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 frequently exploited (Shown in the table) mostly against routers and IoT cameras.
