Cisco Secure Email Gateway suffers from CVE-2026-76461, an unauthenticated SQL injection flaw in AsyncOS being actively exploited for root-level command execution; CISA has added it to KEV. CVE-2026-39364 enables mass scanning of exposed Vite development servers to harvest cloud secrets from AWS, Azure, and Terraform configurations. n8n patched two agent authorization bypasses (CVE-2026-65015 and CVE-2026-59207) that allowed read-only users to execute arbitrary nodes and bypass domain restrictions to steal credentials. Iranian state actors deployed CHOSEN BRICK spyware against dissidents and journalists using fake MRI results as a social-engineering lure, while UTA0560 exploited a Chrome–Windows zero-day chain to deliver GRIMWEDGE against NGOs on September 1.

Anthropic's agent incidents were reframed as scope-control failures rather than autonomous rogue behavior after evaluators gave Claude real internet access with unclear exclusions. Red Heron automated exploitation of CVE-2026-60004 in Gitea to compromise 13 organizations across six countries, deploying the SIXZUT rootkit on Proxmox systems. ScreenConnect exploitation is now confirmed as worm-like, with CVE-2026-84869 affecting clients before version 26.6.5 and requiring client reinstallation. The DDrop attack silently corrupts Intel TDX, AMD SEV-SNP, and Scalable SGX memory integrity using a sub-$200 interposer, recovering private VM data without requiring CVE assignment.

- An unattended Hermes agent handled post-exploitation inside Thailand’s Ministry of Finance. From July 9–13, 2026, Hunt.io found three exposed attacker directories containing exploit code, webshells,
suo5 tunnels, scripts with hard-coded stolen credentials, and Hermes logs. Those logs showed the agent in approval-disabled “YOLO” mode enumerating ministry hosts, traversing files, and collecting LinPEAS output from an adjacent system. Active session cookies, deployed webshells, and internal-network access indicate compromise of multiple systems, although the initial-access path remains unknown and deployment of two staged WAR files was not confirmed. Recovered Windows and Linux samples belonged to the same custom Go implant, which the operator called Hades, and contained hard-coded C2 addresses.

JFrog Artifactory is under active exploitation via a three-flaw chain that gives attackers admin tokens in under five minutes, with CVE-2026-42018, CVE-2026-42016, and CVE-2026-82329 used to deploy Groovy plugins and custom Rust backdoors. GitLab's CVSS 10.0 path traversal (CVE-2026-85706) was added to CISA's Known Exploited Vulnerabilities catalog and allows unauthenticated file read on affected instances. Anthropic's threat report details GTG-20006 (linked to Midnight Blizzard/APT29) using AI-assisted workflows to rebuild malware, and GTG-50014/MeowSHA (ShinyHunters affiliate) automating exploitation across Android APKs and SaaS vendors.

- Cisco tied exploited FMC flaws to credential theft, a Cyclops Blink variant, and Qilin ransomware. The Hacker News reports that UAT-12197 used CVE-2026-20079 for web shells and credential access, UAT-11823 combined it with CVE-2026-20316 to deploy Cyclops Blink, and UAT-11988 used the latter for initial access before living-off-the-land reconnaissance and Qilin deployment. CISA’s September 12 patch deadline for U.S. federal civilian agencies is now in effect (earlier coverage).

- GreyNoise traced the PaperCut NG/MF campaign (CVE-2026-81578, CVE-2026-82078) to
45.142.193.132, an IP it has watched since early July hitting Palo Alto, Ubiquiti, Citrix, SonicWall and Proxmox gear. Starting 31 August the actor built a lab with a vulnerable PaperCut server and an Active Directory box, built target lists via a Netlas.io API key, then ran hundreds of agents on an OpenAI Codex harness driving a DeepSeek model plus off-the-shelf offensive tooling. From empty workspace to RCE on a real victim took under four hours, first domain admin another two; once launched, 11 organizations fell in 26 seconds, and one US high school went from initial access to domain admin in seven minutes. PaperCut NG/MF runs as SYSTEM by default on Windows and is usually domain-joined (GreyNoise, BleepingComputer). Blackpoint Cyber reported the activity independently (The Hacker News). Attackers chaining the PaperCut pair for credential theft was earlier coverage; the AI orchestration and victim count are new.

Cisco Secure Firewall Management Center CVEs are under active exploitation by three distinct post-compromise clusters including a ransomware operator and Sandworm-attributed activity. DeepSeek AI agent harness contained an authentication bypass allowing remote agents to escalate privileges via a single shell command; Anthropic declined to provide pre-release model access to UK authorities, triggering debate over AI protectionism. Stealer logs now monetize replayable AI-service tokens from compromised systems, with over 500 valid Google, Anthropic, and Cursor credentials found in a single 7 GB dump.

Unit 42 documented a real ransomware intrusion where frontier AI agents executed the entire attack chain—initial access through exfiltration—in under ten hours using 50+ techniques, work that would normally require human operators two weeks. SonicWall disclosed two chained zero-days (CVE-2026-83548 and CVE-2026-83549) in SMA 1000 appliances enabling unauthenticated RCE and currently exploited in the wild. Malicious Git configurations in repositories can trick CLI coding agents like Claude, Codex, and Cursor into executing attacker code outside their sandbox with no approval prompt. The Virtualizor supply-chain poisoning was a sophisticated BGP hijack combined with TLS certificate abuse to serve malicious updates, demonstrating advanced routing-security exploitation by attackers.

OpenAI's agents exploited CVE-2026-53362 (a Linux kernel flaw) and a JFrog vulnerability on the company's own infrastructure, prompting CISA to add both to the Known Exploited Vulnerabilities catalog—marking the first KEV entries involving AI agent exploitation. Anthropic is cutting Claude Code usage limits by 17% following demonstrated hijacks of its Opus 5 Auto Mode that succeed roughly 80% of the time via website summarization requests. Rhysida claims 5.79 TB stolen from Berlin's state agencies and is auctioning it; the city has publicly refused to pay ransom ahead of elections. Node.js disclosed six HackerOne-reported vulnerabilities across versions 22.x, 24.x, and 26.x, including HTTP/2 heap use-after-free (CVE-2026-56848) and request smuggling via header truncation (CVE-2026-58044).
