Description

Other noteworthy stories that might have slipped under the radar: Cloudflare WAF bypass, Canonical Snap Store abused for malware delivery, Curl terminating bug bounty program The post In Other News: €1.2B GDPR Fines, Net-NTLMv1 Rainbow Tables, Rockwell Security Notice appeared first on SecurityWeek .

Impact

European organizations face multifaceted risks from these combined issues. The GDPR fines demonstrate the severe financial and reputational consequences of non-compliance with data protection laws, emphasizing the need for robust privacy controls. The availability of Net-NTLMv1 rainbow tables threatens organizations still supporting legacy authentication protocols, potentially enabling attackers to compromise credentials and escalate privileges, which can lead to data breaches and operational disruption. Industrial sectors using Rockwell Automation products may be vulnerable to targeted attacks affecting critical infrastructure, with potential safety and availability impacts. The Cloudflare WAF bypass exposes web applications to exploitation attempts, increasing the risk of data theft or service disruption. Malware delivery via the Snap Store highlights the risk of supply chain attacks, which can undermine trust in software distribution channels. The end of the Curl bug bounty program may slow vulnerability discovery in a critical internet tool, indirectly increasing exposure. Collectively, these threats could lead to data breaches, operational downtime, regulatory penalties, and erosion of customer trust, particularly in sectors reliant on legacy systems and industrial control technologies.

Defensive guidance

European organizations should immediately audit and disable legacy authentication protocols such as Net-NTLMv1 to prevent credential compromise via rainbow table attacks. Implement multi-factor authentication (MFA) to reduce reliance on password hashes. For industrial environments using Rockwell Automation products, apply all available security patches and monitor vendor advisories closely. Enhance web application security by deploying layered defenses beyond WAFs, including runtime application self-protection (RASP) and regular penetration testing to detect bypass techniques. Strengthen supply chain security by validating software sources, employing code signing verification, and monitoring for unusual behavior in software distribution platforms like the Snap Store. Maintain GDPR compliance through continuous data protection assessments, staff training, and incident response readiness to mitigate regulatory risks. Encourage internal vulnerability discovery programs to compensate for the Curl bug bounty termination, ensuring critical tools remain secure. Finally, increase network segmentation and monitoring to detect lateral movement attempts stemming from compromised credentials.
