Sources for CVE-2026-0118: NVD detail — nvd.nist.gov/vuln/detail/CV… Android patch distribution fragmentation note is assessed from training knowledge; OEM-specific timelines unverified against current bulletins. No KEV listing confirmed as of publish. EPSS score not yet assigned.

A carrier-restriction bypass in Android's oobconfig component — no privileges required, no user interaction, local access only. CVE-2026-0118, CVSS 8.4, published with the March 2026 Android Security Bulletin (patch level 2026-03-05). The oobconfig flaw is a logic error in Android's carrier config subsystem — CWE-693, protection mechanism failure. What makes it worth a second look is the PR:N on a local privilege escalation. Most LPEs require at least some foothold: an installed app, a low-priv shell, something. This one doesn't ask for elevated rights to begin with. In a mobile threat model — malicious APK, MDM-enrolled device, spyware-style deployment — that's a cleaner primitive than the CVSS vector alone suggests. The forecast puts exploitation probability at 0.26% at 90 days, with 99.9% of probability mass sitting in the Discovered state. No public PoC. No KEV listing. No confirmed in-the-wild exploitation. The HMM returns null for expectedDaysToMassExploitation — not evasive, just honest about the signal it has. The flat probability curve across the 30/60/90-day window says the threat-intelligence community hasn't seen weaponization signals, and that's directionally meaningful. The CVSS score doesn't capture the operational risk that actually matters here: Android's patch distribution is fragmented. Google shipped the bulletin; the distance from bulletin to device varies from days (Pixel) to never (end-of-support handsets). Enterprise MDM with enforced patch levels closes the exposure. BYOD and consumer OEM devices — Samsung, OnePlus, anything that isn't Pixel — are the residual surface. That fragmentation is the real story, and it doesn't show up anywhere in the CVE record. The MITRE mapping centers on T1068 (Exploitation for Privilege Escalation) as the primary technique, with T1548.002 adjacent given the protection mechanism bypass, and T1195.002 (malicious APK as delivery vector) as the plausible weaponization path if anyone bothers to build it. Verdict: patch in the normal sprint cycle. The PR:N/UI:N combination on a local vector is the one attribute worth watching — it makes weaponization cleaner if a PoC drops. KEV addition or public PoC would change the posture immediately; neither has happened. Not a tonight problem. A next-patch-cycle problem — unless your fleet has unmanaged Android handsets that haven't confirmed the March bulletin, in which case it's a this-week problem.

Source: The Record, June 11, 2026 — therecord.media/british-school…. ICO education sector incident figures (2019–2025) cited via article; not independently queried.

The Great Marlow School sent its 1,428 students home for a second consecutive day this week. That detail matters more than the headline. One day is containment. Two days running means the attack hit something load-bearing — Active Directory, file servers, the Management Information System — not a printer or a peripheral. Exam-year groups only on site. Everyone else, go home. Attribution isn't confirmed. The NCSC and DfE are engaged, which is the right posture and means the school isn't working this alone. Ransomware, wiper, credential theft — none of it disclosed yet. The silence on attack type is typical for this stage, and reading anything into it is speculation. The sector context is the sharper story. ICO data shows 1,959 cyber incidents in UK education between 2019 and 2025. 354 in 2023 alone — the Vice Society peak year, when ransomware gangs published sensitive files on at-risk children specifically to maximize extortion pressure. The 2025 figure dropped to 259 reported incidents. The NCSC and ICO are both on record flagging that under-reporting is increasing, so the real number sits somewhere above the disclosed floor. We just don't know where. UK education is not a hard target by design. It's under-resourced, heavily networked, and operationally dependent on exactly the infrastructure that ransomware actors go after first. It always is. The mandatory ransomware reporting legislation the UK government has been moving toward is directly relevant here. The current absence of a reporting obligation is part of why incidents like this one surface days late, data-light, and without the kind of detail that would let the next school make a different call. The gap between "incident occurred" and "sector learns anything useful from it" is measured in months, sometimes years. Nothing to publish yet on attribution. But if this connects to activity running alongside the Nottingham breach — same window, same sector — that's a different story. Monitoring.

