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 ...

Microsoft is officially moving to shut the door on RC4 - a legacy cryptographic cipher that has quietly persisted inside Windows authentication environments for decades - and forcing organizations to ...

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 ...

About time: Microsoft introduced support for the RC4 stream cipher in Windows 2000 as the default authentication algorithm for the Active Directory services. The system has been insecure for even ...
