Finding 1: In 2019, over 30 types of IoT vulnerability exploits were captured, most of which targeted remote command execution vulnerabilities. Though hundreds of to thousands of IoT vulnerabilities are unveiled each year, only a few can exert an extensive impact. Attackers were keen on targeting devices (routers and video surveillance devices) exposed in large […]
According to ZDNet’s reports, FBI released a warning last week that some new network protocols were used by criminals to launch large-scale DDoS attacks. Three protocols and one Web applications were found as DDoS attack vectors, including CoAP, WS-DD, ARMS and Web-based Jenkins.

Android, as a widely used mobile operating system, is vulnerable to an increasing large number of malware families owing to its openness and privilege issues. Such malware can even be spread via legal channels, including Google Store.
In the reconnaissance phase, a bad actor can determine which targets to attack through batch scanning. Such scanning is often focused on user names and passwords for access to and vulnerabilities in devices. Besides, an attacker may try to compromise targets by delivering malicious baits to their email addresses collected previously.

Cryptojacking Malware In 2019, the pickup in cryptocurrency prices led to an increase in the number of cryptojacking malware families. Of all these families, Monero mining trojans still took a dominant place. EternalBlue and weak password cracking were the major methods for ransomware families to compromise large enterprises in financial and telecom sectors and spread […]
Executive Summary In recent years, more and more protocols that may cause UDP reflection attacks have come into our sight, such as CoAP[1], Ubiquiti[2], WS-Discovery[3], OpenVPN[4], and a certain DVR protocol[5]. These attack patterns are different from DNS, SSDP, NTP, Memcached, and other reflection attacks that are well familiar to us, posing certain challenges to […]
Botnets can pose a variety of cyber threats. NSFOCUS Security Labs has been focused on the capture, track, and study of botnet-related threats. In 2019, the Labs further upgraded its capturing and tracking techniques and capabilities and expanded its scope of interest to cover more diverse threats, including cryptojacking, ransomware attacks, data theft by banking […]
