Users Ashley Madison Had Often Name As Password


Users of the Ashley Madison website often used their username and password, so researchers have discovered. The group of researchers called Cynosure Prime showed last week that by some programming errors crack the password hashes of Ashley Madison are simple. At the hack of the cheaters website approximately 36 million password hashes were stolen.

Hashes to ensure that the user passwords are not immediately visible to an attacker in case the website is hacked. Ashley Madison used before a strong hashing algorithm, but by various programming errors hashes prove yet easy to crack. The researchers have cracked 11.7 million password hashes.

It shows that mainly weak and insecure passwords were used. So there were three million passwords of six characters and there were slightly less than 3 million, which consisted of eight males kara. The shortest password was cracked one character long. Nearly 10 million passwords only consisted of small letters or lowercase letters and numbers.

User Name

The researchers were also curious how many users are using their username and password. A total of 630 000 passwords were found that matched the user name. The investigators noted that the actual number is higher as possible, since there are obvious only obvious mutations were used. If there was more combinations of uppercase and lowercase letters sought was the true number is likely higher. The researchers argue that these passwords could be cracked too easily without programming errors found.

Striking Passwords

Instead of publishing a list of the Top 10 most common passwords, the researchers decided to create a collection of distinctive passwords. It is about passwords as allthegoodpasswordshavegone ',' youwillneverfindout ',' everynameitriedwastaken ',' goodguydoingthewrongthing ',' thisisagoodpassword 'and' correct horse battery staple ", known from the xkcd strip.

Researchers Crack 11 Million Passwords Ashley Madison


Researchers have managed to crack more than 11 million passwords of Ashley Madison users, as they have announced today. The group of researchers called himself the cynosure Prime and examined the data that was stolen by the cheaters website. Attackers managed to steal gigabytes of data at Ashley Madison, including hashed passwords of users.

It involves a total of 36 million password hashes. Ashley Madison had the passwords are not stored in plain text, but in hashed form. This makes them not directly readable, but they can be cracked. For hashing the password had Ashley Madison the bcrypt algorithm used, and there was also a "salt-made 'use. This makes it much more difficult to crack password hashes. In a weaker algorithm, such as MD5, it is possible to try millions of password combinations per second. In the case of the gesalte bcrypt hashes came another researcher with his computer not go beyond 156 hashes per second. This investigator knew in five days 4000 passwords to crack.

It was therefore argued that the cracking of all Ashley Madison password hashes would last for centuries. That now seems not to be so. The researchers from Cynosure Prime investigated namely the second amount of data that was recently put online. In it they found information that helps them with the bcrypt hashed passwords could crack much faster. "Instead of cracking the slow bcrypt hashes, which is currently a hot topic, we decided to choose a more efficient approach and attack the MD5 tokens," the researchers said in their explanation.

The cheaters website appears to have used for reasons still unknown MD5 tokens. These tokens can be cracked much simpler than the bcrypt hashes. The information from the cracked tokens could then be used to crack the hashes bcrypt, she discovered. Since the researchers two weeks ago with their research, they began now more than 11.2 million bcrypt hashes cracked. In total there were in the stolen data over 15 million tokens.

Director Ashley Madison Departs After Massive Hack


The director of Ashley Madison has resigned after attackers managed to steal confidential data of 32 million users, including names, addresses, email addresses and hashed passwords. Also all kinds of confidential business information were stolen, including e-mails.

It was gigabytes of data that have been published in part last week. In a statement enables Avid Life Media, the company behind Ashley Madison CEO Noel Biderman which has resigned and no longer works for the company. Until a new director was appointed the existing management team will lead the company. The company also states that it is still working on the settlement of the attack and actively with international investigative agencies work together to identify the perpetrators.

Researcher Cracks 4000 Passwords Ashley Madison


A researcher has managed to crack 4000 passwords of users of Ashley Madison, which demonstrates how important it is to choose a strong password. Attackers managed last month to steal a large amount of data from Ashley Madison, the site for cheaters.

The data were published last week in part. Among the stolen data there were also 36 million password hashes. Ashley Madison had the passwords are not stored in plain text, but in hashed form. This makes them not directly readable, but they can be cracked. Dean Pierce, Linux security engineer at chip giant Intel, password hashes ended with his special "squat machine" to crack.

Computer Pierce consists of four R9 290 ATI video cards. For hashing the password had Ashley Madison the bcrypt algorithm used, and there was also a "salt-made 'use. This makes it much more difficult to crack password hashes. In a weaker algorithm, such as MD5, it is possible to try millions of password combinations per second. In the case of the make bcrypt hashes came Pierce with his computer not go beyond 156 hashes per second.

The experiments also revealed the extent of the number of password hashes problematic, so he could load 6 million of the 36 million password hashes. For cracking the hashes he used the RockYou dictionary. RockYou is a company developing widgets for social media. In 2009 it was hacked, giving attackers more than 32 million managed to steal passwords. These passwords were stored in plain text, and finally appeared on the Internet. Since then the passwords of RockYou be used by many researchers as the default password cracking.

Crack Time

Pierce had his machine power for five days, during which he finally managed to crack 4000 passwords. That equates to 32.6 cracked passwords per hour. It also showed that there were 1191 unique passwords between. The most common password is "123456", which occurred 202 times. It also showed that 105 users had chosen the password "password". Pierce made ​​a Top 20 of the most common passwords. The list is very similar to other password lists that are regularly published.

According to the researcher, it is probably impossible to crack each bcrypt password, but will in the case of Ashley Madison eventually many passwords are outdated anyway. It is in this case especially for weak passwords which are found in many dictionaries, or simply through brute force to retrieve his. Thus, on the list of passwords of the short Pierce especially less than eight characters.
