Autonomous AI Agents Hack Online Retailers for $25 a CompanyGambit Security recovered the staging server of a financially motivated actor running three open-source AI agent harnesses — Strix (vuln scanning), Cairn (autonomous exploitation), and Hermes (orchestration) — against hundreds of online retailers at a marginal cost of tens of dollars per target. The campaign exfiltrated 600,000+ credit card records via Magento database compromises, deployed checkout-page card skimmers on at least 19 confirmed and 100+ further sites, and in one case an agent's own cleanup routine dropped 180 database tables including victim backups. The report details full attack chains (SQLi to RCE to AWS Secrets Manager dump to card decryption), the AI harnesses' operating costs (~$25 mean per target on OpenRouter/opus-4.6/GLM/DeepSeek), and multiple real-world skimmer injection techniques.

Socket: Two Joyfill npm Beta Releases Compromised to Deliver DEV#POPPER Remote Access TrojanSocket's research team found two beta releases of the @joyfill npm packages (@joyfill/layouts and @joyfill/components) contained an import-time JavaScript implant that resolves encrypted payloads through Tron, Aptos, and BNB Smart Chain transactions, ultimately dropping a 77KB Node.js remote-access trojan matching the DEV#POPPER family and sharing loader fingerprints with the PolinRider blockchain-loader campaign. The RAT establishes a Socket.IO C2 channel, executes arbitrary JS/shell commands, exfiltrates files and clipboard data, and persists by patching files inside VS Code, Cursor, Antigravity, Discord Desktop, GitHub Desktop, and the global npm CLI; a parallel detached-process branch fetches an additional bootstrap that can deploy a Python credential/browser-data stealer assessed as an OmniStealer variant.

The author goes further, forging XrML Rights Account Certificates signed with the stolen SLC key to trick a live AD RMS server into issuing genuine use licenses for arbitrary/impersonated identities (a "hybrid" of a Golden Ticket and Silver Ticket), and releases the SharpRMS tool that implements extraction, decryption, and RAC forgery. Because the SLC key has a 255-year certificate and no rotation mechanism, the compromise is permanent for all previously protected content, unlike KRBTGT which can be reset to invalidate forged Kerberos tickets.

The writeup includes fully deobfuscated source code, IOCs (C2 IPs, Tron addresses, file hashes), and results from detonating the packages under Harden-Runner in a sandbox.

CosmosEscape: Taking Over Every Database in Azure Cosmos DBWiz Research found CosmosEscape, a critical Azure Cosmos DB vulnerability exploited via the Gremlin API's .NET-based query engine, whose sandbox failed to restrict .NET reflection, enabling arbitrary code execution on the DB Gateway service. This allowed retrieval of the "Cosmos Master Key," a platform-wide signing key that could fetch any Cosmos DB account's primary key and enumerate accounts via a shared Config Store, enabling attackers to compromise any customer or internal Microsoft database (including those backing Entra ID, Teams, and Copilot) from public endpoints. Microsoft fully remediated the issue and eliminated the master key architecture.

Compromised PyPI Package: mrmustard 0.7.4 Steals SSH, Cloud, and Kubernetes CredentialsStepSecurity reconstructs how a malicious version of XanaduAI's mrmustard quantum-photonics library (0.7.4) reached PyPI: an attacker compromised a maintainer's GitHub account, used a throwaway workflow to exfiltrate the project's PyPI and Codecov tokens via webhook.site, then published a poisoned tarball directly (the malicious code never touched the git source tree). On import, the payload evades CI/container sandboxes, then steals SSH keys, AWS/Kubernetes credentials, and HPC/GPU environment data, XOR-obfuscates it, and beacons to metrics.femboy.energy before installing three persistence mechanisms (cron job, Python .pth hook, shell rc hook).

The workflows execute on GitHub-hosted Ubuntu runners on every push, download an architecture-matched Linux payload from C2 server 43.228.157.68, and run an internet scanner (`ipscan --exploit CVE-2026-41940`) that exploits an authentication bypass in cPanel/WHM and harvests cloud, database, SSH, and source-control credentials, exfiltrating results via heartbeat/results HTTP endpoints and DNSHook callbacks. GitHub code search for the campaign's unique markers returned 6,100-16,000 matching workflow files across unrelated repositories, indicating the abuse extends far beyond the one compromised maintainer and effectively weaponizes GitHub Actions as free, disposable attack infrastructure.

Injective npm Supply Chain Attack: 18 Packages Backdoored to Steal Crypto Wallet KeysOn July 8, 2026, a compromised maintainer account pushed malicious commits directly to the master branch of the InjectiveLabs/injective-ts monorepo, triggering the repo's own OIDC-based GitHub Actions publish pipeline to release backdoored version 1.20.21 of @injectivelabs/sdk-ts and 17 dependent packages. The payload, disguised as 'key derivation telemetry,' hooked PrivateKey.fromMnemonic() and PrivateKey.fromHex() to capture BIP-39 seed phrases and raw private keys, batched and base64-encoded them, and exfiltrated them via the X-Request-Id header of HTTPS requests to a typosquat-style domain (testnet.archival.chain.grpc-web.injective.network) mimicking legitimate Injective gRPC-Web traffic. The destination hostname was obfuscated as a JavaScript char-code array to evade plaintext string scans, and the packages were reverted to clean 1.20.23 roughly 49 minutes after the malicious release.

Because build.rs executes automatically at compile time via Cargo, simply building a project that depends on the crate is enough to trigger the leak, making it a novel build-time supply-chain attack vector distinct from the npm/PyPI postinstall-hook pattern, and notable for exfiltrating source code diffs rather than credentials.

