The SpiderLogs FREE Leak Gave Hackers 22,052 Ready-to-Use Credentials

HEROIC analysts documented the SpiderLogs FREE stealer log on December 17, 2022, when it was uploaded to a public Telegram channel by an anonymous user. The file contained 22,052 records, each entry pairing an email address with a plaintext password and an associated URL pointing to the service where the credential was active. The combination of cleartext passwords and direct service URLs is what makes this particular log so actionable for attackers -- there is no decryption step, no guesswork, and no delay between obtaining the file and beginning an attack. HEROIC flagged this log as a high-priority credential exposure at the time of discovery.

Why This Is Dangerous

The SpiderLogs FREE dataset hands attackers a complete credential package. Every record includes the exact URL where the password works, the email used to log in, and the password itself in readable plaintext. A threat actor does not need specialized tools or technical knowledge to exploit this data. They can simply open the file, copy a credential pair, and attempt a login. At scale, automated tools can process all 22,052 records in a matter of hours, testing each combination across hundreds of popular platforms. The free distribution on Telegram means this data reached a wide audience of potential attackers, not just a single buyer.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (service endpoints where credentials were active)

Why This Matters

Credential exposure at this scale creates a cascade of risk that extends well beyond the original services captured in the log. Credential stuffing attacks use automated tools to test stolen username and password pairs against banking platforms, email providers, e-commerce sites, and social media. A password reused across even two services doubles the attacker's opportunity. Account takeover then opens the door to identity theft -- attackers can change recovery emails, lock out legitimate owners, and extract personal and financial information. For individuals whose credentials appear in this log, the window to take protective action closed in December 2022. Those who have not yet changed affected passwords remain at risk today.

How Stealer Logs Work

Stealer logs originate from infostealer malware -- programs designed to quietly harvest credentials from infected devices without the user's knowledge. Victims typically encounter infostealers through malicous email attachments, pirated software downloads, or trojanized browser extensions. Once running on a device, the malware scans for saved passwords in browsers like Chrome and Firefox, extracts session cookies, and records any credentials typed or autofilled in web forms. The collected data is bundled into a structured log and sent to a remote server controlled by the attacker. From there, logs are sold on dark web markets or, as in this case, distributed freely on Telegram channels to attract followers and build reputation within criminal comunities. The victim often has no idea their credentials were stolen until they discover unauthorized access to one of their accounts.

Check If You Are Affected

If your email address was captured by the SpiderLogs FREE stealer malware, your credentials may have been in circulation since December 2022. HEROIC maintains a breach search database of over 400 billion records, including stealer log data from thousands of known incidents. Visit heroic.com to search your email address and determine wether your credentials are exposed. Changing your passwords and enabling two-factor authentication on all accounts is the most immediate step you can take to reduce your exposure.
