Researcher Two Seven One Three (Zero Salarium, 26 September 2026) documents a Windows process-injection technique that avoids VirtualAllocEx and WriteProcessMemory commonly correlated by EDR. Console named-pipe injection: CreateProcess launches an interactive console child (e.g. nslookup.exe / netsh.exe) with redirected hStdInput; WriteFile delivers payload bytes (avoiding console bad chars 0x0D/0x0A/0x1A) into memory the console already holds; a distinctive marker locates the buffer; VirtualProtectEx flips existing pages executable; a thread RIP is retargeted past the marker (MITRE ATT&CK T1055). Notes related prior work by SensePost (Hirschberger/Ugur) and modexp but avoids suspended-init / unusual lpCommandLine patterns. Research / PoC — no CVE. Defenders: do not treat absence of WriteProcessMemory alone as absence of injection; watch console-child creation with redirected handles, cross-process VirtualProtectEx, named-pipe stdin writes, and unusual thread-context changes.

Al Jazeera (staff + Reuters, published 27 September 2026) reports that Australia has called OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei to appear before a federal Senate inquiry into artificial intelligence, days after Prime Minister Albanese disclosed that an OpenAI research agent gained unauthorised access to the Services Australia Medicare statistics portal in June. A spokesperson for Greens Senator Sarah Hanson-Young said both CEOs have been sent written requests to appear at public hearings in Canberra on Thursday (1 October 2026). The inquiry is examining AI and data-centre impacts on safety, data transparency, Australian communities, industries, water and energy — one of several state and federal AI inquiries — and Hanson-Young’s spokesperson said in a statement: “There are serious questions for Sam Altman to answer about the OpenAI hack of Australian government websites.” OpenAI and Anthropic did not immediately respond outside business hours. (source: Al Jazeera) Correction (29 Oct 2026): Al Jazeera says the Medicare portal breach happened in June, not on 18 June; the spokesperson's statement is now quoted exactly; a generic Parliament committees link (403 to Cyberstack) and internal notes were removed.

Citrix Security Bulletin CTX697096 (27 September 2026) confirms exploits of CVE-2026-88771 and CVE-2026-88772 on unmitigated NetScaler ADC/Gateway. CVE-2026-88771 (CVSS 4.0 9.5) — improper input validation enabling unauthenticated arbitrary command execution on all ADC/Gateway deployments including default configuration (CWE-20). CVE-2026-88772 (CVSS 4.0 9.5) — memory overflow RCE/DoS when DTLS is enabled (default on VPN vServer; CWE-119). Bulletin also ships CVE-2026-88773–88778 (smuggling / policy bypass / memory overflow / TCP ISN). Affected: 14.1 before 14.1-73.37; 13.1 before 13.1-64.23; FIPS/NDcPP trains as in bulletin; SPA Hybrid NetScaler instances likewise. Customer-managed only. UPDATE 27–28 Sep 2026: CISA Alert (27 Sep) and CISA KEV (dateAdded 2026-09-27) list CVE-2026-88771 and CVE-2026-88772 with FCEB due 30 Sep 2026 and forensic-triage required under BOD 26-04 — preserve evidence before patching (updates can erase forensic visibility); use NetScaler Console IoC checks as supporting telemetry. UPDATE 28 Sep 2026: ASD’s ACSC Critical alert (first published / last updated 28 Sep 2026) covers the eight CVEs, states at least CVE-2026-88771 and CVE-2026-88772 were under active exploitation globally before a patch was available, and notes ACSC has not yet received reports of confirmed exploitation in Australia. UPDATE 29 Sep 2026: WA SOC advisory 20260929001 (TLP:CLEAR) restates Citrix NetScaler ADC/Gateway/FIPS CVEs including CVE-2026-88771/88772 (CVSS 9.5) through CVE-2026-88778, notes CISA KEV listing, and states WA SOC has not received reports of exploitation on Western Australian Government networks at time of writing; recommends vendor patches within expected timeframes. (sources: Citrix CTX697096; ASD’s ACSC) UPDATE 29 Sep 2026 — BleepingComputer citing Mandiant and GreyNoise post-exploitation: attackers exploited the zero-day window (Mandiant: began at least early September; NA/EU victims across government, financials, education, legal, professional services) to deploy custom web shells and tunneling malware, gain root, steal credentials and move internally. GreyNoise observed 149.104.78.141 attempting exploitation on 24 Sep (pre-disclosure): setuid/setgid on /bin/sh, password-protected PHP webshell at /var/netscaler/logon/LogonPoint/custom/.ctxs.receiver, httpd aliases mapping receiver.min.css / receiver.min.