I. Background In August, NSFOCUS Global Threat Hunting System spotted an abnormal trend of DDoS attacks against Libya. NSFOCUS Security Labs sorted out the traffic changes of DDoS attacks in August and found that this attack may be related to the turmoil in Libya in August by comparing it with key events in Libya in […]
Recently, NSFOCUS SOC team summarized the findings from attack and defense drills in the first half of 2023. In these smokeless battles, the attackers advanced with aggressive strategies, while the defenders relied on comprehensive defense systems, taking measures from protecting, monitoring to tracing, and resisting every attempt to breach their defenses. Vulnerability and Asset Impact […]

Affected users should take protective measures as soon as possible. The details of the vulnerability are as follows: Apple ImageIO Remote Code Execution Vulnerability (CVS 2023-41064): […]
Overview Recently, NSFOCUS CERT has monitored that Google Chrome has officially released security announcements and fixed several security vulnerabilities. The key vulnerabilities are as follows: Google Chrome Cross Border Read Vulnerability (CVE-2023-4761): Due to an out of bounds memory read vulnerability in Google Chrome FebCM, attackers who can disrupt the renderer process can perform out […]
Overview Recently, NSFOCUS CERT detected an Authentication Bypass vulnerability in VMware Aria Operations for Networks. Due to the lack of unique cryptographic key generation, Aria Operations for Networks is susceptible to an authentication bypass vulnerability. Attackers with network access to Aria Operations for Networks could bypass SSH authentication to gain access to the Aria Operations […]
We proudly announce that NSFOCUS was again included in Gartner® Hype CycleTM for Smart City and Sustainability in China (2023) report1 in CPS Security. “Cyber-physical systems (CPS) are engineered systems that orchestrate sensing, computation, control, networking and analytics to interact with the physical world (including humans). When secure, they enable safe, real-time, reliable, resilient and […]