Miasma Worm Hits Microsoft Again: Azure Functions Action and 72 Other Repositories Disabled After Supply Chain Attack Targeting AI Coding AgentsStepSecurity's forensic analysis of the June 5, 2026 Miasma worm incident, in which a compromised contributor account pushed a malicious commit to Microsoft's Azure/durabletask repository planting five files (.claude/settings.json, .gemini/settings.json, .cursor/rules/setup.mdc, .vscode/tasks.json, and a 4.6MB obfuscated .github/setup.js payload) that trigger credential-harvesting code execution the moment the repo is opened in Claude Code, Gemini CLI, Cursor, or VS Code — no package install or code run required. GitHub's automated abuse detection disabled 73 Microsoft repositories in a 105-second sweep, including Azure/functions-action, breaking CI/CD pipelines across GitHub Actions users relying on the mutable @v1 tag. The post ties this to the same compromised account behind the May 19 durabletask PyPI credential-stealer campaign and the broader TeamPCP-linked Miasma worm, which has infected 113+ repositories.

Microsoft's durabletask PyPI Package Compromised in Supply Chain AttackStepSecurity documents the compromise of Microsoft's durabletask PyPI package (versions 1.4.1-1.4.3, 400k+ monthly downloads), where an attacker bypassed the GitHub CI/CD pipeline entirely using stolen publishing credentials to inject a dropper for rope.pyz, a modular cloud-intrusion framework with dedicated collectors for AWS, Azure, GCP, Kubernetes, HashiCorp Vault, password managers, and the filesystem. The framework encrypts stolen data with AES-256-GCM/RSA-4096, exfiltrates via HTTPS, GitHub commit beacons, and attacker-created public repos using the victim's own stolen GitHub tokens, propagates via AWS SSM and kubectl exec, and drops a geo-targeted rm -rf wiper for systems matching Israeli locale/timezone markers. The post ties the attack to TeamPCP's Mini Shai-Hulud campaign (same infrastructure as TanStack, Mistral AI, LiteLLM, @antv) and later updates describe a second compromise of the Azure/durabletask GitHub repo that plants payloads triggering in Claude Code, Gemini CLI, Cursor, and VS Code.

Pythagora-io/gpt-pilot Compromised on GitHub - Shai-Hulud Credential Stealer Blocked by Python LinterStepSecurity documents a June 2026 compromise of the Pythagora-io/gpt-pilot GitHub repo (33.7k stars), where an attacker took over a co-founder's account and force-pushed a Shai-Hulud-variant credential stealer disguised as a "Revert" commit. The malware, a 758KB obfuscated Bun/JavaScript payload delivered via a Python telemetry module, steals AWS/npm/GitHub/Kubernetes/Vault/SSH credentials, uses GitHub commit messages as a covert C2 channel, exfiltrates via newly created GitHub repos, can abuse Sigstore/Fulcio to forge SLSA Build Level 3 attestations, and plants persistence hooks in Claude Code and VS Code. Notably, the attacker's injected code was blocked twice by the project's ruff CI linter/formatter before they gave up, illustrating code-quality tooling as an accidental security control, alongside full IOCs and lessons on branch protection and force-push monitoring.

Active Malware Campaigns in January-May 2026OpenSourceMalware's analysis of active malware campaigns from January-May 2026, focused on Lazarus Group and TeamPCP. Details include Contagious Interview's pivot to abusing .vscode/tasks.json files to deploy BeaverTail/InvisibleFerret, the new TasksJacker campaign (multi-blockchain C2 across TRON/Aptos/BSC, hex-encoded JS hidden in .woff2 font files and a fake spellright.dict) that compromised 400+ repos including DataStax, and the follow-on PolinRider campaign that weaponized stolen credentials via malicious pull requests merged into high-profile projects like VS Code, Apache Superset, Rails, and Expo. Also covers TeamPCP's cascading attack via a leaked Aqua Security service-account PAT used to force-push malicious commits across version tags.

Miasma Blight Reaches Microsoft: 73 Repos Disabled in 105 SecondsInvestigates GitHub's mass disabling of 73 Microsoft repositories across the Azure, Azure-Samples, microsoft, and MicrosoftDocs orgs within a 105-second window on June 5, all flagged for ToS violations, including the widely-used Azure/functions-action GitHub Action that broke CI pipelines globally. The author links the takedown to a re-compromise of the durabletask PyPI package (previously hit May 19 by TeamPCP via stolen GitHub Actions secrets) and to Miasma, a rebrand of TeamPCP's open-sourced Mini Shai-Hulud worm that Aikido and OX Security found had added Azure/GCP credential collectors and self-propagates by committing stolen secrets into attacker-created public repos, which is what likely triggered GitHub's automated abuse enforcement.

Node-gyp Supply Chain Compromise: A Self-Propagating npm Worm That Hides in binding.gypSnyk documents an active npm supply-chain attack ("Node-gyp Supply Chain Compromise - June 2026") that abuses binding.gyp's GYP command-expansion syntax (<!(...)) to trigger arbitrary code execution via node-gyp during npm install, bypassing detection tools that only monitor preinstall/postinstall scripts. The worm, tracked as "Phantom Gyp"/"Miasma" (a Shai-Hulud descendant) by StepSecurity, has hit 57 packages including autotel-* and @vapi-ai/server-sdk, harvests npm/GitHub/AWS/GCP/Azure/Vault/Kubernetes credentials via a multi-stage obfuscated Bun-based loader, injects GitHub Actions workflows for persistence, and self-propagates by republishing from compromised maintainer accounts.
