The Pjjkp.com Leak Exposed 3,965 U.S. Email and Password Pairs

HEROIC analysts found a combolist tied to the site pjjkp.com circulating on a Telegram channel in June 2026. The file contained 3,965 records pairing email addresses with plaintext passwords and the URLs each credential was used on, with the underlying data recorded as tied to the United States. Why this is dangerous: the passwords in this file are stored in plaintext, so anyone who obtains it can attempt to log in immediately, without needing to crack or decrypt anything. That makes the data usable right away by anyone who gets a copy of the file. What was exposed: email addresses, plaintext passwords, and associated URLs indicating which site each credential was tied to. Why this matters: with almost 4,000 accounts in this file, there is a real pool of people at risk. If any of them reused their password on other sites, attackers could use the same credentials to break into email, banking, or social media accounts through credential stuffing, which can lead to account takeover and identity theft. How combolists like this one work: a combolist bundles usernames or email addresses with passwords, typically gathered from earlier breaches, malware infections, or manual scraping, then packaged and shared or sold on Telegram channels and dark web forums. Because the credentials are already paired and organized, combolists let attackers automate large batches of login attempts across many sites at once. Check if you are affected: with nearly 4,000 records involved, it is worth checking whether your email address appears in this leak.
