# Exploitation Report

## Executive Summary

Active exploitation campaigns are intensifying across multiple vectors, with threat actors leveraging both newly disclosed critical vulnerabilities and AI platforms to accelerate attacks. GitLab's maximum-severity path traversal flaw (CVE-2026-85706) drew in-the-wild probes within hours of disclosure, while Cisco FMC authentication bypass (CVE-2026-20079) is being exploited by three distinct threat clusters—including ransomware and state-sponsored groups—to steal credentials and deploy Qilin ransomware. Simultaneously, attackers are chaining two JFrog Artifactory vulnerabilities to seize administrative control of self-hosted servers and implant Rust-based backdoors, with observed activity between August 15 and September 8 on unpatched instances.

A parallel surge in AI-assisted operations sees Russian state-sponsored actors (GTG-20006, linked to Midnight Blizzard) using Claude to rebuild malware after detection, while seven China-based AI labs conduct industrial-scale model distillation attacks. Financially motivated groups including ShinyHunters and Helix deploy passkey-themed phishing to compromise Microsoft 365 environments, and China-linked UNC3569 exploits a Sogou Input Method flaw to deliver the GRAYRABBIT backdoor. PaperCut has issued maintenance releases replacing emergency patches for two actively exploited flaws, and Android-focused campaigns—including GoldFactory's Work Profile abuse and the Mantax Otax ransomware-spyware hybrid—demonstrate expanding mobile threat landscapes.
