Galaxy Research's weekly brief includes a detailed postmortem of the $387.5M Bitget hack: attackers exploited a zero-day in two unnamed third-party security products ("Product A"/"Product B") to obtain high-level internal credentials, inserted forged withdrawal commands into Bitget's wallet backend across 11 chains, then deleted the fraudulent commands — with Bitget attributing the attack to North Korean actors based on IP behavior and wallet overlaps found by Elliptic and TRM. The piece draws a direct parallel to the $1.5B Bybit/Lazarus heist (compromised Safe{Wallet} infrastructure rather than stolen keys) to argue that private-key cryptography is effectively solved and attackers now target the approval pipeline/intermediary services instead; it also covers the follow-on $3.8M NEAR Intents Omni-bridge exploit and THORChain's continued role laundering DPRK proceeds.

NEAR Intents, a cross-chain swap protocol, suffered a $3.8M exploit caused by a bug in how its Omni deposit/withdrawal layer interacted with its main smart contract. General manager Alex Shevchenko publicly identified the attacker, gave a 48-hour ultimatum to return the funds as a last-chance responsible-disclosure offer, and the full amount was returned after an on-chain apology message. The stolen funds had briefly moved through KuCoin and were bridged to Bitcoin, traced by ZachXBT; separately, days earlier NEAR Intents had blocked a $50M swap attempt tied to the DPRK-linked Bitget hacker.

Galaxy Research post-mortem on the $387.5m Bitget hot/warm wallet theft across 11 chains, attributed to North Korean (Lazarus/DPRK) actors via IP behavior and onchain wallet-overlap analysis by Elliptic and TRM. SlowMist traced the intrusion to a zero-day exploit against two unnamed third-party security vendors ("Product A"/"Product B") that let attackers insert and then delete fraudulent withdrawal commands in Bitget's wallet backend, rather than compromising private keys or cold storage. The piece draws a direct parallel to the February 2025 Bybit/Safe{Wallet} $1.5B theft (doctored signing interface) and the same-week NEAR Intents $3.8m hot-wallet exploit, arguing that private-key cryptography is now reliably secure so attackers instead target the intermediary infrastructure/pipeline that authorizes transactions, with stolen funds repeatedly laundered through THORChain.

Orca Security details a supply-chain attack on the npm package @dforge-core/dforge-mcp, where a compromised maintainer account modified the GitHub Actions release workflow so any push to main triggered an OIDC-based trusted publish, shipping malicious version 0.2.21 with valid Sigstore provenance. The four-stage GHAPPIER loader activated only when the MCP server launched, deployed a self-deleting remote shell, and per CloudSEK's tracing appeared across 65 repos and 22 accounts; a second payload matched PolinRider, a DPRK-linked campaign using Ethereum transactions for C2. The piece underscores that npm provenance attests build origin, not source integrity, and lists remediation steps since no CVE or advisory yet exists.

Socket's Threat Research Team reports that the PolinRider campaign (linked to North Korea/DPRK operators) has spread malicious code into four dev-* branches of visanduma/nova-two-factor, a Packagist package with over 700,000 cumulative downloads, via a compromised GitHub account (LaHiRu) in the Visanduma organization. The post details the campaign's tradecraft — hiding payloads in .woff2 font files, using VS Code's "runOn": "folderOpen" task trigger, and a new technique inserting obfuscated JavaScript directly into index.php executed via PHP's shell_exec — and explains how Packagist/Go modules resolving code straight from Git repos lets planted source code reach downstream users without stolen registry credentials. It provides IOCs (package versions, wallet address, IPs, file hashes) and frames PolinRider as a slow, persistent Git-collaboration-based intrusion campaign primarily aimed at cryptocurrency theft.

