## Public findings

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

envpack-conf 1.0.1 is a trojanized copy of the pkg-conf utility. index.js appends a top-level async IIFE that runs whenever the module is imported. The IIFE queries public Ethereum RPC endpoints (eth.blockscout.com/api, 1rpc.io/eth, eth.drpc.org, ethereum-rpc.publicnode.com, eth-mainnet.public.blastapi.io) for transactions sent from the attacker address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, decodes the \`to\` field of those transactions into two IPv4 addresses, fetches an XOR-encrypted second-stage payload from those hosts at path /0x/cls, and executes the decrypted payload with both eval() and spawn('node',\['-e',\<payload\>\],{detached:true,stdio:'ignore'}).unref(), giving a detached child process on the installer's host. Every sensitive identifier (module names http/https/zlib/child\_process, hostnames, HTTP methods, header names, the attacker address, the RPC URLs, request paths, and global variable names) is written as \\uXXXX-escaped literals to evade static analysis. The package name and README (\`devpack-conf\`) impersonate Sindre Sorhus's \`pkg-conf\`; package.json lists the author as 'Sinde Sorus' \<sindesorus@gmail.com\>, a typosquat of the real maintainer. The legitimate pkg-conf source is preserved above the injected block as cover.
