Social networking websites allow you to communicate and share information. But they can also be used to spread malware and to steal personal information.

Such sites have lax security, which enables criminals to access personal information that can be used to hack in to computers, bank accounts and other secure sites.

These sites can also be used for phishing exploits. For example, in 2009 Twitter users received messages from their online followers encouraging them to visit a website that attempted to steal their username and password. The same year, hackers accessed a British politician’s Facebook account and used it to send messages to contacts, directing them to a malicious webpage.

To prevent social networking threats, you should run web security solutions that check every link and webpage as it is clicked to see if it contains malware or suspicious activity. You should also ensure that your anti-virus or endpoint security is active.
