The Inside Story of SQL Slammer

By David LitchfieldOn Jan. 25, 2003, a new worm took the Internet by storm, infecting thousands of servers running Microsoft’s SQL Server software every minute. The worm, which became known as SQL Slammer, eventually became the fastest-spreading worm ever and helped change the way Microsoft approached security and reshaped the way many researchers handled advisories and exploit code. This is the inside story of SQL Slammer, told by the researcher who found the bug and wrote the exploit code that was later taken by Slammer’s authors and used as part of the worm.


‘All your IDS are belong to us,’ was the message on Monday, after researchers at networking security equipment vendor Stonesoft announced the discovery of evasion techniques that could be used by sophisticated attackers to bypass network based IDS and IPS. The disclosure raises questions about the effectiveness of a wide range of networking security products, but experts say those kind of questions are nothing new.

US CERT has issued an advisory following the release, late last week, of a critical patch from RealNetworks for seven vulnerabilities in its common RealPlayer software. CERT recommended users and administrators to review the advisory from Realnetworks to determine which RealPlayer products were affected and to patch any vulnerable systems. 

It’s been tried before, but NSS Labs founder Rick Moy says his company’s new Exploit Hub – a store front for exploit code – can work. In an interview with Threatpost.com, he explains why the current market for exploits doesn’t work for the good guys, and why zero day exploits don’t help anyone.
