Summary

Hide ▲

ShadowSyndicate, a cybercrime cluster linked to multiple ransomware groups, has expanded its infrastructure. Researchers identified new technical markers, including reused SSH fingerprints, that connect dozens of servers to the same operator. The group has been active since 2023 and maintains a consistent infrastructure pattern. New SSH fingerprints and server transfers between internal clusters were observed, linking previously known servers to newly deployed infrastructure. The group uses commercial red-team frameworks and open-source post-exploitation tools, with ties to ransomware groups like Cl0p, ALPHV/BlackCat, and Ryuk. Group-IB recommends monitoring IoCs, autonomous systems, and unusual login activities to defend against this threat.
