SQL SERVER – SQL Slammer (Computer Worm)

Just a day ago, while talking with my outsourcing team one of the DBA asked me question.

Is there any virus associated with SQL Server?

I really find this question very interesting as I did not know if there are any viruses associated with SQL Server. I searched Google for this answer and I found link on wikipedia about SQL slammer, which is computer worm.

Following excerpt is taken from wikipedia : The SQL slammer worm is a computer worm that caused a denial of service on some Internet hosts and dramatically slowed down general Internet traffic, starting at 05:30 UTC on January 25, 2003. It spread rapidly, infecting most of its 75,000 victims within ten minutes. So named by Christopher J. Rouland, the CTO of ISS, Slammer was first brought to the attention of the public by Michael Bacarella – see Notes. Although titled “SQL slammer worm”, the program did not use the SQL language; it exploited a buffer overflow bug in Microsoft’s flagship SQL Server and Desktop Engine database products, for which a patch had been released six months earlier in MS02-039. Other names include W32.SQLExp.Worm, DDOS.SQLP1434.A, the Sapphire Worm, SQL_HEL, W32/SQLSlammer and Helkern.

  • And that was a tough day for many. I didn’t get a ton of work done that day (as most of the Internet was affected), but we remained largely unaffected. Basically this hit people hardest who didn’t have proper firewalls in place and had SQL ports exposed to the cloud…
