The Rise of Identity-Based Attacks: What You Need to Know

The Shift to Identity

Traditional perimeter security assumed attackers needed to break through firewalls and exploit vulnerabilities. Today's attackers take an easier path: they steal credentials and log in as legitimate users.

Why Identity Attacks Work

Credential Availability - Billions of credentials available from data breaches - Phishing kits are sophisticated and cheap - Dark web marketplaces sell access

MFA Gaps - Many organizations still don't have MFA - Legacy authentication bypasses MFA - MFA fatigue attacks succeed

Detection Difficulty - Legitimate credentials look like legitimate access - Traditional security tools miss the attack - Dwell time before detection averages months

Common Identity Attack Types

1. Credential Stuffing — Automated testing of stolen credentials
2. Password Spraying — Testing common passwords across many accounts
3. Phishing — Tricking users into revealing credentials
4. Token Theft — Stealing session tokens to bypass MFA
5. MFA Fatigue — Bombarding users with MFA prompts until they approve

Defense Strategies

• Implement MFA everywhere (and use phishing-resistant methods)
• Monitor for impossible travel and anomalous sign-ins
• Deploy dark web monitoring for credential exposure
• Use Conditional Access policies to block risky sign-ins
