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.

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.

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

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: 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.

Wednesday 23 September

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.

Tuesday 22 September

Breaches and Incidents22 Sept 2026

EvilTokens takedown: 226 domains in the court order, two arrests, and a phish MFA cannot stop

The court order lists 226 domains. Microsoft's own sworn declaration says device code theft cannot be stopped by multifactor authentication. What breaks the chain is a Conditional Access setting many tenants have never switched on.

Editorial illustration for the briefing: A stolen Ribon app key pulled BigCommerce shopper data in one evening, then stayed live almost four days

Breaches and Incidents22 Sept 2026

A stolen Ribon app key pulled BigCommerce shopper data in one evening, then stayed live almost four days

The Ribon breach on BigCommerce: what each party has said, why app tokens cannot be revoked by merchants, the hours lost at each step, and why the app is not BigCommerce's sub-processor under UK GDPR.

Monday 21 September

Editorial illustration for the briefing: AWS quarantines a leaked access key in 10 seconds, but the key keeps working for anything not on the deny list

Breaches and Incidents21 Sept 2026

AWS quarantines a leaked access key in 10 seconds, but the key keeps working for anything not on the deny list

AWS's AWSCompromisedKeyQuarantineV3 went on 10 seconds after a test leak. It is a deny list, not a lockdown: what it blocks, what it leaves open, and what you still have to do.

Editorial illustration for the briefing: September Windows updates quietly stop File History backups; Entra's 1 February SMS cut-off has no opt-out

Breaches and Incidents21 Sept 2026

September Windows updates quietly stop File History backups; Entra's 1 February SMS cut-off has no opt-out

File History can stop backing up after September's Windows updates, mostly without a true error. Entra ID retires Microsoft-provided SMS and voice on 1 February 2027. What Microsoft requires, what it only recommends, and what to do.

Sunday 20 September

A wall of screenshot thumbnails and metadata fragments interrupted by a broken digital lock.

Breaches and Incidents20 Sept 2026

Gyazo exposed about 492.4 million image records. Its notice cannot rule out private-image viewing

Gyazo confirmed exceptional metadata exposure and a list of private image files. The disclosed fields can reconstruct the context around screenshots and drive secondary compromise.

Breaches and Incidents18 Sept 2026

Brevo's attacker hostname sat in a public certificate log for 19 days before the ClickFix injection

A stolen Cloudflare key let an attacker rewrite Brevo's embedded scripts at the CDN edge, so origin files and their timestamps never changed. The earliest public evidence was a certificate logged 19 days before the injection.

Thursday 17 September

A closed laptop with a steel padlock resting on it, beside keys, a circuit board, a network device and a monitor on a desk at night.

Breaches and Incidents17 Sept 2026

KB5124008 revives a dormant Credential Guard setting and breaks domain trust below Server 2025

KB5124008 makes Windows honour Machine Identity Isolation settings dormant since April 2025, breaking domain trust below Server 2025 level. What Microsoft says, what it does not, and the safe order of work.

Sunday 13 September

Breaches and Incidents13 Sept 2026

Brevo’s SAML flaw crossed 138 customer accounts. Six sent phishing through legitimate infrastructure.

A Brevo SAML scoping failure let one organisation’s identity assertion cross into other customer accounts.

Wednesday 9 September

Breaches and Incidents9 Sept 2026

NATS fixed the flight-processing system. The airport disruption kept moving.

The system was restored on 8 September. The aviation network still had a backlog to clear. A sourced timeline and worked recovery example explain the gap.

Tuesday 1 September

Breaches and Incidents1 Sept 2026

Hundreds of fraudulent Pix transactions, and nothing was forged. The only sum Google names is tens of thousands.

Google reports Breeze Comet running two waves of fraudulent transactions through Brazilian payment systems. The count is a victim’s, the only money figure is in a different section, and no rail validates intent.

Monday 31 August

An airport car park barrier arm raised at night beside a weathered number plate recognition camera on its post, wet tarmac below, captioned two 72-hour clocks, only one of them started, and 8.7 million customers

Breaches and Incidents31 Aug 2026

Manchester Airports breach reaches 8.7 million customers. Two 72-hour clocks applied, and only one of them ever started

Gigabytes are not people. The verified finding is one authenticated record carrying far more than MAG disclosed, and a NIS duty that never engaged.

Sunday 30 August

A white electrical plug hanging loose in front of a dark wall socket, captioned: six critical flaws, NVD scored none of them. 0 of 8 identifiers independently analysed.

Breaches and Incidents30 Aug 2026

Six critical WordPress flaws in ten days. NVD independently scored none of them, and the claim that plugins cause most compromises has no current source

The 91% figure describes the vulnerability catalogue, not the cause of breaches. The only quantified entry-vector number anyone can cite is a 2016 survey of about 222 sites.

A brass mechanical counter drum caught mid-rotation in deep shadow, captioned: the fix went public, the chains heard last. 20 hours 5 minutes from that release to the first drain.

Breaches and Incidents30 Aug 2026

Cosmos Labs published the security fix 28 hours before it warned the chains. Six networks were drained of about $5.7 million

Cosmos Labs' own policy calls for private distribution before public disclosure on a network-wide risk. The advisory also never reached the global GitHub database, so no dependency scanner ever raised it.

A long blank unprinted paper roll coiling away into darkness, captioned: 284 million records, not 284 million people. 14.9% of revenue, in the units named.

Breaches and Incidents30 Aug 2026

ShinyHunters claims 284 million McKesson records. It is a row count, and the units McKesson named are 14.9% of the business

Every technical detail of this intrusion is single-sourced to the attackers. The one number McKesson has published points the other way.

Tuesday 21 July

Breaches and Incidents21 Jul 2026

Ransomware playbooks keep failing at the same step: recovery

Ransom demands are collapsing and backups are working. Average recovery cost still rose 11% to $1.7m, and JLR lost five weeks of production for a modelled £1.9bn. The money moved from the ransom to the restore.

Breaches and Incidents21 Jul 2026

Half of breaches now involve a third party. Every clock starts too late

A 72-hour clause is not a control, it is an accounting mechanism. The clock starts at the vendor's awareness, which is the one variable your contract cannot set.

That is every briefing in this category
