The DumpsCloud2 Leak: 16,787 Passwords, More Than a Sold-Out Arena

HEROIC analysts identified a stealer log file uploaded to a public Telegram channel on December 24, 2024, tagged "DumpsCloud2-logsdiller." It contained 16,787 records, more people than fit inside a sold-out mid-size arena, each pairing an email address with a plaintext password and the URL of the account that password opens, all pulled directly from malware-infected devices.

Why This Is Dangerous

Picture that many people in one building, and imagine every single one of them handing an attacker their email, their password, and the exact website it unlocks. That is effectively what this leak represents: a ready-to-use list of real, working logins with zero encryption standing in the way.

What Was Exposed in the DumpsCloud2 Leak

• Email addresses tied to infected devices
• Plaintext passwords stored and leaked with no encryption
• URLs identifying the exact accounts each login unlocks

Why This Matters

At this scale, even a small percentage of password reuse translates into a meaningful number of accounts an attacker can take over. Credential stuffing tools do not care how large the crowd is, they simply run every pair against target sites automatically, and every match can lead to financial fraud or identity theft for the person behind it.

How the DumpsCloud2 Stealer Log Was Likely Built

Stealer logs like this one come from infostealer malware that infects a device through a pirated download, a fake update, or a malicious attachment. Once running, it copies saved browser passwords, autofill entries, and live sessions into a text file, which is sent back to the attacker and eventually packaged and uploaded to channels like the one this data was found on.
