How Stealer Malware Produced the TXTLOG_ALIEN 104M ULP Leak

HEROIC discovered 20,314,274 records in BreachForums TXTLOG_ALIEN 104M ULP by txtlog_alien on January 12, 2025, leaking email addresses, homepage URLs, and plaintext passwords pulled from a 104 million line aggregated stealer log posted to BreachForums.

Why This Stealer Log Dump Is Dangerous

Aggregated stealer logs are the oxygen for modern account takeover. With 20.3 million unique emails and plaintext passwords sitting on BreachForums, any reused credential becomes an immediate pivot point for banking fraud, SaaS intrusion, and identity theft.

What Was Exposed in BreachForums TXTLOG_ALIEN 104M ULP by txtlog_alien

• 20.3 million unique email addresses deduplicated from 104M log lines
• Plaintext passwords ready for direct credential stuffing
• HomePage URLs mapping each login pair to its exact target service

Why This Matters

This dump is specifically advertised as a combo list, which means it has been sanitized and deduplicated. That extra work makes every record more effective for attackers and raises the real-world hit rate of automated credential-stuffing campaigns.

How Aggregated Stealer Dumps Are Built

Here is the step-by-step. Infostealer malware like RedLine and Lumma lands on victim machines through cracked software or phishing, exfiltrates saved browser credentials, and uploads the logs to operators. Aggregators such as txtlog_alien combine thousands of individual logs, deduplicate them by email, and post the final combo file on BreachForums for credential-stuffing buyers.
