On Tuesday 9 October, Skype, the popular internet voice and video service, issued a security notice confirming malicious activity targeting its users.
Dorkbot is a type of malware that is currently spreading via Skype instant messages. Users may receive a message asking 'lol is this your new profile pic?', along with a link. Do not click this link.
If the link is clicked, the malware infects your computer. It may also cause your computer to become part of what is known as a 'botnet'. A botnet is a group of compromised (infected by malware) computers that are used by criminals to carry out attacks on other computer systems.
Dorkbot variants may also attempt to steal user name and password details for other services you use. Botnets are controlled remotely and can be instructed to perform further malicious acts via the internet.
Skype users should update their Skype software to the latest version in order to ensure the security features are up to date. Users should also ensure their anti-virus software is up to date.
