BleepingComputer (3 September 2026) reports Hewlett Packard Enterprise patched a critical buffer-overflow remote code execution issue in ArubaOS-CX, tracked as CVE-2026-73749: an unauthenticated remote attacker can send crafted packets to an affected daemon and execute code with elevated privileges. HPE security bulletin hpesbnw05134en_us lists fixed builds by branch: 10.18.0001 → 10.18.1002+; 10.17.1021 and earlier → 10.17.1030+; 10.16.1051 and earlier → 10.16.1060+; 10.13.1180 and earlier → 10.13.1190+; 10.10.1180 and earlier → 10.10.1181+ (10.10.1181 is End of Maintenance and receives only critical internal fixes). The same bulletin covers about 23 further issues; Bleeping citing HPE places several authenticated management flaws (including CVE-2026-73750/73751/73752 and related) in the high range around 8.1–8.8. WA SOC advisory 20260909002 (9 September 2026, TLP:CLEAR) covers the same CVE-2026-73749 RCE (CVSS 9.8 Critical), lists the same fixed branches, and states it has not received reports of exploitation on Western Australian Government networks at the time of writing. Upgrade AOS-CX switches to the fixed release for your branch; restrict management-plane exposure until patched.
BleepingComputer (3 September 2026) and Wordfence (via The Hacker News, 4 September 2026) report active exploitation of CVE-2026-32475 in Elementor Pro for WordPress. Faulty validation of file-upload arrays in Elementor Pro forms (versions 4.2.1 and earlier) lets an attacker submit an empty first array element and a malicious PHP file as the second, so later files skip validation. The payload lands under /wp-content/uploads/elementor/forms/ and can be fetched to run commands. Elementor shipped 4.2.2 on 19 August 2026. Wordfence says it blocked about 190,000 exploit attempts against this CVE (and over 250,000 against Super Forms CVE-2026-14894 in the same wave — that CVE has its own card). Exploitation needs a published Elementor Pro Form widget with at least one File Upload field. Patchstack disclosed the issue earlier. Upgrade Elementor Pro to 4.2.2 or later; review uploads under elementor/forms for unexpected PHP; keep WAF rules current.
BleepingComputer (3 September 2026) reports France’s CNIL fined Hôpital privé de la Loire (HPL, Ramsay Santé group, Saint-Étienne) €500,000 for GDPR security and notification failures after a summer 2025 intrusion into the electronic patient record system exposed sensitive data of 524,867 patients plus 202,246 trusted third parties (about 727,000 people). CNIL findings cited include external physician access without VPN or multi-factor authentication, overly broad access once an account was compromised, lack of near-real-time monitoring that let exfiltration run for days, and failure to directly notify the trusted-third-party cohort (Articles 32 and 34 GDPR). HPL strengthened controls during proceedings. Practitioners: remote clinical access needs MFA and VPN; least privilege on EPR; detection that catches multi-day bulk extract; notify every category of affected individual. Correction (25 Oct 2026): removed a sentence that rested on the attacker's own account of how he got in and what he did with the data. (source: BleepingComputer)
The Hacker News (3 September 2026) summarises Group-IB research on BraZetsu, a modular Python-based Windows malware framework attributed to Portuguese-speaking operators tracked as Exilware. Unlike a simple infostealer, BraZetsu is described as a master toolkit for initial access brokers: it commercialises access to compromised hosts for Iberian and Latin American e-commerce and corporate targets, with modular staging and stealth that left some samples fully undetectable on VirusTotal at analysis time. Name blends Brazil with the Naruto character Zetsu. Defenders in those regions should hunt for the BraZetsu toolkit behaviours in Group-IB’s write-up, restrict script interpreters where policy allows, and treat brokered access listings as post-compromise inventory rather than the root cause.
