An Akira ransomware affiliate tried to use Windows Safe Mode against a victim’s defenses and accidentally undermined the ransomware run itself, according to The Register, citing an incident write-up by Huntress security operations analyst James Northey. The attacker forced a victim system to reboot into Safe Mode with Networking, a stripped-down startup mode that loads only essential drivers and services. The move appears to have had the intended effect of blocking many third-party security tools. But in this case it also kept the Akira encryptor from doing its main job: locking the endpoint’s files. That failure did not make the intrusion harmless. The Register reports that the attacker had already stolen credentials and data from file shares before the encryption attempt broke down. Northey cautioned that this was closer to a narrow technical failure than a defensive technique organizations can count on. The incident began in early August through a SonicWall Secure Sockets Layer virtual private network, according to the report. On August 4, the VPN recorded a credential-spray attack: a burst of failed login attempts using invalid credentials. Seven minutes later, one login succeeded with a valid VPN account that was not protected by multi-factor authentication. Once inside, the attacker used Remote Desktop Protocol to access the domain controller and queried Active Directory. Huntress described the enumeration as a broad collection of properties across users and computers in the domain, giving the intruder the map needed for lateral movement and a wider ransomware attempt. The attacker then moved to an application server and began staging data theft. The Register reports that the affiliate downloaded WinRAR to archive mapped file shares, then used s5cmd, an S3 transfer utility, to move stolen data to cloud storage. The operator also installed AnyDesk, configured it to start with Windows, and used the legitimate remote desktop tool for hands-on access and as a command-and-control channel. The malware drop included an executable named akira.exe, according to the report. About three hours into the intrusion, the attacker rebooted the machine into Safe Mode with Networking. That tactic is used by ransomware operators because Safe Mode can reduce interference from endpoint protection and other third-party tools. Here, the same reduced environment also appears to have deprived the encryptor of what it needed to execute properly. Northey warned that defenders should not generalize from the failure. The Register reports his assessment that a machine with more physical memory or a larger page file might have given the encryptor enough virtual memory to run, and that Akira developers or affiliates could change the encryptor or its Safe Mode launch process in a future intrusion. The clearest control in the reported chain is not Safe Mode. It is multi-factor authentication on VPN access. In this case, the successful entry followed a credential-spray event and used a valid account that lacked MFA, giving the operator the opening for domain enumeration, data theft, remote-tool deployment, and the failed encryption attempt. Who benefits: Organizations that enforce MFA on VPN access and watch for credential spraying, unusual Remote Desktop Protocol activity, Active Directory enumeration, and unexpected remote-access tools are better positioned to interrupt this chain early. Who's exposed: Victims relying on VPN credentials alone are exposed, especially where a valid account can be used after failed login bursts. Teams that assume endpoint security tools will remain active during attacker-forced reboot modes also face risk.
