The GitHub-Tagged Combolist Gives Hackers 5 Working Logins

HEROIC analysts found a small combolist labeled "github" shared by a Telegram user in May 2026. The file contained just 5 records pairing email addresses with plaintext passwords and associated URLs. This is one of the smallest leaks HEROIC has tracked, but a small record count does not mean the risk is small for the individuals involved. Why this is dangerous: because the passwords are stored in plaintext, whoever holds this file can try logging in immediately using the exact credentials, with no cracking required. For the 5 people whose data appears here, that means their login information is fully usable by anyone who has the file. What was exposed: email addresses, plaintext passwords, and associated URLs tied to each set of credentials. Why this matters: even with only 5 records, the risk to those individuals is real. If any of the passwords are reused on other accounts, such as email, code repositories, or financial services, attackers can attempt the same credentials elsewhere through credential stuffing, potentially leading to account takeover or identity theft. How combolists like this one work: a combolist bundles usernames or email addresses with passwords, typically gathered from previous breaches, malware infections, or manual collection, then labeled and shared or sold on Telegram channels and dark web forums. Even small combolists like this one circulate the same way as larger ones, often bundled together with other files by the people distributing them. Check if you are affected: with any leak, however small, it is worth confirming your information was not included. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records so you can find out quickly and take action if needed.
