SlowMist logs Bitget attacker activity from 31 August, Mandiant dates access to 24 September, neither names a product

Two forensic documents published on 30 September add a longer chain, two products, a web shell and a custom withdrawal tool. SlowMist's logs start on 31 August, Mandiant dates the appliance access to 24 September, and neither names a product, vendor or CVE.

Threat Intel30 Sept 2026

A new MikroTik RouterOS flaw is not the exploited one, and CISA changed its fix version from 7.23 to 7.24

CVE-2026-84411 is new, scored 9.8 and not reported exploited. CISA now names 7.24 as the fix, above the newest long-term build 7.23.7, and MikroTik has published no advisory.

Threat Intel30 Sept 2026

Cisco dates the SD-WAN Manager attacks only as 'September', and omits five trains its May table listed

CISA set a federal deadline of Saturday 3 October. What Cisco states and does not, the fix table set against its May one, four names for one flaw, what the UK record says, and a defender checklist.

Breaches and Incidents30 Sept 2026

Microsoft's Titan skipped the token signature check: 17.3 trillion rows counted, two sampled

Faav's write-up counts 17,333,335,124,315 rows from metadata and describes two one-row samples. The endpoint was locked down 4 days after the report, the bounty was $5,000, and Microsoft edited the only account.

Threat Intel30 Sept 2026

543,699 working credentials in public GitHub code: at least 63% predate default push protection

What the Truffle Security count establishes, what its dates probably mean, and the gap it names itself: GitHub can block some secrets at push time, but only the issuer can make a leaked key stop working.

Compliance and Regulation30 Sept 2026

808,000 UK businesses were not confident at one or more of nine tasks, and that measures confidence, not skill

The 57 per cent is a share of 1.42 million businesses with staff, mostly micro firms, counted if any one of nine tasks failed a confidence question. Only three of the nine tasks rose since the 2025 report.

AI Security30 Sept 2026

Glow found 13,000 public screenshots; GitHub's CLI gained image attach 8 days before Glow began notifying

Glow's PixelLeak count works out at about 38 images per organisation and says nothing about sensitivity, access or models. The CLI feature the agents lacked shipped on 1 September, 8 days before Glow began notifying.

Threat Intel30 Sept 2026

Nine of 13 Star Blizzard campaigns are event invitations, and the invitation usually has no attachment

A count of Microsoft's own timeline, an invitation with nothing to scan, and six labels that reassure without controlling anything: what the RedFlick report establishes about Star Blizzard, and what it leaves open.

Threat Intel30 Sept 2026

Spectre BTR: a Linux root hash in 3 to 5 minutes on two Intel chips, with the kernel fix public since July

VUSec and Sant'Anna's Branch Target Reuse attack read a root hash at 8 bytes per second on two Intel chips. Stale predictor entries were reusable on AMD and Arm too, but nothing leaked there. The kernel fix dates from July.

Threat Intel30 Sept 2026

Citrix NetScaler was exploited at least 22 days before the patch. The three-day federal clock ends today

Mandiant, eSentire and GreyNoise now date NetScaler exploitation to before the 27 September bulletin. What Mandiant observed and what it did not, how the exploited pair compares with briefing 143, and what to hunt and harden.

Breaches and Incidents30 Sept 2026

France's tax authority learned of the theft 49 days after it began, from the thief's own claim

The French tax administration took 49 days to learn of a theft made with stolen staff passwords, and only from the attacker's own post. What the ANSSI report establishes, what it leaves out, and the checks a UK team can run.

Threat Intel30 Sept 2026

OpenSSL's DTLS leak is scored 8.2 by CISA and 7.4 by Red Hat, and the gap is what OpenSSL did not say

A DTLS retransmission bug can send OpenSSL heap memory to the other side or crash the process. Fixes are public for four branches, premium-only for three and absent for 3.1 to 3.3. No exploitation is reported and no leak size is stated.

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.

Market and Supply Chain29 Sept 2026

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.

Compliance and Regulation29 Sept 2026

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.
