Websites belonging to online retail giant Amazon were inaccessible across the UK, Germany, France and Italy on Sunday, indicating at a possible DDoS attack from pro-Wikileaks hacktivists.
Multiple reports seem to place the blame for the attacks on "Internet gathering" Anonymous, but Twitter accounts connected with the outfit have denied involvement.
A post on the AnonOps account said: "WE REPEAT: We can not attack Amazon.com. To some journalists: check your sources well please. #anonops#payback #Wikileaks #leakspin"
The online retail giant was later followed by PayPal, Master Card and Visa in dropping WikiLeaks. The companies stopped processing donations meant for WikiLeaks through their payment channels. In response, Anonymous successfully brought down PayPal's API, the PayPal blog and the sites of both Mastercard and Visa with coordinated DDoS attacks.
