Cybersecurity never takes a break, and neither do hackers. As last week concluded, fresh attacks were already in motion, showcasing the ongoing challenges in the digital landscape.
This week’s summary highlights critical updates that organizations need to consider for bolstering their defenses. From software vulnerabilities to massive DDoS attacks and innovative ransomware methods, here are the key developments everyone should be aware of:
Threat of the Week
Cisco Zero-Day Vulnerabilities Under Attack
Cybersecurity agencies have issued warnings about two critical vulnerabilities in Cisco firewalls being actively exploited in zero-day attacks. These flaws allow attackers to deploy sophisticated malware, such as RayInitiator and LINE VIPER, which have evolved significantly in their capacity to evade detection. By exploiting CVE-2025-20362 and CVE-2025-20333, adversaries can bypass authentication and execute malicious code on vulnerable systems. This activity appears to be linked to a suspected Chinese hacking group identified as UAT4356 (also known as Storm-1849).
