Summary
Malicious code in ams-ssk (npm)
Details

Malicious npm package published by user shetty123 as part of a Telegram account hijacking framework targeting Indian Telegram users. All 31 published versions (1.0.0 through 1.0.33) are malicious. Pairs with common-tg-service, which performs the client-side Telegram account takeover.

ams-ssk is the server-side AMS/CMS infrastructure for the operation. It exposes a file-management CRUD API including a bulk-zip download endpoint (folders/:folder/files/download-all) and a multi-bot Telegram message-forwarder with per-bot operation counters used to fan out hijacked-account traffic. Observed deployments include cms.paidgirl.site and promoteClients2.glitch.me. The package is part of an actor-controlled stack (operator identity shetty123 / display name Mad_man) used to manage stolen Telegram accounts and exfiltrate data to attacker-controlled Telegram channels (-1001801844217, -1001972065816).

Malice executes at runtime when the service is initialized; there are no preinstall/postinstall lifecycle scripts, so the package bypasses install-time scanners.

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.
