Obsidian Project Infostealer Attack Leaks 6,222 Credentials

HEROIC found the Obsidian Project stealer log on 26-Apr-2026, a file exposing 6,222 records containing email addresses, plaintext passwords, and the URLs of services where those credentials were harvested from compromised devices. The log was uploaded to Telegram by a threat actor distributing infostealer output.

Why the Obsidian Project Breach Is Dangerous

The combination of email addresses, plaintext passwords, and service URLs gives attackers a ready-to-use attack toolkit. They can immediately attempt credential stuffing across email, banking, and e-commerce platforms without any additional processing.

What Was Exposed in the Obsidian Project Leak

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

Why This Obsidian Project 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.
