P1 · AhsayCBS CVE-2026-105133/105134 exploited to plant JSP webshells, XMRig miner, Python C2 implant

Huntress analyzed three Windows AhsayCBS servers breached Oct 8-11, 2026 via an auth bypass and unauthenticated SYSTEM RCE through /rps/api/json/UpdateReceivers.do. The operator planted five JSP webshell families (including a PNG-steganography loader and a signed-API shell), an XMRig miner relaunched by a SYSTEM scheduled task every minute, a MachineGuid-keyed Python implant launched from a Run key, tunneling tools (gost, chisel), RMM tools, Defender exclusions, and a NetExec-style Veeam credential query. Hunt for cbssvcX64.exe spawning cmd.exe, new .jsp files in webapps\cbs and webapps\rps, ahsay_* and Linux-style folders at the drive root, the kvm task, and python.exe under the SYSTEM profile.

P1 · CISA adds OpenSSH CVE-2026-123158, GPUStack CVE-2026-102895, FreeSWITCH CVE-2026-116779 and IBM Aspera Faspex CVE-2026-123218 to KEV; no confirmed compromises stated in sources — update to 2026-11-09's story

CISA added four vulnerabilities to the KEV catalog on 2026-11-09 with a 2026-11-12 due date: OpenSSH CVE-2026-123158 (authentication bypass on Linux builds, with Alpine/musl hosts named for update), GPUStack CVE-2026-102895 (unauthenticated admin access and secret disclosure), SignalWire FreeSwitch CVE-2026-116779 (code injection), and IBM Aspera Faspex CVE-2026-123218 (authenticated privilege escalation). The brief states GreyNoise observed a first confirmed successful exploitation of the OpenSSH flaw on Nov 7, but the CISA entries themselves print no exploitation details. Hunters should prioritize patch verification and review of OpenSSH authentication logs and GPUStack API activity.

Why P1: Actively exploited, KEV-listed internet-facing components with a stated exploitation observation for OpenSSH; no concrete huntable behaviors printed in the sources provided. · ATT&CK: T1190, T1078

P1 · Plex2Shell (CVE-2026-96652 et al.) exploitation reported against Plex Media Server on QNAP NAS devices — update to 2026-11-09's story

QNAP warns that threat actors are exploiting Plex2Shell, a four-flaw chain in Plex Media Server, to compromise QNAP NAS devices; exploitation reportedly began in mid-October after PoC code was published, and QNAP says some users report their Plex servers appear compromised. Exploitation requires no valid credentials and grants code execution with the privileges of the Plex service, and QNAP's OS itself is not affected. Hunters should review internet-exposed Plex Media Server instances on QNAP for unexpected code execution by the Plex process, and remediate by updating to Plex Media Server 1.43.3 or later and rotating Plex and NAS passwords.

Why P1: Actively exploited internet-facing media server software on widely deployed NAS devices with public PoC; no credentials needed. · ATT&CK: T1190

P2 · Hijacked Ethersphere release automation pushes malicious bee-js 13.3.0 and Swarm Desktop 0.56.2 wallet stealer/backdoor

Attackers using stolen CI credentials (bee-worker account) published bee-js 13.3.0 to npm and Swarm Desktop 0.56.2 via the project's signed build workflows. A loader fetches code from api.frameworkmetrics[.]xyz that exfiltrates config.yaml and swarm.key, installs a Go remote shell (evjawbreaker) on Linux/macOS under ~/.solidity with systemd/LaunchAgent persistence, and on Windows uses a UAC bypass, adds a Defender exclusion and installs a ScreenConnect client. No infection count or fund theft reported; hunt for npm postinstall network calls, ~/.solidity, the persistence units, and unexpected ScreenConnect services.

Why P2: Supply-chain compromise with concrete huntable persistence/behaviors, but niche package with ~10 npm downloads. · ATT&CK: T1195.002, T1059.007, T1105, T1552.001, T1041, T1543.002, T1543.001, T1543.003, T1548.002, T1219, T1102, T1078, T1071.001

P2 · Turla attempts espionage with Cereal malware injected into Exchange EdgeTransport.exe at government organizations

Russian state-linked group Turla deployed a modular .NET toolset called Cereal against government Exchange servers, documented by ESET in Kazakhstan and Romania. CerealBox injects into EdgeTransport.exe to hijack transport agent handlers and harvest selected email, while CerealNeuron receives encrypted web requests on Exchange-like paths and executes CerealRunner programs. ESET observed no external C2, so the compromised Exchange server served as the control point; hunters should look for unusual code in EdgeTransport.exe, encrypted web requests to Exchange-like paths, and the CerealRunner/CerealNeuron artifacts listed in ESET's GitHub IoCs.

Why P2: Concrete huntable behaviors in Exchange, but targeting is government-focused and no CVE or mass exploitation is stated. · ATT&CK: T1505.003, T1055, T1114, T1071.001, T1027, T1003, T1087, T1595

P2 · SAP November patch day fixes four unauthenticated CVSS 10.0 flaws in NetWeaver ICM, Web Dispatcher, Gateway and SAML2; no confirmed exploitation

SAP's November 2026 Security Patch Day fixed four flaws rated CVSS 10.0 that can be exploited without authentication, affecting the ICM, Web Dispatcher, Gateway and the SAML2 service provider in NetWeaver AS ABAP. Onapsis reports that the ICM and Web Dispatcher flaws (CVE-2026-76964 and CVE-2026-89126) stem from one WebSocket split-message bug it calls ICM2SHELL, with a working exploit running OS commands as <sid>adm, and that the Gateway flaw (CVE-2026-89103, PROXYGATE) can be abused through a permissive proxy list. The sources state that none of the flaws has been seen exploited in attacks. Hunters should review Web Dispatcher and gateway proxy configuration and look for SAML logons by privileged users from unexpected sources.

P2 · Attackers probing SAP NetWeaver honeypots for webshells left by CVE-2025-31324; no confirmed compromises stated

SANS ISC observed a campaign against SAP NetWeaver in honeypot data, with requests for /irj/servlet_jsp/irj/root/ant.jsp and many other upload and webshell paths from a single source, 82.26.72.21. The diary says the campaign exploits or searches for webshells left by CVE-2025-31324, an unauthenticated file upload flaw the diary describes as CVSS 10, and that webshells usually end up under /irj/servlet_jsp/irj/root/. Hunters should look for requests to ant.jsp or upload paths on SAP web servers and for unexpected files in that webroot; the source does not confirm any successful compromise.

Why P2: Probing for webshells on a known exploited SAP flaw with concrete request paths, but the source reports only scanning and no confirmed compromise. · ATT&CK: T1190, T1505.003
