On connect, the injected code issues an authenticated `w:mex` FOLLOW\nquery (query_id 7871414976211147) against one or more attacker-chosen WhatsApp Channel/Newsletter\nJIDs, using the installer's own authenticated WhatsApp session -- silently subscribing the\nvictim's account to channels it never asked to join.\n\nThe target JID(s) are hidden from casual source review via one of several obfuscation techniques\nobserved across the family: a plain string literal, base64 encoding, base64+XOR, or a char-code\narray reconstructed at runtime. Some variants instead fetch a mutable, attacker-controlled remote\nJSON/JS list of target JIDs from GitHub or another host at runtime, letting the target list change\nafter installation without a new npm publish. Every sample in the family shares the same underlying\nmechanism (a wrapped/patched socket-connect routine that fires the FOLLOW query some seconds after\nconnect), even though the package name, JID value(s), and obfuscation/delivery method differ per\nfork.\n\nThe malicious action abuses the installer's own authenticated WhatsApp session to gain reach and\nsubscribers for attacker-controlled channels; it does not exfiltrate credentials, establish\npersistence, or execute arbitrary remote code.\n\nAffected package: kiyoramarkets (npm), version(s): 8.0.16.\n\n---\n_-= Per source details.

On every socket connection, socketConnect() fetches a JSON list from a hardcoded GitHub raw URL constructed by decoding a char-code array (resolves to https://raw.github.com/skyzopedia/NewsletterID/refs/heads/main/VIP_Push.json) and issues mex queries with query_id 7871414976211147 (newsletter action) against each returned id under the installer's account. prepareWAMessageMedia silently defaults the annotations field on outgoing media messages to a hardcoded newsletter reference (newsletterJid 120363409159786018@newsletter, name 'skyzopedia'), attributing/promoting the author's newsletter through media the installer's bot sends. An additional helper generateMessageV decodes a base64+XOR-obfuscated '@newsletter' literal and, on a 40s timer, invokes a callback with the same query_id. The behavior uses the installer's session identity for the author's reach; no credential theft, no filesystem access outside the library, no RCE, no exfiltration of installer secrets is present.\n\n## Source: ghsa-malware (50aac4306f42109e26f9c69aeb99a2f2a33d5639b3ac23638734b2a4aeef9789)\nAny computer that has this package installed or running should be considered fully compromised.
