Act Now: LogsDiller Stealer Log Exposes 4,410 Passwords

HEROIC analysts identified a stealer log dataset labeled LogsDiller Cloud_Free_398_68, uploaded to a public Telegram channel on December 8, 2025. The file contains 4,410 records, each pairing an email address with a plaintext password and a URL identifying which website the login was captured from. This data was not stolen from one company's servers, it was harvested directly from infected devices and packaged for other criminals to use immediately.

Why This Is Dangerous

There is no delay between this leak and real damage. The passwords are plaintext, meaning they work exactly as typed with no cracking needed, and the attached URLs tell an attacker precisely which site to try each login on. That combination turns a simple text file into a ready-to-use attack list, and every day it sits uncontested on Telegram is another day someone could be locked out of an account they do not even know is at risk.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

Because the URLs point directly to the affected sites, whoever holds this file does not need to guess where a credential works, they already know. That removes the usual trial and error of credential stuffing and speeds up account takeover, giving attackers a fast path to draining financial accounts, hijacking email, or using a compromised identity for further fraud.

How Stealer Log Breaches Work

A stealer log is generated when information-stealing malware infects a device and quietly copies saved passwords and browsing activity in the background, without the victim noticing. Every website the person logged into while infected ends up in the same file, which is why this leak likely spans many unrelated services rather than a single company. Once collected, the log gets uploaded to a Telegram channel like this one and shared or sold, often within days or weeks of the original infection, which is exactly what happened here.

Check If You Are Affected

Do not wait to find out the hard way. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, so you can immediately check whether your email or passwords have been exposed and change them before an attacker gets there first.
