## Source: amazon-inspector (ac3a02c9f004d72f8975e0e93fb0810818b509cf295cf9a567c882afaf9a7444) Package name `warp-contracts-plugin-deploy-test` mimics the legitimate `warp-contracts-plugin-deploy` and copies its public API surface (lib/cjs/index.js re-exports DeployPlugin, CreateContractImpl, SourceImpl, Arweave/Ethereum signers identical to the genuine package). package.json declares `"preinstall": "./bin/install-deps"` where `bin/install-deps` is a 976,568-byte packed Linux ELF binary (sha256 36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36). The package self-describes as a TypeScript Warp Contracts deploy plugin — there is no native source tree, no node-gyp/binding.gyp, no documented purpose for shipping a Linux ELF helper. Readable strings in the binary (LIBBPF, PTRACE, NETLINK_DIAG, HTTP/1.1, https://, USERPROFILE) are inconsistent with any deploy-plugin function and consistent with a host-implant payload. On `npm install`, the binary runs with the installer's privileges, executing attacker-supplied compiled code that the scanner cannot inspect.
