WATERCLOUD_NOTIFY-04.08.2024-148 FILES-THANKS FOR SUB: 2,359 Leaked

Email and password, paired together and ready to use: that's what HEROIC analysts found in a stealer log labeled WATERCLOUD_NOTIFY-04.08.2024-148 FILES-THANKS FOR SUB, posted to Telegram and dated August 4, 2024. The file contains 2,359 records combining email addresses, plaintext passwords, and the URLs they unlock. The only way to know if your pairing is among them is to scan your email.

Why a Ready-Made Login Pair Is So Risky

Because the email and password in this file are already matched to each other, an attacker does not need to guess which password belongs to which account. The passwords are stored in plain text, so there is no encryption standing between the file and a working login. Anyone who reused that same password on another site hands an attacker a second, or third, way in.

What the 148 File Stealer Log Holds

• Email Addresses: identifies the real inbox tied to each stolen login pair.
• Plaintext Password: readable as is, so an attacker can log in without cracking anything.
• URLs: marks exactly which site or app each pairing was captured from.

The Fallout From a Leaked Login Pairing

Once a pair from this file is confirmed to work, it can be used to take over the account directly, lock out the real owner, and mine the account for further personal details. If the same pairing was reused on an email provider, it can also be used to reset passwords on other services tied to that address. Reused banking or payment logins carry an added risk of direct financial loss.

How Device Malware Builds These Pairings

Stealer malware sitting on an infected device quietly copies saved logins straight out of the browser, pairing each email with its stored password automatically. Whoever controls the malware then packages these pairings into a file like this one and shares it on Telegram. Nothing about the destination websites was broken into, the device itself was the point of failure.

Is Your Login Pairing in the 148 Files Leak?

Scan your email to check whether your pairing turns up in this file. If it does, reset or clean the device that was likely infected first, then change the password from a different, trusted device afterward. Treat a work email pairing with the same urgency as a personal one.
