Background

FSB Centre 16 is a unit of Russia's Federal Security Service. On 9 July 2026, the UK's National Cyber Security Centre and 18 partner agencies published a joint advisory attributing an SNMP-based router-hijacking campaign to the unit, distinguishing it from a separate group named over an earlier, April 2026 hijacking campaign that used a different technique.

The Centre 16 campaign exploited weak or default credentials on network gear rather than a software vulnerability, a technique that requires no new code from the attacker, only unremediated configuration on the victim's own equipment.

No further detail on Centre 16's structure, targeting priorities or scale is yet public beyond the attribution itself, and this page will stay short until further reporting names a specific incident or victim set tied to the unit.
