Russia-Linked Hackers Used New Mesh Network Backdoor in Destructive Ukraine Attack
Sandworm and UAC-0099 jointly deployed a mesh-network backdoor in a destructive wiper attack on Ukrainian logistics — a C2 innovation that could complicate detection if the tactic migrates to EU targets.
Summary written by editorial AI · Source link below
The Russian state-sponsored hacking group Sandworm teamed up with another threat actor to carry out a destructive wiping attack targeting a Ukrainian logistics company last year.
According to ESET, the attack involved UAC-0099 (aka Earth Sirrush) obtaining initial access to the target on July 16, 2025, via a spear-phishing email bearing a malware-laced attachment that led to the deployment of
Editorial Analysis
Mesh-based C2 architectures are harder to sever than traditional hub-and-spoke models; if adopted more broadly by Russian threat actors, EU logistics and critical infrastructure could face more resilient intrusions.
Review detection capabilities for peer-to-peer lateral communication patterns and ensure wiper-response playbooks are current.
Russian state hackers are evolving their persistence tools with mesh-network backdoors, raising the bar for detection and response across sectors they may target next.
