If You Reuse Passwords, the MetaCloudVipNew Leak Should Worry You

HEROIC analysts found a stealer log titled "MetaCloudVipNew 400 PC" that a Telegram user uploaded on November 12, 2025. The file contained 13,775 records tied to United States based accounts, including email addresses, plaintext passwords, and the URLs of the login pages those credentials belonged to.

Why This Is Dangerous

If you reuse the same password across multiple accounts, a leak like this one should worry you more than most. The passwords inside are stored in plaintext, meaning there is no encryption standing between an attacker and a working login, and the matching URL for each account tells an attacker exactly where to try it. Once one password is confirmed to work, an attacker's next move is testing that same password everywhere else you might have an account.

What Was Exposed in the MetaCloudVipNew Leak

• Email addresses
• Plaintext passwords
• URLs of the associated login accounts

Why This Matters for the 13,775 Affected Accounts

An email, password, and login URL bundled together gives an attacker everything needed to attempt account takeover with no guesswork. If anyone among these 13,775 accounts reused their password elsewhere, the same combination can be tested against banking, email, and shopping sites within minutes through automated credential stuffing tools. From there, the risk extends into identity theft and financial fraud, since a compromised email account is often the key to resetting passwords on everything else tied to it.

How a Stealer Log Like MetaCloudVipNew Gets Built

A stealer log is the output of malware that infects a device and quietly harvests whatever login data it can find, typically credentials saved in a browser, autofill entries, and active session data. The infected machine sends this haul back to the attacker, who compiles it into a labeled batch, such as the "400 PC" naming seen here, referring to the number of infected machines the data was pulled from. These files are then posted to Telegram channels or dark web forums. Because the theft happens on the victim's own device rather than through a breach of a company's servers, a single stealer log can expose credentials for dozens of unrelated sites at once.

Check If You Are Affected

If you are based in the United States, or think your credentials could have been swept up in a stealer log campaign, checking your exposure now is worth doing, especially if you know you reuse passwords. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer log dumps like this one, to tell you whether your email address has surfaced in a known breach. If it has, change the affected password immediately, along with any other account where you reused it.
