Google Gemini: first disclosed third-party system access during Irregular CTF eval (May 2026)

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.

Unit 42: AWS AgentCore Harness default shell can expose Identity vault plaintext via prompt injection

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.

Australia weighing smart-glasses ban in government workplaces; Optus reviewing store/office policy

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. Not a product CVE — workplace/privacy policy signal for AU organisations. Primary: iTnews 18 Sep (gov + Optus).

ACSC joint advisory: DPRK WaterPlum / Contagious Interview targets IT pros (crypto + laptop farms)

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).

CISA retires Weekly Vulnerability Bulletin; points defenders to KEV / BOD 26-04 risk-based patching

SecurityWeek (17 September 2026) reports that CISA has discontinued its Weekly Vulnerability Bulletin — the alphabetical product dump of newly recorded CVEs with severity/CVSS/patch fields but no exploitation context. CISA framed the change as aligning with Binding Operational Directive (BOD) 26-04 (June), which directs US federal agencies to prioritise remediation using real-world risk factors including evidence of exploitation and exposure, not severity scores alone. CISA continues risk-focused output via the Known Exploited Vulnerabilities (KEV) catalog, alerts, and advisories. Practical takeaway for AU SOCs that mirrored the bulletin: shift intake to KEV plus vendor PSIRTs / NVD / ASD-ACSC alerts rather than expecting a CISA weekly CVE dump.

N0va phishkit: US/EU business phishing abusing legitimate auth flows (ANY.RUN / THN)

The Hacker News (16 September 2026), citing ANY.RUN threat-intelligence material, describes N0va — a phishing kit targeting organisations in North America and Europe across government, technology, consulting, healthcare and related sectors. Campaigns impersonate trusted services and abuse legitimate authentication flows so successful hits yield valid account access without obvious malware. ANY.RUN publishes a characteristic URL pattern for TI Lookup: /api/verification/init?session=*&flow=*prompt_profile=. Impact once an identity is taken includes payment fraud, data exposure, and lateral move into cloud apps depending on the user’s privileges.

Windows 11 KB5124008/KB5124012: Machine Identity Isolation breaks domain trust — Microsoft workaround

Microsoft release health (Windows 11 24H2/25H2/26H1) confirms domain-joined devices can lose their secure trust relationship with Active Directory after September 2026 updates KB5124008 (24H2/25H2) or KB5124012 (26H1). Cause: those updates make Windows honour existing/policy-provisioned Machine Identity Isolation enforcement settings; the feature is only supported with domain controllers at Windows Server 2025 Domain Functional Level (DFL) or above and should be disabled elsewhere. Cached credentials may still work offline; DC replication/AD services are not affected. Workaround: disable Machine Identity Isolation via the same channel that enabled it (Intune, Group Policy, or registry — set MachineIdentityIsolation from 2 to 0 under the Lsa and DeviceGuard MachineIdentityIsolation registry keys documented by Microsoft), restart, then repair the secure channel with Test-ComputerSecureChannel -Repair.

Apple Reference Image: opt-in verified photography mode for iPhone 18 Pro (SEAR blog)

Apple Security Engineering and Architecture (SEAR) with Camera & Photos (blog 15 September 2026) introduce Apple Reference Image, an opt-in camera mode that creates a securely timestamped reference image reflecting what the iPhone camera sensor captured, aimed at distinguishing real photographs from AI-generated or heavily altered images. Apple contrasts the approach with C2PA-style post-capture provenance metadata, arguing those chains can be compromised in editing and can create privacy risks by tying images to device or personal identity. The mode debuts on the main camera sensor of iPhone 18 Pro and iPhone 18 Pro Max, using dedicated secure hardware on device and Private Cloud Compute for verifiable algorithmic steps without Apple seeing the image content.

OpenAI Codex sandbox: Overpatch + Heapjack escapes (reported 12 Aug; fixed in eight days)

Accomplish / Boundary-Bench researchers (public write-up dated 15 September 2026) disclosed two escapes from the OpenAI Codex agent sandbox, reported to OpenAI on 12 August 2026 and fixed within eight days. Overpatch (Codex CLI, open-source harness): the apply_patch tool grants write access to the parent of each path named in a patch; including a no-op path under /tmp widens the grant to /, so a crafted patch can append to ~/.zshrc (via symlink) without an approval prompt in normal agent/workspace-write mode, then run unsandboxed on the next shell. Heapjack (Codex Desktop): install writes an [mcp_servers.node_repl] block into ~/.codex/config.toml (no opt-out), spawning a Node REPL with trusted and untrusted V8 contexts sharing one heap; the trusted-context token was readable from the shared heap, enabling unsandboxed command execution even from read-only mode.

DDRop: active DDR5 interposer breaks Intel TDX / AMD SEV-SNP memory freshness

The Hacker News (14 September 2026) summarises academic/industry research (KU Leuven, ETH Zurich, Durham University, Google; ACM CCS 2026) on DDRop, an active DDR5 memory-bus interposer that silently drops writes so encrypted confidential-computing memory stays stale without integrity alarms. Targets Intel TDX (including Scalable SGX) and AMD SEV-SNP as used on major clouds; researchers demonstrated stronger outcomes on Intel TDX default logical-integrity mode (mapping, plaintext debug copy, attestation forgery) and a narrower page-copy result on AMD SEV-SNP. Requires prior software control of the host plus brief physical access to fit a ~US$159-parts interposer; researchers report no evidence of in-the-wild use. Intel and AMD treat physical interposer attacks as outside published threat models; Intel indicated it does not plan a CVE for this class of attack. No simple firmware patch: durable fix needs hardware freshness; optional Intel cryptographic-integrity mode blocks some TDX variants. Wire-only pending vendor bulletins.
