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.
