Your Data May Be Exposed: Apostle Private 15 Leaked 1,261 Logins

HEROIC analysts identified a combolist file labeled "Apostle Private 15" uploaded to Telegram on 27 October 2025. The file contained 1,261 records pairing email addresses with plaintext passwords, along with associated URLs tied to the accounts. That is over a thousand ready-to-use logins now circulating from a single upload.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, no cracking or specialized tools are required to use them. Anyone with the file can read each email and password pair directly and attempt to log in immediately, either to the original account or to any other service where the same password might be reused.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

Reused passwords are what turn a single leak into a wider problem. Attackers load lists like this into automated tools and test the credentials against banking sites, email providers, and social media accounts through credential stuffing. With over 1,200 records here, even a modest success rate can lead to multiple account takeovers, identity theft, and financial fraud.

How Combolist Leaks Work

A combolist is a compiled text file of email and password pairs gathered from earlier breaches, phishing campaigns, or malware infections, then bundled together and shared on platforms like Telegram under labels such as "Apostle Private 15." Assembling one does not require hacking a company directly. It requires collecting already-stolen credentials from multiple sources into a single file, which is why these leaks can surface with little detail about where the data originally came from.

Check If You Are Affected

With over 1,200 accounts in this dataset, it is worth checking your own exposure. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records in seconds and shows you what to do next if you are affected.
