Russia-linked LAUNDRY BEAR exposed in phishing campaign

23 July 2026 elevated threat government-nationaldefense

UK NCSC and international partners attribute a zero-click phishing campaign against Western organisations to a newly named Russian state-supported group, LAUNDRY BEAR.

The UK's National Cyber Security Centre (NCSC), part of GCHQ, together with international partners, has publicly attributed a targeted phishing campaign to a Russian state-supported threat group tracked as LAUNDRY BEAR. The advisory describes the activity as 'zero-click' phishing, targeting Western organisations, though the published notice provided does not disclose specific victim sectors, malware samples, or technical indicators of compromise.

The disclosure functions primarily as a public attribution and warning rather than a detailed technical advisory. Defenders in government, defense, and allied Western institutions should treat this as confirmation of ongoing Russian state-sponsored targeting via phishing techniques and should review authentication and session-security controls, as 'zero-click' phishing campaigns often rely on token theft or session hijacking rather than requiring user interaction with malicious payloads. Organisations are advised to monitor for further technical guidance from NCSC and partner agencies as it becomes available, and to reinforce email security, conditional access policies, and monitoring for anomalous authentication events consistent with credential or session-token compromise.

Detection guidance

Anomalous Authentication Following Phishing Indicators

ATT&CK T1528

Detects authentication events with characteristics consistent with stolen or hijacked session tokens: logins from unusual geographies, impossible travel times, or new device fingerprints shortly after phishing campaign indicators. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

description: Detects authentication events consistent with stolen application access
  tokens or session hijacking - logins from unexpected locations, impossible travel
  times, or new devices shortly after potential phishing exposure. Zero-click phishing
  campaigns often bypass user interaction but result in token theft; this rule correlates
  suspicious auth patterns that indicate session compromise rather than credential
  entry.

Suspicious Phishing-Associated Network Beaconing to Rare Destinations

ATT&CK T1566

Detects outbound network connections to rare or newly observed destination IPs/domains shortly after phishing campaign detection, consistent with C2 or data exfiltration tied to token theft. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.
