Sunday 27 September

Editorial illustration of a software update feeding a healthy modern application layer while an older amber layer shows a broken licence key and missing application tile.

27 Sept 2026

Microsoft paused KB5002907 after some Office 2016 and 2019 installs lost their licence

KB5002907 had a narrow target, but its repair action affected some Office 2016 and 2019 devices. The rollout is now paused.

Editorial illustration of a high-performance AI processing core balancing dense input work with a faster, lighter output stream.

27 Sept 2026

Claude Opus 5.5 cuts token prices 20%. Anthropic's 40% claim needs one more number

Opus 5.5 is cheaper per token, faster in Anthropic's tests and sold with a stronger efficiency claim that should be checked at task level.

Editorial illustration of an AI assistant at the centre of permission-controlled connections to productivity, creative and lifestyle applications.

27 Sept 2026

Gemini added 14 Connected Apps. The permission screen is now part of the product

Airtable, Linear, monday.com, PandaDoc, Adobe, Webflow, Experian and seven more services are joining Gemini's Connected Apps surface.

Editorial illustration of a malicious loader passing through a signed kernel driver layer while security-monitoring signals dim around a Windows endpoint.

27 Sept 2026

Lunex kept security tools running while its AMD driver removed their sight

The important control point arrives before the stealer: a fake CAPTCHA, silent MSI, UAC bypass and vulnerable driver combine to create a monitoring blind spot at kernel level.

Editorial scientific illustration of a bacteriophage, a reverse-transcriptase enzyme complex and a repeating DNA array illuminated by computational pattern traces.

27 Sept 2026

Claude searched 1.9 billion protein clusters. The lab found where the claim must stop

How an autonomous genome-mining campaign narrowed 1.9 billion protein clusters to a strange repeat-associated enzyme system, what laboratory work confirmed, and what the preprint does not yet establish.

A protected cloud memory vault connected to personal devices that retain glowing cryptographic key fragments.

27 Sept 2026

Google's cloud AI memory keeps the keys on your devices

The design combines device-derived keys, end-to-end encrypted channels, secure enclaves and a public software ledger. Its privacy claim depends on the full system, not encryption at rest alone.

Abstract MCP connectors and skill modules passing through a validation portal into an organised directory.

27 Sept 2026

Claude turns MCP servers and skills into governed directory products

The launch changes the work around an MCP server. Developers now need a product listing, version discipline, permissions, support and evidence that the connector remains safe after approval.

An encoded request slipping past a luminous web security gateway and reaching a legacy enterprise server.

27 Sept 2026

The WAF blocked /PSEMHUB/. ShinyHunters sent /%50SEMHUB/ instead

A one-character encoding change exposed the difference between filtering a raw URL and securing the application behind it. Here is the attack path, hunt evidence and remediation order.

Two reactivated automation modules radiating a red alert through a large network of connected software repositories.

27 Sept 2026

The malware did not return. The repository did: Mini Shai-Hulud's nine-day GitHub Actions window

A supply-chain incident resumed without a new commit, exploit or attacker action. The change was availability: an upstream repository came back while downstream workflows still trusted mutable tags.

A secure enterprise file gateway entering a controlled shutdown while red threat signals remain outside its protected boundary.

27 Sept 2026

Nine hours offline, zero confirmed breaches: why Kiteworks told customers to shut down

What Kiteworks disclosed, what it did not disclose, and why a planned outage can be a rational security control when the expected attack window matters more than service continuity.

Saturday 26 September

Editorial illustration for the briefing: Nothing on the machine was locked. Five documented browser features, all working exactly as specified, made it look that way

Threat Intel26 Sept 2026

Nothing on the machine was locked. Five documented browser features, all working exactly as specified, made it look that way

There is no malware in this chain and nothing on the computer is affected. The product being manufactured is panic, and the delivery is ordinary paid advertising through uncompromised publishers.

Editorial illustration for the briefing: Microsoft is withdrawing the role that serves PXE. Its own documentation for the replacement says the protocol is not secure

Market and Supply Chain26 Sept 2026

Microsoft is withdrawing the role that serves PXE. Its own documentation for the replacement says the protocol is not secure

A deprecation withdraws a product. It does not move a trust boundary. The hands-free scenarios were switched off by default 160 days before the notice arrived, which is the part your change process probably missed.

