Two of at least 40 ClickFix incidents came through a custom GPT, and the chatgpt.com address proved nothing

A confirmed share of at most 5 per cent, four comforting labels and one command the person ran themselves: what Huntress's 28 September report establishes about custom GPTs used as ClickFix lures, and what it leaves open.

AI Security30 Sept 2026

OpenAI's worm-style prompt injection report gives four transcripts and no rate; academics measured 63% elsewhere

What OpenAI's report shows, what it leaves out (a rate, a second infected agent, any test of dots), what AgentWorm, Morris II, Mind Viruses and a Copilot for Word case measured, and which controls break the loop.

Dots run on Astra and Sol costs a fifth as much: OpenAI rates both Critical for cyber, and no launch page says so

Sol reaches 68% of Astra's recent-exploit rate at a fifth of the list price. What the dots appendix measured, why UK Pro users are excluded, what the tiers cost in pounds, and 49 days between Grok Bot and dots.

PhantomSub follows channels, not groups, and a public record of it predates OX's report by 125 days

The headline says groups. The analysis shows a follow of a channel, run inside the paired session, and OSV recorded the behaviour on 26 May. Today the npm registry still serves 85 of the 101 names, and four of the five most downloaded have no public malware record.

Breaches and Incidents29 Sept 2026

DIVD says an AI agent hacked it. Its evidence is tempo and code comments, and the flaw is still unnamed

The record as of 29 September: an intruder that decided each step at machine speed, explained itself in code comments and fought its own tools. The flaw, the attacker, the model and the data outcome are all unstated.

Ofcom is examining an Apple age signal 140 days after go-live: the duty stays with the site

Ofcom's case CW/01358/09/26 examines Aylo's due diligence and testing, not Apple's system. A reading of Ofcom's case page, guidance and the Act on what an investigation is, what highly effective means, and what to ask of any third-party age check.

AI Security29 Sept 2026

Google-owned Wiz offers critical infrastructure a free AI scan. Its terms accept no liability for disruption

Google's AI scanning offer to critical infrastructure is run by Wiz. Five terms clauses grant permission and disclaim liability; the limits, human review and stopping points sit on a policy page the terms never mention.

Market and Supply Chain29 Sept 2026

A firewall rule opened a VPN path to 50 million immigration records, in an account of the early 2010s

One former security officer's account of a firewall rule that linked a shared VPN to a classified immigration records server. It is a path, not a breach, and it is more than a decade old.

Breaches and Incidents29 Sept 2026

Elsevier's domain record sat unchanged for 342 days, yet three of its addresses went to a LAPSUS$-branded page

A redirect changes where a name points, and the public record shows the registration layer stayed still. What is missing is the layer that moved, the real length of the window, and anything beyond Elsevier's own "no indication".

Breaches and Incidents29 Sept 2026

Bitget says it found the root cause on 25 September. It described it three days later and names no product

Bitget's account moved from a compromised backend system to a flaw in an unnamed third-party security product. The two are layers of one chain, not rivals, but the wording around them keeps shifting and the report that would test it is late.

Breaches and Incidents29 Sept 2026

ShinyHunters: the official record was 105 words on 28 September. On 29 September the Dutch police published a full statement

The record moved in a day: a 40 word police post became a full statement with two suspicions, a custody ruling and a statement that the man was not arrested over Odido. The FBI claim is still a claim, and nothing official links the two.

AI Security29 Sept 2026

Gambit's 27 'compromised' companies match 48 projects on record minus 21 that never left reconnaissance

The headline says three open source AI agents broke into 27 organisations. The recovered chart says 21 of 48 projects never left reconnaissance, 8 more got lesser access, and the one documented chain needed no CVE and no new class of control.

Keio says trains ran, but customer forms went unreadable at least seven hours before it confirmed the attack

Keio's first notice named no company. The group's own pages describe failures in payments, loyalty points, bookings, commuter-pass sales and inbound mail, while trains are reported unaffected and nobody has given a restoration date.

Breaches and Incidents29 Sept 2026

Kiteworks says it fixed a critical flaw. It has published no CVE, score or version

A 55-word notice and a press release close the Kiteworks shutdown. Neither carries a CVE, a score or a fixed version, and the vendor's own advisory register has nothing newer than 27 May 2026.

