P2P Security Risks
P2P (peer-to-peer) file-sharing is a very popular and easy way for users to share music, movies, videos, and other files over the Internet. However, using P2P software is very risky, because it makes you very susceptible to infection, attack, exposure of personal or company information, and even copyright infringement issues
Installation Of Malware
If you use P2P applications, it is difficult, if not impossible, to verify that the sources of the shared files are safe. P2P applications are often used by attackers to transmit malware (malicious software). The files may contain spyware, viruses, Trojan horses, or worms. When you download the files, your computer can become infected. Currently, experts have estimated that over 70% of the programmes shared on P2P networks contain some sort of malware.
Exposure Of Sensitive Information
When using P2P applications, you may unknowingly give other users access to personal or sensitive information that is stored on your computer. People may be able to access your financial or medical data, personal documents, sensitive corporate information, or other private information. If your computer contains other people's or companies' information, you may even become legally liable if their information gets released in this way.
Vulnerability To Unwanted Attacks
Many P2P applications require you to open specific ports on your firewall to send and receive the shared files through. However, by opening those ports, you may give attackers access to the information on your computer or enable them to attack your computer by taking advantage of any security vulnerabilities that may exist.
Self-Induced Denial Of Service
Downloading files with these applications causes a significant amount of traffic over your Internet connection; it also relies on certain processes to happen on your computer. This activity may adversely limit or even block your access to the Internet while you are running these types of programmes.
Prosecution Due To Copyright Infringement
Downloading or sharing copyrighted software, music or videos is illegal. If you download them, even unknowingly, you may be faced with fines or other legal actions.
This lists only a few of the risks that P2P programmes can open you up to. You should consider not using these types of programmes.
