UNN: Signal stopped responding to requests from Ukraine. How secure is Signal and what information did Signal give to Ukraine?

Signal is an encrypted messenger service, like What’s up or Telegram.

It is well known that What’s up is not secure as it can be breached by the CIA and most probably by other services. What’s up usually cooperates with law enforcement of many countries.

After the arrest of Telegram’s owner and founder Pavel Durov in Paris, it seems that Telegram now also cooperates with French and Western law enforcement. Telegram being considered as Russian, it was not a choice for Western users who are afraid of Russian surveillance.

Signal had a reputation of being secure, even though many rumors exist that it has been successfully hacked, by Russians and Ukrainians. Signal is a US product, so it cooperates with the US and other Western law enforcement. Signal, therefore, has not much acceptance in Russia and was revently banned for security reasons.

The article hereunder seems to suggest that Signal was cooperating rather intensively with Ukraine, officially with Ukraine’s law enforcement. Why that? Was it not rather an intelligence gathering on Signal users who are Russian or associated with Russia, or essentially in conflict with Ukrainian interests. It could be understood that following the earlier practice and under the Biden Administration’s guidance, Signal was involved in intelligence sharing with Ukraine.

This intelligence sharing may have halted around early March. There is a good chance that Ukraine still had some access to Signal’s intelligence sharing till 15 March. It may have been that certain high ranking officers of the Trump Administration we’re on the Ukrainian observation list shared with Signal. It is a fact that Moxie Marlinspike, Signal’s long-haired hippie founder turned billionaire, is publicly supporting Ukraine and also is ridiculing the Trump Administration. Pavel Durov stated once that, as Signal was founded by one of What’s up shareholders (Marlinspike), it cannot be a safe platform and is therefore connected to the US Government. Durov did not even think that Signal would be sharing intelligence with Ukraine – or eventually open its doors to Ukraine to get into the inner circles of the Trump Administration.

So, the question must be: was it an accident, or was the invitation to a rogue journalist (Atlantic’ editor in chief Goldberg) sent by hacking the phone/Signal App of Defense Secretary Hegseth or others.

Remind: to include a new chat member on Signal a specific operation and handling of the App is necessary. As well, the new contact needs to accept the invitation to enter the group chat. It may be the rogue journalist’s intentional fault, or it could even be a criminal act, that he secretly accepted to participate in a chat between the highest ranking US government officers, a chat to which he knows that he would never be invited and that the invitation could only be issued by mistake or by a hack … as he is an anti-Trump activist and a Trump hater. Depending on the legal framework, there is a possibility of unlawful intrusion into a private communication channel, probably also if invited by accident, but certainly if intruded by a hack.
