Christmas Day gamers ran into problems connecting their Xbox or Playstation to the internet thanks to a denial of service attack, and the hackers that have claimed credit are now naming a new target: online anonymity software Tor.
A group operating under the name “Lizard Squad” posted a series of tweets today about a planned zero-day attack, which target unnoticed weaknesses. In this case, that appears to be taking over the majority of Tor’s nodes: a series of points through which data sent over the Tor network travels. Tor protects users’ identities with these nodes, which obscure the origin of any data. Lizard Squad’s thought is if it controls enough of the nodes, information will no longer be anonymized.
As of this afternoon, Lizard Squad had about 3,000 nodes — nearly half of the 8,000 in existance, according to Gizmodo. But Redditors are questioning if the 3,000 nodes have enough weight to have any effect, as new nodes are vetted before they receive encrypted data.
Why is a hacker group interested in taking down software that has benefited countless other hackers? Lizard Squad posted a tweet documenting a possible motive:
This story is still developing, as Lizard Squad is working to gain more nodes. What has ended is the attack on Xbox and Playstation consoles. Lizard Squad thanked Kim Dotcom, who gave the group vouchers for his secure file hosting service Mega in exchange for ceasing the attack.