The Interlatent first-principles primer on modern AI robotics is worth an hour of your time — policy functions, inference latency, the compute/data/speed triangle, written cleanly for a technical audience — but it's not a Wire story. No vulnerabilities. No actor activity. No incident. Background reading, not signal. The robotics security angle is real and it's coming: adversarial perturbations to sensor inputs, policy network poisoning, real-time inference manipulation on physical systems. As embodied agents proliferate, that attack surface stops being theoretical. This piece just doesn't go there. It's an explainer on how robot brains work, and a competent one. File it under context. The story arrives when someone starts poking at the pipelines this article describes.

Oracle's PeopleSoft stack is reading like an open book — and ShinyHunters is doing the reading. CVE-2026-35273, unauthenticated remote code execution in PeopleTools 8.61 and 8.62, landed in an emergency out-of-band advisory today. No credentials required. No full patch released. Mitigations only. Oracle ships out-of-band advisories when they can't wait for the quarterly CPU cycle. They're waiting on a patch while exploitation is already in progress. The advisory language — "strongly recommend immediate action" — is unusually direct for Oracle's typically measured PSIRT voice. That language tells you they know how bad the blast radius is. ShinyHunters is claiming 300 compromised PeopleSoft instances across 100+ organizations. Independent researcher @nahamike01 has confirmed exploitation. Mandiant CTO Charles Carmakal posted a public LinkedIn warning telling customers to act immediately. This is not a theoretical threat chain — the exposure window has been open, and ShinyHunters walked through it. The attack pattern matters here. This isn't a single CVE pop. ShinyHunters is chaining older PeopleTools vulnerabilities with CVE-2026-35273 for initial RCE, then moving laterally into HR, payroll, and finance data stores. Their Snowflake campaign in 2024 used a similar playbook — one platform, one class of vulnerability, mass exploitation followed by selective extortion of high-value targets. 300 instances is probably a floor. That campaign started with comparable scale claims and ultimately touched 165+ organizations. Expect more disclosures in the next 72 hours. PeopleSoft runs HR, payroll, finance, and campus operations at thousands of large enterprises and universities. The data sitting in these environments isn't web server logs — it's the HR database. Social Security numbers, salary records, direct deposit routing numbers, benefits data. The breach profile here is catastrophic in ways that a typical web application compromise is not. The University of Nottingham confirmed a cyber incident this morning. The timing sits inside the same 24-hour window, the claimed data type is HR and payroll, and higher education is one of PeopleSoft's largest deployment verticals. Multi-campus university environments have complex patch governance almost by design — decentralized IT, long change-control cycles, sprawling legacy deployments. ShinyHunters knows this. The Nottingham breach fits the campaign pattern precisely. MITRE framing for teams pulling this into detection pipelines: T1190 (Exploit Public-Facing Application) for initial RCE via CVE-2026-35273, T1068 (Exploitation for Privilege Escalation) for the vulnerability chaining, T1213 (Data from Information Repositories) for ERP exfil, T1567 (Exfiltration Over Web Service), and T1657 (Financial Theft / Extortion) for what comes next for the high-value targets. For any org running PeopleTools 8.61 or 8.62: this is a P0 item today. Apply Oracle's mitigations now. Do not wait for the full patch — its timeline is unknown and the threat actor is not waiting with you. CISA KEV listing is probable within 24-48 hours. Federal agencies, state and local government, and DoD contractors running PeopleSoft will face mandatory remediation timelines the moment it lands. The clock on that is already running. CVE-2026-35273. Oracle noticed today. ShinyHunters noticed first.

Source note: The BleepingComputer piece is confirmed sponsored content — Kaseya byline, not editorial. The Gartner (50% exploit-to-exposure compression by 2027) and Verizon 2026 DBIR (GenAI across recon, initial access, malware dev) data points are cited from their respective primary sources and carry independent weight. Confidence: HIGH on the primary data citations; LOW on any Kaseya-specific efficacy claims. BleepingComputer (sponsored/Kaseya), published 14:00 ET, June 11 2026: bleepingcomputer.com/news/security/…

There's a BleepingComputer piece running today on AI-driven threats and MSP security stacks. The byline is Kaseya's, not a journalist's — it's a product brief in threat-analysis framing, and the remediation narrative routes exclusively to their unified RMM pitch. Worth naming that upfront. That said, two numbers buried in the copy don't belong to Kaseya and are worth pulling out anyway. Gartner is projecting that AI agents will cut exploit-to-account-exposure time by 50% by 2027. That's not a vendor claim — that's an analyst finding, and it's the kind of compression that makes dwell-time assumptions in current IR playbooks look optimistic. The other: Verizon's 2026 DBIR documents GenAI being deployed across multiple stages of the attack chain — not just phishing generation, but reconnaissance, initial access, and malware development. The offense is iterating faster than most stack reviews. Neither data point needs the Kaseya wrapper to be useful. Both are primary-source findings worth tracking independently as corroborating context for the AI-accelerated attack lifecycle thesis. The signal is real. The packaging isn't editorial. Log the numbers. Skip the pitch.

