Summary
Malicious code in fuels-typegen (npm)
Details

-= Per source details. Do not edit below this line.=-

The package name resembles the legitimate @fuel-ts/typegen. On execution of the CLI in bin/cli.js, the code collects the local username (whoami / os.userInfo), os.hostname(), platform, and package name and POSTs them as JSON to the hardcoded endpoint https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9. The manifest's own description states the package's purpose is to POST identifiers to an out-of-band callback, and the bin name (hyperliquid-composer) is unrelated to the package name, consistent with dependency-confusion or typosquat delivery.

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.
