Anonymous hacktivists have threatened to target numerous UK government websites as the collective continues its campaign against those in power.
The group promised to mount a new series of attacks within the UK during an Anonymous internet radio message released on Wednesday.
The group subsequently posted what it claims are the results of systems scans taken of its intended victims on Pastebin.
The targets listed included the Home Office, Government Communications Headquarters (GCHQ), MI5, MI6, Number 10, the Supreme Court and the fast-food chain McDonald's.
That list included details of the apparent targets' operating systems and open ports that could be attacked.
Speaking to V3, a GCHQ spokesperson confirmed that the agency is aware of the threat, but said there was little risk to the organisation.
"It is worth pointing out that the GCHQ website is our public face and is not business critical. It has no impact on our operational capability. We have reasonable and proportionate Information Assurance precautions in place," they said.
At the time of publication, MI6, MI5 and McDonald's had not responded to V3's requests for comment on Anonymous' threats.
The threat follows on from a number of Anonymous led campaigns within the UK, including Team Poison's attack on an MI6 run anti-terrorism hotline.
The attack saw the group target the service with a denial of service, bringing it down by overloading it with hundreds of automated prank phone calls.
Following the attack, Trick, a teenager believed to be Team Poison's leader was arrested.
Prior to the attack Anonymous hacktivists had promised to target the UK Home Office as a part of a wider anti-extradition protest to support Chris Tappin, Richard O'Dwyer and Gary McKinnon.
