Lastpass breached

June 16th, 2015 by admin in cracking, Password Info

Lastpass team discovered suspicious activity on their network 6/12. In all, the unknown attackers obtained hashed user passwords, cryptographic salts, password reminders, and e-mail addresses. Although they harden your authentication hash with a random salt and 100,000 rounds of server-side PBKDF2-SHA256, you should change your password and add some multifactor authentication to be on the safe side.

Despite the rigor of the LastPass hashing regimen, the job of cracking a single hash belonging to a specific, targeted individual would be considerably less difficult and potentially within the ability of determined attackers, especially if the underlying password is weak. Passwords are “hashed” by taking the plain text password and running it against a theoretically one-way mathematical algorithm that turns the user’s password into a string of gibberish numbers and letters that is supposed to be challenging to reverse. The weakness of this approach is that hashes by themselves are static, meaning that the password “123456,” for example, will always compute to the same password hash.

If you are using an easily guessed dictionary based password as described by Errata Security you should change your password. Although on a NVIDIA GTX Titan X, which is currently the fastest GPU for password cracking, an attacker would only be able to make fewer than 10,000 guesses per second for a single password hash using the password algorithm:
PBKDF2(HMAC-SHA256, sha256(PBKDF2(HMAC-SHA256, password, salt, rounds)), salt, 100000)

rounds = user_rounds || 5000 // the iteration count is user-defined. default is 5k
encryption_key = PBKDF2(HMAC-SHA256, password, salt, rounds) // this unlocks your vault
auth_key = sha256(encryption_key) // this is what is sent to the server for authentication
server_hash = PBKDF2(HMAC-SHA256, auth_key, salt, 100000) // what’s stored in the auth db

85,100 Forbidden Dropbox Passwords

June 8th, 2015 by admin in cracking

Jerod Brennen was messing around with opening the dropbox mobile app and stumbled across a javascript file that checked a user’s signup password. Inside was a file called pw.html, which had a line inside the javascript that had 85100 passwords that users were forbidden to use when signing up. It was part of an old project that Dropbox had integrated into their app called zxcvbn (You can test it live ::HERE::). Apparently WordPress also has the JavaScript library into their code too.

They had based most of the passwords on a study by Mark Burnett from 2005 and 2012 that compiled the 500 and 10000 most common passwords which we covered a few years back. The handy password cracking list is available on Jerod’s site for download ::HERE:: hacked

Adult Friend Finder, the no-strings sex solicitation service that’s familiar to anyone who’s ever visited a porn site, was apparently just the victim of an enormous data breach, exposing millions of people who clicked banner ads hoping to get laid.

The person behind the leak, who goes by ROR[RG], claims he hacked Adult Friend Finder because they owed a friend of his money:

ADULTFRIENDFINDER.COM > this is for owing my guy $247,938.28 BITCH!!!!!!!!!!!

You have been ROOTED ;D

Cuz Itz Pay yo DUEZ or we COMIN 4 U!!!!!!

shout outz to Hell for the bandwidth:

Word to the wise, don’t use your work email address for kinky sex sites. .gov accounts anyone?

UPDATE: now you can check if your email was in the dump

PixieWPS – router WPS passwords in seconds

May 4th, 2015 by admin in cracking, Wireless

Pixiewps is a tool used for offline brute forcing of WPS pins. It dramatically speeds up the WPS brute force attack time from what was taking up to 12 hours to a a few seconds by exploiting the low or non-existing entropy of some wireless access points. It’s based on the pixie dust attack, discovered by Dominique Bongard (slides and video). Notes on how to install it are in the video below, if you are using Kali Linux then just apt-get update && apt-get upgrade.

Statistics Will Crack Your Password

April 28th, 2015 by admin in Password Info

Security firm Praetorian analyzed 34 million passwords that were jacked from the LinkedIn, eHarmony and Rockyou breaches, and found that 50% of all the passwords followed 13 basic structures. Over 20 million passwords in the sample have a structure within the top 13 masks. This lack of entropy makes it possible to use statistical analysis to make cracking faster and more effective. Part of the problem is with the websites themselves, as they just require one upper case letter or number. The result is that many sites falsely mark passwords as “strong” that could be cracked in a matter of minutes.


NetSPI’s Top Cracked Passwords for 2014

March 2nd, 2015 by admin in cracking

NetSPI collected 90,977 domain hashes during their penetration tests this year. Of the collected hashes, 27,785 were duplicates, leaving 63,192 unique hashes. Of the total 90,977 hashes, we were able to crack 77,802 (85.52%). Out of those hashes they calculated the top 10 passwords used.

Here’s nine of the top passwords that we used for guessing during online brute-force attacks:

  • Password1 – 1,446
  • Spring2014 – 219
  • Spring14 – 135
  • Summer2014 – 474
  • Summer14 – 221
  • Fall2014 – 150
  • Autumn14 – 15*
  • Winter2014 – 87
  • Winter14 – 63

*Fall14 is too short for most complexity requirements

ATT U-Verse VAP2500 vulns

November 25th, 2014 by admin in Privilege Escalation, Wireless

ATT U-Verse service includes the VAP2500 video access point as part of the installation,. From their guide “The VAP2500 enables you to transmit multiple standard- and high-definition video streams throughout your home wirelessly. You can enjoy a full range of video services and applications without having to run wires, lay cables, or drill holes. The U-verse Wireless Access Point operates only with authorized U-verse Wireless
Apparently it’s full of holes too:

1. Readable plain-text file, admin.conf, which holds the username and md5 encrypted passwords
(defaults are: ATTadmin : 1b12957d189cde9cda68e1587c6cfbdd MD5 : 2500!VaP
super : 71a5ea180dcd392aabe93f11237ba8a9 MD5 : M0torola!

2. They use the md5 hash of the username as a cookie for authentication

3. gui suppports command injection

GPU Cracking PDFs in 4 hours

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)

More info: hashcat forums