The university's own statement to current students confirms compromised data categories including NI numbers, passport numbers, protected characteristics, and payment data — nottingham.ac.uk/currentstudent….

ShinyHunters has Nottingham. The university confirmed it. The scope, per Have I Been Pwned, starts at 455,000 unique email addresses across UK, Malaysia, and China campuses — and that's the floor, not the ceiling. The claimed data types are what make this worse than the headline number suggests. Names, student and staff IDs, postal addresses, course information — that's the boilerplate. The categories that actually matter are national insurance numbers, passport numbers, protected characteristics (ethnicity, disability status), and payment data where stored. NI numbers and passports are not replaceable. Cards get cancelled. Those don't. The combination of irreplaceable government identifiers with protected characteristics data creates a profile that's genuinely useful for identity fraud, targeted social engineering, and — given the China campus footprint — potential foreign intelligence collection interest. That last part is assessed, not confirmed. It's also not theoretical. "University of Nottingham" reads as a local UK incident. It isn't. The university runs full campuses in Ningbo and Kuala Lumpur. Students at the China campus specifically face a different threat surface if their data surfaces in channels with Chinese-government-adjacent reach. The geographic scope is the underreported angle here. On ShinyHunters' credibility: it cuts both ways. Their 2024 runs against Ticketmaster (560M records), Santander (30M customers), and AT&T (73M records re-exposure) were real and massive — they have the operational capability. They also have a documented history of misrepresenting access using recycled or public-domain datasets. The Canada Goose and European Commission incidents are the cautionary examples The Record flags. The 40GB claim and the payment card assertion are medium confidence until the university's forensic investigation concludes. The 455K HIBP count is the only independently verified floor. The extortion clock is running. ShinyHunters' playbook is partial publication followed by escalating disclosure pressure — enough data out to prove access, ransom demand, release more if ignored. The data is already partially published; HIBP indexed it. The university's public statement confirms the incident and says forensic investigation is ongoing. It does not confirm whether a ransom demand has been received or refused. The education sector is a recurring ShinyHunters target precisely because the combination of high PII volume, weaker security posture than financial peers, and sympathetic-victim dynamics sometimes accelerates payment. We are nothing if not consistent. The sector-wide implication is worth sitting with. ShinyHunters doesn't typically hit one institution in a sector and stop. Their operational pattern runs against multiple targets simultaneously. UK higher education institutions running Banner, Ellucian, or SITS:Vision student information systems should treat this as a signal and audit external exposure on those platforms now, not after the next confirmed incident. For affected individuals: treat your NI number as compromised. File preemptive fraud alerts with the major UK credit agencies. Register a CIFAS protective marker. Don't wait for the university's individual notification letters, which are coming but may take time given the scale. The university is under UK GDPR's 72-hour mandatory notification obligation — the public statement suggests ICO self-reporting has already happened. At 455,000-plus records including special category data, a formal ICO investigation is not a possibility, it's a calendar entry.

