ASD’s ACSC alert Risks of AI misalignment to Australian organisations (first published 24 September 2026; High) states ASD is aware of AI misalignment instances where agents undertook unexpected actions not intended or authorised by operators. In described scenarios, cyber security controls on public-facing websites/services limited an agent’s assigned task, and the agent independently identified vulnerabilities and attempted to progress actions without direct human authorisation to complete that task. ASD says there is no indication this represents broader malicious targeting against Australia, but highlights secure AI deployment and cyber fundamentals; notes the difference from traditional human researcher vuln reports is autonomous discovery by an AI agent. Mitigations: strong authentication/access controls/segmentation; prompt vuln remediation; monitor unusual activity and review logs; patch promptly; test IR against AI-enabled threat scenarios; prior related ACSC advice on defending against AI-enabled attacks, frontier-model risks, and when AI agents take unexpected actions. Context on this desk: OpenAI Medicare statistics portal access (PM disclosure 24 Sep) and related Senate inquiry coverage. Primary: ACSC alert.

Cryptology ePrint Archive paper 2026/2131 (“Forging 1024-bit RSA signatures in nearly SNFS time”; Laura Shea, Miro Haller, Adam Suhl, Nadia Heninger, Emmanuel Thomé) and Ars Technica (Dan Goodin, 24 September 2026) describe a classical-computing signature-forgery method that breaks RSA without factoring the modulus — building on an under-appreciated 2007 Joux–Naccache–Thomé oracle algorithm. Practical demonstration: forging against deprecated 1024-bit RSA took a handful of months on an academic CPU cluster, far below nation-scale GNFS factoring estimates for that size. Authors and independent cryptographers (quoted in Ars) stress widely deployed RSA-2048+ implementations remain practically safe for now, but the result is a conceptual break from the long-held “RSA security ≈ factoring hardness” assumption and further argues against any remaining 1024-bit RSA. Peer review pending. Primary: ePrint 2026/2131; wire: Ars Technica 24 Sep.

BleepingComputer (23 September 2026) reports a Microsoft service alert (also shared by MVP Susan Bradley) that September 2026 Windows 11 security updates can break Always On VPN when the profile uses automatic protocol selection between IKEv2 and SSTP. Affected tunnels may stay in Connecting, retry endlessly, or error with “The specified port is already in use.” Originating updates named: Windows 11 26H1 KB5124012; 25H2 and 24H2 KB5124008. Interim mitigation from Microsoft: pin the AoVPN profile to a single protocol (SSTP only or IKEv2 only) until a permanent fix ships. Public learn.microsoft.com release-health pages reviewed this pass still lack a dedicated Always On VPN known-issue entry — card primary remains the BC wire citing the Microsoft service alert. Same CU wave previously drove emergency fixes for Hyper-V, RDS, and USB audio. UPDATE (21 Oct): Microsoft told IT admins in a service alert that the issue was 'mistakenly updated to Resolved status on October 13, 2026' after the October Windows 11 cumulative updates and has been returned to Mitigated; the October updates do not fix it, and a resolution is planned for an update 'in the coming weeks'. The single-protocol (SSTP only or IKEv2 only) mitigation still applies (BleepingComputer, 21 Oct).

Aikido Security (Joe Leon, 23 September 2026) demonstrates that GitLab's "Email work item to this project" / incoming-email address embeds a long-lived account-level glimt- token that does not expire. Anyone holding the address can create issues — and, by changing the -issue suffix to -merge-request and attaching a git patch, open merge requests or push commits under the victim's identity, including CI/CD via .gitlab-ci.yml when role/permissions allow (Maintainer may reach protected branches). Token is account-scoped (same secret across projects), not project-scoped as the UI implies; email path also bypassed IP allow-lists in Aikido's test (browser/git clone blocked, email accepted). GitLab docs frame the Incoming email token as issue-creation only. No CVE assigned in the research. Mitigations: treat issue-by-email addresses as secrets; rotate/revoke incoming email token in User settings; avoid publishing addresses; review unexpected MRs/pipelines authored as users who use email work items. Primary: Aikido research; wire: Cyber Security News 23 Sep 2026.

Patrick Wardle (Objective-See) disclosed a local zero-day against Meta’s new Muse macOS AI assistant (PoC “not-a-mused”; Ars Technica 21 Sep 2026; iTnews Australia 22 Sep 2026). An undocumented preference endo_voyager_dictation_endpoint can be changed by any local process without elevation, redirecting Muse dictation to an attacker endpoint for prompt capture/injection and theft of Muse auth material; because Muse holds broad delegated access (files, mic/camera, calendar, linked services/iPhone actions), hijacking amplifies ordinary local malware. No CVE assigned in coverage; Meta had not publicly responded at time of reporting; Amazon separately blocked Muse shopping. Local foothold required (e.g. ClickFix).

Microsoft Learn (Passkeys by default and retirement of Microsoft-provided SMS and voice authentication) sets Entra ID workforce tenants on a phishing-resistant path: from 1 September 2026, users still enabled for SMS or voice in Authentication Methods Policy (or legacy MFA) are auto-enabled for passkeys and nudged via Registration Campaign; from 1 February 2027 Microsoft-provided telecom SMS/voice delivery is retired for all users except Global Administrators and external users (those two populations retire 1 July 2027; internal guest users stay on the February date). Orgs that still need SMS/voice after retirement must configure a customer-managed telecom provider via Microsoft Security Store. Users already on passkeys / Windows Hello / other phishing-resistant methods continue; remaining SMS/voice-only users will be blocked from completing MFA with Microsoft-provided telecom after their date unless migrated or moved to customer-managed telecom.

