It spreads and affects other computers.
It sends the information it has captured to a remote user.
It generates a large amount of network traffic activity with the consequent consumption of bandwidth.
It carries out actions that decrease the security level of the computer.
It uses anti-monitoring techniques in order to prevent it being detected by antivirus companies.

P2PShared.A.worm 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.A.worm 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.
