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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
