P2PShared.E 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.

• In the local network: it generates a large amount of network activity and consumes bandwidth.

It reduces the security level of the computer: it notifies the attacker that the computer has been compromised and is ready to be used maliciously; it changes system permissions, decreasing the security level.

It uses several methods in order to avoid detection by antivirus companies:

• It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.
• It terminates its own execution if it detects that a memory dump program is running, such as Procdump.

P2PShared.E 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.