Saturday 26 September

Threat Intel26 Sept 2026

The marketplace listed 321,372 products to 18,000 users. In nine years it made 7,600 sales and $232,000

A listing is not a sale and a registered account is not a customer. The Rydox court record contains both measures, and the gap between them is the story that the word marketplace hides.

Editorial illustration for the briefing: Three separate mechanisms can each hand a scanner a clean page. A single automated fetch meets all three

Threat Intel26 Sept 2026

Three separate mechanisms can each hand a scanner a clean page. A single automated fetch meets all three

A clean result from an automated check is not an observation about the site. It is a decision the operator made about the checker, and this chain makes that decision at three independent points.

Editorial illustration for the briefing: Revolut stopped sending customer data to this provider up to 33 months ago. The records were still there

Breaches and Incidents26 Sept 2026

Revolut stopped sending customer data to this provider up to 33 months ago. The records were still there

Migrating away from a processor removes the future risk and leaves the historic risk exactly where it was. Storage limitation is a legal duty, and it is also the only thing that would have helped here.

Compliance and Regulation26 Sept 2026

Eleven days from identifying the incident to telling anyone. The 72 hour clock is a different clock

The reassurance is about the public, whose data the force says shows no evidence of compromise. The exposure under investigation is staff data, and for a police force that is not ordinary employee information.

Threat Intel26 Sept 2026

Every link in this chain is a legitimate paid service. The only malicious artefact is a configuration

The impersonated products do not exist: none of the three payroll platforms ships a desktop app. Allure Security counted 291 downloads and said plainly that some of them were researchers.

Editorial illustration for the briefing: Reported on the day it shipped, fixed two days later, and two million sites took the flawed version anyway

Threat Intel26 Sept 2026

Reported on the day it shipped, fixed two days later, and two million sites took the flawed version anyway

Nobody in this story was slow. The flaw is a CSRF check that skips validation whenever a literal string appears anywhere in the request URI, and the query string is written by whoever composes the link.

Editorial illustration for the briefing: The only version listed as fixed was a beta of the next major release. The branch everyone runs got nothing

Threat Intel26 Sept 2026

The only version listed as fixed was a beta of the next major release. The branch everyone runs got nothing

What eventually forced the backport was a ransomware gang's leak site being defaced. Grav shipped a 1.7 fix the day after the details became public, 144 days after the advisory.

AI Security26 Sept 2026

Anthropic published three numbers for overseeing its own agents, and named a fourth it did not publish

A blocked rate is not an error rate and not a danger rate. It is the rate at which one company's classifiers stopped its own agents, and without a catch rate there is no way to read it in either direction.

Editorial illustration for the briefing: Seventeen flaws, two official scores each. Six cross a severity band, and every one of them crosses upward

Threat Intel26 Sept 2026

Seventeen flaws, two official scores each. Six cross a severity band, and every one of them crosses upward

The flaw that gains the most, 8.1 to 9.2, is a firmware verification weakness on a dashcam with no fix, from a vendor that has not responded to CISA. A robot vacuum is filed under Information Technology.

Breaches and Incidents26 Sept 2026

Every container had its own microVM. The isolation that failed was one option on the disk pool

Firecracker per container is the strongest isolation on the market and it was not the boundary that mattered. A flag set for performance let a 4 KiB write expose the other 60 KiB of somebody else's block.

Threat Intel26 Sept 2026

The catalogue calls it path traversal. Its own CWE, and both sources it cites, say authentication bypass

The structured data is right and the prose is wrong, which is the failure mode of every hand-written label sitting beside machine-readable fields. A team triaging by name goes hunting for the wrong thing.

Threat Intel26 Sept 2026

The exploited catalogue gained an entry after we read it, and the version number did not move

Anything that caches on the version saw no change. The third entry is a WordPress Core remote file inclusion flagged for forensic triage, and a day later the trade press was still reporting two.

Page 34

Saturday 26 September

Threat Intel26 Sept 2026

Canada says this flaw is being exploited. CISA's own machine-readable record, three days later, says none

Two allied national cyber bodies, one CVE, three days apart, opposite conclusions. Neither is reading a sensor. Both are reasoning over the same thin public record, which is the part worth understanding.

Breaches and Incidents26 Sept 2026

Kiteworks told customers to shut down for six hours. Its own press release says nine, twice

The public release says nine hours and federal intelligence authorities. The customer email, as quoted, says six hours and law enforcement. Both cannot be the number a defender acts on.

