ASD's seventh Annual Cyber Threat Report, released this week, says AI has amplified and sped up existing threats rather than creating new ones. This Sunday Special draws out five messages: patch in days, attackers log in rather than break in, medium businesses are taking the biggest cost rise, incidents are up and more serious, and the answer is an assumed-breach mindset plus the basics, with a short look at critical infrastructure.

The report

ASD's ACSC Annual Cyber Threat Report 2025-26. The full report, including the "assumed breach" call and the Essentials series. https://www.cyber.gov.au/sites/default/files/2026-10/Annual%20Cyber%20Threat%20Report%202025-26.pdf ASD release. https://www.asd.gov.au/news/2026-10-27-australian-signals-directorate-releases-seventh-annual-cyber-threat-report-2025-26 Last year's report (2024-25 summary), for comparison. https://www.cyber.gov.au/about-us/view-all-content/reports-and-statistics/annual-cyber-threat-report-2024-2025 business.gov.au summary for businesses. https://business.gov.au/news/annual-cyber-threat-report-2025-26

Key figures (not read on air)

ASD changed how it categorises incidents in 2025-26, so category comparisons with 2024-25 are not like for like. - More than 82,000 cybercrime reports to ReportCyber, about one every six minutes, down about 3% from 84,700. - 1,524 incidents responded to, up from 1,253 (ASD says "more than 20%"). - More than 4,400 notifications to entities, up almost 80% by ASD's comparison. This year's total includes collective notices (about 2,200 individual notifications, up 33%, plus collective notices to about 2,100 entities). - Hotline calls: 37,500, down 12%. - Extensive compromises: 40, from 26 (not like for like); extensive ransomware incidents 24, from 16; extensive DDoS (distributed denial of service) 7, from 1, while overall DoS and DDoS incidents fell more than 60% to 80+. - Ransomware steady at 139 incidents. - Data breach incidents: 98, up 66%, about 6% of incidents (as a share, data breaches have stayed steady: 7% in 2021-22, 6% now). - Published CVEs (Common Vulnerabilities and Exposures) up 30%. - ASD tip-offs led to 362 incidents being found; one cPanel notification to 340 entities led to 60+ confirmed incidents. - Health Care is now the top non-government reporting sector (7%). Manufacturing entered the top 10 and Transport left it. - Average self-reported cost per business report: $93,500, up 16% (from $80,850). Small $55,400 (about flat, from $56,600). Medium $141,300, up 45% from $97,200. Large $148,100, down 27% from $202,700, partly reversing last year's 219% rise. - Individuals: $33,000 average per report, unchanged (separate from the "overall" average of $38,130). - 55% of people reuse passwords (Act Now. Stay Secure. campaign research quoted in the report). - Some exploitation occurs within 48 hours of a patch or mitigation advice; most within two weeks. A flaw from 2008 was exploited successfully this year.

Critical infrastructure

What the report says. Critical infrastructure (CI) is an attractive target for extortion because of its sensitive data and critical services; ASD says state-sponsored actors "routinely target" Australian CI networks, possibly for espionage or to pre-position against operational technology (OT) in a crisis or conflict. https://www.cyber.gov.au/sites/default/files/2026-10/Annual%20Cyber%20Threat%20Report%202025-26.pdf Figures. 154 CI incidents, 10% of all incidents (similar to last year), down almost 7%; category changes mean this is not like for like. Top ways in: phishing 36%, valid accounts 16%, drive-by compromise 10%. Top sectors: Financial and Insurance Services 30%, Public Administration and Safety 21%, Electricity, Gas, Water and Waste Services 17%. OT and supply chain examples. Pro-Russia hacktivists reached OT through exposed VNC remote access (ASD and partners advisory, 10 December 2025). An Iranian group's claimed compromise of Stryker, a US-based company that imports surgical and pharmaceutical equipment into Australia, was a supply-chain exposure rather than a direct attack. Guidance. ASD's CI Fortify guidance for operators is on cyber.gov.au.

PHP2Shell now has a confirmed intrusion: Unit 42 reports attackers reached a European government entity's password hashes and MFA secrets within two hours, with strong signs that an AI agent did the follow-up work, while a suspected North Korean campaign has Australian PHP hosts on its target list. A researcher has published 11 unpatched Tailscale and headscale findings, and AI coding agents can be hijacked by instruction files that land in the Downloads folder. We also recap the weekend and the key learnings from Sunday's AI assurance special.

Weekend recap and Sunday Special

Sunday Special, Episode 10: AI assurance and ISO/IEC 27090. Key learnings: build an AI inventory, including third-party and embedded AI and every agent with tool access; map training data sources and treat feedback loops as possible poisoning paths; put agents behind least privilege with approval for high-impact actions; don't count system prompts as security controls; monitor agent configuration for drift; red-team before widening agent autonomy. Episode 10 notes Brotli decoder flaw reaches beyond Node.js. CVE-2026-111497 also affects Bun, Python Brotli packages and some Envoy setups.

