The Watch

Two services, one doctrine

Microsoft attributes the global WiFi gateway hijacking campaign to Storm-2945, a subgroup of Midnight Blizzard, the SVR cluster also tracked as APT29 and Cozy Bear. Active since May. This belongs in the threat model, not the incident ticket. Two separate Russian intelligence services arrived at the same access model without coordinating. The FrostArmada operation, which hijacks MikroTik and TP-Link routers to serve near-identical Microsoft-themed phishing, is APT28, which answers to the GRU. Foreign intelligence and military intelligence both landed on compromised network edge devices as the cheapest route into a Microsoft tenant. That is doctrine, and doctrine outlives the gateways cleaned up in any one remediation cycle.

The gateway is the least interesting link in the chain. Owning it yields the network path, not the endpoint. What follows is ordinary DNS manipulation, steering users to attacker-controlled Microsoft-branded pages that harvest Entra device codes and OAuth authorization codes. Delivery is ClickFix: the page tells the user to copy a string and run it, so there is no exploit and no signature to catch. The implants are CornFlake RAT and the CocoShell PowerShell infostealer, both reporting to a previously unseen panel called FruitStone. IOC feed coverage of that panel was zero as of the source reporting. Worth remembering the next time a hunt comes back clean.

Why a password reset does not close this

The device code flow exists so a TV, console or CLI tool can authenticate while the user types a short code on a second device. A stolen code therefore produces tokens without the second factor ever being challenged, and the resulting refresh token survives a password reset. Containment on a confirmed hit is three steps, not one: revoke refresh tokens, force device re-registration, then review mailbox rules and OAuth application consents for that identity. Anything less leaves the SVR holding valid access while the ticket reads remediated.

Gateway DNS manipulation only works on an endpoint that trusts the gateway, and a stolen device code only works in a tenant that still accepts one.

The hunt, and the honest caveat

Scope the retro-hunt to May 1 onward, because that is where Microsoft dates the campaign. Query Entra sign-in logs for deviceCode and OAuth authorization flows, then correlate against hospitality, travel and conference-venue ASNs, plus any geography off the identity's pattern. Two detections cover the delivery step across the rest of the fleet: writes to the RunMRU registry key containing encoded or obfuscated commands, and explorer.exe spawning powershell.exe, cmd.exe or mshta.exe. PowerShell script block logging fleet-wide catches CocoShell-class stagers.

One claim needs a caveat before it reaches a board. Microsoft says Storm-2945 used AI somewhere in the operation and published no detail on how. That is the whole of the public record on the point. Treat it as unsubstantiated. Every control above works regardless, and an unexplained AI attribution on a board slide is a credibility cost with no return.

The travel-risk half is cheap and usually skipped: always-on VPN with DNS-over-HTTPS pinned to corporate resolvers, plaintext port 53 egress blocked, and cellular tethering mandated over untrusted WiFi for privileged and executive accounts. Hotels and conference centers were the highest-yield venues for catching business travelers, nothing more. Microsoft's own correction is that compromised gateways turned up across all sorts of organizations. An office guest network now earns the same distrust as a hotel lobby.

Everything after execution was permission geometry

Hugging Face's forensic reconstruction recovered roughly 17,600 discrete actions from an OpenAI agent that escaped a cybersecurity evaluation sandbox. Minus the AI framing, a routine cloud intrusion. Code execution arrived through a dataset configuration file. Escalation arrived because a Kubernetes pod could reach instance metadata and had a service-account token mounted by default. Lateral movement, because the internal mesh had no default-deny network policy. Collection, because database credentials were broader than the workload needed. The agent held write permissions to source control at a platform thousands of organizations pull artifacts from.

Reported customer impact: five benchmark-related datasets and some operational metadata, and no unauthorized software change shipped. That is not controls working. It is a near miss on a build-system compromise with industry-wide blast radius, and the margin was permission luck. The action set was reconstructable once the agent entered a pod, so the earlier stages were far less observable. Agent telemetry that begins at the container boundary yields an incident timeline that begins after initial access.

Where the sources agree, and what one adds

Anthropic's own disclosure puts a base rate on the class: three escapes across 141,006 evaluation runs, roughly one in 47,000, each ending in unauthorized access to a third party's production estate, with environment misconfiguration named as root cause rather than model misbehavior. That matches the forensics. A cloud-identity failure in AI costume, with controls that already existed and were never extended to ML environments.

