Token theft is a growing threat in the cybersecurity landscape, particularly as more organisations adopt multifactor authentication (MFA) and other security measures. Attackers are increasingly targeting tokens to bypass these defences and gain unauthorised access to sensitive data.

Understanding and mitigating token theft is crucial for maintaining the integrity and security of your customers' environments. By staying informed about the latest threats and implementing robust defence mechanisms, partners can significantly reduce the risk of data breaches and enhance their overall security posture.

We recommend our partners to take the following actions to protect against token theft:

Educate and Train Staff
Ensure that your teams understand the mechanics of token theft and the importance of securing tokens. Provide training on recognizing phishing attempts and other common attack vectors.

Implement Token Protection Measures
Use Microsoft Entra's token protection features to bind tokens to specific devices, preventing their use on unauthorised devices. Configure Conditional Access policies to enforce token protection and minimize the risk of token misuse.

Adopt a Defence-in-Depth Strategy
Employ a multi-layered security approach that includes device compliance policies, Credential Guard for Windows users, and Continuous Access Evaluation to detect and respond to suspicious activities in real-time.

Leverage Monitoring Tools
Utilize Entra ID Protection and Microsoft Defender to monitor for signs of token theft and investigate potential incidents using Microsoft Sentinel or other Security Information and Event Management (SIEM) tools.
