Threat actors leveraged tools such as GOST (for tunneling) and Rclone (for data exfiltration), both of which leave distinct 'toolmarks' that can be recovered post-incident — but only if native logging was enabled and retained. This highlights a critical dependency: without proactive telemetry collection, incident responders are forced into a reactive, evidence-scavenging posture that slows containment and increases damage. Organizations without EDR are not invisible to attackers, but they are largely invisible to themselves. Comprehensive logging is not a luxury — it is a foundational control that directly affects both detection speed and recovery quality.","**Immediate actions:**\n- Deploy an EDR solution across all endpoints to ensure real-time telemetry and behavioral detection capabilities.\n- Audit current Windows Event Log settings and ensure critical event categories (logon events, process creation, PowerShell, network connections) are enabled and forwarded to a central SIEM.\n\n**Long-term improvements:**\n- Establish a minimum log retention policy of 90–180 days to support post-incident forensic investigations.\n- Implement network segmentation to limit lateral movement opportunities and restrict tools like Rclone from reaching external exfiltration endpoints.\n- Conduct regular threat-hunting exercises using known ransomware TTPs (e.g., MITRE ATT&CK) to proactively identify toolmarks and anomalous behavior.\n\n**Detection measures:**\n- Create SIEM detection rules specifically for known dual-use tools such as Rclone, GOST, and similar tunneling\u002Fexfiltration utilities.\n- Establish baseline behavioral profiles for endpoints and alert on deviations such as unusual outbound traffic volumes or rare process parent-child relationships.",[12,13,14,15,16,17,18,19,20,21],"CIS Control 8: Audit Log Management","CIS Control 10: Malware Defenses","CIS Control 13: Network Monitoring and Defense","NIST SP 800-61 Rev. 2: Computer Security Incident Handling Guide","NIST SP 800-92: Guide to Computer Security Log Management","NIST DE.CM-1: Network and system monitoring","NIST DE.AE-3: Event data aggregated and correlated","MITRE ATT&CK T1567.002: Exfiltration to Cloud Storage (Rclone)","MITRE ATT&CK T1572: Protocol Tunneling (GOST)","ITIL: Event Management \u002F Incident Management practices",{},"published","2026-10-08T12:21:27.847813+00:00","2026-10-08T12:21:27.762+00:00",{"id":7,"url":27,"slug":28,"title":29},"https:\u002F\u002Fwww.itsecurityguru.org\u002F2026\u002F10\u002F08\u002Fno-edr-no-problem-how-huntress-rebuilt-an-akira-ransomware-attack-from-forensic-leftovers\u002F?utm_source=rss&utm_medium=rss&utm_campaign=no-edr-no-problem-how-huntress-rebuilt-an-akira-ransomware-attack-from-forensic-leftovers","no-edr-no-problem-how-huntress-rebuilt-an-akira-ransomware-attack-from-forensic--944524","No EDR, no problem: how Huntress rebuilt an Akira ransomware attack from forensic leftovers",[31,37],{"id":32,"name":33,"slug":34,"description":35,"color":36},"1732a005-556e-411c-a9db-5edec3058571","Logging & Monitoring","logging-monitoring","Missing logs, no alerting, blind spots","#a855f7",{"id":38,"name":39,"slug":40,"description":41,"color":42},"182e11d5-57c4-444e-8ec8-4682ad60261b","Incident Response","incident-response","Slow detection, poor containment, missing playbooks","#14b8a6",[],[45,49,53],{"slug":46,"name":47,"problem":48},"endpoint-detection-response","Endpoint detection and response (EDR and XDR)","Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.",{"slug":50,"name":51,"problem":52},"log-management","Log management and security data pipelines","Security logs are so expensive to collect and keep that teams drop the ones they need when an incident happens.",{"slug":54,"name":55,"problem":56},"immutable-backup","Immutable backup and recovery","Ransomware cannot delete or encrypt your way back."]
