The NCSC has previously warned over the growth in mercenary activity by Russia-supporting groups acting on ideological grounds - these are not necessarily the threat groups rejoicing in names such as Cozy Bear that are officially backed by the Kremlin, rather more technically unsophisticated groups acting of their own accord.
There continues to be a heightened threat from state-aligned actors to operational technology (OT) operators. The NCSC urges all OT owners and operators, including UK essential service providers, to follow the recommended mitigation advice now to harden their defenses.
