Your Data May Already Be Compromised. The TXTLOG_ALIEN – 699 Breach Exposed 12 Million Records.

HEROIC analysts discovered the TXTLOG_ALIEN - 699 stealer log circulating on a Telegram channel on January 21, 2025. The dataset contained approximately 52 million total records, with 12,362,857 unique email addresses extracted from the file. Every record pairs an email address with a plaintext password and a homepage URL that identifies the site from which the credential was taken. This log was distributed via Telegram, meaning it was publicly accessible to any actor who followed the channel at the time of posting.

Why Plaintext Passwords in a Telegram File Are a Serious Problem

Hashed passwords, even weak ones, require some processing before they can be used. Plaintext passwords require nothing. Every password in this file can be copied and used directly against a login page. And because Telegram channels distribute files to all subscribers instantly, the 12 million credentials in TXTLOG_ALIEN - 699 were in the hands of numerous threat actors within minutes of the post going live. The homepage URLs included in the log tell attackers exactly where each credential was originally active, creating a prioritized target list alongside the stolen data itself.

What Was Exposed in the TXTLOG_ALIEN - 699 Log

• Email addresses (approximately 12 million unique)
• Plaintext passwords associated with each email
• Homepage URLs identifying the sites where credentials were captured

Why This Matters: The Chain from Stealer Log to Identity Fraud

A stolen email and plaintext password is not just a problem for one website. Attackers feed these pairs into credential stuffing software that tests them across banking portals, email providers, ecommerce sites, and corporate systems. Where passwords are reused, access is immediate. Once inside an email account, an attacker can request password resets across every connected service, triggering a cascade: financial account access, fraudulent purchases, and impersonation. For business email addresses, the exposure escalates further, potentially giving attackers a foothold inside a company network.

How Telegram Has Become a Distribution Hub for Stealer Logs

Infostealer malware collects saved browser passwords, session tokens, and autofill data from infected devices. The infections typically arrive through malicious downloads, fake software cracks, or phishing links. The harvested data is assembled into logs and sold or freely shared by threat actors on Telegram, which has become a preferred distribution channel because it offers large file transfers, anonymity, and instant reach to large audiences. The ALIEN series has followed this model across hundreds of sequential releases, flooding the ecosystem with compromised credentials throughout early 2025.
