The Antipublic Leak Means Someone May Be in Your Accounts

In early February 2023, HEROIC analysts identified a stealer log posted to Telegram titled 13k Antipublic, containing 13,179 exposed records. Each entry pairs an email address with a plaintext password and the URL of the login page it opens, consistent with malware that harvests saved credentials directly from an infected browser.

An Antipublic Leak Means Someone Could Already Be in Your Accounts

The term Antipublic refers to stolen credential collections deliberately kept out of free public leak databases and sold or traded privately instead, meaning the accounts inside are less likely to have been found and reset already. For anyone in this file of 13,179 records, that privacy is exactly what makes the threat more immediate: an attacker could be quietly testing or already using these logins while the victims remain unaware.

What Was Exposed in the Antipublic File

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Because antipublic collections are kept private rather than dumped publicly, the credentials inside often stay valid for longer, giving attackers more time to attempt credential stuffing and account takeover before victims change their passwords. Anyone who reused a password from this file on other services also faces increased risk of financial fraud and identity theft.

How an Antipublic Stealer Log Gets Made

Infostealer malware infects a device through a cracked download, pirated software, or malicious attachment, then silently extracts every saved password and login URL from the browser. Sellers who label a file Antipublic deliberately avoid posting it to free leak forums, choosing instead to sell or trade it privately on Telegram to a smaller group of buyers, which keeps the credentials valuable for longer.

Check If You Are Affected

Since antipublic data rarely surfaces in mainstream leak checkers, it is worth checking your exposure directly. HEROIC's free breach scanner searches a database of more than 400 billion compromised records, including private leaks like this one, so you can confirm in seconds whether your email and password were exposed.
