A Microsoft-signed driver kills 145 security tools, and Microsoft's own blocklist did not stop it

Alinubx.sys carries a 2023 Microsoft hardware signature, kills 145 AV and EDR processes, and was not on Microsoft's vulnerable driver blocklist at publication. What the blocklist, HVCI and the ASR rule do and do not cover.

WordPress fixed Comment2Shell in 25 releases on one day; check yours is one of them, and that no plugin arrived first

WordPress core shipped 25 security releases on 17 September for a comment XSS that can reach an administrator's session. What to confirm, which wp-config setting actually blocks plugin upload, and why updating does not remove a plugin already added.

Defender can report protected while its updates stall: how to prove signatures are current across an estate

BigDiskBuster, released on 19 to 20 September 2026, keeps Defender on whatever signatures it already has. Microsoft's own reports can call a device up to date for seven days. Here is how to measure currency, not status.

Only the Zyxel switch flaw is in CISA's KEV; the Veeam agent exploitation claim rests on one vendor headline

CVE-2026-7273 in Zyxel GS1900 switches entered KEV on 21 September with a 24 September deadline after GreyNoise documented data theft from 996 switches. CVE-2026-32996 in Veeam Agent for Windows has a public PoC but no KEV entry.

Talos's CLOSEDQUORUM lets four LLMs vote on an implant's next move, but the only public build is inert

CLOSEDQUORUM asks DeepSeek, Qwen, Mistral and Gemini which of four attack actions to take, then acts on the plurality. Talos found placeholder keys, no confirmed victims and a narrower first than the headline suggests.

A Windows privilege fix that held 28 days: Project Zero on dangling COM registrations

A COM class that points at a DLL that does not exist is not harmless. Project Zero shows how a dangling registration in a writable path becomes SYSTEM, and how to audit your estate for the same pattern.

Fake interviews target Rust maintainers' publishing rights, and arrayref showed what one stolen account does

Rust maintainers are being lured onto video calls to install a fake audio codec or paste a command. The arrayref release of 20 August, downloaded 2,285 times in 86 minutes, shows why their accounts are the prize.

Threat Intel21 Sept 2026

ChainScript's operator moved its C2 twice for a quarter of a cent, and the blockchain logged both moves

ChainScript turns a pasted Win+R command into a per-user MSI, a hidden Node.js agent and a C2 address stored on the Polygon blockchain. Here is the chain step by step, why the pointer survives takedown, and the controls that still work.

Threat Intel21 Sept 2026

North Korea's TraderTraitor put macOS backdoors on an Indian IT provider, and the delivery was never proven

The same two Jade Sleet backdoors that helped take 292 million dollars from KelpDAO turned up on an Indian IT provider with no crypto ties. What the vendor established, what it did not, and what UK firms that outsource to Indian MSPs should ask this week.

Threat Intel21 Sept 2026

Google's mole inside TeamPCP saw 500,000 stolen credentials and a gang that could barely cash them

TeamPCP stole more than 500,000 credentials but, by Google's estimate, made only tens of thousands of dollars. What an undercover analyst saw, what rests only on one researcher's account, and what UK engineering teams should change.

Threat Intel21 Sept 2026

TASK#STOMP: a PowerShell backdoor hiding in native Windows tools that already log it

TASK#STOMP relies almost entirely on wscript, PowerShell, Task Scheduler and the .NET compiler, so it leaves no conventional executable to catch. It also leaves a script block log, a task creation event and an AMSI scan behind at every step. The report does not name a victim, sector or attacker.

Threat Intel21 Sept 2026

PAYLOAD ransomware hit a whole Windows domain through two Group Policy objects and no endpoint malware

Two GPOs, six settings, no Windows malware: how PAYLOAD used Group Policy for domain-wide extortion, what Kaspersky could not establish, and the Microsoft audit events that would have seen it.

RatHat pairs with its own Android Debug Bridge. Uninstalling the APK can leave the shell behind

A step-by-step analysis of RatHat's Accessibility abuse, local ADB self-pairing, native persistence, credential theft and defensive controls.

Three SBOM tools scanned the same projects and disagreed. CRA compliance cannot be a generator checkbox

The new SBOM study quantifies tool disagreement and shows what manufacturers should validate before the Cyber Resilience Act applies in full.

Threat Intel20 Sept 2026

ShinyHunters defaced Clop’s leak site. The page proves write access, not stolen onion keys

The Clop defacement is confirmed at the presentation layer. The evidence does not yet establish server root, victim-data access or control of the onion identity.

Fake interviews exploited at least 30,000 PCs in eight months, and the wallets were the cheap part

A joint advisory of 18 September 2026 puts at least 30,000 exploited PCs and over 7,000 drained cryptocurrency wallets behind a fake recruitment campaign. The arithmetic says the access, not the crypto, was the product. No UK victim is named.

GitHub removed the fake LastPass repositories. Four of the six Rapuncel domains still resolve

Fake GitHub organisations impersonating LastPass Authenticator ranked in search and delivered an infostealer behind a Microsoft signed driver that terminates 145 security products. The repositories are gone. Most of the delivery chain is not.

A leaver's OAuth token copied about 170 CrowdSec private repositories, and the audit log never saw it

About 170 private CrowdSec repositories were cloned in nine minutes and four seconds on 22 May 2026, using the account of a developer who had just left. GitHub's own documentation explains why the organisation audit log was empty.

WordPress Click2Shell: the forced theme install still needs an administrator to open the link

The forced theme install is real, the chain to code execution is real, and both run on an administrator's session. Here is what WordPress fixed, in which versions, and what its own release notes do not say.

Threat Intel19 Sept 2026

CISA's three Linux kernel KEV entries and the four public root exploits are seven different flaws

Three Linux kernel CVEs entered CISA's KEV catalogue on 18 September 2026 and four others got public local root exploits the same day. No CVE appears on both lists, and the patch state differs sharply between them.

Threat Intel19 Sept 2026

Conductor's 9.8 was patched 27 days before it had a CVE, and CISA's exploited list still has no entry

CVE-2026-58138 lets anyone who can reach an unpatched Conductor server run operating system commands on it. The open-source build has no authentication to bypass, and the orchestrator holds credentials for everything it orchestrates.

WeaselBiscuit ran on import, not install, so ignore-scripts would not have stopped any of the 17 npm packages

WeaselBiscuit executed on import rather than install, so the standard ignore-scripts control sat at the wrong gate. Every package is now gone from npm, median takedown under 13 hours. Here is what it could actually reach.

Threat Intel18 Sept 2026

Unauthenticated root on a Check Point management server, triggered by an over-long username at login

CVE-2026-91843 lets an unauthenticated attacker run code as root on Check Point Security Management, Multi-Domain and Log Servers. The advisory names eleven affected version bands and offers four packages. No exploitation is reported and one indicator is published.

CISA ends its weekly vulnerability bulletin, a CVSS-sorted digest that never flagged exploitation

CISA retires its weekly Vulnerability Bulletin on 28 September. We parsed 70 issues: it was a CVSS-sorted copy of CVE records, with no exploitation signal, long gaps and a "Not Yet Assigned" table that hid CVSS 10.0 exploited flaws.
