Hackivist group Anonymous has struck again at another high profile government target, this time in the UK.
At the weekend, the UK's Home Office website was downed by a distributed denial-of-service attack, apparently for several hours during Saturday evening. Access on Sunday morning was also flaky.
Anonymous tweeted: "Tango Down: http://www.homeoffice.gov.uk. Keep Firing!!!! Keep it down! Make them hear you!"
The online activist collective claimed in a later tweet that it had hit further government sites: "#Anonymous launched a cyberattack on http://www.number10.gov.uk, http://www.homeoffice.gov.uk & http://www.justice.gov.uk resulting in multiple TANGO DOWNS."
According to the BBC, Anonymous is planning such attacks every weekend. A further tweet stated: "Expect a DDoS (distributed denial-of-service) every Saturday on the UK Government sites."
The reason the Anon hive is so stirred up at the moment? Well, there appears to be a double motive - the first being to protest against the government allowing the extradition of UK citizens to face trial in the US.
Anonymous Operations tweeted: "#OpTrialAtHome is offered in protest of the potential extradition of Gary McKinnon, Christopher Harold Tappin & Richard O'Dwyer."
The other reason is the government's incoming online and phone call snooping legislation which extends GCHQ's surveillance powers.
Home Office officials noted that no data was touched during the attack, and the site is now back to normal. A Downing Street spokesman said the number 10 site hadn't been taken down, but did admit access was slow for a time.
