Skype hit by DDoS attackPlayful hacker group CyberTeam claims that its recent DDoS attack on Skype was ‘all for fun’. Disgruntled Skype users across the globe were rather less amused by the outage, using social media to vent their spleen.

CyberTeam utilised a network of zombie computers – a botnet – to carry out the attack against Skype. So far its motives for doing so are unclear, and could they could range from causing reputational or monetary damage, to hiding other malicious activity on the network or establishing the group’s credentials as a serious player – or simply as a prank. CyberTeam also claims to have defaced multiple websites in Brazil and has threatened Steam, Valve’s digital gaming platform, with an impending attack.

Skype’s owners Microsoft acknowledged the loss of connectivity and has assured users that normal service has now been resumed. With thousands of corporate users relying on Skype for internal meetings, client calls and conference dial-ins, any interruption to the service can have serious knock-on effects rippling around the globe. DDoS attacks have been on the rise and despite this increase many organisations are slow to implement monitoring processes to keep an eye on DNS traffic – which can help identify DDoS attacks early.
