Search Your Email: CRYPTON_LOGS 299PCS Exposed 7,209 Accounts

HEROIC analysts flagged an unusual stealer log upload circulating on a public Telegram channel on December 19, 2024. The dataset, labeled CRYPTON_LOGS 299PCS, contained 7,209 records harvested from compromised endpoints across the United States. What made this particulary alarming was the presence of plaintext passwords alongside active URLs, indicating the malware had captured live login credentials rather than dormant stored data. The combination of email addresses, passwords, and service URLs creates an immediately actionable package for anyone looking to break into accounts.

Why This Is Dangerous

When attackers get their hands on a stealer log like CRYPTON_LOGS 299PCS, they do not need to crack anything. The passwords are already in plaintext, ready to copy and paste. A bad actor can take an email and password pair, try it against Gmail, PayPal, a banking app, or a corporate VPN, and be inside in seconds. The associated URLs in this log tell attackers exactly which services the victims were using, making it trivial to prioritize which accounts to attack first. Seven thousand compromised credential sets, even from a single log file, can fuel weeks of fraudulent activity.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (service and application endpoints)
• API host information
• Endpoint identifiers from compromised devices

Why This Matters

Credential leaks of this type feed directly into some of the most damaging attack chains in cybersecurity. With a valid email and password, attackers can attempt credential stuffing across dozens of platforms simultaneously, exploiting the fact that many people reuse passwords. Successful logins lead to account takeover, where attackers drain stored payment methods, hijack social media profiles, or pivot into corporate systems using the same credentials. Identity theft is another real risk, particularly where email access allows attackers to reset passwords on banking and government accounts. Even a few successful logins out of 7,209 attempts can yield significant financial fraud or long-term access to sensitive systems.

How Stealer Log Breaches Work

Stealer logs are generated by a category of malware known as infostealers or credential stealers. These programs, often delivered through phishing emails, malicious downloads, or compromised software installers, run silently on a victim's machine. They scan browser credential stores, saved passwords, and autofill data, recording the exact URL each credential belongs to, then package everything into a structured log file. That file gets transmitted back to the attacker's infrastructure and frequently ends up for sale or free distribution on Telegram channels and dark web forums. The CRYPTON_LOGS 299PCS dump follows this exact pattern: malware infected endpoints, harvested active credentials, and an anonymous Telegram user posted the resulting log for other threat actors to exploit. The whole process can happen in minuts, often without the victim ever noticing.

Check If You Are Affected

If your email address was active in late 2024, there is a chance your credentials appear in this dataset or others like it. HEROIC maintains a database of over 400 billion breached records, one of the largest collections of compromised credential data in the world. You can search your email address at heroic.com to find out whether your information has appeared in a known data breach, including CRYPTON_LOGS 299PCS. If you find a match, change your passwords immediately, enable two-factor authentication on all important accounts, and avoid reusing the same password across multiple services.
