cerberimposter
Intelligence Profile
Cerber Imposer is a post-2019 rebrand of the Cerber ransomware family, resurfacing in late 2021 with updated targeting of enterprise environments. Unlike its classic counterpart, Cerber Imposer utilizes the .locked file extension and includes a unique recovery note named __$$RECOVERY_README$$__.html. It does not reuse the original Cerber codebase; instead it borrows branding while operating under new cryptographic implementations and deployment tactics. Threat actors have leveraged known remote code execution vulnerabilities in Atlassian Confluence (CVE-2021-26084) and GitLab (CVE-2021-22205) to deliver this ransomware. The rebranded variant has compromised servers in the U.S., Germany, China, and Russia, indicating a broader scope of targeting than originally seen with early Cerber campaigns. <br/>
