RC4 has been exploited in high-profile attacks across enterprise Windows networks Kerberoasting exploits weaknesses in Active Directory, allowing attackers to perform offline password cracking ...

First some introduction. There is a course at my university called Cryptography and Network security that runs bi-annualy and usually contains a challenge to crack some cipher using distributed ...

A recently published paper described an attack that can break the RC4 cipher and decrypt user cookies. How does the attack work, and how can enterprises avoid being vulnerable to an attack? Is RC4 ...

There has been speculation that the well known RC4 cypher can be broken by state agencies. Now we have a new result which indicates that it is possible to crack in 75 hours, which make it a practical ...

Microsoft released optional security updates Tuesday for various versions of the .NET Framework that prevent the RC4 encryption algorithm from being used in TLS (Transport Layer Security) connections.

RC4 is a symmetric cryptosystem, invented in 1987 by MIT cryptographer Ronald Rivest, who went on to found RSA Security. The algorithm has several known flaws, but it is still widely used. RC4 is also ...
