The DIAMOND LogsCloud Leak: 6,100 Passwords Exposed. Yours Might Be One.

In June 2023, a threat actor on Telegram uploaded the second batch of DIAMOND LogsCloud stealer logs, this time exposing 6,100 records. Email addresses. Plaintext passwords. URLs from live browser sessions. All of it pulled directly off real people's devices by malware running without their knowlege. This is not a breach from a company that failed to secure its database. This is malware that was already on your computer, watching what you typed, and sending it to criminals. If your email appears in this dump, your password was already in someone else's hands before you ever knew anything was wrong.

Why This Is Dangerous

The word "plaintext" in a breach report should stop you cold. It means there is no encryption to crack, no hash to reverse, no technical barrier standing between an attacker and your account. They have the password exactly as you typed it. The 6,100 records in this DIAMOND LogsCloud batch represent 6,100 people who are potentially one credential-stuffing attempt away from losing access to their email, their bank, or their workplace systems. And because this dump has been circulating since June 2023, those attempts have already been happening for years.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (websites and services the infected user was logged into when malware captured their credentials)

Why This Matters

This is the second batch from the same DIAMOND LogsCloud threat actor, which tells you something important: this was not a one-time accident. This was a deliberate, organized campaign to harvest and distribute stolen credentials at scale. Combined with the first batch of 8,162 records (500PCS1), this actor exposed over 14,000 records in a single release window. Every person in either dataset who has not yet changed their compromised password is still at risk today. Stealer log dumps are not deleted from the dark web. They accumulat and get merged into massive complication files that attackers use for years.

How Stealer Logs Work

You do not have to do anything obviously wrong to become a stealer log victim. The malware spreads through phishing emails that look legitimate, through free software downloads, through browser extensions that seem harmless, and through cracked versions of paid applications. Once it lands on a device, it executes silently and immediately begins harvesting. Saved passwords in Chrome and Firefox, cookies that keep you logged into sites, credentials typed into forms in real time -- all of it captured, packaged, and transmitted to the attacker within minutes of infection. The DIAMOND LogsCloud batches are the end product of exactly this process, scaled across hundreds of infected machines.

Check If You Are Affected

HEROIC's free breach scanner searches more than 400 billion exposed records, including both batches of the DIAMOND LogsCloud stealer log dump. Type in your email address and find out in seconds whether your data is already circulating in criminal networks. If you are in this dump, the time to act is now -- not after an attacker uses your credentials to lock you out of your own accounts. Run your free scan and get ahead of it.
