## Public findings

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

The package's fesm2022 ESM entry (declared as \`module\` in package.json and executed on \`import\` of the library) ends with a trailing \`eval(atob('...'))\` payload that, once decoded, requires \`child\_process\`, \`http\`, \`https\`, and \`zlib\` via \`\\uXXXX\`-escaped identifier strings to hide the imports from static scanners. The loader queries an Ethereum contract at \`0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a\` through \`https://eth.blockscout.com/api\` (with public RPC fallbacks \`1rpc.io/eth\`, \`eth.drpc.org\`, \`ethereum-rpc.publicnode.com\`, \`eth-mainnet.public.blastapi.io\`) to read attacker-controlled host/port values from contract storage, then reaches those hosts over HTTP at paths \`http://${host}:443/0x/cls\` and \`http://${host}:443/0x/ls\` and passes the returned bytes to \`child\_process.spawn\`. This is an EtherHiding remote-code-execution channel: consuming the library in any Node context that evaluates the ESM (SSR, build tooling, dev servers, tests) triggers on-chain-directed download and execution of arbitrary attacker code. The loader is unrelated to the package's advertised checkout functionality, is appended after the legitimate \`export { ZahlenModule,... }\` bundle, and is base64+unicode-obfuscated — hallmarks of an injected supply-chain payload rather than package feature code.
