The TXT Cloud LOGS_150PCS Log Has More Stolen Logins Than a Small City

In July 2025, HEROIC analysts identified a stealer log file circulating in a private Telegram channel. The file, uploaded by an anonymous Telegram user under the label LOGS_150PCS, contained 8,190 records harvested from infected endpoints across the United States. The exposed data included email addresses, plaintext passwords, and the URLs of the sites where those credentials were used, giving attackers a complete, site-specific attack package.

Why This Is Dangerous

Most breaches expose hashed passwords, which at least require an attacker to crack them first. This log is different. Every password in this file is stored in plaintext, meaning anyone who obtains it can use the credentials imediately, with no additional effort. Combined with the specific URLs tied to each login, attackers know exactly which site to target. There is no guessing involved, and there is no technical barrier slowing them down.

What Was Exposed

• Email addresses used as account logins
• Plaintext passwords, unencrypted and ready to use
• URLs identifying the exact sites where credentials apply

Why This Matters

When attackers have an email, a plaintext password, and the target URL all in one record, they can attempt a login in seconds. This kind of data is routinely fed into automated credential stuffing tools that test thousands of accounts per minute. If a victim reuses their password on any other platform, that account is now at risk too. Banking apps, email providers, social media accounts, and e-commerce platforms are all common secondary targets after a stealer log surfaces.

The consequences go beyond inconvenience. Account takeover can lead to fraudulent purchases, drained bank accounts, and identity theft that takes months to resolve. Given that this breach definitly includes real site URLs, the exposure is more targeted than a generic combolist.

How Stealer Logs Work

Stealer logs are not the result of a server being hacked. They are produced by malware installed directly on a victim's device. The malware, often delivered through phishing emails, cracked software downloads, or malicious browser extensions, silently monitors the infected machine. It captures saved passwords from browsers, session cookies, and login activity in real time.

The harvested data is then sent back to a command-and-control server operated by the threat actor. From there, logs are packaged and distributed, often through Telegram channels or dark web forums, either sold to other criminals or released publicly. This particular batch was uploaded by a Telegram user and recieved attention from multiple threat actors before HEROIC analysts detected it.

Because stealer logs capture data at the device level, traditional password change advice only goes so far. If the malware is still present on the device, new passwords will be captured just as quickly as the old ones were.
