New RC4 Attack Dramatically Reduces Cookie Decryption Time

Two Belgian security researchers from the University of Leuven have driven new nails into the coffin of the RC4 encryption algorithm.

A published paper, expected to be delivered at the upcoming USENIX Security Symposium next month in Washington, D.C., describes new attacks against RC4 that allow an attacker to capture a victim’s cookie and decrypt it in a much shorter amount of time than was previously possible.
