Stolen Mixed Credentials Enable Account Takeover at Scale

With 3,236 validated account credentials, threat actors can automate attacks across dozens of platforms simultaneously. Each successful login can lead to financial fraud, data theft, or account resale on criminal marketplaces within the same day.
