Malicious code in get-power (npm)

Type: advisorySource: OSV1 source record

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (e261e4010770fc43fd02cf8c9add484ea5f8a92a21f60682f2aea73f0ce110f7) get-power impersonates ljharb's get-proto utility (package.json declares author 'Jordan Harband ' and homepage github.com/ljharb/get-power) while mirroring get-proto's file layout as cover. On require(), index.js base64-decodes two bundled files disguised as sourcemaps (parse.ts.map, init.ts.map) into parsetmp.js and config.js, require()s parsetmp.js, then fs.unlink()s all four files to erase traces. The decoded payload fetches an AES-256-CBC encrypted blob from https://www.jsonkeeper.com/b/V6NBX via axios, decrypts it with a hardcoded password/salt, and eval()s the plaintext. Whoever controls that paste has arbitrary code execution on any host that installs and loads the package. ## Source: ghsa-malware (a70fd3999ba803e9c66c173bd4e80825b278778f5f3838ab8b29c792a406ae22) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
