Using any P2P (peer-to-peer) file sharing program is a security risk
which can make your system susceptible to a smörgåsbord of malware infections
, remote attacks, and exposure of personal information. Even the safest P2P file sharing programs that do not contain bundled spyware, still expose you to risks because of the very nature of the P2P file sharing process. By default, most P2P file sharing programs are configured to automatically launch at startup. They are also configured to allow other P2P users on the same network open access to a shared directory on your computer.
The reason for this is that file sharing relies on its members giving and gaining unfettered access to computers across the P2P network. However, this practice can make you vulnerable to data and identity theft. Even if you change those risky default settings to a safer configuration, the act of downloading files from an anonymous source greatly increases your exposure to infection
. This is because the files you are downloading may actually contain a disguised threat. Many malicious worms and trojans, such as the Storm Worm, target and spread across P2P files sharing networks because of their known vulnerabilities.
