In this massive attack, threat actors compromised more than 42,000 devices via a critical privilege escalation vulnerability discovered on October 16 with a severity rating of 10.0.
That's why security analysts marked this attack as one of the most significant edge attacks.
Even Okta's CISO revealed the threat actor accessed and downloaded a report with user names and emails but no sensitive data.
