Threat Intel28 Sept 2026

852 of 1,235 Meta ads led to 17 toll fraud apps, and Google's takedown did not stop the billing server

A store takedown is a distribution control, not remediation. CERT Polska's toll fraud analysis shows the billing server outliving the Google Play removal, and why a UK premium rate bar may not cover the route this operation used.

AI Security28 Sept 2026

Sonnet 5.5 beats Opus 5.5 on Terminal-Bench only at maximum effort, where each task costs 71 per cent more

Sonnet 5.5 is a large, well-documented step up from Sonnet 5 at the same price. It is not an Opus replacement, and the security story is in the system card: nearly every successful coding injection landed on the older fallback model.

AI Security28 Sept 2026

Seventeen hours of looking, seven minutes of deleting. The SQL databases survived because the attacker used the wrong API version

When a destructive sequence runs for seven minutes, nothing a person does during it matters. Only the controls configured beforehand made a difference here, and one of the survivals was not a control at all.

Threat Intel28 Sept 2026

The WAF rule blocked one spelling of the path. ShinyHunters used another, 107 days after Oracle's patch

A rule that matches the text of a path is a control on one spelling of an endpoint, not on the endpoint. The attackers read the published guidance and aimed at the organisations that followed half of it.

Threat Intel28 Sept 2026

Citrix fixed eight NetScaler flaws in one bulletin. The three-day federal clock covers two, and neither is the highest scored on NVD's scale

KEV is a list of what is exploited, not a ranking of what is worst, and a three-day deadline makes it very easy to forget that. The Citrix bulletin of 27 September is a clean example of the difference.

Threat Intel28 Sept 2026

CISA's weekly vulnerability bulletin ends today. The largest section of the final edition has no severity at all

CISA is not retiring the bulletin because it failed. It is retiring a faithful record of a model that stopped working, and the final edition shows exactly where it stopped.

28 Sept 2026

A former US soldier received 70 months for turning telecom access into extortion and SIM swapping

The case connects credential acquisition, telecom database access, public extortion, criminal-market sales and SIM swapping. Each stage left a different defensive opportunity.

28 Sept 2026

ChatGPT now shows its security history. The event log is evidence, not a verdict

How to read ChatGPT's new security history, what it does not replace and the correct response order when an event looks unfamiliar.

28 Sept 2026

Wireshark fixed 18 vulnerabilities in one release and credits the volume to AI-assisted reports

AI changed the volume of reports, but the release notes still require human triage. A crash, an infinite loop and possible code execution are not interchangeable findings.

28 Sept 2026

Google is putting a TPU in orbit next week. That is still a long way from a space data centre

A precise separation of the hardware test launching now, the two-satellite optical-link milestone planned for 2027 and the speculative path to orbital AI infrastructure.

28 Sept 2026

Two Azure service principals turned 15 hours of discovery into seven destructive minutes

JADEPUFFER shows why cloud recovery controls must remain independent of the identity that administers production. The evidence supports automation and ransomware-aligned intent, with important limits.

28 Sept 2026

Citrix has two exploited NetScaler RCE flaws. One needs no feature to be enabled

Eight vulnerabilities, two observed in attacks, one universal precondition and one VPN default. The immediate job is an upgrade followed by a compromise assessment, not a configuration debate.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.
