November 9th, 2014 by admin in cracking

The hashcat guys have been working on code for oclHashcat guaranteed to crack PDFs within 4 hours. This is for PDF versions 1.1 – 1.3, which uses RC4-40,(v5 and 6 implement 128 bit RC4, v7 128 bit AES and X and later 256 bit AES).

  • Guaranteed to crack every password protected PDF of format v1.1 – v1.3 regardless of the password used
  • All existing documents at once as there’s no more salt involved after the key is computed
  • In less than 4 hours (single GPU)

Unlock systems infected by CryptoLocker.

August 6th, 2014 by admin in cracking, News


Researchers have struck back at the operators of the CryptoLocker ransom trojan that has held hundreds of thousands of hard drives hostage, the researchers managed to recover the private encryption keys that CryptoLocker uses to lock victims’ personal computer files until they pay a $300 ransom. Thanks to the security experts, an online portal has been created where victims can get the key for free.

To use the free service, victims must upload one of the files encrypted by CryptoLocker along with the e-mail address where they want the secret key delivered. They will then email you a master decryption key along with a download link to their recovery program that can be used together with the master decryption key to repair all encrypted files on your system.

Heart Bleed SSL Bug

April 8th, 2014 by admin in Browsers, cracking, News


A massive vulnerability has been found in OpenSSL, the open-source software package broadly used to encrypt Web communications. The flaw allows attackers to steal the information that is normally protected by SSL/TLS encryption, which is used to protect Web applications, e-mail communications, instant messaging (IM) and some virtual private networks (VPNs).
Essentially, that means a lot of Internet users are affected. And potentially, passwords, private communications and even credit card information could be available to hackers courtesy of this newly-discovered bug.
A few people have been checking major websites to check if they’re vulnerable

Offline NT Password & Registry Editor, finally got an update last month after a 4 yr hiatus. The new version of this awesome bootdisk includes support for Win8.1 and a working ‘promote user to admin’ feature among other fixes and driver updates.

2 new commandline functions are:
samusrgrp: a command line tool to add users to groups or remove users from groups. Users and groups must be local (cannot be domain / AD). It can also list the groups with their members in several forms, the output can be used in scripts of course. Listing groups will also list domain users that are members of the group (if any), but it will not be able to look up the name, so it will be listed as a SID only.

sampasswd: Password reset from command line (scriptable) Or list users in SAM file in a few different formats.
