Qilin / Agenda — Rust-based ransomware-as-a-service; Q3 2025 German operational tempo tripled (GTIG); 23 Q1 2026 healthcare claims

Current state: GTIG's Europe data-leak landscape (§ 6) documented Qilin tripling Q3 2025 operational tempo in Germany; Die Linke (Germany federal political party) confirmed Qilin encryption with 1.5 TB exfiltrated (covered 2026-05-08), state DPA notified — Qilin German activity continues into 2026-Q2. No public-claim shift or victim-list expansion beyond Die Linke this week. Outstanding question: whether Qilin's targeting of political and civil-society organisations expands into other 2026 EU election cycles.

W1 horizon research added Q1 2026 healthcare quarterly context to the Groupe 3R item in § 1. Across Q1 2026, Akira posted 84 victims in March alone (second-most-active month on record) and claimed 5 healthcare victims; Qilin led healthcare at 23 claims (with RENAFAN GmbH and Suchthilfe direkt Essen gGmbH as Qilin's confirmed German victims), and The Gentlemen at 10 healthcare claims (Comparitech Q1 2026 Healthcare, 2026-04-29 · CyberMaxx Q1 2026). Akira's documented attack chain for healthcare: initial access via unpatched VPN (Cisco ASA, SonicWall, Fortinet) or compromised RDP credentials; lateral movement via T1021.001 Remote Services: Remote Desktop Protocol and T1047 Windows Management Instrumentation; LSASS credential harvesting via comsvcs.dll / Mimikatz; AV termination via PowerTool weaponising the Zemana AntiMalware driver (BYOVD); data exfiltration; double extortion. The cross-finding for Swiss / DACH operators reading after Groupe 3R: at least two ransomware-as-a-service operators (Akira and Qilin) are hitting European healthcare in Q1–Q2 2026 via the edge-device / unpatched-VPN attack surface, and the operator that hits a given hospital is less salient defensively than the shared initial-access funnel they exploit.

The German federal party Die Linke confirmed in April 2026 that the Qilin ransomware group (also known as Agenda, a Rust-based RaaS platform known for double extortion) encrypted and exfiltrated its systems, with the gang claiming 1.5 TB of internal data. The party's data protection officer notified the responsible Landesdatenschutzbehörde (state DPA). Die Linke issued a victim statement acknowledging operational disruption; no ransom figure has been publicly disclosed. Qilin has targeted political parties and civil-society organisations across Western Europe since 2023. This breach is approximately four weeks old but has not been previously covered in this brief series.
