The company could not identify the attackers or their initial access vector, suggesting insufficient logging and monitoring to support post-incident forensics. Recovery took several days and some customer issues persisted even after main services were restored, pointing to gaps in tested backup and recovery procedures. When a cloud provider is the victim, every tenant becomes an indirect victim, making provider-level resilience a critical concern for any business that outsources infrastructure.","**Immediate actions:**\n- Audit all backup systems to confirm backups are offline or immutable and cannot be encrypted by ransomware\n- Review and test restoration runbooks to ensure recovery time objectives can realistically be met after a large-scale encryption event\n\n**Long-term improvements:**\n- Implement network segmentation within cloud infrastructure so that a compromised node cannot freely spread ransomware to all customer environments\n- Establish and rehearse a formal incident response plan that includes customer communication timelines and forensic logging retention\n- Require cloud service providers to demonstrate third-party security audits and defined recovery SLAs before onboarding\n\n**Detection measures:**\n- Deploy centralised logging and behavioural anomaly detection to identify lateral movement and mass file-encryption activity early\n- Set automated alerts for abnormal storage write patterns that may indicate ransomware encryption in progress",[12,13,14,15,16],"NIST CSF 2.0 RC.RP: Incident Recovery Plan Execution","NIST SP 800-53 CP-9: System Backup","CIS Control 11: Data Recovery (v8)","NIS2 Article 21(2)(c)","NIS2 Article 21(2)(b)",{"NIS2 Article 21(2)(b)":18,"NIS2 Article 21(2)(c)":19,"CIS Control 11: Data Recovery (v8)":20,"NIST SP 800-53 CP-9: System Backup":21,"NIST CSF 2.0 RC.RP: Incident Recovery Plan Execution":22},"This point requires effective incident handling procedures, including detection and response; the provider's inability to identify the entry vector indicates logging and forensic capabilities were inadequate to support proper incident handling.","This point requires business continuity and crisis management measures, including backup and disaster recovery; the days-long disruption across customer businesses reflects insufficient continuity planning at the provider level.","CIS Control 11 mandates tested, offline or immutable backups; the extended recovery time strongly suggests backup integrity or recovery procedures were not regularly validated.","CP-9 requires organisations to protect backup information from ransomware-style destruction; encrypted infrastructure suggests backups were either absent, insufficient, or not isolated from the attack surface.","This category requires that recovery plans are executed and refined after incidents; the multi-day outage and lingering customer issues indicate recovery planning and execution were inadequate.","published","2026-11-13T15:20:40.902189+00:00","2026-11-13T15:20:40.884+00:00",{"id":7,"url":27,"slug":28,"title":29},"https:\u002F\u002Ftherecord.media\u002Fbelarus-cloud-provider-activecloud-ransomware-attack","ransomware-attack-on-belarusian-cloud-firm-disrupts-businesses-for-days-9b8698","Ransomware attack on Belarusian cloud firm disrupts businesses for days",[31,37],{"id":32,"name":33,"slug":34,"description":35,"color":36},"182e11d5-57c4-444e-8ec8-4682ad60261b","Incident Response","incident-response","Slow detection, poor containment, missing playbooks","#14b8a6",{"id":38,"name":39,"slug":40,"description":41,"color":42},"c8ff5d73-dec9-4911-88ee-ed016a89f3f4","Backup & Recovery","backup-recovery","No backups, untested recovery, ransomware impact","#f43f5e",[],[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},"immutable-backup","Immutable backup and recovery","Ransomware cannot delete or encrypt your way back.",{"slug":54,"name":55,"problem":56},"incident-response-retainer","Incident response retainer","Experts are on call before the worst day, not searched for during it."]
