One Telegram File, 32,164 Records: Inside the Mail Access Hits Leak

HEROIC analysts identified a file called "Mail Access Hits" circulating on Telegram on April 21, 2026. The upload contains 32,164 records made up of email addresses paired with plaintext passwords and the login URLs they belong to, a batch of working email account logins.

Why the Mail Access Hits Combolist Is Dangerous

A combolist like this one is dangerous precisely because it requires no extra work from an attacker. The passwords are stored in plaintext, so there is no encryption to crack and no hashing to break. Anyone who downloads the Mail Access Hits file can immediately start testing the 32,164 email and password pairs against email providers, banking portals, social media platforms, and online stores.

This kind of automated testing is called credential stuffing, and it works because so many people reuse the same password across multiple accounts. If your email and password appear in this file and you have used that same password anywhere else, an attacker does not need to guess anything. They just try the combination and see what opens.

• Plaintext passwords
• Associated login URLs

Why the Mail Access Hits Leak Puts Your Accounts at Risk

Once credentials from a combolist like Mail Access Hits start circulating, the risk moves quickly beyond the original account. Attackers use working email and password pairs to attempt logins on banking sites, retail accounts, and email providers, since a compromised email inbox can be used to reset passwords on almost every other account tied to it.

With 32,164 records in this single file, the scale means a large number of email accounts could be tested in a short amount of time. An attacker who gets into your inbox can find bank statements, tax documents, and password reset links. An attacker who gets into a reused password on a shopping site can place orders or drain stored payment methods.

How the Mail Access Hits Combolist Was Likely Built

Combolists labeled "mail access" or "hits," like this one, are usually assembled by combining older leaked data from multiple sources, credentials harvested by malware, or details gathered through phishing pages, then testing them to confirm the email logins still work before merging them into a single list. The person who uploaded this file to Telegram did not necessarily breach a single company. Instead, they compiled working credentials from various origins and packaged them for other threat actors to use or resell.

This is a common pattern in the criminal underground: raw or previously leaked credentials get repackaged into "fresh" combolists and shared or sold on Telegram channels and dark web forums, giving them a second life long after the original exposure.

Check If You're Affected by the Mail Access Hits Leak

If you think your email address could be part of this combolist, or any of the other breaches we track, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records. Run a scan to see whether your email and password appear in this leak or any other, and if they do, change that password everywhere you have reused it.
