Slammer Virus

The SQL slammer worm is a computer virus (technically, 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 10 minutes. Although titled "SQL slammer worm", the program did not use the SQL language; it exploited two buffer overflow bugs in Microsoft's flagship SQL Server database product. Other names include W32.SQLExp.Worm, DDOS.SQLP1434.A, the Sapphire Worm, SQL_HEL, and W32/SQLSlammer.read more
