The Federal Bureau of Investigation (FBI), National Security Agency (NSA), US Cyber Command, and international partners released a joint Cybersecurity Advisory (CSA) to warn that Russia-linked threat actors are using compromised Ubiquiti EdgeRouters (EdgeRouters) to evade detection in cyber operations worldwide.
The US agencies and international partners (peers from Belgium, Brazil, France, Germany, Latvia, Lithuania, Norway, Poland, South Korea, and the United Kingdom) observed multiple Russia-linked threat actors (the Russian General Staff Main Intelligence Directorate (GRU), 85th Main Special Service Center (GTsSS), also known as APT28, Fancy Bear, and Forest Blizzard (Strontium)) using a botnet of compromised EdgeRouters devices, named Moobot, worldwide to harvest credentials, collect NTLMv2 digests, proxy network traffic, and host spear-phishing landing pages and custom tools.
