Inside the RaccoonCloud Logs: How Malware Harvested 15,633 Passwords

HEROIC analysts found a stealer log named "RaccoonCloud" uploaded to a Telegram channel on December 17, 2022. The file exposed 15,633 records tied to U.S. users, including email addresses, plaintext passwords, and the API host URLs those credentials unlock.

Why This Stealer Log Is Dangerous

Every password in this log was stored in plaintext, so there is no encryption to break before the credentials can be used. Each password is also matched to the exact web address it belongs to, which means an attacker does not need to guess where to try a stolen login. They can go straight to the account.

What Was Exposed in the RaccoonCloud Log

• Email addresses
• Plaintext passwords
• API host URLs tied to each login

Why This Matters

A log of 15,633 working email and password pairs is a ready-made toolkit for credential stuffing, where attackers test the same login across many sites hoping people reused passwords. Anyone caught up in this leak faces a real risk of account takeover on any service where they used the same password, along with the identity theft and fraud that often follows.

Inside a Stealer Log: How Malware Harvested These Passwords

A name like "RaccoonCloud" points to infostealer malware, a category of malicious software that infects a device and quietly copies saved browser passwords, autofill data, and active login sessions. The malware bundles everything it finds into a log file, which is then shared or sold in Telegram channels like the one where HEROIC found this file on December 17, 2022. This is a common and low-effort way for attackers to obtain large volumes of working credentials without ever targeting a specific company.