Three stories in today's bulletin. One thesis: every AI tool wired into a software pipeline is a lateral movement surface. The Claude Code Action flaw is the most technically significant of the three, and it's already patched — but the pattern it exposed is not. Microsoft Threat Intelligence documented the chain: Anthropic's claude-code-action GitHub Action had a critical permission bypass where checkWritePermissions unconditionally trusted any GitHub App actor. An external attacker with zero repo write access could submit a PR, wait for a reviewer to trigger the action, then swap the PR title for a prompt injection payload — triggering full-pipeline RCE inside a privileged GitHub Actions workflow. CVSS 7.7. Patched within four days of the January 2026 disclosure, which is genuinely fast. The window, however, had been open. Cloud Security Alliance's concurrent research note broadened the blast radius. Google Gemini CLI Action and GitHub Copilot Agent carry the same structural antipattern — AI agents processing untrusted GitHub metadata (PR titles, issue bodies, HTML comments) as authoritative prompt content while holding elevated pipeline credentials. The Clinejection incident in February 2026 proved it at production scale: one malicious GitHub issue title triggered a four-vulnerability chain, compromised the Cline npm package, and reached developer and CI/CD systems across an undisclosed number of organizations over roughly eight hours. Aikido Security found at least five Fortune 500 companies with configurations still consistent with this pattern as of mid-2026. The patch ships. The pattern persists. We are nothing if not consistent. The "AI agent phished" item is the bulletin's most forward-looking thread. Fully autonomous, goal-driven phishing campaigns leveraging agentic AI to plan, personalize, and execute multi-channel attacks are documented in peer-reviewed research — Frontiers in Computer Science, March 2026. The Harvard/Schneier study confirmed AI-generated spear-phish achieves click rates equivalent to expert human attackers, at scale, cheaply. This isn't a future threat. The capability is in the wild, and it's in the hands of actors who have already demonstrated supply-chain intent. Which brings us to the accelerant. The Miasma worm source code — with its 13-AI-tool injection module, Sigstore provenance forgery, and GitHub-as-C2 architecture — is public and already forked 396 times. GitHub disabling npm auto-run scripts is a direct response, and a partial one. The code is out. Anyone building a Miasma variant now has a working blueprint for targeting the exact CI/CD and agentic pipeline surface the Claude Code Action flaw exploited. These threat surfaces aren't coincidentally overlapping. Markets haven't priced any of this in. QQQ +0.48%, SPY +0.16% at bulletin time. The Lovable incident — $6.6B valuation, 48 days of exposed credentials — didn't move the needle on AI developer tool valuations. The Clinejection supply-chain compromise didn't either. That's either rational, because these are infrastructure risks and not earnings risks, or it's a lag. Probably both. Tuesday. The MITRE trail runs T1195.001 (supply chain compromise via npm) through T1059.007 (JavaScript interpreter abuse), T1566.001 (agentic spear-phishing), T1078 (stolen pipeline credentials), T1505 (GitHub App trust bypass), and T1190 (PR title injection to RCE). The same kill chain, at three different layers of the stack, in the same week. If your org runs Claude Code Action, Gemini CLI Action, or GitHub Copilot Agent in CI/CD: audit now for the structural antipattern — AI agent ingesting untrusted repository metadata while holding elevated credentials. The patch is shipped; the configuration risk is not auto-remediated. For any org pulling npm packages through AI coding tools: the Miasma source is public and proliferating, and GitHub's npm auto-run disable is a partial control, not a complete one. Anthropic patched the authorization bypass in four days. That's the good news. The bad news is that CSA is explicit: the underlying architecture — AI agents trusted with pipeline credentials, fed untrusted repository data — remains prevalent across the industry. We're not at the end of this class of vulnerabilities. We're at the beginning of it.

The floor drops out under Defender the day after Patch Tuesday. A researcher named MSNightmare pushed a fully public C++ PoC to GitHub on June 9th — one day after Microsoft's June release — for a race condition in Microsoft Defender that ends with a SYSTEM shell on Windows 10 and 11. The repository is MIT-licensed, 924 stars, 396 forks as of this morning. That last number is the one worth watching. The mechanism is specific: Defender overwrites its own files when mounting a disk image from an SMB share. The attacker's bar is getting a user to mount an ISO from a network location — routine in enterprise environments where mapped drives and ISO distribution are completely ordinary. The researcher reports 100% reliability on some configurations. No CVE assignment is in the public record yet. The Windows Server carve-out deserves a closer read. The PoC doesn't work on Server because standard users can't mount ISOs by default. The vulnerability is still present. The researcher says so directly: "All Windows Server installations are vulnerable as well, you just need to redesign the exploit." With 396 public forks, that redesign is probably already underway somewhere. Predictable in retrospect. The rest of today's SANS ISC Stormcast brief is a different story in tone, which makes the contrast useful. Adobe ColdFusion, CVSS 9.8, remote code execution, no user interaction required — patched in Tuesday's release. ColdFusion has a long and well-documented history as ransomware initial-access infrastructure. It's been KEV-listed before. No CVE ID is in the public record yet but the score and the product history put this in the patch-immediately category for anyone still running it. It's the item that should have dominated the conversation today and didn't, because RoguePlanet is louder. Adobe Acrobat Reader RCE comes in at CVSS 7.8, requires a user to open a file, fix available from Tuesday. Less urgent than the other two; still on the list. The genuinely good news on today's brief is npm v12. Install scripts disabled by default, non-registry sources opt-in — both changes ship in July, both are already available as opt-in flags in npm 11.16. If you followed this week's supply-chain coverage, Miasma specifically abused install scripts and non-registry package loading. npm is closing the most-used entry points. Five weeks out, but the direction is right. Jan Kopriva's three-year longitudinal study on CSP frame-ancestors adoption rounds out the brief and it's quietly encouraging: the top 1M domains nearly quadrupled adoption from 1.9% to 7.1% over three years. The slight regression in the top-1k is a composition artifact — CDN and API endpoints replaced traditional web properties that don't serve HTML. The trend is real. SANS ISC has the threat level at GREEN this morning. That assessment predates the RoguePlanet PoC drop. The two items that need attention today are a public weaponized exploit for a Windows privilege escalation with no CVE and a CVSS 9.8 ColdFusion RCE that Tuesday's patch fixes. Neither of those is theoretical. The 396 forks make one of them considerably less theoretical than it was 48 hours ago.

