Share on X X.com Share on Facebook Facebook Email Email The Federal Bureau of Investigation (FBI) is warning the public, private sector, and international community of the threat posed to computer networks and critical infrastructure by cyber actors attributed to the Russian Federal Security Service's (FSB) Center 16. The FBI detected Russian FSB cyber actors exploiting Simple Network Management Protocol (SNMP) and end-of-life networking devices running an unpatched vulnerability (CVE-2018-0171) in Cisco Smart Install (SMI) to broadly target entities in the United States and globally. In the past year, the FBI detected the actors collecting configuration files for thousands of networking devices associated with US entities across critical infrastructure sectors. On some vulnerable devices, the actors modified configuration files to enable unauthorized access to those devices. The actors used the unauthorized access to conduct reconnaissance in the victim networks, which revealed their interest in protocols and applications commonly associated with industrial control systems. The FSB Center 16 unit conducting this activity is known to cybersecurity professionals by several names, including "Berserk Bear" and "Dragonfly," which refer to separate but related cyber activity clusters.
