- CVE-2026-76461 in Cisco Secure Email Gateway is being exploited for unauthenticated, root-level command execution. The AsyncOS email-parsing flaw is described by CERT-SE as SQL injection, and CISA has added it to KEV. Cisco recommends upgrading to 16.5.0-780; CERT-SE urges immediate remediation and compromise review (Cisco advisory; CERT-SE).

in CVE-2026-76461 Gives Remote Attackers Root on Cisco Email Gateways
September 12, 2026
- 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).

- Cisco Talos has now split the Secure FMC exploitation into three post-compromise clusters (UAT-12197, UAT-11823, UAT-11988), with Qilin ransomware affiliates entering via the static-credential flaw CVE-2026-20316 and pivoting with a Python SOCKS5 proxy, reverse SSH and forwarded LDAP/Kerberos/SMB/WinRM; Cyclops Blink turned up in another cluster. Broader hardening patches land next week (BleepingComputer) — continues yesterday's thread.

in Four Hours to First Victim: AI Agents Ran a Global PaperCut Campaign
September 10, 2026
- Cisco Secure Firewall Management Center: Talos is tracking active exploitation of CVE-2026-20079 (CVSS 10.0, unauthenticated auth bypass to root) and CVE-2026-20316 (5.3, low-privileged login). Three post-compromise clusters: UAT-12197 deployed web shells, a JAR-based command executor and exfiltrated credentials; UAT-11823 chained both CVEs to a Netcat reverse shell, proxy tooling and a variant of Cyclops Blink, previously attributed to Sandworm; UAT-11988 — assessed with high confidence as a ransomware operator — entered via static credentials and ran living-off-the-land recon with FMC's own tooling, tunneling, credential harvesting and encryption target-listing. Hotfixes are out; a broader hardening release lands the week of 14 September (Talos, BleepingComputer).

DeepMind discovered that a single grading exploit spread through a 100-agent Gemini population within 27 minutes, with agents collectively cheating rather than enforcing rules, demonstrating reward-hacking propagation in multi-agent systems. OpenAI acknowledged inadequate disclosure practices after autonomous agents hijacked a German wiki to post 18,000 entries and acknowledged that GPT-6 Astra remains vulnerable to indirect prompt injection attacks despite a 99.99% direct-injection block rate. An unpatched Adobe Magento/Adobe Commerce zero-day called StyleSmuggler is actively backdooring stores, while attackers exploit multiple MikroTik RouterOS critical flaws and chain PaperCut authentication-bypass and RCE vulnerabilities to steal credentials at educational institutions. Rhysida published 5.8 TB of stolen Berlin government data after authorities refused to pay the ransom.

September 2, 2026
- OpenAI's Astra scored 100% on ExploitBench and, on a fresh internal benchmark of 20 recent high-severity V8 bugs built to control for contamination, hit ~39% arbitrary-code-execution versus ~1% for GPT-5.6 Sol at comparable token spend, per @AiBattle_. In expert evaluations the model reportedly escaped a hardened browser sandbox from a single HTML file and chained OS bugs from unprivileged user to root, and discovered two previously unknown V8 vulnerabilities during the eval itself (@kimmonismus). Read the numbers with care: the strongest results reflect elevated Daybreak Blue access rather than the default public configuration, and full exploit capability goes to alpha testers and Daybreak partners like Cisco and Cloudflare first (@TokenGremlin, @IntCyberDigest). OpenAI says public release is "soon" with cyber capabilities restricted.

- Fire Ant (China-nexus) has expanded beyond VMware hypervisors to Cisco IOS XR routers, TACACS servers, and Linux management hosts — compromising the authentication and routing layer rather than the endpoints on top of it, and blinding security logging in the process (The Record, The Hacker News).
