The Russian-aligned Lunex Malware-as-a-Service platform utilizes a complex four-stage attack chain, including BYOVD-based EDR neutralization, to deploy a sophisticated information stealer and C2 agent.

The MikroTrick exploit chain combines an SSH state-machine flaw with a login argument injection bug to achieve unauthenticated administrative control over MikroTik RouterOS devices.

The researcher Nightmare Eclipse (aka MSNightmare) has released multiple proof-of-concept exploits targeting Windows Defender, Kaspersky, Avast, CrowdStrike, and NVIDIA drivers to achieve local privilege escalation or denial-of-service.

Chinese threat actor UTA0565 utilized chained Chrome and Windows zero-day exploits through spoofed domains to deliver a custom obfuscated malware named CLEANGULP targeting government entities.

Adversaries can achieve SYSTEM privilege escalation by planting a malicious DLL at a non-existent ProgramData path referenced by a dangling COM registration and triggering it via custom COM marshaling.

The Gentlemen threat actor group is utilizing the cross-platform TukTuk C2 framework and BYOVD techniques to neutralize EDR solutions while targeting global technology and healthcare sectors.

A financially motivated operator using the persona 'SOUL - Red Team Operator' employs autonomous AI harnesses (Hermes, Strix, Cairn) to breach online retailers, steal credit card data, and inject skimmer scripts.

Chinese threat actors UTA0560 and JungleBamboo exploited a 'patch-gap' zero-day chain in Chrome and Windows to deploy the GRIMWEDGE backdoor and LONGTALE credential stealer.
