Unprecedented Russia-Ukraine GPCyber™ Warfare Escalation | Pegasus Spyware Infiltrates UK PM Mobile & Downing Street Network – Staff Details Posted on Russian Social Media Site.

Pegasus spyware is suspected to have been used to infect the UK government’s 10 Downing Street network, researchers at Canadian internet security watchdog Citizen Lab have concluded.

A device connected to that network was infected using the spyware on 7 July 2020, according to a report on the research by the New Yorker.

The report added that the National Cyber Security Centre (NCSC) tested several phones at Downing Street including that of the prime minister – but was unable to locate the infected device.

It said the nature of any data taken was never determined.

John Scott-Railton, a senior researcher at the Citizen Lab, told the New Yorker: “When we found the Number 10 case, my jaw dropped.”
