The breach at Okta highlights the importance of vigilance in security measures and the potential risks associated with seemingly reasonable requests, such as uploading HAR files to a support system. The incident demonstrates how hackers can exploit vulnerabilities in support teams, using them as entry points to gain control over the main dashboard and entire support system. The delayed response from Okta has been criticized, particularly its lack of transparency and acknowledgment of customer notifications. The breach also underscores the need for customers and security teams to stay vigilant and implement multiple layers of controls, enforced processes, and defense-in-depth policies to prevent breaches.
