New Tomiris tools and techniques: multiple reverse shells, Havoc, AdaptixC2

Kaspersky researchers uncovered new malicious operations by the Tomiris threat actor targeting foreign ministries, intergovernmental organizations, and government entities. The attacks, which began in early 2025, show a shift in tactics with increased use of implants leveraging public services like Telegram and Discord as command-and-control servers. The group employs various programming languages including Go, Rust, C/C#/C++, and Python to develop reverse shell tools. Some infections lead to the deployment of open-source post-exploitation frameworks such as Havoc and AdaptixC2. The campaign primarily focuses on Russian-speaking users and entities, with additional targets in Central Asian countries.