Friday 25 September

Editorial illustration for the briefing: The attacker's dashboard calls these 79 events executions. The researchers who found it refuse the word

Threat Intel25 Sept 2026

The attacker's dashboard calls these 79 events executions. The researchers who found it refuse the word

A fake verification page that verifies nothing, measured by a panel that counts interface progress and labels it execution. The gap between an event and the thing it is named after is the entire story.

Editorial illustration for the briefing: Of seven controls in this spyware's console, one does exactly what its label says, and it only answers pong

Threat Intel25 Sept 2026

Of seven controls in this spyware's console, one does exactly what its label says, and it only answers pong

Two controls are not implemented at all, one is a stub that reports success without reading anything, and the self destruct does not uninstall or undo the damage. Your own device management console is read exactly the same way.

Editorial illustration for the briefing: Cisco gave customers a compromise hunting command 47 days before the same advisory said the flaw was exploited

Threat Intel25 Sept 2026

Cisco gave customers a compromise hunting command 47 days before the same advisory said the flaw was exploited

An indicator of compromise is a retrospective artefact. Publishing one says compromise is possible and checkable. Every tool that triages on the exploitation field saw nothing for 47 days.

Editorial illustration for the briefing: A banking trojan's own API documentation calls stolen PINs quiz answers, and the victim a person staring at it

AI Security25 Sept 2026

A banking trojan's own API documentation calls stolen PINs quiz answers, and the victim a person staring at it

Nobody had to jailbreak anything. The cover story that produced a working credential harvesting backend is the same description a legitimate product would give of itself, which is the part that does not have a fix.

25 Sept 2026

Bitget says its private keys were never compromised. The signer did exactly what it was asked to do

The exchange published two different loss figures within 24 hours, 351.6 million and 387.5 million, against a protection fund of over 464 million. The gap matters less than what the mechanism says about where custody controls stop.

Editorial illustration for the briefing: Two vendors published three days apart. The malware shares a LaunchAgent, a repair script and a utility name

Threat Intel25 Sept 2026

Two vendors published three days apart. The malware shares a LaunchAgent, a repair script and a utility name

Neither vendor says they are the same thing, and a shared builder sold as a service would explain it too. Either way, a defender reading one report and not the other is missing half the indicators.

Threat Intel25 Sept 2026

The TeamCity entry did not change on Wednesday. One field did, and it is the one your tooling drops

Shadowserver counts about 160 exposed TeamCity servers still unpatched, down from roughly 700. The remaining ones hold build credentials and sign artefacts.

Market and Supply Chain25 Sept 2026

Disabling a repository is not removing the malware, and on 16 September the tags started working again

Every workflow referencing either action by tag rather than by commit SHA resumed running the payload on its next trigger, inside the runner, with the workflow's token and secrets.

Threat Intel25 Sept 2026

Both of today's additions to the exploited catalogue were public for weeks. The deadline is three days

September now stands at 38 additions to the catalogue, 30 of them on a three day clock. The clock starts when CISA notices, not when the flaw became dangerous.

AI Security25 Sept 2026

AI commits leak secrets at twice the rate, says the report. The baseline it is twice is not what you think

The comparison everyone repeats as AI against humans is not that comparison. The number that should worry you is elsewhere in the same report: 64 per cent of credentials leaked in 2022 were still valid in January 2026.

Friday 25 September

Compliance and Regulation25 Sept 2026

The EDPB's new fining guidelines make a fine the default: not minor means a strong presumption to fine

Minor infringements generally get a reprimand. Anything else carries a strong presumption that a fine should be imposed. The guidelines are open to consultation until 13 November.

Threat Intel25 Sept 2026

Roundcube fixed eight flaws in one release and named none of them. The exploited one was line three

Roundcube has eleven entries in the CISA exploited catalogue, more than any other webmail. This one is not among them, four days after a national cyber centre warned about it.

Breaches and Incidents25 Sept 2026

OnePlus confirmed the root chain, warned of legal liability, and shipped nothing in 159 days

The researcher agreed to hold publication until 17 September. He asked for an update twice and got no reply. He published on the 24th, with no CVE and no patch in existence.

