How the spiderLogs FREE Stealer Malware Led to 27,471 Stolen Logins

HEROIC analysts identified a stealer log file that appeared on Telegram on December 19, 2022, uploaded by an anonymous user under the name spiderLogs FREE. The file contained 27,471 records harvested from infected endpoint devices. Each record included an email address, a plaintext password, and a URL. The data was made freely available on the platform, meaning any attacker could download and use it without payment. Our team verified this breach and added it to the HEROIC database for public protection.

Why This Is Dangerous

Making this kind of data freely available is what makes it especially risky. Most stolen credential files are sold, which limits the number of people who have access. Calling it free and sharing it openly means thousands of threat actors may have downloaded and used this file over the years since December 2022. Every email and password pair in this log has potentially been tried against dozens of services already.

What Was Exposed in the spiderLogs FREE Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs and API Host Endpoints

Why This Matters for Your Security

A freely distributed stealer log from 2022 does not expire. Attackers still use old credential lists because most people never change their passwords after a breach they don't know about. If your email and password appeared in this file and you have not changed those credentials, you are still at risk today. Credential stuffing, account takeover, and identity theft are all realistic outcomes from a file like spiderLogs FREE being circulaited this widely.

How the spiderLogs FREE Stealer Malware Worked

Infostealer malware like the kind used to build this log typically arrives through a phishing email, a fake software download, or a malicious browser extension. Once running on a device, it scans for saved passwords in browsers like Chrome and Firefox, intercepts login form submisions, and reads stored credentials from applications. The collected data gets packaged into a log file and sent back to the attacker automatically. The victim gets no warning and usually finds out only when their accounts start behaving strangely.
