Your Data May Be in the MetaCloudNew Part 1 Leak of 20,095 Records

HEROIC analysts identified this stealer log, titled "MetaCloudNew 4100 PCs.part1," uploaded to a Telegram channel on August 14, 2026. The file contains 20,095 records combining email addresses, plaintext passwords, and the URLs those logins were used on.

Why This Stealer Log Is Dangerous

With over 20,000 records stored in plaintext, this log gives an attacker a large, immediately usable set of login pairs. There is no encryption to break, just an email, a password, and the site it belongs to, ready to be tried against real accounts.

What Was Exposed in the MetaCloudNew Log

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

A dataset this size is well suited to credential stuffing, where automated scripts run stolen logins against dozens of popular sites at once. Because password reuse is so common, a leak like this can lead directly to account takeover, and from there to identity theft or financial fraud.

How This Stealer Log Was Likely Created

Logs like this typically originate from infostealer malware bundled into cracked software, fake installers, or malicious downloads. Once it infects a machine, the malware pulls saved passwords and autofill data from the browser, along with the associated URLs, and reports everything back to the attacker who assembled this log, apparently harvested from around 4,100 infected PCs.
