Inside the Cheatbreaker Logs: How Infostealer Malware Harvested 3,707 Passwords

HEROIC analysts documented the cheatbreaker cloud base stealer log after it surfaced in a Telegram channel in July 2023. The dataset contained 3,707 records tied to what appears to be a cloud-based gaming or anti-cheat service, with each record including a plaintext password, an email address, and the URL of the service where the credential was captured. Our breach intelligence team verified the records as authentic and originating primarily from United States-based users.

Why This Is Dangerous

Gaming accounts are a frequent target for credential thieves because players often reuse the same password across gaming platforms, email accounts, and even banking apps. A stolen login from a gaming service is rarely just about the game. It is a key that can unlock a lot of other doors. Plaintext passwords are the most dangerous form of stolen credential -- there is no cracking required, no guessing, no extra work. The attacker simply types in the email and password and gets in. With URLs also included, they know exactly which services to target first.

What the Cheatbreaker Cloud Base Log Exposed

The 3,707 records in this dataset contained the following data for each compromised account:

• Email addresses (used as the primary account identifier across gaming platforms and cloud services)
• Plaintext passwords (unencripted, ready-to-use credentials captured directly from infected machines)
• URLs (the specific web adresses where each credential was stolen, revealing which platforms were targeted)

Why the Cheatbreaker Cloud Base Breach Matters for Gaming and Cloud Users

The name "cheatbreaker" points to software used in competitive gaming environments -- tools that monitor player behavior, require account logins, and often run with elevated system permissions. This creates a concerning attack surface. If an infostealer was able to harvest credentials from devices running this kind of software, it likely also captured session tokens, API keys, and saved browser passwords for entirely unrelated services. The breach is small in record count, but the quality of the data -- active plaintext credentials with matching URLs -- means every one of these 3,707 people is at risk of account takeover on multiple platforms. Cloud service credentials in particular can provide access to files, contacts, and stored payment methods.

Inside the Cheatbreaker Logs: How Infostealer Malware Harvested These Passwords

Infostealer malware is a type of program that installs itself on a victim's computer without their knowlege and quietly collects sensitive information in the background. It typically arrives through game mods downloaded from unofficial sources, cracked software, or phishing links shared in gaming communities. Once running, the malware scrapes saved passwords from web browsers, captures keystrokes, copies session cookies, and harvests any credentials stored in the operating system. All of this data is sent back to the attacker and organized into a log file. The cheatbreaker cloud base log is exactly this kind of file -- a structured archive of credentials pulled from real users' devices, later uploaded to a Telegram channel where it was sold or shared with other criminals. This is not a database hack. The victim's own computer did the work.

Check If Your Accounts Were Part of This Breach

Even though this log contains under 4,000 records, your email address could still be in it. HEROIC's free breach search covers over 400 billion compromised records across thousands of breaches. Enter your email to check if this or any other known breach exposed your credentials. If you find a hit, update your password on the affected service immediately and anywhere else you used the same password. Enabling two-factor authentication is the single most effective step you can take to stop account takeover even if your credentials are already in criminal hands.
