Rhadamanthys v0.5.0 - a deep dive into the stealer’s components
Rhadamanthys v0.5.0 - a deep dive into the stealer’s components
  • The Rhadamanthys stealer is a multi-layer malware, sold on the black market, and frequently updated. Recently the author released a new major version, 0.5.0. In the new version, the malware expands its stealing capabilities and also introduces some general-purpose spying functions. A new plugin system makes the malware expandable for specific distributor needs. The custom executable formats, used for modules, are unchanged since our last publication (XS1 and XS2 formats are still in distribution). Check Point Research (CPR) provides a comprehensive review of the agent modules, presenting their capabilities and implementation, with a focus on how the stealer components are loaded and how they work.

Into the Trash: Analyzing LitterDrifter
Gamaredon, also known as Primitive Bear, ACTINIUM, and Shuckworm, is a unique player in the Russian espionage ecosystem that targets a wide variety of almost exclusively Ukrainian entities. While researchers often struggle to uncover evidence of Russian espionage activities, Gamaredon is notably conspicuous. The group behind it conducts large-scale campaigns while still primarily focusing on regional targets. The Security Service of Ukraine (SSU) identified the Gamaredon personnel as Russian Federal Security Service (FSB) officers.
