## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

@torbeck/heap impersonates the legitimate @datastructures-js/heap package: README.md line 1 reads \`\# @datastructures-js/heap\`, package.json sets homepage/repository/bugs to github.com/datastructures-js/heap and author to \`Eyas Ranjous \<eyas-ranjous@gmail.com\>\`, while the npm scope \`@torbeck\` is unrelated. The package re-exports the genuine Heap class so consumers get a working API. Appended to src/heap.js after \`exports.Heap = Heap;\` (around line 247) is a heavily obfuscated obfuscator.io payload (two rotated string-array RC4-style decoders, ~580 and ~700 entries, with Function.toString anti-tamper traps and console-method override checks). On \`require('@torbeck/heap')\` via the package's index.js main entry, the payload derives an AES key by XORing four hardcoded buffers, decrypts a hidden URL, issues an http/https.request to download a binary into os.tmpdir(), writes a PID lock and.meta.json with a sha256, chmods the file to 0755, and spawns it detached via process.execPath or \`bash -c\` with stdio:'ignore', windowsHide:true, and unref() — plus a re-exec wrapper that respawns the parent under a sentinel. Platform-specific branches handle win/linux/mac. There is no version pinning or signature check on the downloaded bytes, the URL is concealed by obfuscation, and the dropped binary's purpose is unrelated to a heap data-structure library. This is a typosquat carrying an install/require-time RCE dropper.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
