11,368 Plaintext Passwords Leaked in SunCloudNew Breach

HEROIC analysts found a stealer log called SunCloudNew 1252 - 500 LogsFile uploaded to a Telegram channel on August 10, 2025. The file held 11,368 records taken from infected US devices, pairing email addresses with plaintext passwords and the URLs those logins access.

Why This Is Dangerous

The passwords in this file sit in plain text with nothing encrypting them, so anyone who obtains the file has a working login the moment they open it. Because each record is tied to the exact URL it was used on, attackers can move straight from file to account access without any cracking or guesswork.

What Was Exposed

• 11,368 individual records
• Email addresses
• Plaintext passwords
• Associated login URLs
• Endpoint data concentrated in the United States

Why This Matters

Plaintext credential leaks like this one rarely stay contained. Attackers run exposed email and password pairs through automated credential stuffing tools that test the same login across banking, retail, and email platforms. If you reused this password on another account, that account is exposed too, and the linked email address becomes a target for follow-on phishing.

How a Stealer Log Like SunCloudNew Gets Made

This is not a hacked company database, it is the output of infostealer malware that ran on individual victims' machines, usually delivered through a cracked download or a fake installer. The malware quietly copies saved passwords and cookies, then sends the haul back to its operator, who bundles harvests like this 11,368-record file and posts them on Telegram to build a following or sell to other criminals.
