So my understanding is shodan is a crawler that scans IP networks to try to find badness.
From their webpage malware[dot]hunter[dot]io:
"Why did my security software raise an alert?
Malware Hunter doesn't perform any attacks and the requests it sends don't contain any malicious content. The reason your security product raised an alert is because it is using a signature that should only be used for traffic leaving the network (egress) but is incorrectly being applied to incoming traffic (ingress). In other words: the security product is using a signature that was meant to detect when a computer on your network was infected and reporting back to a C2. However, the signature is also being applied to all traffic going into your network which is why it's raising a false alert."