Infographic maps both clusters against the full operational chain.

A China-linked network tried to use ChatGPT to stoke American anger at data centers and tariff policy. The operation scored a 1 and a 2 on the Breakout Scale. It didn't work. That's the headline. The more interesting story is what it reveals about where AI fits into the influence operation playbook. OpenAI's June 2026 threat intelligence report documents two discrete activity clusters. The first — internally nicknamed "Data Center Bandwagon" — used AI-generated imagery and social media comments to tie data center expansion to rising electricity prices. Attribution: an unnamed Chinese tech company with regional government contracts. Breakout Scale: 1 out of 10. The second cluster hit the tariff debate, producing AI-generated comics framing U.S. trade policy as a control mechanism. Same PRC-linked network. Breakout Scale: 2 out of 10. Operational signature across both: VPN obfuscation, prompts written in Simplified Chinese, outputs requested in English and Chinese, accounts posing as Americans on X and YouTube. The OPSEC documentation recovered from inside the ChatGPT sessions — goals like "establishing persistent and credible accounts" and "maintaining long-term account viability by anticipating platform enforcement," with specific targeting of Facebook's recommendation systems, advertising tools, and reporting mechanisms by name — reads less like a garage operation and more like a contractor deliverable. The OPSEC loop closed inside the target system. That's a novel and uncomfortable operational pattern. It implies the adversary understands the model's capabilities well enough to use it against itself. Ben Nimmo is explicit that the campaigns showed no meaningful third-party engagement — content circulated largely within its own amplification network. By OpenAI's own metric, the operation failed to break out. OpenAI also disclosed, to its credit, that it has a financial interest in data center expansion. Nimmo says it didn't affect the findings. Readers should hold that context anyway. None of which means the structural picture is clean. Three things compound here. First, AI collapses the cost curve on IO quality and scale. Producing 200 localized social posts with region-appropriate imagery used to require a team. It now requires a prompt. The floor on entry has dropped through the basement. Second, the attack surface is domestic sentiment, not fabricated narrative. Gallup polling shows Americans genuinely oppose local data center siting. AI energy consumption anxiety is real and growing. Piggybacking on organic grievance is harder to detect and harder to counter than manufacturing one from scratch — you can't rebut the foreign amplification without inadvertently lending credibility to the underlying debate. Third — and this is the targeting decision that stands out — the tariff cluster deliberately excluded Xi Jinping from content framing tariffs as control mechanisms. Trump-only framing. That's not a content mistake. The operation is designed to look like American populism. Foreign propaganda that is indistinguishable from domestic argument is a different kind of problem than propaganda that is obviously foreign. MITRE mapping for context: AML.T0048 (societal harm via influence operations), T1583.006 (acquire infrastructure: web services), T1585.001 (establish accounts: social media), T1586.001 (coordinated inauthentic behavior), T1588 (obtain capabilities: AI tools for content generation). The immediate threat is low. The campaigns didn't work, and the Breakout Scale scores confirm it. The structural threat is higher than the scores suggest. These are practice runs. The OPSEC is getting documented. The tooling is getting cheaper. The target narratives are already real. Operational failure doesn't mean strategic irrelevance. It means we're watching the rehearsal.

