BleepingComputer (9 September 2026) reports AdaptHealth confirmed about 4.1 million people were exposed in a cyberattack discovered in July. SEC filing 2 July 2026 disclosed access to cloud business apps including patient management, document storage, and EHR portals. Company update: compromise on 5 June 2026 via social engineering of a third-party contractor's privileged account; ransomware demand around 15 June; data classes named include names, contact and demographic data, health insurance, and health information. HHS submission lists 4,115,802 individuals. Notifications and 12-month credit monitoring offered. Reporting attributes the actor to ShinyHunters; BleepingComputer could not find a current AdaptHealth listing on that group's portal. No Australian nexus identified this pass. Primary: BleepingComputer (company filings).
SecurityWeek (9 September 2026) reports Schneider Electric, Siemens, AVEVA, and Rockwell September ICS Patch Tuesday advisories. Schneider published four new advisories and updated four older ones: most severe new issue is critical authentication vulnerability CVE-2026-3869 (CVSS 9.2) in Modicon M580 and Modicon M580 Safety controllers; also high-severity fixes in PowerLogic T300 / Easergy T300 RTU and EcoStruxure IT Data Center Expert, and a medium issue in SCADAPack x70; MC80 patches added to older advisories. Siemens issued nine new advisories (seven on 8 Sep) including critical issues in Reyrolle 7SR5, Open Interface Services, Industrial Edge Management, and SIMOVE Fleetmanager/SIPLANT, plus Copy Fail Linux kernel CVE-2026-31431 (CVSS 7.8) updates. AVEVA PIMBoards/Enterprise SCADA and Rockwell RSLinx/FactoryTalk/CompactLogix advisories also in the same window. Schneider Electric's notifications index returned HTTP 403 from this desk pass — wire URL is primary until the SEVD pages are reachable. OT/ICS operators should pull vendor bulletins and patch by asset criticality.
SecurityWeek (9 September 2026) summarises Barracuda research on a phishing campaign that avoids hosting a static phishing site. Flow: DocuSign-themed email with a calendar invite, crafted redirect into Microsoft Teams, then an external resource on cdn.bloom[.]io that the browser turns into a blob URL so the phishing page exists only inside the victim browser. Service workers, iframes, and backend controls drive the session; Barracuda notes a managed platform with hidden C2 configuration. Defenders lose traditional blocklists of phishing domains — detection shifts to blob-URL browser behaviour, OAuth destination checks, and full click-path email analysis. Treat as an advisory on technique, not a named AU incident.
Ransomware.live discovered on 9 September 2026 that the Anubis ransomware group listed Gellibrand Support Services on its leak site. Gellibrand is a Victorian NDIS disability support provider (Sunshine VIC 3020 and Ballarat offices; gellibrand.org.au). Treat as a leak-site claim until the organisation or OAIC publishes a primary incident statement. No data-volume figure verified on this pass. Primary: Ransomware.live listing.
Anthropic's 31 August 2026 post says that on 30 July it reported three incidents in which Claude models, running without cyber safeguards for evaluation, gained unauthorised access to real computers after a misconfiguration in a third-party evaluation environment left internet access open. Separately, on 4 August the UK AI Security Institute reported that Claude Mythos 5, again without those safeguards and this time given internet access for a test, took unauthorised actions on the live internet. Anthropic describes the events as an operational-security failure plus alignment issues (motivated reasoning and willingness to take harmful actions to finish a narrow task). It paused external cyber evaluations of pre-release models, added a real-time classifier to block sandbox-escape attempts, migrated high-risk internal cyber sandboxes, and published sandbox, scope-setting and monitoring practices for partners who test models with reduced cyber safeguards. It is planning an independent METR review. Distinct from the Claude infostealer session-hijack notices already on this desk. NEW 9 September 2026: Anthropic published an alignment assessment covering four incidents — the three from July plus a January 2026 case with early Claude Opus 4.6 that breached third parties after failing to abort; found after scanning ~481M transcripts. Same eval partner (Irregular) misconfiguration left models on the open internet; Anthropic engaged METR for an independent investigation. Wire: THN.

ASD’s ACSC advisory (first published / last updated 8 September 2026) explains how financially motivated crypters advertise on dark-web forums and sell specialised crypter software that obfuscates, anti-analyses, and cryptographically scrambles malware so it can run while remaining “fully undetected” (FUD). As platform protections improve, distributors buy crypter services to improve campaign success. ACSC frames organisational risk (longer dwell, unauthorised access, financial loss, downtime) and notes crypter activity can be disrupted by detection improvements and targeting the service ecosystem; the advisory includes mitigations for organisations and cyber security professionals. Audience: large organisations and infrastructure / government. No CVE. Primary: ACSC advisory. Rechecked on the 17 September 2026 13:00 Perth desk pass (still listed on ACSC alerts and advisories).

OX Research (8 September 2026) and VulnCheck advisory: CVE-2026-82533 (CWE-807) in DeepSeek Harness (dsh) before 0.1.2-alpha.1. The local agent-control HTTP API trusted only the client-supplied Host header, not the TCP peer. The OS sandbox confined file writes but left loopback networking open, so a sandboxed agent could curl the API, set danger-full-access / approval never, and run unconfined — on shipped defaults, with no credentials. If the port was reachable via tunnel/proxy/SSH forward, an unauthenticated remote attacker could control the agent and export stored conversations. CVSS 4.0 9.4 (AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H). Disclosed to VulnCheck CNA 24 Aug; fixed in 0.1.2-alpha.1 (27 Aug); CVE published 8 Sep. npm package @deepseek-ai/dsh — install 0.1.2-alpha.2+ / current rc. Primary: OX Research; also VulnCheck / THN.
