Helkern Worm

Helkern Worm (sometimes referred to simply as Helkern) is a computer worm designed to specifically infect servers running on Microsoft SQL Server 2000. By exploiting a security breach in Microsoft SQL Server known as the Buffer Overrun, the Helkern Worm is capable of sending a request to a target computer that, when processed, automatically executes the Helkern Worm code. In this manner, an unauthorized user can run malicious code without approved consent.
