Replication across networks by exploiting weakly restricted shares (common for Randex family of worms).
Contains characteristics of an identified security risk.

Technical Details:

Possible Security Risk

• Attention! The following threat categories were identified:

Threat Category	Description
	A network-aware worm that attempts to replicate across the existing network(s)
	A keylogger program that can capture all user keystrokes (including confidential details such username, password, credit card number, etc.)
	A malicious trojan horse or bot that may represent security risk for the compromised system and/or its network environment
