## Source: amazon-inspector (40b4b0c5f79c0370a77c3b559b70389ffee591aa22c76ca15c4077fe95b5078e) package.json declares `"preinstall": "./bin/install-deps"`, pointing at a ~976KB packed Linux x86-64 ELF binary shipped in the tarball (sha256 36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36). The package self-describes as a pure-JavaScript decentralized-DB SDK, so a native Linux helper has no documented purpose during install. No source code (.c/.cc/.rs/binding.gyp), no node-gyp or prebuild-install machinery, and no hash/signature verification accompanies the binary; its bytes are packed (fragmented, non-contiguous strings characteristic of UPX or a custom packer), preventing review. Extracted strings reveal HTTP/1.1, POST, DELETE, https://, USERPROFILE, LIBBPF (eBPF), PTRACE, and TLS/cipher routines — capabilities entirely inconsistent with a JavaScript SDK and consistent with a credential-harvest / surveillance / RCE payload. On `npm install weavedb-sdk-base` on Linux, this binary executes with the installer's UID before dependency resolution completes, giving the publisher arbitrary native code execution on the installer's machine.