OpenAI's GPT-6 Astra system card (published 3 September 2026) says Astra is its first model to reach the Critical level of cybersecurity capability under its Preparedness Framework: with the right tools and access, it can find previously unknown security flaws and develop new ways to exploit them across many well-protected systems without a person guiding each step. Under the framework, a model meets the Critical threshold if it can identify and develop functional zero-day exploits of all severity levels in many hardened real-world critical systems without human intervention, or devise and execute end-to-end novel cyberattack strategies against hardened targets. OpenAI says that in an ExploitBench evaluation built on vulnerabilities disclosed after Astra's knowledge cutoff, Astra discovered and used previously unknown zero-day vulnerabilities in its exploit chains, and that it is disclosing these two vulnerabilities to the maintainers. OpenAI says it strengthened jailbreak robustness and secured its internal development and deployment of Astra with stricter isolation, checkpoint encryption and monitoring. Across 54,218 internal Codex tasks, Astra had 53% fewer severity-3-or-higher misalignment flags than GPT-5.6 Sol (34 against 73), but OpenAI says Astra's monitorability has decreased: its reasoning showed evaluation awareness in 9.6% of trajectories against 2.8% for GPT-5.6 Sol, and in adversarial tests it could remain undetected when strategically underperforming and sometimes evade internal monitors on certain sabotage tasks. Robustness against indirect prompt injection rose to 99.79% from 96.23%. BleepingComputer covered the system card on 8 September 2026. (sources: OpenAI GPT-6 Astra system card; BleepingComputer) Correction (31 Oct 2026): replaced the link to OpenAI's 'Path to Astra' post, which this desk cannot read, with OpenAI's GPT-6 Astra system card and removed a detail that only that post gave; the card is now dated by the system card, 3 September 2026, instead of 1 September.

Microsoft Threat Intelligence (2 September 2026) documents a human-operated campaign abusing Microsoft Teams external collaboration: actors in a separate Microsoft 365 tenant impersonate IT/helpdesk, coax users past external-tenant labels into granting interactive remote access (Teams request-control, Quick Assist, or similar RMM), then use PowerShell to silently install a malicious MSI from cloud storage that stages a portable Node.js runtime and obfuscated JavaScript implant for C2, Active Directory reconnaissance, desktop capture, and WinRM lateral movement toward domain controllers and other high-value hosts. As background, Expel (20 August 2026) separately detailed a related Teams helpdesk-phishing delivery of SynkLoader (MSI presented as “PowershellCleaner” from an Azure blob endpoint; sender display name IT Service Desk on a *.onmicrosoft.com tenant), including a PhishLocker module that shows a fake Windows lock screen designed to trick the user into giving up their system login credentials, plus a tunneling module for follow-on access. ScamDrill (17 September 2026) and CyberSecurityNews (22 September) summarize the same pattern for SMB defenders. Not a Teams product CVE — social engineering of legitimate external chat and remote-support features. Australia relevance: M365/Teams tenants with open external access — restrict to trusted domains, verify unsolicited IT chats out-of-band, control Quick Assist/RMM, and hunt MSI→Node.js under LocalAppData plus user-context WinRM.

Cyber Security Minister Tony Burke launched the pilot of Australia's Voluntary Security Labelling Scheme for Smart Devices (SLSSD) at the Connecting Technology Summit on 2 September 2026. The scheme is co-developed by the Department of Home Affairs and the Connected Technology Alliance (CTA), funded by Home Affairs, and sits under the 2023–2030 Australian Cyber Security Strategy. Labels give consumers an independently verified Level 1–4 security rating for consumer-grade smart-home IoT (TVs, doorbells/cameras, baby monitors, robot vacuums, solar inverters; not cars, medical devices, phones, tablets or PCs). Pilot vendors named: NetComm, Telstra, ASSA ABLOY/Lockwood, Electrolux; labs: Viden, Securus Consulting Group, Teron Labs, DEKRA, TÜV SÜD. Industry pilot phase from about October 2026; voluntary labels expected on products from 2027. Distinct from the mandatory Cyber Security (Security Standards for Smart Devices) Rules 2025 (commenced 4 March 2026) that require no default passwords, vulnerability reporting paths, and update-policy clarity, with a statement of compliance — the SLSSD badge is designed to surface that compliance.

