Analysis Summary
A GlobeImposter ransomware outbreak took place at a Financial services’ subsidiary company, resulting in encryption of a server and the NAS storage which hosted the virtual machines connected to them. Initially, a brute force RDP attack was launched on an admin account on the first compromised server, resulting in 1800 failed login attempts within 5 hours, prior to getting access. Once the access was gained, the attackers deployed advanced port scanner, credential stealing malware Mimikatz and a crypto-mining malware. The attackers then proceeded to deploy the ransomware, which, the researchers reported to be GlobeImposter. However, evidence of data exfiltration has not been found.