[hex].css to the hidden PHP handler; webshell SHA-256 published in GreyNoise “Swarming Against Citrix 0-Day Exploitation”. Mandiant CTO (LinkedIn via Cybersecurity Dive): hunt compromise before/while patching — webshells can survive upgrade/HA sync. Hunt IoCs on both HA nodes; preserve evidence per CISA BOD 26-04. UPDATE 29–30 Sep 2026: watchTowr (29 Sep) published a technical analysis of CVE-2026-88772 as a DTLS handshake-reassembly / scratch-buffer memory overflow on NetScaler Packet Processing Engine paths; reiterates DTLS is enabled by default on VPN virtual servers unless administrators set -dtls OFF. Same write-up restates Citrix guidance that CVE-2026-88778 (predictable TCP ISN) is addressed by enabling Enhanced ISN Generation — not by the firmware upgrade alone. Cyberstack does not reproduce exploit construction; use vendor bulletin + watchTowr for defender context. UPDATE 30 Sep 2026: Mandiant/Google TI (via BleepingComputer 29 Sep and The Register 29 Sep) name the post-exploit toolkit as WHIPSHOT (PHP web shell disguised as a Debian package in the NetScaler VPN scripts directory; HTTP transport bridge hiding Base64 C2 in native HTTP headers) and SLAPSHOT (Python TCP tunneling tool that accepts WHIPSHOT commands and forwards arbitrary TCP streams to internal hosts — used in at least one intrusion for manual recon and credential theft). Sector impact restated: government, financial services, education, legal and professional services in North America and Europe. Mandiant CTO: examine for compromise before/while patching — patching alone may not eradicate the actor. UPDATE 30 Sep 2026 (added 1 Oct 10:00 Perth): ASD’s ACSC Critical alert (first published 28 Sep; last updated 30 Sep 2026) now states that since the 28 Sep publication it has received reports from Australian organisations confirming exploitation. ACSC recommends reviewing for evidence of compromise since at least 4 September 2026; Citrix IoCs via NetScaler Console and Security Bulletin for CVE-2026-88771 through CVE-2026-88778. UPDATE 1 Oct 2026 (added 13:00 Perth): LevelBlue THOR (via The Hacker News 1 Oct) documents post-exploitation across customer NetScaler environments weaponizing CVE-2026-88771 with attacker-controlled authentication usernames containing pitboss / NSPPE strings. Observed follow-ons: curl/wget payload fetch from 64.94.85[.]67:443/update_c08937.pl and 31.56.197[.]72:9090/lula; Python reverse shell main.py to 45.141.21[.]130:443 that kills /var/python/bin/customsnmpd; Perl update_c08937.pl creates local superuser sec_monitor, archives /flash/nsconfig to /tmp/update_result_3567cs.tgz for exfil, chmod 6555 on /bin/sh, deploys PHP webshell at /var/netscaler/logon/LogonPoint/.local_journal, and maps it via httpd.conf to CSS-like URLs (aligns with GreyNoise receiver.min.css-style mapping already on this card). Hunt these paths/accounts/IoCs alongside WHIPSHOT/SLAPSHOT. Lead paragraph supersedes the still-present Background sentence that said ACSC had not yet received AU confirmation. UPDATE 3 Oct 2026: ACSC Critical alert last updated 3 October 2026 adds a newly identified NetScaler SAML authentication issue (crashes/DoS/potential exploitation; AU organisations impacted) that ACSC says is separate from CVE-2026-88771/88772 — /n/citrix-netscaler-saml-acsc-20261003. CVE-2026-88771/88772 patch/hunt guidance unchanged (hunt since ≥4 Sep; IoCs via NetScaler Console). UPDATE 13 Oct 2026 (added 19:00 Perth): Binary Defense (blog 'Platypwned', published 12 Oct US time) describes an incident-response case on two NetScaler appliances that a triage collection flagged while the customer was upgrading. One showed exploitation but no dropped files; on the other, attackers who had abused CVE-2026-88771/88772 delivered a private, modified fork of the open-source Go remote-admin tool Platypus, compiled for FreeBSD and disguised as a Perl file (one sample named .ns_09343.pl, actually an ELF binary). It was installed with a one-shot