Storm-0501, a financially motivated threat actor, has targeted government, manufacturing, transportation, and law enforcement sectors in the U.S. with ransomware attacks. They use weak credentials, remote code execution vulnerabilities, and various tools for lateral movements and data exfiltration. The group is also linked to the deployment of Embargo ransomware in a ransomware-as-a-service (RaaS) model.
From the meeting notes, it is clear that the threat actor known as Storm-0501 has been actively targeting various sectors in the U.S. including government, manufacturing, transportation, and law enforcement, using multi-stage ransomware attacks. This actor primarily focuses on compromising hybrid cloud environments, performing lateral movement from on-premises to the cloud, data exfiltration, credential theft, and deploying ransomware.
Storm-0501 employs various methods for initial access including weak credentials, over-privileged accounts, and exploiting known vulnerabilities in internet-facing servers. Once inside the network, the actor conducts extensive discovery operations, deploys remote monitoring and management tools, and attempts to gain access to more accounts using techniques such as brute-force attacks.
Furthermore, Storm-0501 has been observed using Cobalt Strike to move laterally across the network, exfiltrating data to the MegaSync public cloud storage service, and creating persistent backdoor access to the cloud environment. The group is also reported to use stolen credentials to move laterally from on-premises to the cloud and deploy ransomware.
Additionally, it is noted that Storm-0501 is part of a ransomware-as-a-service (RaaS) platform, specifically employing Embargo ransomware which utilizes double extortion tactics. This tactic involves encrypting victim’s files and threatening to leak sensitive data unless a ransom is paid.
In conclusion, the threat actor Storm-0501 poses a significant risk to organizations, especially those with hybrid cloud setups, and it is important for businesses to be vigilant and take proactive measures to secure their systems and data.
