“The extrapolation is that that is being provisioned to russian forces to be als to deploy captured devices on the battlefield and send back the communications to the Gru to the Gru to Be Exploit
Russia is believed to have fed the intercepted Signal communications back to a “data lake” to analyse the content of large number numbers of signal communications for Battlefield Intelligence.
Compromise likely to go undetected
The Attacks, which are based on exploiting Signal's device linking capability, are difficult to detect and when successful there is a high risk that compromised Signal Accounts Can Go UNONOTICED long time.
Google has identified another cluster of Russia-Backed AttackersKnown as UnC5792That has used modified versions of legitimate Signal Group Invite Pages which link the Victim's signal account to a device controlled by the hacking group, enabling the grop to read and access the Target Signal messages.
Other russia-linked threat actors have developed a signal “Phishing kit” designed to mimic components of the Kropyva Artillery guidance software used by the Ukrainian Military.