Chainalysis research on blockchain dead drops (BDD), the practice of storing malware C2 payloads and configuration pointers on public blockchains (EtherHiding and its variants) so infrastructure survives takedowns. It details three attributed case studies: DPRK linked UNC5342 using a TRON and Aptos to BSC cross-chain relay to deliver crypto-stealing malware via fake job interviews, Iran-nexus actors embedding C2 in Bitcoin OP_RETURN transactions tied to a Satoshi-era address, and a Russian-language Malware-as-a-Service operation running resolver contracts on Polygon across dozens of downstream customers. It reports a 420 to 440 percent YoY surge in BDD activity, attributes it partly to unrestricted open-weight Chinese LLMs lowering the barrier to entry, and maps the technique to MITRE ATT&CK T1102.002.

OpenSourceMalware researchers detail WeaselBiscuit, a newly discovered lightweight JavaScript infostealer found hidden in 11+ npm packages (e.g. process-tailwind, engin1, the @biz44 scope), which shares tradecraft with DPRK-linked BeaverTail/OtterCookie but strips out wallet-draining, password decryption, and remote-shell features. The writeup walks through the full infection chain - a package auto-running a detached Node loader, fetching a Base64-encoded second stage from Npoint dead-drop URLs, and beaconing to a hardcoded HTTP C2 (103.170.217.184:8787) - plus its capabilities (Chrome extension-storage theft, clipboard capture, Windows keylogging) and a campaign-cluster graph tying packages together via shared hashes and resolver URLs. Attribution to DPRK is explicitly labeled a tentative hypothesis rather than confirmed.

The hosts detail the expanding reachability-based targeting of JS/TS/CJS/MJS files, the new NullReceiver-branded payload, and a real case study (Gutenberg maintainer "Diogo"/fetch-page-assets) where DPRK pushed malicious updates riding along on the developer's own legitimate npm publishes, underscoring why disclosing infections to collaborators is necessary to stop reinfection through shared repos.

OpenSourceMalware's case study on npm packages fetch-page-assets and html-to-gutenberg, maintained by a legitimate developer (DiogoAngelim) whose GitHub account was compromised by the DPRK-linked PolinRider campaign in March 2026. The post shows GitHub server-side push timestamps proving all seven of the maintainer's repos were force-pushed with an identical NullReceiver loader in two coordinated bursts, and that after npm pulled the flagged v1.2.9 (GHSA-vxq2-vhm7-7mhq), every subsequent release (v1.2.10-v1.2.14) kept shipping the same .vscode/tasks.json auto-run trigger, with the attacker later adding a second obfuscated payload appended to babel.config.cjs.

Episode 18 of the OpenSourceMalware Show discusses the compromise of Rust maintainer 'dhrundy' that pushed malicious versions of arrayref (245M+ downloads), internment, and append-only-vec with a typosquatted build dependency executing a remote binary at compile time, which Wiz Research ties to DPRK infrastructure shared with the Mastra and Axios npm compromises. It also covers StubMaker, a campaign that started as RubyGems typosquats of bundler/i18n/rake/activesupport and shares byte-identical payloads (a 22MB Rust loader with an embedded Go infostealer, including a Chrome App-Bound Encryption bypass) with a 40-package npm typosquatting cluster targeting axios, chalk, commander, lodash, react and typescript, with signs it also hit PowerShell. The hosts also note a rising trend of attackers bundling compiled C++/Rust/Go binaries in npm/RubyGems packages (a red flag for analysts) and a PolinRider reinfection wave now using NullReceiver instead of EtherHiding for stage-two C2 hiding.

Wiz researchers found that malicious versions of the Rust crates arrayref, internment, and append-only-vec were published to crates.io, each pulling in a typosquatted build-dependency (proc-macro1, mimicking proc-macro2) whose build.rs executes a remote payload at compile time. The payload beacons to a C2 endpoint (/49890878) shared with the Mastra campaign, disables TLS validation, enumerates Chrome/Brave/Edge saved logins via their SQLite stores, persists via Registry Run keys/LaunchAgents/systemd, and falls back to a DGA — with C2 infrastructure and SSL-issuer overlap tying it to DPRK/Sapphire Sleet activity previously seen in the Mastra and axios supply chain attacks. arrayref is used in roughly 75% of Rust environments, making this a high-impact build-time compromise.

