Suspected Bot List [2018-02-16]

detection period: 2018-02-16 00:00-23:59 UTC
number of suspected bots' IPs listed here: 1

IP addresses listed here all exhibit strange network behavior. As I could not notify the victims for various reasons (no working abuse contact, mailbox over quota, etc.), I list them here instead. I have to emphasize that those are just *suspected* to be malware-infected computers.
