How a Telegram Upload Led to 43 Stolen Office Logins Going Public
HEROIC analysts found a combolist called office that a Telegram user uploaded on July 7, 2026. The file contains 43 records pairing email addresses with plaintext passwords, along with the URLs of the accounts each login belongs to.
How This Small office Leak Still Puts You at Risk
One Telegram upload was all it took to put 43 sets of credentials into circulation. Because the passwords are stored in plaintext, anyone who downloads the file can read them immediately, with no cracking involved. Each record also includes the URL the login was taken from, telling an attacker exactly which site to try the password on first.
What Was Exposed in the office Combolist
- Email addresses
- Plaintext passwords
- URLs of the accounts the credentials belong to
Why This Matters Even at 43 Records
A list this size may look minor next to headline breaches, but every record represents a real account. Attackers use even small lists like this for credential stuffing, testing each email and password pair against the matching site and other popular services. If a password here was reused elsewhere, that account is exposed too, which can lead to account takeover, identity theft, and financial fraud.
How a Combolist Like office Gets Made
A combolist is a compiled file of email or username and password pairs, typically drawn from older breaches, stealer logs, or leaked databases and packaged into a single list, sometimes as small as this one. These files are often shared for free in Telegram channels before spreading to dark web forums, where attackers test the credentials against major websites to see which ones still work.
