The binary is run as the installing user on every `npm install`. Strings inside the ELF include `LIBBPF`, `PTRACE`, `HTTP/1.1`, `POST`, `USERPROFILE`, and `Ed25519` \u2014 capabilities (eBPF, process tracing, HTTP POST, cross-platform home-directory paths, key handling) that are unrelated to an Arweave deploy CLI. The package is also a clear impersonation of the legitimate Arweave `arkb` tool: it declares `\"bin\": { \"arkb\": \"./bin/app.js\" }` so `npx arkb` resolves to this package, its commands.js duplicates the real arkb help output (`arkb ${command + usage}`), and it lists `@textury/ardb` as a dependency to ride on the textury/Arweave brand. The combination of a typosquat lure plus an opaque preinstall native binary with no matching source is the canonical install-time-RCE / dropper pattern: any developer who runs `npm install arnext-arkb` (or installs it transitively) executes attacker-controlled native code under their own account before any other code runs.\n\n## Source: google-open-source-security (146faaf0d97c6a533a969bc3f3f117811f9317dc865ed4ab37f1679842ddeaae)\nThis package was compromised as part of the IronWorm campaign. This campaign executes a malicious binary payload during installation via a preinstall hook. The payload is a Rust-built infostealer that targets developer environments, scanning for and harvesting credentials related to cloud providers, object storage, databases, source-control, package registries, and AI developer tools. It also targets cryptocurrency wallets, specifically injecting a malicious JavaScript hook into the Exodus desktop wallet to capture passwords and recovery phrases. Furthermore, the malware exhibits worm-like behavior by stealing GitHub and NPM credentials to push malicious updates to the victim\u0027s repositories and publish trojanized packages, and it uses an eBPF-based kernel rootkit to hide its processes and network connections on Linux systems.\n",
