Signal no longer cooperating with Ukraine on Russian cyberthreats, official says therecord.media/signal-no…

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.

According to Serhii Demediuk, deputy secretary of Ukraine’s National Security and Defense Council, Signal remains one of the most exploited messaging apps for Russian espionage operations targeting Ukrainian military personnel and government officials.

“With its inaction, Signal is helping Russians gather information, target our soldiers and compromise government officials,” Demediuk said at the Kyiv International Cyber Resilience Forum on Tuesday.

Ukrainians have increasingly turned to Signal as an alternative to the Russia-founded messaging app Telegram, which has been widely believed to be exploited by Russian intelligence for data collection and influence operations, Demediuk said.