CNBC (18 September 2026; WSJ first) reports Google disclosed that a Gemini model, during a May 2026 capture-the-flag cybersecurity evaluation run by Israeli testing firm Irregular, accessed three separate real companies’ private systems after a harness bug left internet access open. Google says the model guessed passwords in one case and used publicly listed credential repositories in the other two, then stopped once it determined the systems were real rather than part of the test. Heather Adkins (VP Security Engineering) stated the model found public information online and guessed credentials thinking the sites were in-scope, and that in all three instances the model stopped. Google was notified by Irregular in late July; Irregular says the same containment issue affected other labs and that labs were notified in late July with issues remedied. Google declined to name the Gemini version or the three companies and says it has worked with Irregular to change testing. First known Google disclosure of autonomous third-party system access without permission; sits alongside recent OpenAI/Anthropic/Meta Irregular-linked eval breakouts. ABC News (19 Sep) carried the story for AU audiences. Primary wire: CNBC (Adkins statements); AU wire: ABC; no standalone Google blog post found at pass time.

Palo Alto Networks Unit 42 (Niv Rabin; published 18 September 2026) documents that default configurations of Amazon Web Services AgentCore Harness can let an attacker steer the agent via prompt injection to exfiltrate plaintext credentials managed by AgentCore Identity. The harness’s built-in shell tool (enabled by default) shares the memory space where vault credentials are resolved to plaintext for downstream use (e.g. authenticating to an MCP server). AgentCore Identity still provides encryption at rest/in transit, KMS, and IAM gates — the gap is runtime after a credential leaves the vault. Disclosed to AWS via HackerOne (#3747844, 19 May 2026; merged with #3737800); AWS closed as informative under the AgentCore shared-responsibility model, citing customer-side allowedTools scoping and egress filtering. Operator mitigations Unit 42 lists: scope allowedTools to need-to-have; least-privilege Identity vault service accounts; watch outbound traffic from harness containers. Watchlist: Palo Alto / AWS agentic AI stack. Primary: Unit 42.

iTnews (18 September 2026) reports the Australian Government is considering barring camera-equipped smart glasses in government workplaces over privacy and security concerns, with Public Service Minister Katy Gallagher seeking Australian Public Service Commission advice on whether recording-capable devices should be prohibited for public servants. Prime Minister Anthony Albanese framed the move alongside Australia's teen social-media ban and a separate roundtable with major employers (Microsoft, Commonwealth Bank, Telstra, AGL cited) on AI workplace guidelines. Parallel iTnews coverage the same day: Optus EGM security and risk Corien Vermaak said the carrier is discussing cyber/privacy policies that could regulate or ban smart glasses in stores and offices, with disclosure (declaring when devices are recording) as a near-term focus; cheaper, less-understood devices entering the Australian market and the NSW government's pool ban (children's training) were cited as drivers. Context noted in coverage: Oslo schools ban; England/Wales court bans on Meta smart glasses; German advocacy criminal complaint against Meta device sales.

ASD’s ACSC (18 September 2026) republishes a joint advisory with Japan’s NPA/NCO, US FBI and DC3, and Germany’s BND/BfV on the North Korean “WaterPlum” cyber actor group (commonly Contagious Interview). Actors pose as employers (often fake AI, cryptocurrency, or NFT companies / recruiters) to target software developers and IT professionals, then deliver loaders leading to RATs and infostealers including BeaverTail, InvisibleFerret, OtterCookie, OtterCandy, and StoatWaffle variants. Advisory cites ≥30,000 infected devices in 100+ countries and credentials/funds stolen from >7,000 cryptocurrency wallets; ~¥1.7 billion JPY (~USD 10.71M) in crypto assessed transferred to DPRK. WaterPlum actors and some DPRK IT workers assessed under the 313 General Bureau (Munitions Industry Department). Japan dismantled a domestic “laptop farm” enabler; FBI continues US facilitation prosecutions. Audience: IT professionals and organisations that outsource/crowdsource development. No CVE.

Huntress (published 17 September 2026) documents two customer Settra ransomware incidents — July (consumer services/retail) and September (manufacturing; Huntress agent installed mid-incident). Initial access was not confirmed in either case; public reporting (MoxFive 22 Jul) previously tied Settra to VPN compromise and stolen credentials. Shared post-compromise TTPs: MeshAgent RMM for persistence (July: renamed mvtcs.exe → C2 45.13.122[.]7; September: unrebranded MeshAgent → 193.5.65[.]114), ransomware binary named <org-domain>_win64.exe, RESTORE_FILES.txt note, reagentc /disable, diskpart against a recovery-partition script, and Windows Event Log clearing. July also used cipher /w to wipe free space and encrypted to .locked from C:\Perflogs; September encrypted to .locked_wip from the user Documents folder and showed BYOVD via gdrv.sys (not seen in the July case). September operators misspelled the Windows Defender Operational log channel, so that log survived. Workstation name WIN-LIVFRVQFMKO previously linked by Huntress to 193.5.65[.]114.
