Our Analysts Found 1,095 Stolen Logins: 1100 .UA Mail Access Dump

In February 2026, HEROIC analysts identified a stealer log titled 1100 .UA Mail Access, uploaded to a Telegram channel and exposing 1,095 records. The file contains email addresses, plaintext passwords, and the URLs tied to .UA mail accounts pulled from infected devices.

Why the 1100 .UA Mail Access Log Is Dangerous

Because the passwords are stored in plaintext and already paired with the mail service each one unlocks, an attacker does not need to guess or crack anything. Anyone with a copy of this file can attempt to log directly into each of the 1,095 mail accounts listed.

What Was Exposed in the 1100 .UA Mail Access Dump

• Email addresses
• Plaintext passwords with no encryption
• URLs identifying the mail access point each credential pair unlocks

Why This Matters

Email accounts are often the master key to someone's digital life, used to reset passwords for banking, shopping, and social media accounts. If any of the 1,095 accounts in this log are still active, an attacker who logs in could reset passwords on other services, read sensitive messages, or use the account to send convincing phishing emails.

How This Type of Mail Access Log Gets Created

Stealer malware infects a device, often through a pirated download or malicious attachment, and quietly copies saved passwords and login pages straight from the browser. Because this batch focuses specifically on mail access, the credentials were likely filtered and grouped afterward before being shared in a Telegram channel under this label.

Check If You Are Affected

If you use a .UA email address, it is worth checking whether your account is one of the 1,095 records exposed here. HEROIC's free breach scanner searches a database of more than 400 billion leaked records so you can find out what's exposed and act quickly.
