Malicious?

Paolo Lat over 6 years ago

Hi There,

Just saw this on our Web Protection > Top Users By Traffic

Any idea why is it showing a long string of lines or possibly a domain instead of an IP?

Is this a compromised machine?

Is this a something that they're trying to access?

Is this the user being on a VPN?

This seems just normal resolved domains. It looks like the other IPs are just internal IPs and there is no reverse lookup configured.

Maybe tell us a little more regarding your infrastructure.

I'm thinking that if this are just resolved domains then that would mean we would have an internal domain like this right? but we don't

Well, they do resolve to external IPs, so I would check your network and UTM configuration for holes. Somehow those hosts are using your web proxy, it appears.
