The 1800_iCloud_KRDCLOUD Leak Went Quiet, Then 1,792 Logins Surfaced

HEROIC analysts identified a combolist named "1800_iCloud_KRDCLOUD" that surfaced on Telegram on 15 July 2026. The file had likely been assembled some time before it was posted, and it contains 1,792 records pairing email addresses with plaintext passwords and the URLs of the accounts they unlock.

Why This Is Dangerous

Data like this often sits unnoticed in private channels for weeks or months before it gets shared more widely, giving attackers a head start over the people it affects. Because the passwords here are stored in plaintext, whoever holds the file can log in with them immediately once they get access.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the account each credential pair belongs to

Why This Matters

The longer stolen credentials circulate before becoming public, the more people may have already used them for unauthorized logins. If you are among the 1,792 accounts in this file and have not changed your password recently, you should treat that password as compromised right now.

How Combolists Work

Combolists such as "1800_iCloud_KRDCLOUD" are compiled email-and-password pairs, often gathered from earlier breaches or malware infections and named after the type of accounts they target, in this case suggesting Apple iCloud-related logins. These files typically pass through several private Telegram groups before showing up on more public channels, and by the time they are widely shared, the data has often already been tested against multiple websites.
