LogsDiller Stealer Log Exposes 1,630 Emails and Plaintext Passwords

HEROIC analysts identified a stealer log uploaded to Telegram on December 8, 2025, labeled "LogsDiller Cloud_Free_146_31." The file contained 1,630 records pulled straight from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts and services those passwords unlock. This is not a breach of one company's servers. It is the output of malware that quietly harvested saved logins from victims' own machines.

Why This Is Dangerous

The passwords in this log were stored in plaintext, meaning they were never encrypted or hashed. Anyone who gets hold of the file can use the listed email and password pairs immediately, with no cracking required. Because each credential is tied to the specific URL it unlocks, an attacker also has a ready map of exactly which site or service each stolen login opens.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

A leak of 1,630 records may look small next to headline breaches, but the risk per record is high. Criminals load stolen email and password pairs into automated tools and test them across banking sites, email providers, and social media, a technique known as credential stuffing. Anyone who reused one of these exposed passwords on another account faces a real chance of account takeover, identity theft, or financial fraud.

How Stealer Log Attacks Work

A stealer log is generated by information-stealing malware, often installed through a fake software download, a cracked application, or a malicious attachment. Once running on a device, the malware scans browsers and saved files for stored logins, cookies, and autofill entries, then packages everything into a log file. That file is then shared or sold in bulk, frequently on Telegram channels, sometimes given away for free as a sample to attract paying buyers, which appears to be exactly what happened here.

Check If You Are Affected

If you are concerned your credentials might be part of this or another leak, HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records in seconds. It only takes a moment to find out whether you need to change a password or enable two-factor authentication before an exposed credential becomes a compromised account.