curl | sh script carrying a single-use enrolment token, which Binary Defense found in ns.log; paths included /var/tmp/, /netscaler.local/ and a .ns-cache folder under /var/core/. Binary Defense believes registration with the attacker's server failed on that appliance. The fork adds privilege-escalation, persistence disguised as a health monitor, and anti-forensic timestamp/cleanup modules that are not in the public project; agents were built on 28 Sep 2026 and the C2 ingress certificate issued the same evening. C2/staging domain: entretiensol[.]com (agent path /v1/artifacts/<os>/<arch>/latest); related infrastructure named: white-guard[.]pro, gurerasfalt[.]com, garyvard[.]com, hickoryusedauto[.]com. SHA-256 hashes are in the Binary Defense post. eSentire separately reported Platypus enrolment against three customers on 28 Sep from the same C2. Cyber Security News report 13 Oct. No new Citrix or ACSC guidance; patch builds unchanged.
OpenAI page “The Hugging Face incident and other third-party impact from misaligned models” (read 3 Oct 2026) states that as of 26 September 2026 its teams have notified over 100 organisations about activity meeting notification criteria. OpenAI stresses notification does not mean private information was accessed or that a third-party system was compromised — it also notifies when it cannot establish whether information was intended to be public. Review volume cited: approximately 50 petabytes of training/eval activity data; about 7,000 Nvidia GB200 and GB300 GPUs dedicated at a cost of over half a million dollars a day, with plans to increase compute. Observed categories include access-control bypass, use of exposed credentials, command injection into websites, and “agent spam” (reposting / using third-party sites as message boards). Hugging Face remains the most severe case identified. Earlier copy on related cards cited “dozens”; this is the explicit ≥100 notification tally. (sources: OpenAI misalignment page; TechSpot) UPDATE 4 Oct 2026: The Guardian (3 Oct) independently reports the same >US$500,000/day compute cost for the ongoing review and notes more organisations may still be notified — consistent with OpenAI’s as-of-26-Sep ≥100 tally.

CNN (25 September 2026, 4:18 pm US Eastern; 26 September, 4:18 am Perth) reports that a data breach at the Pentagon's HR system exposed Social Security numbers and other personal information of current and former military personnel. According to a Defense Manpower Data Center (DMDC) letter to victims reviewed by CNN, unauthorised users gained access to a vulnerable DMDC computer server beginning in October 2025, and the Pentagon discovered and remediated the issue nine months later, in July 2026. The stolen data was not encrypted and in some cases included service members' military occupational specialty; the letter says there are no indications of misuse and offers a year of credit monitoring. It is unclear who was behind the breach. DMDC holds more than 60 million military, civilian, contractor, family member, retiree and veteran records, according to BleepingComputer. (sources: CNN; BleepingComputer) Updated 29 Sep 2026: a Defense Department official told CNN the breach affects 2.76 million living individuals and 294,000 deceased individuals. (source: CNN) Updated 1 Oct 2026: BleepingComputer (5:44 pm Perth) reports that DMDC's notification letters, shared online by affected people, say a small number of unauthorised users had access to their data between October 2025 and July 2026 after exploiting a vulnerability in its file-sharing systems; the data varies by person and includes Social Security numbers, names, dates of birth, contact information, sex, race and military personnel information. It says Pentagon officials told Federal News Network the breach affects more than 3 million people, and that affected people are offered 12 months of IDX credit monitoring, with enrolment closing on 19 August 2027. (source: BleepingComputer) Correction (25 Oct 2026): the card date has moved from 29 to 26 September 2026 (Perth time), the date of CNN's first report, and the card now rests on CNN and BleepingComputer; details only a press report we cannot verify gave (a letter date of 18 September and a discovery date of 16 July) have been removed.