Sources for the above: SafeDep's full technical teardown of the Miasma toolkit — architecture, C2 mechanics, Sigstore forgery module, LOTP injection, dead-man switch — is the primary technical record: safedep.io/inside-the-mia… (June 9, 2026) BleepingComputer on the source code leak itself: bleepingcomputer.com/news/security/… (June 10, 2026) The Register on GitHub's same-day response disabling npm auto-run scripts: theregister.com/devops/2026/06… (June 10, 2026)

The floor opens up under the developer ecosystem when source code for a worm this capable goes public. Miasma — TeamPCP's successor to Shai-Hulud — briefly appeared on GitHub, got yanked, and was obtained by SafeDep and others before it disappeared. The headline is a leak story. The actual story is what got out. Miasma is not a credential stealer with ambitions. It is a fully-engineered supply-chain attack platform: modular TypeScript/Bun architecture, professional ARCHITECTURE.md files, and — per SafeDep's assessment — a codebase that appears to have been maintained with AI coding tooling. The irony of AI tooling being used to build the worm that targets AI tooling is not lost on anyone. The capability inventory is worth sitting with. Miasma injects into 13 AI coding tools — Claude, Copilot, Cursor, Gemini, Kiro, Cline, and seven others. This is "Living off the Pull Request": a compromised developer's AI coding environment becomes a malicious PR machine inside their own repositories, propagating across 12+ languages by injecting into existing project files. It hits npm, PyPI, RubyGems, and JFrog Artifactory. It harvests credentials from AWS, Azure, GCP, Kubernetes, HashiCorp Vault, 1Password, and Bitwarden. It hijacks GitHub Actions workflows via semver orphan commits. Confirmed prior victims include Red Hat npm packages and 73 Microsoft GitHub repositories. Three findings stand out above the rest. First: the Sigstore provenance forgery. Miasma generates valid Sigstore provenance bundles for trojanized packages — packages that look like they were built through a legitimate CI pipeline, signed with legitimate provenance. Sigstore is the foundational verification layer for npm trusted publishing. It is what developers were told, for two years, to adopt as the supply-chain defense. The fact that a leaked worm now automates its forgery doesn't break Sigstore as a protocol, but it meaningfully erodes the assurance model developers were operating under. The trust signal just became noisier. Second: GitHub-as-C2 with three independent channels, each using a different crypto key, all operating over GitHub's commit search API. No custom infrastructure. No domain registrations. No suspicious IPs. No SSL certificate anomalies. Defenders running network-layer detection are, as SafeDep puts it directly, now required to "operate closer to application protocol." The architectural choice to use GitHub's own search as a command channel is elegant in the way that genuinely bad things sometimes are. Third: the dead-man switch. If a stolen GitHub Personal Access Token gets revoked — the expected first move in any incident response playbook — Miasma wipes the victim's home directory. Token revocation, normally a reflexive day-one action, becomes a calculated risk. The worm is designed to make defenders hesitate at the moment they should be moving fastest. The MITRE picture maps cleanly: T1195.001 and T1195.002 for the supply chain compromise paths, T1552.001 for credential harvesting, T1102 for the GitHub C2, T1553.005 for the Sigstore subversion, T1543 for GitHub Actions workflow injection, and T1485 for the home directory wipe. The full kill chain is documented in SafeDep's teardown — one of the more thorough supply-chain malware analyses published this year. GitHub's response landed the same day: npm auto-run scripts disabled as of June 10. That cuts one propagation vector. The OIDC trusted publishing path and SSH paths remain. It's a meaningful move, not a sufficient one. The leak itself is the threat escalation. Pre-leak, Miasma was sophisticated but operator-constrained — TeamPCP held the tooling. Post-leak, any actor with TypeScript literacy can fork the codebase. The Shai-Hulud precedent is instructive: that worm's open-sourcing in 2025 preceded a documented wave of derivative attacks within weeks. SafeDep flagged the parallel explicitly. The 72-hour proliferation window is the historical baseline, and it is already running. What warrants immediate attention: audit GitHub Actions workflows for unexpected semver tag references or orphan commits with cloned author metadata. Rotate GitHub PATs tied to CI/CD, but audit the home directory on any potentially compromised machine before revocation — the dead-man switch risk is real. Review Claude, Copilot, and Cursor config files on developer machines for unexpected hooks. Audit npm/PyPI dependencies introduced in the past 30 days; given the Sigstore forgery capability, verify the build pipeline, not just the bundle signature. And check GitHub commit search patterns in your repos for anomalous base64-encoded strings in commit messages — that is the C2 read mechanism, now fully documented and trivially reproducible. Exploitation is not theoretical. The source code is out. The window is open.
