Why is credential theft a concern for email security?

Credential theft is a significant concern for email security because it can result in unauthorized access to sensitive accounts. When attackers obtain users' credentials, such as usernames and passwords, they can log in to email accounts and use them for malicious purposes. This includes stealing personal information, launching phishing attacks against contacts, and accessing confidential company data.

Unauthorized access can lead to a range of harmful actions, including identity theft, financial fraud, and data breaches that compromise both individual users and organizations. Thus, the security of credentials is paramount in preventing these scenarios and ensuring that email communications remain secure and trustworthy.
