3,972 Email-Password Pairs Stolen in the Logssss Infostealer Attack

HEROIC found the Logssss stealer log on 19-Jul-2023, a file exposing 3,972 records containing email addresses, plaintext passwords, and the URLs of services where those credentials were harvested from compromised devices. The log was shared on Telegram in July 2023.

Why the Logssss Breach Is Dangerous

Infostealer malware compiled these 3,972 records from infected machines, capturing credentials directly from browsers and applications before packaging the data for distribution on Telegram. Attackers can use these pairs in automated login attacks across any service where victims reuse passwords.

What Was Exposed in the Logssss Leak

• Email addresses
• Plaintext passwords
• URLs (the exact services where credentials were captured from infected devices)

Why This Logssss Data Puts You at Risk

Credential stuffing, account takeover, identity theft, and financial fraud are all immediate risks when email-password pairs are exposed in plaintext. Attackers automate login attempts across hundreds of platforms, and victims typically have no warning until accounts are compromised.

How Stealer Log Works

Infostealer malware spreads through phishing campaigns, trojanized software, and malicious downloads. After infecting a device, it harvests stored credentials from browsers and apps, then sends the data to attacker-controlled infrastructure. The resulting logs are packaged and distributed through Telegram channels and dark web forums.
