FSB’s matryoshka #2/3 – Gamaredon’s gifts that keeps unpacking – GammaLoad 0 Gamaredon, an FSB-linked cyberespionage group, employs a sophisticated multi-stage malware called GammaLoad targeting Ukrainian government, military, and critical infrastructure. GammaLoad uses VBScript loaders in three stages to maintain persistent access, leveraging legitimate platforms like Telegram and Telegraph for command and control. It abuses Windows features such as Alternate Data Streams and scheduled tasks to evade detection and establish persistence. The final payload, GammaSteel, is delivered via obfuscated PowerShell scripts. This layered 'matryoshka' approach allows flexible deployment of arbitrary payloads while minimizing visibility.