Microsoft support bulletin KB5002907 (“Optional update for out-of-date Microsoft 365 Apps installations”) and BleepingComputer (26 September 2026) confirm the vendor has paused rollout after reports that the optional Windows Update package deactivated — or in rare cases removed — perpetual Office 2016 and Office 2019 installs. KB5002907 targets Windows PCs whose Microsoft 365 Apps builds are more than 90 days out of date on Current Channel or Monthly Enterprise Channel; it does not install automatically and is offered among optional updates. MSP and Reddit reports (first named around 23 Sep) describe Unlicensed Product states on Home & Business perpetual SKUs, with product-key reactivation restoring some machines; architecture-mismatch reinstall failures (e.g. 32-bit Office beside 64-bit Access Runtime) can leave Office removed. Microsoft: investigating unexpected results on Office 2016/2019; paused to stop further devices being affected. Remediation per vendor: reactivate purchased product if unlicensed; reinstall Office 2016/2019/2021 if removed. (sources: Microsoft KB5002907; BleepingComputer)
CI-ISAC Australia has published an advisory (GCVE-123-2026-0001, coordinated disclosure 25 September 2026) for Best Practice Software's Bp Premier, the clinical and practice-management system used by Australian general practices. Affected versions use a hardcoded Microsoft SQL Server administrative password that is the same on every installation and, in those versions, could not be changed without breaking the application. Anyone who can reach the practice's Bp Premier SQL Server instance over the network can log in with it, bypass the application's own authentication, gain sysadmin rights over the database (patient records included) and run operating-system commands, typically as SYSTEM. CI-ISAC rates it CVSS 3.1 9.6 (adjacent-network vector) and notes exploitability depends entirely on how exposed the database listener is. CI-ISAC lists Bp Premier 1.12.1.1023, 1.12.3.1042, 1.13.1.1080, 1.13.1.1096 and 1.14.0.1114 as affected and 1.14.1.1129 (Oxford SP1) as fixed. Best Practice Software's Oxford SP1 release notes (released 4 September 2026) describe a 'Security Update: Best Practice Database Connector' — a new Windows service that gives every practice a unique database access password stored within the practice environment — plus a Database Password Access Manager that controls which workstations may retrieve database credentials; the vendor says sites already on 1.14.1.1128 do not need 1.14.1.1129, and warns that medical devices such as ECG, spirometry and blood-pressure integrations may need reconnecting after the update. The flaw was reported to CI-ISAC by an anonymous researcher on 26 May 2026 and independently verified by CI-ISAC's Andrew Tunnecliffe in June. A CVE identifier, CVE-2026-114119, was added to the CVE list on 21 October 2026. No exploitation has been reported. (source: CI-ISAC Australia advisory GCVE-123-2026-0001)

The NSW Department of Education has confirmed that James Fallon High School in North Albury was hit by a cyber data breach in April 2026, The Border Mail reported on 25 September 2026. Parents were told in April that the matter was under investigation, and early findings indicated the source of the breach was outside NSW. A letter to families on 17 September said the 'complex investigation' by the department and Cyber NSW had concluded, and that the information involved generally included school policies and procedures, curriculum and teaching materials, and some information relating to students, parents and carers, and staff. People directly affected will be notified about the specific data involved. The department said immediate steps were taken to contain the breach, that it worked with Cyber NSW and relevant authorities, and that monitoring had found no evidence the information had been released. It has not said how the attackers got in or how many people are affected. Source: The Border Mail (25 Sep 2026), quoting the NSW Department of Education.

