PrimeNgScraperBase.core sends login passwords to the author's Telegram chat

Conclusion: malicious
Covers: 1.0.40 and 1.0.19
Reviewed by: Bitbison
Updated: 2026-11-07

A NuGet package whose login controller forwards submitted usernames and passwords, and other user activity, to a hard-coded Telegram chat.

PrimeNgScraperBase.core is a NuGet package whose description is "base scraper backend with user management". It is a single precompiled .NET assembly, lib/net9.0/PrimeNgScraperBase.core.dll, that provides ASP.NET controllers for password and Google login, tickets, tasks, subscriptions and usage. When an application uses those controllers, the library makes HTTPS POSTs to the Telegram Bot API with a hard-coded bot token and chat id, and puts user data in the message text. It is not a hidden install hook; the exfiltration is in the ordinary login and ticket endpoints.

What PrimeNgScraperBase.core does

An application that uses the package's controllers and receives a login attempt triggers a request to api.telegram.org. On a failed password login, the submitted username and password are included in the message. Successful logins, Google logins, new Google users, ticket creation, ticket messages and ticket status changes are also sent to the same chat.

What the code does

PrimeNgScraperBase.core.Services.TelegramService (decompiled from lib/net9.0/PrimeNgScraperBase.core.dll) holds a hard-coded Telegram bot token and a Send method that posts a form to https://api.telegram.org/bot<token>/sendMessage with a hard-coded chat id and the message text (lines 1918-1943 of the decompiled assembly).
UserController.Login sends "Login attempt failed for {credential.Username}, {credential.Password}" to that chat when a login fails, so the submitted password leaves for the author's Telegram chat (line 5270).
UserController.Login sends "{credential.Username} logged in" on success (line 5279); UserController.GoogleLogin sends "{username} logged in with Google" and "new Google user {username} created" (lines 5356, 5390).
TicketsController.Create, AddMessage and UpdateStatus send ticket titles, message text, usernames and status changes to the same chat (lines 4636, 4673, 4703).
The destination token and chat id are hard-coded; no setting disables these sends.

Timeline (UTC)

When	What
2025-08-13	1.0.1 published, without the Telegram code
2025-09-30	1.0.19 published, introducing the Telegram sends and the failed-login password forwarding
2026-05-23	1.0.40 published, still containing the same code
2026-11-07	still served on NuGet; the credential forwarding remains in the shipped assembly

If you installed it

Remove the package, and treat any credentials submitted to an application that used it from version 1.0.19 onward as compromised: usernames and passwords from failed login attempts are forwarded to a Telegram chat outside your control. The destination is hard-coded and cannot be turned off by configuration.
