Researchers Find 1,367 Leaked Logins in the ‘Ok’ Telegram Combolist

In August 2025, HEROIC analysts tracked a small combolist titled simply "Ok," uploaded by a Telegram user. Despite the plain name, the file contains 1,367 real records combining email addresses, plaintext passwords, and the URLs those credentials were used on. Why This Is Dangerous: a forgettable file name doesn't mean forgettable risk. Every line in this list is a working email and password pair, stored in plain text, that an attacker can copy and use to attempt a login without any extra effort. What Was Exposed: email addresses, plaintext passwords, and URLs tied to each account. Why This Matters Even for a Small List: smaller combolists like this one are often overlooked, but they circulate just as widely as larger ones on Telegram and dark web forums. Anyone whose credentials appear here faces the same risk as someone in a million record breach, credential stuffing, account takeover, and the potential for identity theft if the password is reused elsewhere. How These Small Combolists Get Made and Shared: small, casually named combolists are frequently posted for free in Telegram groups as samples or goodwill gestures to build a following before a bigger, paid list is advertised. They're typically pieced together from older breach data or phishing results rather than fresh malware output, but the credentials can still work if the victim hasn't updated their password since. Check If You Are Affected: don't let a small file name fool you into thinking the risk is small too. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including combolists like this one, so you can find out in seconds if you were exposed.
