In Q4 of 2024, NSFOCUS observed and successfully mitigated the largest DDoS attack ever recorded under the cloud-based DDoS Protection Service (DPS). This massive DDoS attack targeted a telecommunications service provider, one of NSFOCUS’s global clients. The telecommunications industry frequently faces such cyber threats. However, the scale of this attack was unprecedented, with peak traffic […]

The video above demonstrates an automated penetration test in a simple container escape scenario. In this video, in addition to using NSFOCUS’s open-source cloud-native cyber range software Metarget (for quickly and automatically building vulnerable cloud-native target machine environments), NSFOCUS’s own developed cloud-native attack suite Coogo is also utilized. Today, we will provide a brief introduction […]

When researching vulnerabilities, we often find that environment setup takes up a significant amount of time, and in comparison, the actual time spent testing PoCs and exploits may be relatively short. Meanwhile, there are excellent security projects in the open-source community, such as Vulhub and VulApps, which package vulnerability scenarios into images, allowing researchers to […]

Overview Recently, NSFOCUS CERT detected that Zabbix released a security announcement and fixed the SQL injection vulnerability (CVE-2024-42327) of Zabbix server. Due to the SQLi vulnerability in the CUser class in the addRelatedObjects function, attackers with default user permission or API access can call the CUser.get function. This could lead to unauthorized access to sensitive […]
