Hotmail 2FA CHEETAH Leak Means Someone Could Log Into Your Accounts

HEROIC analysts tracked the Hotmail 2FA by CHEETAH dataset shared on Telegram in March 2025. The breach exposed 1,936 records of Hotmail accounts with two-factor authentication data, including email addresses, plaintext passwords, and URLs from compromised devices.

Hotmail Accounts With 2FA Data Are Especially Valuable to Attackers

When a stealer log captures Hotmail credentials alongside 2FA information, attackers gain the ability to bypass one of the most important account security layers. These credentials are significantly more valuable than standard username and password pairs because they enable account access even on protected accounts.

• URLs (endpoint context)

How 2FA-Bypassing Credentials Enable Full Account Takeover

Standard credential stuffing fails on accounts protected by two-factor authentication. When stealer malware captures session tokens and 2FA data alongside passwords, it negates this protection entirely. Attackers who purchase this data can access accounts that victims believed were secured.

How Stealer Log Breaches Work

Stealer logs are produced by malware silently installed on victims' computers. The malware captures usernames, passwords, and browser session data before sending it to criminals, who then package and sell the data on Telegram channels and dark web markets.