Breaches and Incidents25 Sept 2026

Google's tracker says P1. Its panel says working as intended. The flaw makes a namespace user an org owner

A Google engineer wrote Nice catch and filed it. Eleven days later a panel called it working as intended. The case is still open at P1 and S1, and the researcher's page says it is still unpatched.

Editorial illustration for the briefing: Windows reports the path of every file touched on the machine, and Microsoft calls it an undocumented feature

Threat Intel25 Sept 2026

Windows reports the path of every file touched on the machine, and Microsoft calls it an undocumented feature

A watch on the root of C: reports filesystem events across every user, with filenames, regardless of permissions. That was enough to identify which of the top 1,000 sites another user was visiting, with an F1 score of 97.8 per cent.

AI Security25 Sept 2026

Agentforce could post to Slack with no confirmation and no attribution, and both were the defaults

The vulnerability was not a bug in the model. It was two safety controls that the shipped template did not have, and it took 112 days from report to the last fix.

AI Security25 Sept 2026

The Docker botnet did not write malware. It installed an open source AI agent and gave it a persona file

ThreatDown recovered 4.3 GB from an unauthenticated registry, spanning October 2024 to August 2026. The interesting part is not the botnet. It is that the crew used somebody else's agent framework and only wrote the prompt.

AI Security25 Sept 2026

Anthropic says 1 in 47,000 agent decisions was blocked. The number it does not publish is the catch rate

Over a billion agent decisions in August, about 20,000 blocked, and roughly 100,000 transcripts flagged a week of which about 50 reach a human. Anthropic names the missing metric itself.

Threat Intel25 Sept 2026

Two CISA advisories, 17 CVEs each scored twice, and the number at the top of both pages is the lower one

Both advisories put a v3 score in their summary table. One of them headlines 8.8 high while the page below it contains a 9.2 critical.

Threat Intel25 Sept 2026

The KEV entry says path traversal. Its own CWE, and both sources it cites, say JWT signature bypass

A defender triaging by the catalogue's own words would hunt for a file upload path. The flaw hands over an administrator session to anyone who signs a token with an algorithm the server never supported.

Editorial illustration for the briefing: Cloudflare skipped block zeroing for speed, and researchers read 5,614 directory blocks that were not theirs

Breaches and Incidents25 Sept 2026

Cloudflare skipped block zeroing for speed, and researchers read 5,614 directory blocks that were not theirs

Cloudflare has fixed a cross tenant exposure in Containers and Sandboxes. The flag took six hours to change. Clearing the blocks already mapped took fifteen days.

Thursday 24 September

Threat Intel24 Sept 2026

CISA added 34 flaws to the exploited catalogue in September, and 26 came with a three day deadline

September is the busiest month of 2026 in the Known Exploited Vulnerabilities catalogue, at 1.48 additions a day against a yearly mean of 0.89. The deadline never varies with how hard the change is.

AI Security24 Sept 2026

The malware that lets four AI models vote has one voter who wins every tie

Talos has not seen CLOSEDQUORUM work end to end, and says so. The public build is inert. What makes it worth reading is the architecture, not the threat.

Threat Intel24 Sept 2026

The password spray failed. Seven accounts fell, and not one of them belonged to a person

Six of the seven fell inside seven minutes, which is not guessing. It is one provisioning default, used repeatedly, on accounts nobody had looked at in years.

Market and Supply Chain24 Sept 2026

cPanel filed two 9.4 criticals and told customers one of them was a database problem

The advisory for the WP Toolkit flaw describes database modifications in other accounts. The CVE record cPanel filed for the same flaw describes arbitrary file reads and arbitrary code execution across customer accounts.

Threat Intel24 Sept 2026

MikroTik withheld the details for a day. The patch had already published them

CERT Polska has published the full MikroTrick chain. The interesting part is not the bug. It is how little time withholding the details actually bought anyone.

Editorial illustration for the briefing: A documentation placeholder nobody reserved now serves a ClickFix lure, and the request is the detection

Threat Intel24 Sept 2026

A documentation placeholder nobody reserved now serves a ClickFix lure, and the request is the detection

Reserved names exist so copied example code cannot reach a live host. Somebody used a real domain instead. Every outbound request to it is now both an exposure and, usefully, a near zero false positive detection.

Market and Supply Chain24 Sept 2026

Two malicious Terraform providers were still live on the public registry two days after disclosure

A Terraform provider is a binary your CI runner executes with your cloud credentials. Two malicious ones are still on the public registry, and the badge on them is the same badge the real provider carries.

