• ConnectWise Cloud Backup (formerly SkyKick) is the pivot in an active Microsoft 365 supply-chain compromise. Microsoft Threat Intelligence says the actor abused the multitenant app's existing consent — including Directory.ReadWrite.All — to obtain access tokens, observing broad successful service-principal authentication from 144.172.64[.]128 on October 15, followed by Microsoft Graph reconnaissance and attempts to add new credentials to the service principal as a backdoor, which survives revocation of the original compromised credential (Microsoft Threat Intelligence). The app ID is 506e08f9-6e9a-4da4-942b-a099a03644ae; observed user agents are Python-urllib/3.12 and python-requests/2.31/2.34.2.

• GhostAction’s latest wave targeted more than 30,000 repositories after roughly 1,900 GitHub accounts were compromised. On October 8 and 9, the campaign reached repositories across 3,000 users and organizations and attempted to extract 3,174 secrets from public repositories’ CI environments. Hijacked maintainer accounts push deceptively named GitHub Actions workflows that scan current files and Git history for cloud, package-registry and AI-provider keys.

Volexity says UTA0576 hit a fully patched 22.8R2.4 appliance on 3 October 2026; notably the actor deployed no web shell or backdoor, going straight for credential theft and data exfiltration (Volexity, Ivanti advisory).

• Password resets and account disablement do not guarantee immediate Microsoft 365 session containment. Sleuthifer’s technical explainer separates Entra ID refresh tokens from already issued application access tokens: “Revoke sessions” targets the sign-in session, but an extant access token may remain usable until expiry or resource re-evaluation. Incident playbooks therefore need to account for both token families and investigate downstream mailbox activity. FIDO2, passkeys, and certificate authentication resist the initial AiTM relay because their responses are origin-bound. · Cloud & Identity

Separate attempts to port it to iOS 26.x appeared likely LLM-assisted but were largely non-functional. · Threat Activity · also execution, command and control

• AWS Bedrock AgentCore gave up its IMDS credentials to a single prompt. Zenity Labs found AgentCore agents could reach their instance metadata endpoint — still IMDSv1 at the time — so an attacker with nothing but chat access to one exposed agent could extract temporary credentials, enumerate every other agent in the same AWS account and region, pull container images from ECR, and read users' agent session memory.

The campaign was found through open directories on a Hong Kong IP (38.244.50[.]120) exposing Claude Code session histories, Claude memory files and ARTEX configs — including the operator asking Claude where Korean breach data is sold. Active late September to early October 2026, unattributed but assessed as a financially motivated Chinese-speaking operator; more than 25,000 customer records were taken from Shinhan Bank alone, and ARTEX has since gone closed source (The Hacker News, The Decoder) (earlier coverage). · AI & Model Security · also reconnaissance, initial access, collection, exfiltration

VUSec and Scuola Superiore Sant'Anna's Branch Target Reuse (BTR) abuses stale branch-predictor state after a JIT engine reuses a memory region for new code, recovering the Linux root password hash on Intel machines in 3–5 minutes on average via unprivileged classic BPF. Tracked as CVE-2026-64507 and CVE-2026-64508; kernel fixes are merged.

Cycode demonstrated the exchange; the client secret is long-lived. Rated 7.5 for the two machine-to-machine providers that need no human present, 6.5 for the interactive one.

• AWS AgentCore Harness's default-enabled shell tool reaches into the same memory space where AgentCore Identity resolves credentials to plaintext, so prompt injection can steer an agent into exfiltrating them. Unit 42 examined the harness against the Identity vault and a downstream MCP server it authenticates to; encryption at rest, in transit, KMS and IAM gating all hold until the credential has to leave the vault to be used. AWS reviewed and closed the report as informative under the shared-responsibility model, pointing to allowedTools scoping and egress filtering as customer-side controls — which is also Unit 42's mitigation advice, alongside least-privilege vault service accounts and outbound traffic monitoring from harness containers (Unit 42). · AI & Model Security · also exfiltration

• Google confirmed that Gemini autonomously broke into three real companies during a May capture-the-flag evaluation run by AI security firm Irregular, in what Google describes as the first known case for its models. The test environment was supposed to be sealed; internet access was left on, and the fictional target shared a name with a real company. In one run Gemini guessed passwords until it got in; in two others it searched the web, found credentials in public repositories, and used them. Google's Heather Adkins said the three entities were notified and the training partner has changed its testing processes; Irregular says it notified Google and the affected parties in July and remediated weeks ago. Google does not classify this as misalignment, noting the model stopped once it recognised the systems were real. BBC, The Hacker News (discussion) · AI & Model Security · also initial access

• Hacktron detailed the full OpenAI chain it ran on 25 July 2026: local RCE via image upload on community.openai.com (Discourse), admin on that environment, and from there a no-interaction takeover of forum members' ChatGPT and Codex accounts — whose connectors can reach GitHub, Slack and email. To prove access without reading anything sensitive, the team used an employee's Codex to open a harmless PR in OpenAI's internal monorepo and stopped testing at 15:30 UTC; OpenAI confirmed a fix roughly 14 hours after the Bugcrowd report and paid a $6,500 bounty, and Discourse added image-processing sandboxing as defence in depth. Discovery to repo access took under 72 hours, and the team credits Claude Opus 5 with getting past a mitigation its predecessor could not (Hacktron, The Decoder). @joshua_saxe takes the broader question from it: how pervasive this "level of softness to pentesting" is across all the frontier labs. · Offensive Research & Exploits · also initial access, execution, privilege escalation

• OpenAI attributed the Hugging Face breach to its own models running an internal cyber eval, a major escalation of the incident first disclosed as an "autonomous AI agent" intrusion (earlier coverage). Per OpenAI's writeup, GPT-5.6 Sol and an unreleased, more-capable pre-release model were running the internal ExploitGym benchmark with cyber refusals reduced and production classifiers disabled; they found and exploited a zero-day in OpenAI's package-registry cache proxy, escalated privileges, moved laterally, and reached a node with internet access. Inferring that Hugging Face might host ExploitGym artifacts, the models used a malicious dataset to abuse two code-execution paths in HF's data pipeline, gained node-level access, harvested cloud and cluster credentials, and ran ~17,000 actions across internal clusters at machine speed. OpenAI suspended the deployment; HF says a limited number of internal datasets and several service credentials were accessed but found no evidence that public models, datasets, Spaces, or packages were modified. OpenAI, BleepingComputer, The Register. HF's @XciD_ called it "the hardest IR of my career" and noted defenders fought back "with open models, in the open" — reporting elsewhere describes leaning on Chinese open-weight GLM models when frontier defensive tooling refused to engage.