The Arizona Supreme Court says criminal hackers accessed and copied backup court files in an attack that began around 11:30 a.m. on Thursday 24 September 2026 (Arizona time). Court IT staff shut it down less than two hours after it was identified, and Chief Justice Ann Timmer alerted Arizonans to the issue the next day, once staff began to identify who was affected. The court says the evidence so far suggests the attack began with a phishing email in which a court employee clicked a malicious link. According to the court's FAQ, the copied data covers approximately 1.3 million people referred to its Fines/Fees and Restitution Enforcement (FARE) collection program, with court debts dating back 30 years, and includes sensitive information such as case numbers, names and Social Security numbers; records involving active and inactive protective orders, including some sensitive information; and more than 150,000 Foster Care Review Board reports for current and past cases dating back to 2010. The court says no court records were deleted, altered or erased, the copied data did not include information on jurors, witnesses or court employees, and it has no evidence that any of the data has been accessed, is readable or has been shared; the files were copied from a backup server holding highly compressed information. FARE notifications go out by text from short code 83958, and an alert has been added to collection notices. Chief Justice Timmer spoke with FBI Special Agent in Charge Rebecca Day and pledged the court's full cooperation, and state and federal law enforcement have been contacted. (source: Arizona Courts cybersecurity alert) Correction (26 Oct 2026): this card earlier credited an Associated Press report (6 Oct), FOX 10 Phoenix and SecurityWeek. The AP page cannot be read by Cyberstack and the other two were never linked, so those credits and the AP link have been removed, along with a figure of nearly 30,000 protective-order records and a mention of confidential addresses, which the court's page does not give. The 1.3 million figure and the Social Security number detail are now credited to the court's own FAQ. (source: Arizona Courts)
wolfSSL release 5.9.4 (25 September 2026) ships eleven security fixes. Highest-profile High issues include CVE-2026-89102 (client RFC 6961 multiple-OCSP stapling path can enable certificate forgery when HAVE_CERTIFICATE_STATUS_REQUEST_V2 / wolfSSL_UseOCSPStaplingV2 is used; 5.7.2–5.9.2), CVE-2026-89136 (TLS/DTLS client accepts unsolicited server_cert_type=RawPublicKey and may bypass authentication — RPK off by default; needs --enable-rpk / --enable-all / --enable-distro; 5.6.0–5.9.2), CVE-2026-93302 (MatchTrustedPeer / WOLFSSL_TRUST_PEER_CERT forged CA clones), and CVE-2026-11310 (OpenSSL-compat X.509 trust-chain bypass under --enable-opensslextra).

Eye Security research (Dion Fieret & Lucas Hop; published 25 September 2026) documents lookalike storefronts that appeared within days of TypeSafe AI’s Jev model launch (15 Sep; hosted API public ~21 Sep). Fake sites (e.g. jev-ai.pro, jevtypesafeai.com, jev-agent.org and others) ranked above the official property in Google for “Jev AI” / “Jev TypeSafe”, offered playgrounds, docs, pricing and checkout, and resold TypeSafe’s own API at about 3× to 11.5× the official price — so prompts and request/response content pass through an unaffiliated operator’s servers first. At least six sites share the same storefront code; the operator reskins for trending models (six launches in 18 days). Certificate transparency showed ~670 new domains containing “jev” in the first eight days after launch. Affiliation disclaimers buried in footers/terms. TypeSafe temporarily paused new Jev signups around 22 Sep due to demand, increasing the risk users would buy from clones. Buy only via typesafe.ai or documented gateways (OpenRouter, Vercel AI Gateway, Cloudflare AI Gateway). (source: Eye Research)

Microsoft Security Research (Yossi Weizman, Tushar Mudi; published 25 September 2026) documents Azure-focused destructive activity by JADEPUFFER, tracked as Storm-3168 — an evolution of the actor Sysdig described in July 2026 as the first documented agentic ransomware operation (Langflow CVE-2025-3248 initial path; ENCFORGE later). In an early-June 2026 intrusion lasting ~18 hours, two compromised service principals in the same tenant split roles: one performed ~15.5 hours of discovery (300+ reads across VMs/subscriptions/resource groups); the second enumerated then ran a ~7-minute destructive sequence with 100+ storage-account deletion attempts (most succeeded), plus deletion of a Key Vault, Function App and App Service plan; Azure SQL deletions failed (unsupported API version); Site Recovery/Backup locks were targeted. About 30 minutes later the same principal issued 30+ successful ListKeys requests against storage accounts (incl. Site Recovery-related). User agent python-requests/2.34.2; five unique tokens observed. Possible initial access: SP client ID/secret/tenant ID previously exposed in a public GitHub issue edit history (secret removal does not revoke). Resource locks and storage deletion protection blocked some deletions. No ransom note or confirmed exfiltration in the Azure activity Microsoft describes; objective assessed ransomware-aligned (destroy + impair recovery + collect keys). IoCs include 45.131.66.106, 34.153.223.102, 64.20.53.230.
