The lionking_cloud 499count Data Leaked in 2025. Now It’s Public.

The credentials in the lionking_cloud 499count stealer log were stolen in July 2025. For months, that data circulated in private Telegram channels, visible only to criminal actors who traded it among themselves. Now it has gone public. That means 26,024 records containing plaintext passwords, email addresses, and URLs are no longer confined to underground networks -- they are accessible to a far wider pool of bad actors, and the window for victims to get ahead of the damage is closing fast.

Why This Is Dangerous

The transition from private Telegram channels to public exposure dramatically increases the risk for every person in this file. When stealer log data circulates privatley, it is typically used by a small group of sophisticated attackers. Once it goes public, the same data is weaponized by thousands of opportunistic criminals running automated credential stuffing tools. Accounts that survived the initial private phase of exposure are now facing a much broader wave of attack attempts.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (showing which services each victim used)

Why This Matters

July 2025 to public exposure represents months during which victims had no warning. If your email appears in the lionking_cloud 499count file, your password was known to criminals long before this report was written. The plaintext format means no decryption was needed -- attackers could use your credentials immediately upon obtaining the file. And because URLs are included, they knew exactly which accounts to target first. Every day that passes without a password change is another day that risk accumulates.

How Stealer Log Breaches Work

Stealer logs like lionking_cloud 499count are created by info-stealing malware that infects devices through phishing emails, malicious software, or compromised websites. Once active, the malware silently harvests saved passwords from browsers, captures keystrokes durring login sessions, and extracts session cookies that allow attackers to bypass authentication entirely. The collected data is packaged into a numbered log file and uploaded to Telegram, where operators like the one behind lionking_cloud sell or distribute the logs to other criminal actors before eventually releasing them more broadly.

Check If You Are Affected

HEROIC's free breach scanner searches more than 400 billion exposed records -- including the lionking_cloud 499count stealer log -- to tell you instantly whether your email is in this file. The data went public. The threat is real. Search your email now and change your passwords before the next login attempt uses your stolen credentials.
