Executive Summary

Cybersecurity threats continue to escalate with critical vulnerabilities being exposed in various platforms. The increasing reliance on AI is also making it easier for attackers to launch sophisticated campaigns. Meanwhile, the FBI reports a record-breaking $21 billion lost to cyber-enabled crimes last year.

The trend of using AI-driven attacks is becoming more prevalent, and organizations must be prepared to address these emerging threats. Critical vulnerabilities in Windmill developer platform and Nextcloud Flow have been exposed, allowing remote attackers to take full control of affected systems.