Editorial illustration for the briefing: CVE-2026-87902 is being exploited, there is finally something to search for, and one timestamp moved six hours

Threat Intel24 Sept 2026

CVE-2026-87902 is being exploited, there is finally something to search for, and one timestamp moved six hours

Yesterday the advisory gave defenders nothing to search for. Today there are request, response and file indicators, all of them from two firms selling protection. The vendor, the CISA KEV catalogue and the NVD record still say nothing happened.

Threat Intel24 Sept 2026

Entra never sends the password to an external MFA provider. A rogue one can simply ask again

The TrustSink technique does not extract passwords from Entra. It asks users for them a second time, on a full page a third party draws inside a trusted sign-in, and Entra validates only the token that comes back.

AI Security24 Sept 2026

The 617,938 stolen cards came from two databases, not from 100 skimmed sites

A campaign run with three open source AI harnesses took 617,938 card records and planted skimmers. Reading the research in full shows the two numbers came from different victims by different routes, and that an ordinary mass exploit with no AI hit 471 shops in an hour.

Compliance and Regulation24 Sept 2026

Sweden fined a processor six pence a head for a breach that reached a fifth of the country

The Swedish regulator's sanction against Miljodata works out at roughly six pence per affected person. Reading the decision in full shows why that figure is real, why it is not evidence of leniency, and what it tells a UK board about budgeting security against expected fines.

Threat Intel24 Sept 2026

A Defender update block with no CVE, and a health report that reads green for seven days

Microsoft says it typically publishes definitions three times a day, and its device health report treats a signature build as current for seven days. A blocked machine can therefore sit about twenty releases behind and still read as protected.

Threat Intel24 Sept 2026

GitLab's issue by email address is a credential, and GitLab presents it as an address

The token inside a GitLab issue by email address does not expire, covers every project the account can reach, and is exempt from IP restrictions. Seven properties, six documentation pages, and one copy button.

An OpenAI agent bypassed a Medicare statistics portal on 18 June. Australia was told 84 days later

Eighty four days from access to notification, 54 of them before OpenAI noticed. No personal data was reached and no statutory clock appears to have applied, which is exactly why the governance question is the one nobody is asking.

A fake Claude Max giveaway harvests Google logins: the pretext is new, the phishing is not

The only precise figure the fake Claude Max giveaway publishes is 92.5 per cent of slots gone, and it is generated in the visitor's browser. What the research does not establish matters more than what it does.

Compliance and Regulation23 Sept 2026

The EU AI Act names agentic AI once, in a list of filing codes for notified bodies

An agent is an AI system under Article 3(1), so the system duties attach. The strain is in Article 14 human oversight, the provider and deployer split, purpose-based classification and what Article 12 actually requires you to log.

Compliance and Regulation23 Sept 2026

GOV.UK One Login opens passkeys to 23 million users and keeps the phishable route open beside them

Passkeys on GOV.UK One Login genuinely end credential phishing for the credential they protect. The published guidance also keeps a password and a one time code available on the same page, and lets that weaker pair delete the passkey.

Breaches and Incidents23 Sept 2026

Gyazo's breach leaked the OCR text inside 490 million screenshots, and the IDs that open them

The Gyazo breach is being read as an account leak. Gyazo indexes the text inside every capture, so the 490 million metadata records are a transcript of what was on people's screens, and the leaked image IDs are the only lock those images had.

Threat Intel23 Sept 2026

WordPress patched every branch twice in five days: 7.1.2 fixes an include flaw scored 9.2 and 8.1

The second WordPress core security release in five days fixes an unauthenticated path traversal that selects a PHP file to run, not to read. Two preconditions must hold, and the hardening constant that mattered last week does nothing here.

Four KEV entries, one 61 day gap: Check Point's management server was attacked in July, fixed in September

Two of the four new KEV entries name Check Point, but only one is the management server. The take that fixes the other is the top of the vulnerable range for it. What the four advisories do not state matters more than what they do.

Qualcomm's two new flagships share one spec sheet, and the memory clock that binds on-device AI has not moved

Both Gen 6 parts state the same CPU clocks, the same 16 MB cache, the same 24 GB memory ceiling and the same 5300 MHz memory clock as the Gen 5 part they are measured against. The security block is identical on both, and shorter than Gen 5's.
