Brief Description | |
Twins.F 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:
passwords saved by certain Windows services. It sends the gathered information to a remote user by any available means: email, FTP, etc. - In the local network:
it generates a large amount of network activity and consumes bandwidth.
It reduces the security level of the computer:
it changes system permissions, decreasing the security level. It uses stealth techniques to avoid being detected by the user: - It deletes the original file from which it was run once it is installed on the computer.
Twins.F 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.
- 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.
- Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
