Response to CISA Advisory (AA26-222A): #StopRansomware: Gunra Ransomware
What it means
CISA e partner hanno emesso un avviso su Gunra, un ransomware che utilizza un modello di doppia estorsione e opera attraverso un programma RaaS. L'attacco include l'esfiltrazione di dati e minacce di pubblicazione. La vulnerabilità è sfruttata attivamente, con un'offensiva strutturata. La patch è disponibile ma non indicata nel testo.
Why it matters
Per le PMI italiane, Gunra rappresenta un rischio elevato per la disponibilità dei dati e la reputazione aziendale. La doppia estorsione può portare a perdite economiche significative e danni alla fiducia dei clienti.
Recommended actions
- Implementare controlli di accesso basati su MFA per limitare l'accesso non autorizzato
- Eseguire backup regolari e verificare la loro integrità
- Monitorare le comunicazioni tramite Tor e bloccarle
- Configurare regole di firewall per limitare l'accesso a sistemi interni
- Eseguire aggiornamenti di sistema e patch disponibili
- Monitorare le attività di esfiltrazione dati e interromperle tempestivamente
Potential operational benefits
- Traduzione dell'advisory in verifiche difensive autorizzate
- Confronto tra comportamenti avversari e copertura dei controlli
- Evidenze ripetibili per il piano di miglioramento
Translation in progress
The official content is available in the original language. The Italian version will be published once automated checks are complete.

CISA and partners issued a joint advisory detailing Gunra ransomware’s evolving tactics and double-extortion operations. AttackIQ emulations help organizations validate defenses against the adversary behaviors observed in Gunra attacks. The post Response to CISA Advisory (AA26-222A): #StopRansomware: Gunra Ransomware appeared first on AttackIQ . On August 10, 2026, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Department of Defense Cyber Crime Center (DC3), National Security Agency (NSA), U.S. Secret Service (USSS), and Republic of Korea’s National Police Agency (KNPA) released a joint advisory to alert organizations to the emerging Gunra ransomware threat and to provide detection and mitigation guidance. This joint CSA is part of CISA’s ongoing #StopRansomware effort to provide defenders with intelligence and recommendations to help organizations identify, mitigate, and respond to ransomware activity. Gunra is a ransomware strain that emerged in April 2025. Developed in C/C++ and reportedly derived from leaked Conti ransomware source code, Gunra has since been observed targeting organizations across multiple industries. In early 2026, the group expanded its operations through a structured ransomware-as-a-service (RaaS) affiliate program advertised on underground forums. The program provides affiliates with access to a management panel, configurable ransomware builders, cross-platform payloads, and supporting documentation. Gunra operates a double-extortion model in which sensitive data is exfiltrated before systems are encrypted, with victims threatened with publication of their stolen information through a dedicated data leak site. Ransom negotiations are conducted through a Tor-based portal. According to the advis
