Anatomy of a hack: How crackers ransack passwords like “qeadzcwrsfxv1331” In March, readers followed along as Nate Anderson, Ars deputy editor and a self-admitted newbie to password cracking, downloaded a list of more than 16,000 cryptographically hashed passcodes.

Within a few hours, he deciphered almost half of them. The moral of the story: if a reporter with zero training in the ancient art of password cracking can achieve such results, imagine what more seasoned attackers can do. Why passwords have never been weaker—and crackers have never been stronger. In late 2010, Sean Brooks received three e-mails over a span of 30 hours warning that his accounts on LinkedIn, Battle.net, and other popular websites were at risk.

He was tempted to dismiss them as hoaxes—until he noticed they included specifics that weren't typical of mass-produced phishing scams. The e-mails said that his login credentials for various Gawker websites had been exposed by hackers who rooted the sites' servers, then bragged about it online; if Brooks used the same e-mail and password for other accounts, they would be compromised too. The warnings Brooks and millions of other people received that December weren't fabrications. Advanced password recovery. Password analysis and cracking kit. PACK (Password Analysis and Cracking Toolkit) is a collection of utilities developed to aid in analysis of password lists in order to enhance password cracking through pattern detection of masks, rules, character-sets and other password characteristics.

The toolkit generates valid input files for Hashcat family of password crackers. NOTE: The toolkit itself is not able to crack passwords, but instead designed to make operation of password crackers more efficient. Before we can begin using the toolkit we must establish a selection criteria of password lists. Since we are looking to analyze the way people create their passwords, we must obtain as large of a sample of leaked passwords as possible. One such excellent list is based on RockYou.com compromise. The most basic analysis that you can perform is simply obtaining most common length, character-set and other characteristics of passwords in the provided list. . $ python statsgen.py rockyou.txt Below is the output from the above command: Combinator_attack [hashcat wiki] Description Each word of a dictionary is appended to each word in a dictionary.

Input If our dictionary contains the words: Password crackers go green by immersing their GPUs in mineral oil. Going where few password crackers have gone before, a team of security consultants has deployed a cracking-optimized computer that's completely submerged in mineral oil.

Members say the setup offers significant cost savings compared with the same machine that uses air to stay cool. The rig contains two AMD Radeon 6990 graphics cards, long considered a workhorse for password crackers. While the parallel processing in just one of these $800 cards can make as many as 9 billion password guesses each second (see PC3 in the graph at the bottom of this page), the performance comes at a price. GPUs run extremely hot, particularly when combined with other graphics cards, which drives up the cost of keeping them cool enough to run without burning out. The dedicated fans normally used to keep them cool also generate plenty of noise.

Locking the bad guys out with asymmetric encryption. Encryption, the transformation of data into a form that prevents anyone unauthorized from understanding that data, is a fundamental technology that enables online commerce, secure communication, and the protection of confidential information.

Encryption algorithms are the mathematical formulae for performing these transformations. You provide an encryption algorithm with a key and the data you want to protect (the plaintext), and it produces an encrypted output (the ciphertext). To read the output, you need to feed the key and the ciphertext into a decryption algorithm (sometimes these are identical to encryption algorithms; other times they are closely related but different). Encryption algorithms are designed so that performing the decryption process is unfeasibly hard without knowing the key. The algorithms can be categorized in many different ways, but perhaps the most fundamental is the distinction between symmetric and asymmetric encryption. Crummy passwords from Yahoo users.
