Email Users Targeted as MAIL Stealer Log Leaks 225,406 Records

A file simply titled "MAIL" surfaced on Telegram on January 21, 2026, targeting exactly what its name suggests, email accounts, with 225,406 records of stolen login data packed inside.

Why This Is Dangerous

Email accounts sit at the center of almost everyone's digital life, they're used to reset passwords, receive sensitive documents, and confirm identity on dozens of other services. A leak specifically targeting mail accounts, like this one, hits at the weakest link in a person's entire online security.

What Was Exposed

• 225,406 email addresses along with their passwords
• Plaintext passwords with no encryption in place
• URLs confirming which mail service each account belongs to

Why This Matters

Anyone whose email account gets compromised is at risk of a domino effect. Once an attacker controls your inbox, they can request password resets on your bank, your social media, and any other account tied to that address, often before you even relize your email password was ever exposed.

How This Mail Targeted Leak Happened

Stealer malware doesn't discriminate by account type while it's harvesting data, but files like this one get sorted and labeled afterward based on what kind of credentials they contain. In this case, whoever built the file specifically pulled out email logins, wich made it more valuable to buyers looking to target inboxes directly.

Check If You Are Affected

Since email accounts unlock so much else, checking your exposure here is neccessary, not optional. HEROIC's free scanner searches over 400 billion leaked records for free, so you can confirm in seconds if your email address is part of the MAIL file.
