TDL4 DNS Request Traffic

L4 Transporter

Hi everybody

I have a Pa-2020 with PanOS 6.0.6. Today my theat log monitor shows message about "TDL4 DNS Request Traffic" and traffic is drop (that is fine) but the problems is to analize the source, the attacker IP its my Internal DNS not the real infected computer, I tried to use the SINKHOLE facility to detect it but it doesn't work.


Do anybody knows how to detect the infected computer?


best regards
