Wonder if ClamAV might have learnt this trick from malware implementations.
- criddell 4y agoI had set up dnsmasq once and spotted all these weird DNS requests coming out of our network. Turns out some Java installation builder software was using DNS to verify the license status of the software. They would do a lookup something like $LICENSE_NUMBER.$NAME.$ZIPCODE.example.com and the reply would indicate the license status.
