Why did NCSC publish an advisory on FSB Centre 16?
Background
The UK's NCSC and 18 partner agencies published a joint advisory on 9 July 2026 attributing a router-hijacking campaign that abused the SNMP protocol on network edge devices to FSB Centre 16, explicitly distinguishing it from the GRU Unit 26165/APT28 DNS-hijacking campaign named in April 2026.
Centre 16 (also known as Center 16 or the 16th Centre, and historically as military unit 71330) is the FSB's signals-intelligence directorate. It has long been linked by Western agencies to the Berserk Bear / Dragonfly / Energetic Bear intrusion activity, which has targeted energy and industrial-control networks.
The distinction from APT28 matters: FSB and GRU units run separate operations with different tradecraft and targets, and conflating them muddies attribution across the Russia-linked cyber campaigns Lowdown is tracking in both this topic and the wider Russia-Ukraine conflict.