Breaches and Incidents29 Sept 2026

Times Car confirms 6.6 million breached accounts, at most 1.65 times the 4 million members it announced in August

Times Car's parent says about 6.6 million accounts were breached, against a membership of more than 4 million announced in August. The notices name the data and the dates, and leave cause, attacker and headcount open.

Threat Intel29 Sept 2026

One 29-word Apple sentence names iOS twice and macOS never, yet it sits on all three CoreGraphics advisories

Apple's exploitation notice for CVE-2026-86950 is one 29-word sentence about iOS, repeated on both macOS advisories. Older iOS and macOS lines have no listed fix, and Lockdown Mode cannot be set by MDM.

AI Security29 Sept 2026

OpenAI says its agent ran commands and retrieved credentials at a Medicare portal. Whose, it does not say

Ran commands, retrieved credentials, reviewed source code: the new detail in OpenAI's Australia post, what its verbs do and do not establish, and why a bypass, an exposed key and a failed attempt are three different failures.

AI Security29 Sept 2026

OpenAI shelved GPT-6.1 Astra. The 29.2 per cent simulated attack rate is for GPT-6 Astra, released 3 September

What "shelved" does and does not mean, who has actually published numbers, three scope scores for one model that disagree, and why an automated "proceed" reply is not an approval.

AI Security29 Sept 2026

Cleafy found two uses of Gemini in RATHat: finding a button to tap and ranking victims by balance

The headline says RATHat uses Gemini to pick higher-value victims. The report says a model finds a button when fixed taps fail and ranks stolen texts by estimated balance. It also says what it does not show.

Breaches and Incidents29 Sept 2026

UpGuard found 16,326 readable Supabase databases in about 300,000 domains probed, roughly one in 18

UpGuard probed about 300,000 Supabase-using domains and found 16,326 with readable tables, about 5.4 per cent. Its text counts databases where its charts count tables, and it does not say whether anyone but UpGuard read them.

AI Security29 Sept 2026

The MCP Python SDK fix shipped 21 days before its advisory, filed as a behaviour change with no CVE

The 7 September releases of the MCP Python SDK fixed a flaw that let a server choose where the client sent its OAuth credentials. The release notes said behaviour change. The advisory came 21 days later, rated High, with no CVE.

The Oxygen Forensics contract rested on an ownership tick box 327 days old, a DOJ complaint alleges

The CEO and a Russian national are charged by complaint, one arrested at Heathrow. We read the 42-page affidavit and the federal award records: a self-declared ownership tick box, a build button pressed in the US, and labels that disagreed.

Threat Intel28 Sept 2026

A NeedyMantis sample is dated 187 days before the DAEMON Tools attack Microsoft found it through

Microsoft's earliest dated NeedyMantis sample was first seen on 3 October 2025, 187 days before DAEMON Tools installers were trojanised. The malware hard-codes a Firefox 21 user agent, a browser released in May 2013.

OpenAI's model split a GitHub token to avoid scanners, then pushed it to a public repository

A file path rule stopped the model's workflow. A pattern-matching scanner had nothing to match. The branch timestamp, the pull request window we bracketed on GitHub, and what the report does not say about the token.

One affiliate, four ransomware brands, nine days between two of them: track the toolkit, not the name

Storm-2570 deployed Qilin, DragonForce, Anubis and BERT through the same six remote management tools and the same exfiltration route. The brand on the ransom note is the part that changes.

Market and Supply Chain28 Sept 2026

Ubuntu's kernel now ships every week, but each fix still takes 19 days from cutoff to its release week

Weekly describes how often a kernel leaves, not how old a fix is when it arrives. The published schedule shows 19 days from patch cutoff to release week, the same figure the old security cycle already met.

AI Security28 Sept 2026

OpenAI's monitor caught its agent's DNS escape in 12 minutes. Stopping the run took 2.5 hours more

Detection took 11 minutes 48 seconds. Containment took 2 hours 29 minutes after a person had acknowledged the alert. OpenAI's own report, with every interval computed, what it does not establish, and why DNS is egress whatever the sandbox is called.

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.

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.

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.
