The double extortion model — encrypting data AND threatening to publish stolen files — means that even organizations with solid backups face reputational and regulatory exposure if exfiltration occurs. This matters because traditional recovery strategies focused solely on restoring from backups are no longer sufficient when sensitive data has already left the environment. Organizations must treat ransomware as both a business continuity crisis and a data breach simultaneously.","**Immediate actions:**\n- Audit and test offline\u002Fimmutable backup systems to ensure they cannot be encrypted or deleted by ransomware.\n- Deploy endpoint detection and response (EDR) tooling capable of identifying Rust-compiled binaries and anomalous file encryption activity.\n- Implement network-level data loss prevention (DLP) to detect and block large-scale exfiltration before double extortion becomes viable.\n\n**Long-term improvements:**\n- Enforce the principle of least privilege across all user and service accounts to limit lateral movement during an active intrusion.\n- Segment high-value data stores from general network access using micro-segmentation and zero-trust architecture.\n- Develop and regularly rehearse a ransomware-specific incident response playbook that addresses both encryption and data leak scenarios.\n\n**Detection measures:**\n- Enable robust logging of file system events, process creation, and outbound network connections to detect early-stage ransomware behavior.\n- Integrate threat intelligence feeds covering known ransomware IOCs (including DeadLock infrastructure indicators) into your SIEM platform.\n- Monitor for unusual access patterns to backup systems or shadow copy deletion commands as early ransomware precursor signals.",[12,13,14,15,16,17,18,19,20,21,22,23,24],"CIS Control 11 – Data Recovery","CIS Control 13 – Network Monitoring and Defense","CIS Control 3 – Data Protection","CIS Control 6 – Access Control Management","NIST SP 800-61 – Computer Security Incident Handling Guide","NIST SP 800-184 – Guide for Cybersecurity Event Recovery","NIST CSF RS.RP-1 – Response Planning","NIST CSF PR.DS-1 – Data-at-Rest Protection","GDPR Article 32 – Security of Processing","GDPR Article 33 – Notification of Personal Data Breach","ITIL Service Continuity Management","MITRE ATT&CK T1486 – Data Encrypted for Impact","MITRE ATT&CK T1567 – Exfiltration Over Web Service","published","2026-08-10T18:21:59.547127+00:00","2026-08-10T18:21:59.219+00:00",{"id":7,"url":29,"slug":30,"title":31},"https:\u002F\u002Fwww.microsoft.com\u002Fen-us\u002Fsecurity\u002Fblog\u002F2026\u002F08\u002F10\u002Fdeadlock-ransomware-breaking-down-a-rust-based-encryptor-with-decentralized-recovery-infrastructure\u002F","deadlock-ransomware-breaking-down-a-rust-based-encryptor-with-decentralized-reco-686d9c","DeadLock ransomware: Breaking down a Rust-based encryptor with decentralized recovery infrastructure",[33,39,45],{"id":34,"name":35,"slug":36,"description":37,"color":38},"182e11d5-57c4-444e-8ec8-4682ad60261b","Incident Response","incident-response","Slow detection, poor containment, missing playbooks","#14b8a6",{"id":40,"name":41,"slug":42,"description":43,"color":44},"c8b843a5-d5a7-41d1-8d3b-cabded09d2ef","Data Protection","data-protection","Unencrypted data, missing DLP, poor classification","#3b82f6",{"id":46,"name":47,"slug":48,"description":49,"color":50},"c8ff5d73-dec9-4911-88ee-ed016a89f3f4","Backup & Recovery","backup-recovery","No backups, untested recovery, ransomware impact","#f43f5e",[]]
