The top-level IIFE constructs a hardcoded IPv4 URL by concatenating four numeric literals with '.', issues an HTTPS GET to that bare-IP host, writes the response body to a file under os.tmpdir() with flag 'w+', and immediately spawns it with cwd=os.tmpdir() and windowsHide:true.

The package metadata advertises only 'manage the node' with no functionality justifying any network fetch or binary execution, and the package scope (@antoncarlos1) does not match the linked repository owner (guilderguzman). The fetched bytes are unpinned, unverified, and attacker-controlled; any consumer that requires this package (directly or transitively) executes them with the installer's privileges. ## Source: ghsa-malware (89db8d7da6352641119e0a7d055b53085d0009dae70f854c0aaaad58a78c9f48) 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.
AI Analysis
Technical Summary
@antoncarlos1/[email protected] includes a single obfuscated index.js file that runs a dropper on require(). It constructs a hardcoded IPv4 address, performs an HTTPS GET request to that IP, writes the response to a temporary file, and immediately executes it with the installer's privileges. The obfuscation uses RC4 string arrays and shuffled control flow to hide the malicious network fetch and execution. The package metadata does not justify any network activity or binary execution, and the package scope does not match the repository owner, indicating malicious intent. The fetched payload is unverified and attacker-controlled, leading to full system compromise upon installation or use.
Potential Impact
Systems with @antoncarlos1/[email protected] installed or running are fully compromised because the package executes attacker-controlled code with the installer's privileges. This can lead to complete system takeover, unauthorized access to secrets and keys, and persistent malicious presence. Removing the package alone may not eliminate all malicious artifacts or backdoors introduced by the attacker.
Mitigation Recommendations
No official patch or fix is available for this malicious package. Immediate removal of @antoncarlos1/[email protected] is required. All secrets, keys, and credentials stored on the compromised system should be rotated from a separate, trusted machine. Consider rebuilding or restoring the affected system from a known good backup to ensure complete removal of any attacker-installed components.
