The most common identity-based cyberattacks include password spray attacks, phishing, and breach replay attacks. Password spray involves guessing common passwords across multiple accounts, while phishing tricks users into providing their credentials on fake websites or through deceptive communications. Breach replay takes advantage of reused passwords from compromised sites to access other accounts. These attacks are executed on a large scale and highlight the importance of implementing strong identity security measures.

Multifactor authentication (MFA) is a crucial defense against identity attacks, as it significantly reduces the risk of account compromise. Despite its importance, only 28% of users had any MFA session last month, indicating a low adoption rate. Microsoft deflects over 1,000 password attacks per second, and the majority of compromised accounts lack MFA. Organizations are encouraged to require MFA for all users to enhance security and protect against prevalent attacks.

Organizations can enhance their identity security by implementing several strategies: first, they should require multifactor authentication for all users, utilizing tools like Microsoft Authenticator or FIDO. Second, applying Conditional Access rules can help defend against application attacks. Third, using mobile device management and endpoint protection policies can prevent token theft. Lastly, reducing reliance on on-premises infrastructure and integrating security operations with identity management can strengthen defenses against sophisticated threats.