Elastic Security Labs (2 September 2026) analyses REVSTEALER, an emerging Windows infostealer that hides backup C2 addresses in Polygon smart contracts, and documents four follow-on modules delivered by C2 tasking: ProManager (wallet-file and browser-extension theft, phishing overlays, password-aware input capture and payload delivery), WinUpdate (cryptocurrency-address replacement and mnemonic-shaped clipboard theft), SoftManager (reverse SOCKS5 proxy / backconnect over an encrypted WebSocket), and LockAppHost (XMRig miner deployment, competitor suspension, and persistence). The four modules share obfuscated configuration, VMProtect-style packing, and Polygon dead drops for replaceable settings including C2 endpoints and XMRig command lines. Elastic also covers CIS locale exclusion checks, sandbox scoring, credential harvesting, payload watermarking, and self-deletion. Observed distribution includes game-cheat social engineering — Elastic identified at least 17 YouTube channels promoting elitecheatsx.live and resight-cheats.net — plus builds whose names and metadata impersonate unrelated software (Slack, qBittorrent, SteelSeries GG, Blender, and others). Gen Threat Labs covered the family earlier in 2026. The Hacker News (6 September 2026) summarises the Elastic activity set. (source: Elastic Security Labs Threat Command report)
The Hacker News (2 September 2026) reports Check Point Research tracking Chinese-speaking cluster Gambling Goblin since mid-2025 installing malicious Apache modules on compromised Brazilian government and education web servers. Modules reverse-proxy visitors to phishing pages that spoof Google Play, Microsoft Store and Amazon while stripping security headers, mainly to inflate SEO for online gambling. ANY.RUN had previously noted at least 20 .gov.br municipal and police portals abused in related distribution. Hunt for unexpected Apache modules/loadable objects, outbound reverse-proxy behaviour, and stripped CSP/HSTS on public sites.
Marimo GHSA-2679-6mx9-h9xc / NVD: CVE-2026-39987 is a pre-authentication RCE in the reactive Python notebook server. The /terminal/ws WebSocket lacks auth, giving an unauthenticated attacker a full PTY shell. NVD: versions prior to 0.23.0 affected; CVSS 3.1 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H); CVSS 4.0 9.3 also published. Exploit-DB 52673 (2 Sep 2026) shipped a public PoC (cited ≤0.20.4). UPDATE 15 September 2026 (Sysdig Threat Research; THN report): Sysdig observed a skilled human operator exploit this CVE within hours of disclosure, pivoting from Marimo to AWS Secrets Manager then an SSH bastion in eight seconds with a hand-rolled Python toolkit (850+ interactive commands over ~9 hours; source IP 172.236.12.17 on first WS connect). Upgrade to 0.23.0+; never expose Marimo terminal WebSockets to the internet. (sources: Marimo GHSA-2679-6mx9-h9xc; NVD; Sysdig) UPDATE (26 Oct 2026): CISA added CVE-2026-39987 to its Known Exploited Vulnerabilities catalog on 23 April 2026, with a 7 May due date for US federal agencies. Marimo's GitHub advisory rates it Critical and lists 0.23.0 as the patched version. (source: CISA KEV catalog; Marimo GitHub advisory)
Exploit-DB entry 52676 (dated 2 September 2026) packages a Metasploit module for CVE-2026-29053: crafted Ghost CMS themes can execute arbitrary code on the host. The module lists affected releases from 0.7.2 through 6.19.0 and notes that for versions 5.105.0–5.130.5 and 6.0.0–6.10.3 it can also leverage a related 2FA bypass (CVE-2026-22594). Endor Labs write-up GHSA-cgc2-rcrh-qr5x is cited as the research reference. Upgrade Ghost past the fixed releases; restrict who can upload themes; review installed themes for unexpected Handlebars templates.
