A Quiet Leak: LogDiller Log Exposes 2,889 Plaintext Passwords

LogDiller Stealer Log Quietly Exposes 2,889 Records

On December 8, 2025, HEROIC analysts came across a stealer log file, labeled "LogDiller Cloud_Free_22," sitting on a public Telegram channel without much notice. The file contained 2,889 records pulled from malware-infected devices, pairing email addresses with plaintext passwords and the URLs those credentials connect to.

Why This Is Dangerous

Leaks like this one rarely make headlines, which is exactly what makes them dangerous. There is no encrypted database for an attacker to break into, because the malware captured these passwords in plain, readable text directly from the victim's device. Paired with the exact login URL for each password, the data is ready to use the instant someone downloads it, with no fanfare required.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

A quiet leak still causes real damage. Attackers routinely feed stolen email and password combinations into automated credential stuffing tools, testing them against banking, email, and shopping accounts without anyone noticing until an account is already compromised. Anyone who reused this password elsewhere faces a genuine risk of account takeover, financial fraud, or identity theft, even if the leak itself never trends online.

How Small Stealer Log Leaks Add Up

Stealer logs come from infostealer malware, frequently bundled with pirated software, cracked games, or fake downloads. Once running on a device, the malware silently scans browsers and apps for saved passwords, then packages everything into a log file sent back to the attacker. Files like this one, even when relatively small, are routinely shared for free or sold cheaply on Telegram, quietly adding to the pool of credentials available to criminals.

Check If You Are Affected

Not every leak makes noise, but every leak is worth checking. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including quiet stealer logs like this one, so you can find out if your email address was affected and change any exposed passwords before someone else uses them.
