Summary

Malicious code in bolt-delivery-menu-app (npm)

Details

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

Package executes a DNS-based beacon at both install time (package.json scripts.install runs node index.js) and on every require() of the module. lib/core.js reads os.userInfo().username, os.hostname(), and process.cwd(), concatenates them with a campaign tag into a single label, and triggers dns.resolve4 against that label under the attacker-controlled domain oob.sl4x0.xyz, leaking installer host identity over DNS (a channel chosen to bypass HTTP-egress controls). The C2 domain and Node built-in names (os, dns, process, resolve4) are stored as char-code arrays in lib/b02e30.js and lib/6ad264.js to defeat string-grep scanners. The package name bolt-delivery-menu-app impersonates the Bolt delivery brand while shipping generic 'Enterprise Utilities' boilerplate as its cover story, and the author email research@sl4x0.xyz resolves to the same domain as the exfil destination — the typosquat lure, the cover identity, and the C2 are one operation. README falsely claims 'No network requests'.

Source: ghsa-malware (f2e714b1c92f35d144d33ee67260f7a6d90e5055a37a54914a50949871a0d002)

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.
