• Social engineering to manipulate targets into revealing credentials.
• MFA fatigue or MFA bombing strategies to overwhelm multi-factor authentication protections.
• SMS-based credential phishing to capture login information and sensitive data.
• Historical footprint: the collective has targeted numerous high-profile organizations and sectors, leveraging stolen data to demand ransoms or leverage extortion.
