The TXTLOG_ALIEN 752 Stealer Log Quietly Appeared on Telegram With 13.8 Million Passwords

HEROIC analysts found the TXTLOG_ALIEN - 752 stealer log on a Telegram channel on February 16, 2025. The file contained approximately 50.4 million lines of data and exposed 13,843,556 unique records, each pairing an email address with a plaintext password and a homepage URL. It is one log in a numbered series that continues to grow, and the scale of this particular entry places it among the larger credential dumps circulating in early 2025.

What Attackers Can Do Immediately With 13.8 Million Plaintext Passwords

Plaintext passwords require no cracking. Every email-password pair in TXTLOG_ALIEN - 752 is actionable the moment someone opens the file. Attackers typically feed these pairs into automated credential stuffing tools, testing them against popular banking sites, email providers, streaming services, and corporate login portals. The homepage URLs included in this dataset go further: they identify the specific platform where each credential was harvested, so attackers know where to start without guessing. With 13.8 million pairs to work through, even a low success rate translates to hundreds of thousands of compromised accounts.

What Was Exposed

• Email Address: The login identifier tested against every service that uses email-based authentication
• Plaintext Password: The original password in readable form, instantly usable without decryption
• Homepage URL: The source website for each credential, giving attackers a precise first target

Why This Matters: Credential Stuffing, Account Takeover, and the Password Reuse Problem

Most people reuse passwords. Attackers know this and rely on it. A credential harvested from one site, paired with an email address, becomes a key that opens doors across dozens of other platforms. TXTLOG_ALIEN - 752 exposed 13.8 million of those keys in a single log. Once credential stuffing campaigns begin, the downstream effects include unauthorized purchases, locked-out account owners, unauthorized wire transfers, and hijacked email accounts used to launch further phishing campaigns against contacts. The damage is rarely limited to the platform where the original password was taken.

How the TXTLOG_ALIEN 752 Stealer Log Was Created

Stealer logs are produced by infostealer malware, software designed to silently harvest credentials from infected machines. The malware records usernames, passwords, and associated URLs directly from browser password managers and autofill data, then transmits the collected data to the attacker's server. The results are organized into structured log files and distributed through Telegram channels, where they are traded, downloaded, and used by other threat actors. The TXTLOG_ALIEN series follows a consistent numbering convention (751, 752, 753, and beyond), indicating a sustained operation rather than a single opportunistic event. Each log in the series represents a fresh batch of credentials from newly infected systems.