Aikido researchers detail a supply-chain compromise of three popular Rust crates maintained by the same author, arrayref with 244M downloads, append-only-vec with 4M, and internment with 14M, that were modified to add a single malicious manifest dependency, proc-macro1, a typosquat of proc-macro2. Because the dependency's build.rs executes automatically during cargo build, merely compiling a project pulling in any of these crates downloads and runs a platform-specific payload that drops an infostealer targeting Chromium browser credentials and crypto-wallet extension storage, installs macOS LaunchAgent persistence, and beacons to a lightweight C2 supporting remote shell commands. The campaign's TTPs closely mirror the prior npm-based Axios and Mastra compromises attributed to DPRK, suggesting the same actor expanding into the Rust ecosystem.

Researchers analyzing the DPRK-linked npm packages bianira-ui@1.27.0 and fluid-type-ui@2.0.8 (Contagious Interview campaign, trojanized clones of Tailwind CSS plugins) identified NullReceiver, a new blockchain C2-resolution technique that encodes the C2 IP address directly in the bytes of the recipient address of a zero-value, zero-data Ethereum transfer, rather than in calldata as with EtherHiding. Because it uses a disposable, never-reused destination address and carries no data field, it avoids the fixed "burn address" landmark that let Google's GTIG detect EtherHiding, making it harder to fingerprint.

OpenSourceMalware's research ties together JFrog's, Nextron's, and Socket's separate reports on compromised html-to-gutenberg/fetch-page-assets npm packages, 16 Go modules, and Joyfill's poisoned beta releases, attributing all of them to DPRK's PolinRider campaign via shared XOR keys, TRON/Aptos wallets, C2 infrastructure, and the fa-solid-400.woff2 loader file hash. The piece argues these aren't targeted account takeovers but automated propagation from infected maintainer machines (via temp_auto_push.bat git history rewriting and stolen .npmrc tokens), and uses GH Archive to prove that 43 of 64 analyzed Go module pseudo-version timestamps were forged to appear years older than the actual malicious push.

An OSINT investigator analyzes a WorldLeaks ransomware group data leak of Reliance Infrastructure (hosted by third-party vendor Yotta), which exposed 14.3GB / ~19,000 files related to India's Kudankulam Nuclear Power Plant (KNPP) — including RFC drawings, PPS fencing designs, HVAC/fire specs, and vendor/employee records. The piece profiles WorldLeaks (a Hive/Hunters International spin-off), lists MD5/SHA-256 hashes for its RustyRocket exfiltration tool, and discusses supply-chain vendor risk, industrial espionage by nation-state actors (Lazarus/DPRK, China), and insider credential trading as threats to critical nuclear infrastructure.

Weekly OpenSourceMalware podcast episode covering four security stories: GitHub enabling a default 3-day Dependabot cooldown to blunt account-takeover malware; the JScrambler npm compromise where a stolen/unknown publishing credential was used to push five malicious versions (moving the trigger from a pre-install script to on-import execution) plus four pinned dependent packages; the AsyncAPI compromise via a 58-day-unpatched GitHub Actions pull_request_target flaw that let attackers steal a privileged token and publish malicious @asyncapi npm packages containing components derived from the open-sourced Miasma malware; and new PolinRider (DPRK-linked) research showing a 6.5x rise in confirmed poisoned repos since March, with 94% of payloads delivered via JavaScript config-file injection and the rest via fake font files, plus multiple redundant triggers via VS Code task.json and git post-checkout/pre-commit hooks targeting individual developers previously compromised via Contagious Interview/TasksJacker.

