New Valid Bigdatacomboo: Exactly 163 Email and Password Pairs Leaked

In June 2025, a combolist titled 'New Valid Bigdatacomboo' was compiled and later uploaded to a Telegram channel by an individual user. HEROIC analysts confirmed the file contains exactly 163 records, each pairing an email address with a plaintext password and an associated login URL. Why This Is Dangerous: A small, precise list like this is often more dangerous than it looks, because it usually means the credentials were tested and verified as valid before being packaged for sale or free distribution. Every password in the file is stored in plaintext, so it can be used the moment someone downloads it. What Was Exposed: email addresses; plaintext passwords; associated login URLs. Why This Matters: With only 163 accounts involved, this isn't a headline-grabbing mega breach, but each person on this list faces the same real risk as someone caught in a much larger one: if a password was reused anywhere else, that account can be taken over through simple credential stuffing. How Combolists Work: A combolist is a curated list of working email-and-password combinations, often labeled 'valid' to signal to buyers that the credentials have already been checked. These lists are commonly assembled from older breaches and malware logs, then shared or sold in small batches on Telegram. Check If You Are Affected: Don't wait to find out the hard way. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including small, verified combolists like this one, so you can change any exposed password right away.
