Search Your Email: OnionLabs Stealer Log Exposed 5,815 Records

In June 2023, a Telegram user uploaded a stealer log file known as 2 FACEBOOK ONIONLABS, exposing 5,815 records containing email addresses, plaintext passwords, and URLs. Stealer logs are compiled by malware that silently harvests credentials from infected devices, and this particular dump circulated through private Telegram channels before reaching a broader audiance. If you use Facebook or any service linked to your email, your login details may have been captured and shared without your knowledge.

Why This Is Dangerous

Stealer log breaches are uniquely hazardous because they capture credentials in the exact moment they are typed or stored. Unlike database breaches where passwords are hashed, stealer logs often contain plaintext passwords -- the actual characters you type. This means attackers do not need to crack anything. They can take your password and log in immediately. The 2 FACEBOOK ONIONLABS dump is particularly concerning because it specifically targetted Facebook-related endpoints, meaning accounts on one of the world's most widely used platforms are directly at risk.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API host data)

Why This Matters

When plaintext passwords leak alongside email addresses, the damage extends far beyond a single account. Most people reuse passwords across multiple sites. Attackers routinely run credential stuffing attacks, trying stolen login pairs against banking, shopping, and email services. A single stealer log entry can unlock dozens of your accounts. The 5,815 records in this dump represent real people whose digital lives became exposed the moment this file was uploaded to Telegram.

How Stealer Log Breaches Work

Stealer malware infects a device through phishing emails, malicious downloads, or compromised software installers. Once running, it silently records keystrokes, extracts saved browser passwords, captures cookies, and logs the URLs of sites visited. All of this data is bundled into a log file and sent to the attacker's server. The attacker then compiles these logs, sometimes sorted by platform, and sells or shares them in underground forums and Telegram groups. The 2 FACEBOOK ONIONLABS dump follows this exact pattern -- a Telegram user collected and uploaed Facebook-related credentials harvested by stealer malware.

Check If You Are Affected

HEROIC's free breach scanner searches over 400 billion records from known breaches and stealer log dumps, including incidents like this one. Enter your email address to see if your credentials appeared in the 2 FACEBOOK ONIONLABS leak or any other known breach. Early detection gives you time to change your passwords, enable two-factor authentication, and lock down your accounts before attackers can act.