OpenSourceMalware's July hunt update on the PolinRider campaign (a Lazarus Group/DPRK operation linked to Contagious Interview and TasksJacker) found 2,417 newly-compromised GitHub repos, bringing the confirmed footprint to 4,367 repos across 2,152 owners — a 6.5x increase since March. The post breaks down the two injection vectors (94% config-file injection into files like postcss.config.mjs/tailwind.config.js/eslint.config.mjs, 6% payloads hidden in a .woff2 font file), shows the campaign overwhelmingly hits individual developer accounts rather than orgs, and republishes updated signature markers, decoder function names, and grep-based detection/remediation steps.

Episode 12 of the OpenSourceMalware Show covers three security stories and features an extended interview with Mikael Barbero, Head of Security at the Eclipse Foundation, about securing Open VSX. The interview details Open VSX's pre-publish YARA/AI-assisted malware scanning pipeline, quarantine-and-human-review workflow, token expiration and revocation overhaul, namespace/publisher verification, and detection of 'sleeper' extensions that turn malicious after an update (as seen with GlassWorm-style campaigns). The quick-hits segment covers Paul McCarty's PolinRider research showing a DPRK automated repo-hijacking campaign spreading into Go and PHP ecosystems via Packagist/Go registry packaging of GitHub repos, a cybersecurity startup caught publishing seven infostealer npm packages to manufacture its own threat data, and MeetingTV's lawsuit against Palo Alto Networks/Koi Security alleging an AI-hallucinated domain on a C2 IOC list caused real business harm.

OpenSourceMalware documents how PolinRider, a DPRK/Lazarus Group supply-chain campaign tied to the Contagious Interview cluster, spread from GitHub account takeovers into Go modules, Packagist/Composer packages, npm libraries and Chrome extensions without any change to the malware itself. Because Go and Packagist resolve packages directly from git tags rather than a separately-uploaded artifact, a compromised GitHub account automatically becomes a compromised registry release — unlike npm/PyPI, which require a separate publishing credential and largely stalled the takeover at the registry boundary. The post gives ecosystem-by-ecosystem evidence (10 Packagist packages, 80+ Go modules, an NPM/Chrome cluster), IOCs (TRON/Aptos dead-drop addresses, XOR keys, loader signatures, temp_auto_push.bat), a campaign timeline, and remediation guidance for Go/Composer maintainers.

Wiz Research found that the Amazon Q Developer VS Code extension auto-loaded and executed MCP server configs from .amazonq/mcp.json in a workspace with no consent prompt or workspace-trust check, and spawned those processes with full environment inheritance. Opening a malicious repository (e.g. a malicious PR, typosquatted package, or fake "coding test" per known DPRK social-engineering tactics) could therefore trigger arbitrary code execution and theft of the developer's AWS credentials, demonstrated by capturing aws sts get-caller-identity output. Amazon remediated the issue in language server version 1.65.0, adding a consent prompt before loading workspace MCP servers.

Podcast/video episode of The OpenSourceMalware Show where researcher Paul McCarty details three active DPRK Lazarus Group supply-chain malware techniques: "version sandwiching" (publishing benign package versions before and after a malicious one, then pinning delivery to the malicious version so latest-version scanners miss it), reuse of Aptos/Tron/Binance BSC blockchain addresses with mutable memo fields as C2 infrastructure to tie campaigns together, and human-readable campaign name strings (e.g. a6-shadow-15, a6-orion-271) embedded in payloads for internal tracking. It also covers broader trends: low-sophistication threat actors using vibe-coding to port payloads across npm/PyPI simultaneously, "package clusters" where only 1-2 of several published packages carry the actual payload, and dynamic imports/payload splitting that pull code from arbitrary CDN URLs at runtime to bypass package managers, firewalls, and Artifactory.

