Medusa Group G1051
Medusa Group has been active since at least 2021 and was initially operated as a closed ransomware group before evolving into a Ransomware-as-a-Service (RaaS) operation. Some reporting indicates that certain attacks may still be conducted directly by the ransomware’s core developers. Public sources have also referred to the group as “Spearwing” or “Medusa Actors.” Medusa Group employs living-off-the-land techniques, frequently leveraging publicly available tools and common remote management software to conduct operations. The group engages in double extortion tactics, exfiltrating data prior to encryption and threatening to publish stolen information if ransom demands are not met. For initial access, Medusa Group has exploited publicly known vulnerabilities, conducted phishing campaigns, and used credentials or access purchased from Initial Access Brokers (IABs). The group is opportunistic and has targeted a wide range of sectors globally.
Methodology
Relevance is a match on your industry sector and technology stack against the MITRE ATT&CK v19.1 group graph (174 groups, 821 software families, 56 campaigns). It is computed deterministically from that data, with no language model in the request path. It is a relevance match, not threat-intelligence probability data: it tells you which documented actors and techniques are worth emulating for an org like yours, not a forecast that any specific group will act.
TurboPentest can autonomously exercise 3 of 57 of this actor's documented techniques today (5%). 17 are out of scope for automated testing (social engineering, denial of service, physical).

These counts are computed from the vendored MITRE ATT&CK graph and the published coverage map, and are reproducible from source.
