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.
Malicious QR codes were used to establish a separate device as a ‘linked device’ which would allow the attacker to receive and read Signal messages sent to and from the target
What exactly is the cooperation that Signal was doing beforehand? Signal claims to collect very little data so I’m not sure how exactly they help?

Except Signal should not have that data. They claim they do not log that information, so it should be impossible for them to do that.
Unless signal is lying, that’s not something they can do.