SentinelLABS dissects macOS.Gaslight, a Rust macOS implant (tracked via Apple XProtect's MACOS_BONZAI_COBUCH rule, linked to DPRK-aligned BONZAI/AIRPIPE activity) that uses a Telegram Bot API polling channel with AES-GCM-over-pinned-TLS, self-redacts its bot token from runtime logs, stages a runtime-fetched standalone CPython interpreter to run a Python keychain/browser/history stealer, and persists via a fake com.apple.* LaunchAgent. Its standout feature is a 3.5 KB embedded block of 38 fabricated "system" messages mimicking an LLM triage harness's prompt scaffold, engineered to make an AI-assisted analyst tool abort or refuse analysis rather than evade the sandbox itself.

An analysis of npm v12 (shipping ~July 2026, previewable on npm 11.16.0+), which flips three dangerous defaults to deny-by-default: automatic preinstall/install/postinstall lifecycle scripts, git dependencies (now requiring --allow-git), and remote HTTPS tarball dependencies (now requiring --allow-remote). The author, a DEF CON speaker on install-script abuse, argues the changes are genuinely good but warns that widespread legitimate use of install scripts (esbuild, sharp, core-js, puppeteer, node-gyp native builds) will drive developers toward reflexive npm approve-scripts approval, and that attackers will simply relocate payload execution outside npm's visibility (curl|bash in install.js, bootstrap binaries), citing DPRK actors' continued abuse of VSCode tasks files even after Microsoft disabled task.allowAutomaticTasks by default. It also surveys complementary controls gaining traction across the ecosystem: npm's min-release-age cooldown (following pnpm's minimumReleaseAge, Yarn's npmMinimalAgeGate, and Bun) and package-firewall products (Datadog's supply-chain-firewall, Liran Tal's npq, Socket, Aikido, Endor Labs).

Socket researchers found malicious obfuscated JavaScript appended to a tailwind.js file inside a dev branch (dev-drewroberts/feature/test-case) of the legitimate Laravel package roberts/leads on Packagist. The payload uses TRON, Aptos, and BNB Smart Chain RPC services as a blockchain "dead drop" to fetch XOR-encrypted second-stage code, decrypt it, and execute it via eval() and a hidden detached Node.js child process, consistent with prior DEV#POPPER/OmniStealer/BeaverTail-family DPRK campaigns. The activity is attributed to Famous Chollima and resembles a Contagious Interview-style fake job/recruiter lure targeting PHP/Laravel developers, with full IOCs (wallets, XOR keys, hashes) and detection guidance provided.

Huntress recaps its April Tradecraft Tuesday panel (with researchers from Wiz and Aikido Security) on the March 2026 axios npm supply chain compromise, in which attackers took over maintainer jasonsaayman's account via an elaborate fake-company/fake-Slack/Teams social-engineering scheme and published two backdoored axios releases ([email protected], [email protected]) carrying a cross-platform RAT. Huntress observed at least 135 endpoints contacting the attacker's C2 during the three-hour exposure window before npm pulled the versions, and Google attributed the campaign to UNC1069, a financially motivated DPRK-linked actor. The piece also contrasts the incident with other 2025-2026 npm attacks (qix account phishing, the Shai-Hulud worm, the Trivy/TeamPCP token-theft spread) and recommends dependency pinning, age-based version gating, and the Clean Source Principle as mitigations.

Huntress's rapid-response analysis of the March 2026 compromise of the axios npm package, in which an attacker took over maintainer jasonsaayman's npm account and published backdoored axios releases (5.14.1, 4.2.1) depending on a phantom package plain-crypto-js whose postinstall script dropped a cross-platform RAT to macOS, Windows, and Linux. The writeup details the obfuscated dropper (setup.js), platform-specific payloads (wt.exe EDR-evasion trick on Windows, com.apple.act.mond on macOS, /tmp/ld.py on Linux), the shared C2 protocol at sfrclak[.]com, and evidence tying the campaign to DPRK-linked actors (UNC1069/BlueNoroff), plus remediation and hardening guidance.
