Brotli decoder overflow (v1.0.3-1.2.0) in Node.js, .NET, Python, Go, Rust and most HTTP stacks. Exploitation is behavioral, so inventory every library.

PeopleSoft CVE-2026-35273 (CVSS 9.8): ShinyHunters (UNC6240) chained SSRF, file-path control and deserialization RCE from May 27; /%50SEMHUB/ bypasses WAFs. EBS CVE-2026-101767 (CVSS 9.8, 12.2.3-12.2.15): probed since Oct 27; Cl0p exploited EBS before.

TrendAI: 44 agents automate recon to exfiltration against Japanese government and financial targets (simplified Chinese on all three infrastructures). Unlike ARTEX's single agent, the AI conducts the attack.

1. Node2Shell / Brotli Exploitation (CVE-2026-111497):

What to monitor: - HTTP requests with Content-Encoding: br or Accept-Encoding: br to internal web services — baseline normal Brotli traffic volume and alert on anomalies - Node.js worker process crashes or unexpected restarts (Event ID correlation in application logs) - Unexpected outbound connections from Node.js or .NET worker processes to external IPs - WAF/proxy logs for unusually large or malformed Brotli-compressed payloads Detection rule logic: Alert when a web-facing Node.js or .NET process spawns a child shell process (cmd.exe, powershell.exe, /bin/sh, /bin/bash) — this should never happen in normal operation. ATT&CK: T1190 T1068

2. Oracle PeopleSoft Exploitation (CVE-2026-35273):

What to monitor: - HTTP requests to /PSIGW/HttpListeningConnector containing references to 127.0.0.1:8000/PSEMHUB/ - URL-encoded bypass attempts: /%50SEMHUB/, /%50%53EMHUB/, or similar encoding variations in web logs - New .jsp, .jspx, or .class files appearing in PeopleSoft web-accessible directories - Unexpected outbound connections from PeopleSoft application servers Investigation: If any PeopleSoft system was unpatched between May 27 and the date the June 2026 patch was applied, conduct a full web shell hunt. ShinyHunters' dwell time was at least 13 days in documented cases. ATT&CK: T1190 T1505.003

3. Oracle EBS Probing (CVE-2026-101767):

What to monitor: - Unauthenticated HTTP requests to Oracle EBS login and API endpoints containing SQL metacharacters (', --, UNION, SELECT, xp_cmdshell) - Database error messages returned in HTTP responses from EBS servers (information disclosure) - Unusual database query patterns or execution times on EBS backend databases ATT&CK: T1190

4. APT28 ScrambledPage Malware:

Blocking actions: Add the IOC-block hashes below to EDR blocklists and SIEM watchlists immediately. What to monitor: - Process injection events (Sysmon Event ID 8 — CreateRemoteThread, Event ID 10 — ProcessAccess with suspicious call stacks) - Unusual DLL loads in common system processes (svchost.exe, explorer.exe, rundll32.exe) - Outbound HTTPS connections from injected processes to unfamiliar infrastructure ATT&CK: T1204 T1055 T1105

5. Election Infrastructure Monitoring (Through November 3):

What to monitor: - Volumetric traffic anomalies against election-related web portals (voter lookup, results pages, e-filing) - DNS query spikes for election-related domains - New account creation or credential stuffing attempts against election management systems - Social media monitoring for coordinated disinformation campaigns referencing state election systems Defensive posture: Confirm DDoS mitigation services are active and tested. Ensure election night results pages have cached/static failover capability. ATT&CK: T1498 T1190 T1491

6. Microsoft Teams Social Engineering (STAC4749):

What to monitor: - Microsoft Teams external chat messages from unrecognized tenants, especially those referencing IT support, password resets, or MFA issues - Installation of unauthorized RMM tools (AnyDesk, TeamViewer, ScreenConnect, Atera) on endpoints - Chaos ransomware indicators: file encryption with random extensions, ransom notes in affected directories ATT&CK: T1566.003 T1219

Hunting Hypotheses:
HUNT 01
1. Node2Shell / Brotli Exploitation (CVE-2026-111497)
Attackers are sending crafted Brotli-compressed HTTP requests to Node.js and .NET web services to trigger buffer overflow and achieve remote code execution.
HUNT 02
2. Oracle PeopleSoft Exploitation (CVE-2026-35273)
Attackers are using SSRF through PSIGW to reach PSEMHUB and deploy web shells via deserialization.
HUNT 03
3. Oracle EBS Probing (CVE-2026-101767)
Attackers are probing Oracle EBS Application Object Library endpoints with SQL injection payloads.
HUNT 04
4. APT28 ScrambledPage Malware
APT28 delivers ScrambledPage via user execution (likely spearphishing attachment), then uses process injection to evade detection and establish C2.
HUNT 05
6. Microsoft Teams Social Engineering (STAC4749)
Attackers impersonate IT helpdesk via Teams external chat, then convince users to install RMM tools that deliver Chaos ransomware.

Patch Node.js, .NET, Brotli (1.0.10/1.1.1/1.2.1; Node.js Oct release) by Nov 10, else block Content-Encoding: br at the WAF; restart processes. Verify PeopleSoft CVE-2026-35273 (June patch): disable PSEMHUB if unpatched, else hunt web shells, rotate credentials. Add ScrambledPage hashes to EDR.
Incident ResponderSOC Analyst
Brief election officials on the FEC incident; confirm monitoring and tested DDoS mitigation. Activate election-week IR: 24/7 coverage, comms templates, CISA and MS-ISAC paths.
CISO / Exec

Apply Oracle October CPU (EBS CVE-2026-101767). Patch Veeam CVE-2026-108142, isolate CDP Coordinator, test restores. Restrict Teams external chat or add banners. Verify Fortinet firmware. Detect AI recon: rapid probing from rotating IPs, AI phishing.
Incident ResponderSOC Analyst
No 7-day actions for the selected roles.
Review PeopleSoft and EBS (WAF blocks /%50SEMHUB/, web shell hunts per tier). Inventory Brotli everywhere. Keep SBOMs under 72 hours old. Hunt Volt/Salt Typhoon on edge devices. Assess AI defenses (CyberStrikeAI).
