"Protected document" invoice sign-in kit that sends credentials to Telegram

family: adobe-protected-invoice-telegram-kit-2026-10

Credential phishing kit that poses as a protected document: an Adobe sign-in box over a blurred invoice from a made-up company, with the invoice number, dates and amount due shown beside the form. The victim's email address is filled in from the link they were sent. Everything typed is sent to the operator through Telegram, and the page then shows an "invalid credentials" error with a reference number whatever was entered, so victims try again with other passwords. The page is translated into 20 languages and picks one from the browser or the visitor's location. The kit sits in a folder on compromised websites and is reached through newly registered redirect domains such as invoice-adobe[.]com. A match means a page carrying the kit, or a scan of a known redirect domain.

One hunt for the campaign. Rule anchor: the kit's own code (the Telegram submission, a hard-coded credential check that always fails, the error page and the email prefill), not the brand or the invoice text, so a copy showing another brand or another invoice still matches. Search anchor: the reported redirect domain and the invoice title of the first copy. The redirect domain serves a one-line JavaScript redirect and nothing else. The compromised sites hosting the kit are not listed here.
