    Just tried going to ARP Table but it's not loading.. after a couple minutes it started loading:

    WAN 192.168.1.101 00:26:*** Permanent ethernet

    It basically has the same stats as the 192.168.1.1 except it says Permanent

    SMH... there are a bunch of MAC addresses/192.168.1.x addresses but I only connected 1 computer to pfSense's LAN

      Do you have another router conneced between the Internet and your pfSense WAN interface.

        @NogBadTheBad Yes, I do. Internet -> Router -> Router's LAN -> pfSense -> Single Computer

          Well its a device connected to that other router then, either by ethernet or WiFi.

            Yeah, I figured that... I'm just curious how it knew to start scanning and then dropped silent all of a sudden

              Here are the logs (Note: I had to remove a massive sum of the malicious logs because Stack does not allow that many characters... I left in the parts that show the Network Trojan and Scanning of the pfSense Router (IP address: 192.168.1.101):

              Can you switch the upstream router to modem mode ?

              If you can it would be better as you'll have a non rfc1918 IP address on the pfSense WAN interface and you won't have a double NAT occurring.

                You have an active malware infection. It's certainly capable of knowing what network its on, changing its own IP address, and then "hiding" itself to fall silent until called upon by its master.

                  @NogBadTheBad @msf2000 This post is the truth and partially for my own protection:

                  ok, do you think I should reinstall pfSense? Or if they can hack my router I'm supposed to let them have their way with my set up? I experienced some extremely high level hacks in the past so I'm not sure what I should do (you would not believe --- I tracerouted at one point and saw my traffic going through countries on the other side of the world... also I logged into my cell phones manufacturer menu and saw someone changed the Cellular SSID to the name of one of my research projects -- Radiation TDR.. then sh*t got gnostic)... on one hand, I (POSSIBLY still) have this unknown group that's capable of doing extremely high level hacks on my system (I believe they actually fixed up some settings last time they hacked me) and on the other hand I live with a bunch of computer n00bs who prolly click virus.exe like its candy..

                  I'm not sure I want to even "protect" myself from the high level group -- I wouldn't want to cause some guy in the NSA to be like, "Shit, they know our IP block now" But on the other hand, I want to keep the script kiddies out.

                  Any recommendations on what to do? Is this malware capable of infecting the rest of the LAN? There is some sensitive information on the network PLUS BTW IN CASE I POSTED IPs... HIGHLY DO NOT RECOMMEND HACKING THIS NETWORK --- just read this post which doesn't even scratch the surface

                    @ProfessorManhattan

                    It just looks like DNS queries on weird ports... Mostly reconnaisance-type connections. I would just the host/client device. I don't see any evidence that your pfSense box is hacked...

                    Also, connections all over the world are not necessarily a sign of compromise... something as simple as getting the current time (NTP) from a Russian timeserver can be benign and even routine.

                    In any event, we're off topic. Suricata helps you detect malware/reconnaisance, and it's doing its job as far as I can see.

                      No it's not a pfSense issue.

                      It's an issue with the hosts.

                      By default pfSense blocks anything hitting the WAN interface.

                        @NogBadTheBad Thank you for the re-assurance. I can take off my tin foil hat as you say and not waste a month compulsively re-installing pfSense which probably would be from a source with a mismatching checksum anyway.
