Security experts have warned of a new Skype spam operation that uses automated messages to place calls through the VoIP service in a bid to launch fake anti-virus attacks.
The message purports to be a 'system update' and warns the victim that their computer is lacking adequate security protection.
The attack has been documented by security firm Sophos, and V3 has already received a similar automated message warning of a possible security threat.
The message points to a URL for another web page that attempts to convince the victim to download and purchase security tools as well as hand over personal information.
"I'm not sure I would want to trust any product which uses Skype spam techniques to advertise itself, and presents itself in such an underhand manner," wrote Sophos senior technology consultant Graham Cluley in a blog post.
"Of course, if you don't want to receive unsolicited Skype calls the best thing to do is change your privacy settings so that only users listed in your contacts list are allowed to get in touch with you."
Rogue anti-virus attacks, also known as scareware, have long been a popular technique with scammers. The attacks often simulate a system alert message or security scan to trick people into believing that their system is infected.
