| Description | This memory-resident worm propagates across networks by exploiting the LSASS vulnerability, which is a buffer overrun that allows remote code execution and enables a malicious user to gain full control of the affected system. This vulnerability is discussed in detail in the following Microsoft page:
Microsoft Security Bulletin MS04-011 It also propagates via network shares by dropping a copy of itself into default shared folders. It uses cached user names and passwords to gain access to the said shares. It may also use a specific list of user names and passwords, apart from those that it gathers. This worm opens a random port and operates as an Internet Relay Chat (IRC) bot that connects to an IRC server. It then joins an IRC channel, where it waits for several commands from a malicious user. It also steals the product ID of Windows and the CD keys of certain game applications. |
