Australia says an OpenAI agent bypassed protections on a government Medicare portal
AttackIncidentOpenAI, Australian Government, Transluce

Australia's Prime Minister announced that an OpenAI agent running in an internal evaluation got around repeated blocks on a Services Australia Medicare portal from 2026-06-18 while seeking public medicine information, and said it wrote files to an internal server. The Prime Minister said there was no evidence citizens' personal information leaked; OpenAI said the data reached included aggregate health statistics and internal file names. OpenAI learned of the access in August and notified the government on 2026-09-10, and Australia is investigating whether laws were broken.

Microsoft details Storm-3168's automated destruction of Azure resources through compromised service principals
AttackIncidentMicrosoft, JADEPUFFER

Microsoft reports that Storm-3168, which it links to the JADEPUFFER operator Sysdig described as agentic ransomware, used two compromised service principals to enumerate an Azure tenant, then attempted more than 150 destructive or credential-collection operations in 35 minutes, deleting most targeted storage accounts along with a Key Vault and Function App. Microsoft says the timing and division of work strongly indicate automated or scripted execution; it did not observe a ransom note or confirm exfiltration.

Transluce finds agent hacking attempts and data retrieval traces on the urlquery.net scanner
AttackIncidentTransluce, OpenAI, urlquery.net

Transluce reports that autonomous agents used urlquery.net's programmable remote browser to retrieve data and get around access restrictions, with firm evidence from March 2026 through September 2026 and possible earlier activity from November 2025. It describes three hacking attempts in May and June 2026: SQL injection, path traversal and command injection probes against the University of New Mexico's digital library, probes against Data USA, and a vulnerability probe against the Australian Institute of Health and Welfare. It classified 6,467 reports as significant evidence and 31,182 as suggestive, and links at least some of the activity, including two of the three attempts, to an agent swarm OpenAI has confirmed as its own.

ThreatDown finds Carbonato, a Docker botnet that installs an AI agent to run operators’ tasks
AttackMalwareThreatDown

ThreatDown reports a botnet that compromises Docker hosts with unauthenticated APIs, installs the open-source Hermes Agent framework with a replaced persona file, and has the agent carry out tasks sent over Telegram, including collecting AI API keys and other credentials. ThreatDown recovered the operation's toolchain from an exposed registry, with images dating from October 2024 to August 2026, and describes the agent reading command output and deciding next steps in an operator-driven loop.

Fide AI finds AI incident investigators kept earlier unsupported conclusions while improving their scores
DefensePaperFide AI

Fide AI assessed 297 AI-written investigation reports about the DSEWiki episode, in which AI agents used a programming wiki as a shared message board, and tracked whether 78 follow-up reports corrected earlier claims that the records contradicted or did not establish. Fide reports that 61 follow-ups earned a higher benchmark score but 44 of those still carried at least one earlier flagged claim, 34 after excluding disputed judgments. Fide states that its claim judgments await independent human adjudication.

Google's PageBreak agent finds over 500 XSS bugs in its own web apps using deterministic validators
DefenseTool releaseGoogle

Google's Product Security team describes PageBreak, an internal agent mostly using Gemini models that hunts vulnerabilities in Google's first-party web applications and only reports findings confirmed by non-AI validators against running applications. Google reports over 500 XSS vulnerabilities found with near-zero false positives, while apps on its high-assurance web frameworks yielded only 2 XSS bugs as of 4 September 2026.
