MSNWorm.HO is a worm that spreads by copying itself, without infecting other files.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
It sends the gathered information to a remote user by any available means: email, FTP, etc.
It reduces the security level of the computer:
it awaits remote-control orders received through
It uses stealth techniques to avoid being detected by the user:
- It uses techniques included in its code to hide itself while it is active.
MSNWorm.HO uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
- Peer-to-peer (P2P) file sharing programs: it makes copies of itself with enticing names in shared folders belonging to these programs. Other users of this type of networks then voluntarily download and run the infected files.
- Instant messaging: it sends links pointing to a copy of itself to all users included in the infected user's contacts list.
- Computer networks (mapped drives): it creates copies of itself in mapped drives.
