SMTP: MS-SQL Worm Email
This signature detects attempts to send an e-mail to ixltd@postone.com. This can indicate the presence of SQLsnake, a MSSQL worm. SQLsnake infects Microsoft SQL Servers that have SA (administrative) accounts without passwords. The worm sends a password list and other system information through email to ixltd@postone.com, then begins scanning for vulnerable hosts listening on TCP/1433.
