Malicious code in weavedb-lite (npm)

Details

--- _-= Per source details. Do not edit below this line.=-_

## Source: amazon-inspector (3017d9faf2f1f8a8973162392159e8d185b9c676555d406da261e67cd95395e8) package.json declares `"preinstall": "./src/deps.ts"`, but `src/deps.ts` is not TypeScript — its first bytes are the ELF magic (`\x7fELF\x02\x01\x01`), identifying it as a ~954 KB Linux x86-64 executable (sha256 36abd242…b436d36). Renaming a native binary with a `.ts` extension is deliberate disguise to evade reviewers and scanners. Running `npm install weavedb-lite` on Linux directly executes this opaque binary on the installer's machine before any other code runs, with no source, no documented purpose, no version pin, and no integrity verification. Extracted strings include HTTP/POST and `https://` indicators consistent with network exfiltration or C2 callback, but the binary's actual behavior cannot be inspected statically. Additionally, the package name `weavedb-lite` mimics the WeaveDB ecosystem and declares `bin` entries (`wao`, `wao-esm`) that collide with the legitimate `wao` package it also depends on, fitting a typosquat/namespace-abuse pattern targeting developers searching for WeaveDB or wao tooling. The preinstall ELF execution alone is sufficient to block; the typosquat shape corroborates intentional impersonation.
