Don't underestimate pro-Russia hacktivists, warns UK's cyber crew

The NCSC warns that pro‑Russian hacktivist groups (including NoName057(16), CARR, Z‑Pentest, and Sector16) are conducting denial‑of‑service attacks against UK local authorities and critical national infrastructure; although these attacks are often low in sophistication, they can disrupt essential services and impose financial and productivity costs, prompting recommendations for DDoS mitigation, CDNs, and resilience measures.
