OJS_Valid Leak: 44 Accounts Exposed in a Telegram Combolist Drop

HEROIC analysts identified a small combolist named OJS_Valid that a Telegram user uploaded on March 19, 2026. The file contains 44 records pairing email addresses with plaintext passwords and the URLs the credentials were meant to unlock. It is a small file by breach standards, but every credential in it is real and reusable by anyone who finds it. Why This Is Dangerous: Because the passwords are stored in plaintext, an attacker does not need to crack or decrypt anything. They can copy the email, password, and URL directly from the file and attempt to log in immediately. If any of the 44 people reused that password on other accounts, the risk extends well beyond the original login. What Was Exposed: Email addresses, plaintext passwords, and the URLs tied to each account. Together these three fields give an attacker a ready-made login attempt for every record in the file. Why This Matters: Small combolists like this one are routinely combined with dozens of others into larger credential-stuffing lists. A criminal doesn't need OJS_Valid to be famous or large to profit from it. They only need a handful of the 44 accounts to still be active and reused elsewhere to pull off account takeover, financial fraud, or identity theft. How This Combolist Was Built: Combolists like OJS_Valid are typically assembled from older breaches, phishing kits, or malware logs, then repackaged and shared for free or sold cheaply on Telegram and hacking forums. They rarely come from a single hack of one company. Instead, someone compiled credentials that were already circulating and released them under a new file name, which is why the source here is listed only as a Telegram upload rather than a named company breach.
