The encrypted messaging app Signal has stopped responding to requests from Ukrainian law enforcement regarding Russian cyberthreats, a Ukrainian official claimed, warning that the shift is aiding Moscow’s intelligence efforts.
Russia was caught running a bunch of side channel and phishing attacks using malicious QR codes. Presumably signal could help track these patterns in terms of time and place, to help isolate where espionage activity was occuring.
