--- _-= Per source details.

The spawned file is obfuscated with a custom basE91 string-array decoder; the decoded top-level async IIFE calls globalThis.fetch against a URL on api.jsonbin.io/v3/, parses the JSON response, and passes the `record.cookie` field to new Function('require', body)(require), executing attacker-controlled JavaScript with full `require` access on the installer at install time. api.jsonbin.io is a public, mutable, anonymous JSON-hosting service, so the executed payload can change at any time. Adjacent to the loader, lib/utils/smtp-connection/LICENSE is a 262KB file whose contents are a hex-encoded ~131KB opaque binary blob rather than license text, colocated with the loader as a staged secondary payload. The advertised package purpose has no relationship to the shipped SMTP source, providing cover for the injected dropper. ## Source: ghsa-malware (3b0064885ea23f15a06a6ad10a6d57a101499e6015da4d94d8c49cc481ae34f0) 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.
