Skype hit by 'worm' malware

  • Skype, the Internet message, phone and video chat service, is being used by hackers to spread a "worm" that infects Windows PCs.

    Users unknowingly download a file containing a Trojan horse malware file when they click on an instant message, which appears to be from one of their contacts, saying "lol is this your new profile pic?"

    This enables hackers to hijack infected PCs and recruit them into a "botnet army".

    Botnets are often used as a form of distributed denial of service (DDoS) attacks to run spyware or send out spam emails.

    According to online security firm Sophos, the worm is a variant of the "Dorkbot" worm. It has been previously been spread by social media sites such as Facebook and Twitter.

    In a statement, Skype said: "Skype takes the user experience very seriously, particularly when it comes to security. We are aware of this malicious activity and are working quickly to mitigate its impact. We strongly recommend upgrading to the newest Skype version and applying updated security features on your computer.”
