Hours After Upload: asad4100kkrre45b Leak Hits 13,854 Records

In August 2025, HEROIC analysts tracked a stealer log posted under the handle "asad4100kkrre45b" on a Telegram channel used for trading stolen data. The file contained 13,854 records, each combining an email address, a plaintext password, and the login URL where the credentials were captured.

A Fast-Moving Leak: The asad4100kkrre45b Timeline

Stealer logs like this one move quickly once they hit Telegram. The file first appeared, was flagged by HEROIC's monitoring systems within a short window, and by the time analysts finished cataloguing it, copies were already circulating in other channels. That speed is exactly what makes these leaks so hard to contain.

Every hour a log like this stays online, more people download it, meaning the risk to affected accounts grows with each passing moment rather than staying static like a one-time breach announcement.

Why This Is Dangerous

Because the passwords here were saved in plaintext, there is nothing standing between the data and a working login. An attacker does not need to guess, crack, or decrypt anything, they can simply try the exact combination on the exact site it came from.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Working credentials like these are the raw material behind credential stuffing attacks, where automated tools rapidly test stolen logins across many different sites at once. Anyone who reused a password from this log elsewhere is at risk of account takeover, which frequently opens the door to identity theft and financial fraud once an attacker gains access to email or banking accounts.

How Stealer Logs Work

Stealer malware infects a victim's device silently, often through a fake download or cracked application. Once active, it pulls saved passwords, cookies, and autofill data straight out of the browser and compiles everything into a structured log file, exactly the kind seen here.

These logs are then dropped into Telegram channels where buyers and collecters trade access. Because the data was harvested directly from a real, active session, it tends to be far more reliable than older, recycled password dumps.

Check If You Are Affected

Do not wait to find out if your credentials are part of a leak like this. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records, including stealer logs pulled straight from Telegram. The scan takes only seconds and could catch a problem before an attacker does.
