Analysis of IoT Attack Sources From NSFOCUS’s IoT threat intelligence, we can associate DDoS attack events with IoT devices. Further analysis of IoT devices compared to source IP addresses of DDoS attacks found that 3.14% of DDoS attackers are IoT devices. Though this proportion is relatively small, the number of DDoS source IP addresses is […]
2.2.2 Dragonfly 2.0 Malware The Dragonfly organization, also known as Energetic Bear, mainly carries out cyber espionage activities targeting electric power operators, major power generation enterprises, petroleum pipeline operators, and industrial equipment providers in the energy sector. According to a Joint Analysis Report (JAR) released by the Department of Homeland Security (DHS), Dragonfly is a […]
Top 10 countries in attack counts: The above diagram shows the top 10 regions with the most malicious IP addresses from the NSFOCUS IP Reputation databases at January 19, 2020.
2.2 ICS-Targeting Malware Analysis In recent years, more and more malware took ICSs as targets, causing an increasingly great damage. The following sections analyze major ICS-targeting malware.
Overview Multiple vulnerabilities in the authentication mechanism of Cisco Data Center Network Manager (dcnm) (cve-2019-15975, cve-2019-15976, cve-2019-15977) may allow unauthorized remote attackers to bypass authentication and perform arbitrary operations with administrative privileges on the affected devices.
Typical ICS Security Incidents As ICSs are increasingly informatized and open, more and more attacks are hitting ICSs, doing an increasing harm. ICS-targeted attacks use the IT network as a springboard to affect the operating of OT systems. Currently, attacks against ICSs are carried out to achieve three purposes: disrupting the normal operating of ICSs, […]
Technical Trend of ICS Information Security 1.3.1 General Introduction As the application of IT technologies in industrial fields is expanding in breadth and depth, ICSs are facing an increasing number of security risks. ICSs’ original security protection systems which feature border separation and protection tend to be associated and integrated with business. With the emergence […]
Development of ICS Information Security Since the Stuxnet virus explosion, countries all over the world have taken ICS security issues to a new height by actively working out and introducing related policies, standards, technologies, and solutions. A look into ICS security developments around the world reveals that the USA is the first to research and […]
Distribution of IoT-based Family Samples We analyzed IoT-based malicious family samples captured by NSFOCUS threat hunting systems (see Figure 7-1), those captured by NSFOCUS Threat Intelligence (NTI) and those captured by VirusTotal (see Figure 7-2). The two figures, though presenting different data sources, both indicate that Gafgyt and Mirai take the first two places on […]
