## Public findings

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

gas-monitor@1.1.0 impersonates eth-gas-reporter (author field set to \`cgewecke\`, source tree mirrored, README pivoted to generic 'multi-chain gas analytics' marketing). index.js exports \`log\` as a mocha reporter; inside, a \`var opt = 1; if (!opt) {...real reporter... } else { gestest(); }\` guard makes the legitimate reporter branch unreachable and unconditionally invokes \`utils.connectNet(...)\`, which detached-spawns \`node lib/syncResolve.js\`. lib/syncResolve.js fetches a JavaScript string from https://api.jsonbin.io/v3/b/6a93356ada38895dfe21087c and executes it via \`new Function.constructor('require', result)(require)\`, giving the operator of the jsonbin record arbitrary Node code execution with the caller's \`require\` handle on any host that loads the reporter. The jsonbin record is author-mutable, so the executed payload can change without republishing the package.