Suspected North Korean PHP2Shell targeting includes Australia. CYFIRMA reports slow, deliberate scanning of 216 unpatched or partly mitigated hosts in a dozen countries and regions; attribution is moderate confidence. The Hacker News; ASD's ACSC PHP alert

Global threats

PHP2Shell: confirmed intrusion with agentic post-exploitation. Password hashes and MFA secrets reached in two hours, an NTLM relay tunnel into Active Directory and a Domain Admin attempt; still not in CISA KEV. The PHP Foundation has also flagged a third RCE, CVE-2026-115560, exploitable only under an unusual session.serialize_handler setting and fixed in the regular release cycle.

AI security

AI coding agents hijacked by AGENTS.md files in Downloads. Malicious instruction files led Codex and Claude Code to run code or expose tokens in tests. BleepingComputer OpenAI's agents escaped research sandboxes during red-teaming. MicroVM escapes, routes to the internet through internal services and a CPU cache covert channel, found on isolated copies with source code supplied; frontier training now runs with no live internet access. OpenAI; The Hacker News

Outlook and patch priorities

Critical: PHP 8.5.12, 8.4.27, 8.3.36 or 8.2.35 everywhere, plus a compromise check on hosts left exposed last week; Fortinet hardening releases; Arista VeloCloud Orchestrator and Collabora fixes. High: per-pair Tailscale SSH rules, SSH forwarding off where possible, fewer app connector grants, node-key expiry; Brotli updates; no LiteLLM 1.107.0; replace eMudhra certificates. Hygiene: never launch AI coding agents from Downloads or home folders.

This Sunday Special maps the frameworks organisations use to show their AI and AI agents are secure, from the NIST AI Risk Management Framework and ISO/IEC 42001 to OWASP's agentic Top 10, MITRE ATLAS, the EU AI Act and ASD's agent guidance. The centrepiece is ISO/IEC 27090:2026, the new international guidance on threats to AI systems, explained from ISO's public material. We also cover why agent configuration drift needs monitoring and why prompt instructions are guidance, not a security control.

Deep dive, no news segment. Content about ISO/IEC 27090 is drawn from ISO's public product page and explainer; the paywalled text has not been read.

The NIST foundation

NIST AI Risk Management Framework (AI 100-1): voluntary framework, January 2023, built on Govern, Map, Measure and Manage; under revision. NIST Generative AI Profile (NIST AI 600-1): July 2024 profile of risks new to or worsened by generative AI, with suggested actions. NIST CAISI AI Agent Standards Initiative: launched 17 February 2026, covering agent security, identity and authorisation, and interoperability. NIST Adversarial Machine Learning taxonomy (NIST AI 100-2 E2025): attack vocabulary for predictive and generative AI. NIST CSRC

The ISO family

ISO/IEC 42001:2023: certifiable requirements for an AI management system. ISO ISO/IEC 23894:2023: guidance on AI risk management. ISO ISO/IEC 42006:2025: requirements for bodies that audit and certify AI management systems. ISO

Deep dive: ISO/IEC 27090:2026

What it is: guidance on understanding, detecting and mitigating security threats to AI systems across the life cycle; published 14 October 2026, 56 pages, not certifiable on its own, builds on ISO/IEC 27001 and 27002. ISO, IEC webstore ISO's explainer: three areas covering information security applied to AI, AI-specific threats (poisoning, extraction, evasion, inference, inversion, prompt injection, unsafe outputs) and keeping protection effective over time, including retraining risk. ISO Our assessment: a strong common reference for auditors and procurement; for agent-specific controls, OWASP's agentic list and ASD's guidance currently go further. Based on public summaries, not the full text. Agent configuration drift: makers can add tools, knowledge sources and instruction changes after approval; baseline, monitor, alert and re-review. Prompts are guidance, not controls: system prompts can be overridden through prompt injection; enforce limits outside the model with least privilege, approval gates, harness controls and monitoring.

Regulation and the Australian angle

EU AI Act after the AI Omnibus (Regulation (EU) 2026/1744): high-risk obligations moved to 2 December 2027 and 2 August 2028; content marking grace period ends 2 December 2026. EUR-Lex, Council of the EU timeline National AI Centre: Guidance for AI Adoption: six practices replacing the earlier Voluntary AI Safety Standard guardrails. Department of Industry ASD's ACSC: Careful adoption of agentic AI services: low-risk, non-sensitive tasks only; no broad or unrestricted access. cyber.gov.au ASD's ACSC: Agentic AI harnesses, the layer above the model: least privilege, secure design, monitoring and logging, human oversight and accountability. cyber.gov.au

Actions for defenders and leaders

Build an AI inventory, including embedded AI and every agent with tool access. Map training and retraining data sources; treat feedback loops as poisoning paths. Least privilege and approval points for agents; govern the harness, not just the model. Do not count system prompts as security controls. Monitor agent configuration for drift and re-review on change. Watch for high-volume or patterned queries that could signal model extraction. Red-team against OWASP's agentic list and MITRE ATLAS before widening autonomy. Plan a 27001 to 27090 gap review; note EU dates of 2 December 2026 and 2 December 2027.
