Researchers attributed an ongoing cyber-espionage campaign to DeathStalker with high confidence, saying the group has targeted foreign exchange and cryptocurrency trading companies since at least Q2 2020 using its VileRAT toolchain. The intrusion chain evolved over time from spear-phishing emails carrying malicious Google Drive-hosted shortcut files to email- and chatbot-delivered DOCX documents that retrieved macro-enabled DOTM remote templates, ultimately deploying VileDropper, VileLoader, and the Python-based VileRAT remote access trojan.
The operators repeatedly refined the malware to evade detection and frustrate analysis, using techniques including VBA stomping, XOR-encoded data hidden in Office objects, JavaScript anti-analysis checks, multi-stage in-memory loading, and Python bytecode obfuscation intended to break decompilers. Investigators also linked the activity to a large infrastructure footprint involving hundreds of domains and IP addresses, many associated with AS42159 (DELTAHOST UA) in the Netherlands from late 2021 onward, and said a rise in related samples and infrastructure from March 2022 pointed to intensified compromise attempts against less mature organizations.

4 events from the most recent confirmed update back to the earliest known activity.
On 2025-12-09, Securelist published research describing the ongoing VileRAT espionage campaign, its evolving infection chain, and its attribution to DeathStalker with high confidence.
The report says researchers saw increased VileRAT-related samples and infrastructure from March 2022, indicating intensified compromise attempts by the operators.
From late 2021 onward, the campaign used extensive infrastructure including hundreds of domains and IP addresses largely tied to AS42159 (DELTAHOST UA), according to the report.
Securelist reports that the VileRAT-centered cyber-espionage campaign attributed with high confidence to DeathStalker has targeted foreign exchange and cryptocurrency trading companies since at least Q2 2020.
