The ResidentBat spyware was spotted this year after a reporter who was interrogated by the Belarusian KGB intelligence service started receiving malware alerts on his device, days after being questioned by authorities.

Last week, the US revealed the Russian government had used two state-backed hacktivist groups to carry out disruptive attacks against critical infrastructure worldwide.

The history and activities of the CyberArmyofRussia_Reborn (CARR) and NoName057(16) (NoName), were described in indictments and sanctions announced by the US Department of Justice and Treasury respectively, and in a joint advisory published by CISA. 

The US says that the CARR was "founded, funded and directed" by Russian military intelligence (the GRU) as an unattributable way of deterring anti-Russia rhetoric. The group was founded in early 2022 shortly after Russia's invasion of Ukraine, started out with DDoS attacks and over time has escalated to attacks on operational technology (OT) systems.

All five e-readers that were tested, and 24 of 35 smart TV models, used embedded browsers that were at least three years behind current versions.
