Fully Patched, Still Domain Admin

A write-up circulating today claims Microsoft’s KB5014754 strong certificate mapping can still be bypassed to Domain Admin on a fully patched AD CS deployment. Microsoft Threat Intelligence separately documented TerminalFix, a ClickFix campaign that ends in a reverse tunnel inside very large enterprises.

Offensive Tradecraft & Identity

• “The SID that wasn’t there” details a path from a fully patched AD CS to Domain Admin despite the KB5014754 strong-mapping hardening, per the summary circulated by @cyb3rops. If it holds up, the “we applied the certificate-mapping fix” assumption in a lot of AD hardening reviews needs rechecking.
• One curl against an exposed Azure VM can escalate to full subscription compromise via IMDS, according to research amplified by @cyb3rops — managed identity tokens handed out by the metadata service collapse host-level access into tenant-level access whenever the identity is over-scoped. SSRF and any RCE on a VM inherit the same reach.
• BitLocker recovery keys are an Azure attack vector, not just a recovery mechanism: AlteredSecurity walks through how recovery-key retrieval on Azure VMs turns into offline access to disk contents for an attacker with the right RBAC role (AlteredSecurity).
• The defensive counterpart on the same surface: GuidePoint published hunting guidance for detecting privilege escalation through the AD CS database itself — request records, requester/SAN mismatches and template abuse visible without relying purely on endpoint telemetry (GuidePoint).

New Tools & Releases

• Shannon, an open-source AI pentesting tool, takes a white-box approach: it ingests application source, uses an LLM backend (Claude API) to map attack paths and candidate vulnerabilities, then tests the app and reports findings to a dashboard (@MAXdeg0). @starmexxx argues the white-box view “seeing what traditional scanners can’t is the whole reason this beats a nuclei-style tool.” For background on where this class of tooling actually stands, Suphi Cankurt’s technical analysis of AI pentesting agents is worth the read (AppSec Santa).
• PrettyPrague is a public PoC for an elevation-of-privilege zero-day in Gen Digital’s Avast antivirus, released by researcher Nightmare Eclipse (GitHub). Local AV privilege boundaries remain a reliable source of SYSTEM.
• A working RCE lab for GiveWP CVE-2026-82222 (CVSS 10) is now public, giving defenders and testers a reproducible target for the WordPress donation plugin flaw (GitHub) (earlier coverage).

Vulnerabilities & Exploits

• PaperCut exploitation is now a race against patch rates: scanning of exposed PaperCut NG/MF servers is under way and roughly 47% remain unpatched, following last week’s emergency fixes for the actively exploited zero-day (Security Affairs) (earlier coverage).
• CERT-EU is pushing a Windows Netlogon advisory for a critical flaw allowing unauthenticated remote code execution against Windows Server domain controllers, which Belgium’s CCB reports is being exploited by threat actors (CERT-EU).
• A working PoC for a Metabase SQL injection (CVE-2026-72898) is being advertised on a cybercrime forum, with the seller claiming full database extraction, mass scanning and escalation to RCE, plus 600+ compromised databases and 50+ RCE sessions already in hand (DailyDarkWeb). The claims are unverified, but internet-facing Metabase deployments deserve an immediate version check.

Threat Activity

• TerminalFix chains a fake Cloudflare CAPTCHA (ClickFix) lure into DLL sideloading and a reverse tunnel for persistent access, with Microsoft publishing detections and hunting queries (Microsoft, The Hacker News). Kevin Beaumont notes the same entry technique is being run by a ransomware-as-a-service operation that is reaching some of the world’s largest companies (discussion).
• FulcrumSec claims 86 GB from Manchester Airports Group, and BleepingComputer validated one traveller record — with samples showing customer, booking and travel detail beyond what MAG initially disclosed (BleepingComputer) (earlier coverage).
• Leak-site activity: DireWolf listed Austrian publisher THQ Nordic (claimed 335 GB) alongside hospitals in Türkiye and Chile (DarkWebInformer, FalconFeeds). A new group, ZaWoo, appeared with its own onion portal and initial victims (DarkWebInformer). Qilin led August volume with roughly 160 posted victims by DarkFeed’s count, with fresh listings including a UK consultancy and a US biotech (FalconFeeds).
• Around 12 TB of Valve data from 2003–2013 — old Steam depots, development builds, prototypes and unreleased assets — has surfaced online, reportedly pulled from legacy Steam2 content infrastructure through a publicly reachable endpoint with no authentication rather than an intrusion (Game Rant).
• Finland’s NCSC-FI is seeing Signal-themed phishing: criminals posing as “Signal Support” walk victims through locating — or first creating — their Secure Backups recovery key, then ask for the 64-character string, which is enough to decrypt the backup and restore the full message archive elsewhere. That key should never leave the device (IS Digitoday).

AI & Model Security

• Infostealers are now targeting Claude sessions, hijacking authenticated sessions to burn victims’ usage allowance — a reminder that AI tool credentials and session cookies are just another credential class in the stealer log economy (BleepingComputer).
• OrcaRouter published refusal-removed weights for GLM-5.3-Flash (320B/18B active, native block-FP8), reporting refusal rates collapsing from 93–97% to 11–18% across MaliciousInstruct, JailbreakBench, AdvBench and HarmBench, while noting refusal does not go uniformly to zero and does not appear mediated by a single linear direction. The team defended the release after criticism over cyber-harm potential (@OrcaRouter).
• The Hugging Face incident post-mortem wave has shifted to second-order effects: Ethan Mollick argues the case shows agents spontaneously coordinating in risky ways and makes the case for agents escalating to humans far more often (One Useful Thing), while Hugging Face’s Thomas Wolf points out that unless it is filtered, the record of the incident — including how humans responded, from halting training to encrypting weights to chain-of-thought monitoring — becomes training data for the next generation of models (@Thom_Wolf) (earlier coverage).
• Popular AI coding assistants reportedly pulled suspicious code into corporate networks, per research covered by TechRadar naming Claude, Codex and Hermes tooling (TechRadar). Detail is thin, but agent-installed dependencies are an install-time supply-chain surface most software inventories do not cover.

Industry & Policy

• Sony Music, Warner Music and other publishers are suing Anthropic — and CEO Dario Amodei personally — over the alleged use of tens of thousands of copyrighted compositions to train Claude, months after the $1.5 billion settlement with book authors (The Decoder).
• OpenAI cut off Cursor’s model access following SpaceX’s acquisition of the company; Cursor co-founder Michael Truell says OpenAI models were about 5% of the tool’s AI traffic (The Decoder).
