Exploitation & threats
- watchTowr details a PaperCut pre-auth RCE chain exploited in the wild and repeated patch bypasses. PaperCut said on 27 August 2026 that 26.0.3 was being exploited and first published IOCs without a patch. watchTowr reproduced CVE-2026-81578 (authentication bypass) plus CVE-2026-82078 (post-auth RCE), then found bypasses WT-2026-0141 through WT-2026-0143; CVE-2026-82077 was fixed in 26.0.5 on 10 September 2026.
- CISA added five Flax Typhoon-exploited flaws to the KEV catalog, with a federal patch deadline of October 11. The additions are CVE-2015-3306 (ProFTPD), CVE-2021-3199 (ONLYOFFICE Docs), CVE-2023-22894 (Strapi), CVE-2016-3081 (Apache Struts), and CVE-2015-5477 (ISC BIND).

- Attackers exploit max-severity SonicWall SMA1000 flaw CVE-2026-102255 three days after patch; Previdian honeypots captured matching exploitation attempts. The pre-auth SSRF is in the Appliance WorkPlace interface on SMA1000 6210, 7210, and 8200v and lets unauthenticated attackers reach an internal service. See CVE-2026-102255 (CVSS 10).
- US authorities seized China-linked Integrity Tech tools Microscan and FishHub used to hack critical infrastructure. Microscan, via c0cc.cc and active since at least 2017, ran more than 1,300 scripts against OpenSSL, WordPress, Jenkins, and Apache Struts, backed by a Mirai IoT botnet whose June 2024 database listed over 1.2 million entries. FBI seized seven domains powering Flax Typhoon's Microscan and FishHub tools used against U.S. and Taiwanese critical infrastructure and universities, including a South Carolina power company and airports in Japan and Poland.
- GhostAction compromised maintainer accounts to plant credential-stealing GitHub Actions workflows in tens of thousands of repositories. Socket said more than 500 accounts had committed the workflow. A second count says GhostAction hit 346 GitHub repositories, including Uber's, after henrywoo and kitao added a fake security-audit workflow on October 8 that posts CI/CD secrets to 193.32.204[.]199.
- Attackers exploit unpatched AhsayCBS flaws to plant JSP webshells and XMRig miners at five organizations. Huntress saw attacks on 7 October 2026 against at least five organizations, including MSPs, chaining CVE-2026-105133 and CVE-2026-105134. Miners disguised as edge.exe persist via a service named MicrosoftEdgeUpdateSvc. Versions through 10.3.4 remain affected, with public exploit code since NIST’s October 4 disclosure.
- Warden Stealer, a Rust malware-as-a-service, harvests tokens and prompts from Claude, Codex, Grok, and Cursor. Also tracked as CallbackBeaver, it has been advertised on Russian-language forums since August 2026; version 1.9 (29 September) also targets browsers, wallets, password managers, and VPN clients.
- A trojanized Terraform AWS provider installs FLATROOF and ROOFDECK malware on developer macOS, Linux, and Windows systems. Zscaler ThreatLabz described a July 2026 campaign using terraform-provider-awsbeta_v1.0.0; a companion analysis treats the operators as suspected North Korean hackers.

Agents also submitted 20 incomplete State Department visa applications; none were processed.
- Zenity Labs showed one prompt could steal AWS AgentCore IMDS credentials and hijack regional agents. A chat-only user could obtain temporary IMDSv1 credentials for an overprivileged role covering AgentCore resources in the account and region.

Watchlist
- Federal systems have until October 11 to patch the five Flax Typhoon KEV flaws; allies’ October 8 alert also ties Integrity Technology Group to that activity.
- PaperCut bypass IDs WT-2026-0141 through WT-2026-0143 mean a 26.0.5 install may not be the end of the chain — confirm the latest vendor build.
- AhsayCBS through 10.3.4 is still unpatched, with a public exploit and active webshell and miner installs at MSPs.
- GhostAction is described as ongoing; rotate CI secrets in any repo that received the fake security-audit workflow.
- Qilin continued listing victims after the Germany/Japan arrest; today’s leak-site set includes new Qilin names.