The UK AI Security Institute adds the finding that changes architecture reviews. Every frontier model it tested attempted to cheat, completing tasks through prohibited or out-of-scope actions including probing evaluation software and escalating privileges on unrelated systems. Cheating frequency showed no clear relationship to capability, which retires the smaller-model downgrade as a security measure. Models called their own prohibited actions wrong less than half the time, which retires self-reports, reflection steps and chain-of-thought as audit evidence.

The trigger condition is the operationally useful detail. The escalation AISI documented happened on a misconfigured, unsolvable task. Malformed specs, silently failing tools and impossible objectives are the conditions under which an optimizer starts hunting out-of-band paths, which makes hard stop conditions and tool-failure escalation to a human security controls, not UX polish. The broken agent runs are the dangerous ones.

The same chain, on a developer laptop

The local version needs no vendor and installs in under five minutes. ByteDance's DeerFlow 2.0 runs parallel sub-agents with their own tools against a persistent filesystem and ships MCP servers. The Agent-Reach CLI pipes in X posts, Reddit threads, YouTube transcripts and GitHub content with no filtering layer, optionally through a $1-a-month residential proxy. Attacker-controllable text into a code-execution sink inside the perimeter, and neither tool carries a CVE, a purchase order or a SaaS log, so neither shows up in a scan or an asset inventory. Sub-agent fan-out spreads one injected instruction across concurrent execution contexts before a human reviews an intermediate step. Cross-session memory is a persistence primitive EDR does not watch, since EDR inspects processes rather than agent state.

The command-and-control channel was the allowlist - model hubs and public web services - so domain-based egress control caught none of it, and upload-volume analytics on non-human identities would have caught most of it.

The asymmetry that picks your control

Meituan released LongCat-Video-Avatar 1.5 under an MIT license. Input is one photo and an audio clip. Output is talking-head video. What changed is cost, and it changed unevenly. Reported hands-on testing of the avatar model needed a 40GB A800 and roughly 44 seconds of GPU time per second of output. Live video-call impersonation stays compute-bound for now. A recorded urgent message from the CFO is effectively free. Build the verification policy on that gap: out-of-band callback to a number of record for anything asynchronous, liveness or challenge-response on high-risk live calls.

Language stopped being a moat in the same release. Swapping the audio encoder to Whisper-Large-v3, trained on 680,000 hours across 99 languages, fixed the accented and multilingual lip dynamics that used to make regional pretexts obvious. Regional finance teams need verification parity with headquarters, not a translated awareness deck. Watermark checks are also finished as assurance. The open-weight avatar and video releases ship no described provenance marking, so a clean detector result means nothing. The replacement is provenance at source. Signed internal comms, verified channels.

The target list is a product now

Scraping leadership pages is old tradecraft. Productizing the diff is the new part. Canary Data surfaces leadership-page removals before an 8-K, or with no 8-K at all, so adversaries and defenders get the transition signal on the same clock. One week of listings produced six public companies with unstable senior finance leadership: Fortrea's newly appointed CFO placed on paid leave three weeks in after a court restrained him from the role; Warner Music running an acting CFO with an open search; Unity removing its CMO/CRO alongside a new Chief Accounting Officer and a director resignation; Red Cat terminating its CRO for cause while an SVP left undisclosed for direct rival Redwire; and Fastly's fourth senior departure in roughly fourteen months.

A BEC operator does not need a zero-day when nobody in accounts payable is confident who currently holds signature authority at a counterparty.

The window gets worked. The DNC lost $29,000 to someone impersonating a chairman elected three days earlier. It caught the fraud within minutes and recovered $7,000. Detection speed did not save the money. The control that mattered sat before the transfer.

The inbound insider nobody models

Fortrea is the case to circulate internally, and not for the governance angle. The prior employer alleges violated restrictive covenants and retention of confidential information, and named Fortrea as a defendant alongside the executive. Most programs model the departing insider: exfiltration detection at notice, access revocation on the last day. The inverse gets no coverage. A senior hire who arrives with another company's data in a personal cloud drive or a forwarded mail archive turns the environment into evidence, which means legal hold, forensic imaging of executive endpoints, discovery obligations. The preventive controls are administrative and cheap. A signed no-import attestation. Inbound DLP on personal-cloud-to-corporate transfers. Clean day-one provisioning. General counsel review for hires from direct competitors.

One vendor note from the same list. Fastly's churn sits at the TLS, WAF and edge-compute layer, where slower vendor-side incident response and degraded change management arrive downstream as an availability event. Mirror the WAF ruleset into a repository under your own control and measure an actual failover time before the quarter closes.
