Suspected Bot List [2017-08-22]

detection period: 2017-08-22 00:00-23:59 UTC
number of suspected bots' IPs listed here: 25

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.
