The White Hat vs. Black Hat saga continues at Stamford Linux Super computer center.

LinuxToday internetnews.com reported that a super computer research facility at Stamford University had been compromised. Funny though, the reported attacks used to compromise the system used a high level of “sophistication”, this included guessing local user account passwords (god, secret, password, student, love, welcome, design) followed by executing publicly available exploits for Linux based and Solaris systems. After the escalation to root, the reported attackers ran dictionary attacks on password files by using a 10 to 20 year old tool called John the Ripper. Once more accounts had been compromised the attackers sniffed and broke a weak implementation of Kerberos authentication cracking even more user accounts. According to the article, the attackers finished there attack by installing publicly available root kits. The attackers were discovered when they modified user accounts so that students and research staff could no longer login.
