key when Windows has started up. This happens before displaying log on page of Windows. So till here, you protect the log on a page from bypassing Windows login page tricks which we talked about on the “Reset forgotten Windows Password” post.

To test the syskey, once restart your computer and see the start-up password prompt at startup.

Just enter the password of syskey that you enabled before. Try to remember the password or write somewhere else. If you forgot the password you are not able to login to your System. It’s possible to bypass syskey password, but is time-consuming and need some third-party tools to reset the password.

Any question? And feel free to ask us. We try to help you protect your system or suggest us a new tip for protecting Windows SAM Database.

Its that time of the year again. Google is laying down the plan for its annual hackathon, calling out hackers from all around the world to poke at its products and discover vulnerabilities. Any bugs discovered and they award cash prizes to the dexterous hackers that take the extra initiative in exploiting the loopholes in code that are present in Google’s apps.

Last year, Google dished out a staggering $2.1718 million in cash prizes to enterprising hackers. The choice of the number of the cash price was equivalent to ‘the mathematical constant e for the geeks at heart,’ according to Google.

This year, Google is again holding the Pwnium competition (named after the online lingo ‘pwn’, short for owning it and also rhyhming with Chromium, the complete name for Chrome). But there’s a big difference this time around. Now the competition wont be a single day affair, but a round-the-clock year long process.

The Pwnium competition is now a year long affair

The biggest benefit of this format change is that hackers can discover a bug and submit to Google online from wherever they are (although countries falling under the ambit of sanctions are disbarred from the contest, such as North Korea, Syria and Iran).

Another change that Google has made with the competition is that the prize amount isn’t going to be a static, fixed figure. According to Tim Willis, a member of Chrome’s security team and philanthropist, ‘it now goes the way to $ infinity million!’

Awards range from $500 to $50,000 and the overall pot is virtually unlimited now

In case people are shaking their heads at this figure, it means that awards will now be given from the minimum amount of $500 to $50,000. Google has made the cash pot virtually unlimited, at least for now that is. However Willis cautions that the new competition format of Google Pwnium is meant to be ‘experimental and discretionary.’

For hackers all around the world, the new changes mean that the barrier of entry is lower and now no one will sit on discovered bugs until its time for Google to hold its annual competition. This means more bugs will be squashed, making Google Chrome more secure than the other browsers in the market.
