This chapter explores further into active botnet families detected in 2018. We concentrate on four distinct families and tools focusing our analysis on their behavior changes, sample version changes, sample variants, and average age of C&C servers, to better understand the dynamic lifecycle of botnet families throughout 2018.

3.5 Delivery and Propagation 3.5.1 Behavior Seen Studying 25 million intrusion logs extracted from NSFOCUS managed services customers in 2018, we found that approximately 14 million logs recorded intrusions using weak password cracking mainly against Telnet, RDP, and SSH services. From other logs, a large portion of intrusions seen were vulnerability-based intrusions, with 54 vulnerabilities […]

3.4 DDoS Attacks 3.4.1 Behavior Seen Effective attack instructions are botnet attack instructions that control a task other that starting and stopping. Effective attack instructions captured in 2018 included DDoS, Local Area Network (LAN) scanning, and vulnerability exploits among other types of attacks. There were 440,000 DDoS attack instructions issued from botnet families, constituting most […]
