Every Sector at Risk: TXTLOG_ALIEN 273M ULP Leaks 38.84M Logins

HEROIC discovered 38,840,192 records in BreachForums TXTLOG_ALIEN 273M ULP by txtlog_alien on 9 January 2025, leaking email addresses, plaintext passwords, and homepage URLs compiled from roughly 273 million raw stealer log entries. The dataset cuts across banking, retail, streaming, gaming, SaaS, and corporate logins because infostealer malware scrapes every saved password on a machine without discrimination.

Why This Stealer Log Is Dangerous Across Every Industry

This breach is dangerous because it is industry agnostic. A single infected laptop can leak the owner's personal webmail alongside corporate VPN, healthcare portal, online bank, and crypto exchange credentials, all in plaintext and paired with the exact login URL. That makes TXTLOG_ALIEN 273M ULP a universal starter kit for credential stuffing against any sector.

What Was Exposed in BreachForums TXTLOG_ALIEN 273M ULP by txtlog_alien

• 38,840,192 unique email addresses across consumer and business services
• Plaintext passwords with no hashing
• Homepage URLs mapping credentials to real login pages
• Evidence of widespread browser credential theft
• Combo list formatting ready for automated stuffing tools

Why This Matters

The file mixes personal and workplace logins on the same infected devices, which is why HR platforms, hospital patient portals, airline loyalty programs, and small business admin panels all see stuffing attacks spike after dumps like this drop. If your password has ever been saved in a browser on a compromised machine, it can now be tried against every service you have ever used.

How Stealer Logs Work

Stealer malware families such as RedLine, Lumma, StealC, and Vidar land on a victim through pirated software, malicious ads, or phishing attachments, then silently copy every browser-saved password, cookie, and autofill field. The data is exfiltrated to command-and-control servers, bundled into massive unified password list (ULP) drops, and posted on BreachForums by brokers like txtlog_alien.
