      @johnpoz There should be a thumbs down button and after enough of them, that person is flagged as unhelpful, sarcastic, demeaning or similar.

        Yup maybe the Russian's are hiding in your machine - I mean that has to be the only logical answer.. <rolleyes>

        BTW - omg, the Russians must be hacking me as well.. There is a duplicate mac on my network with a 169.254 address..

        arp.jpg

        Oh shit - there is another duplicate

        arp1.jpg

        Oh my god, must be the china hackers and the germans, maybe candada is in on it too..

        arp2.jpg

        Maybe I should contact some CISSP college professors to explain it too me...

        Or just maybe - its not RU hackers, and its how networking works when you have a device that likes to use APIPA (the link local 169.254 address space) as well as its normal IP.. No couldn't be that must be hackers doing MITM on my camera..

          @smoses said in New user Compromised pc - APT & keylogger:

          LinkedIn CISSP professionals college professors teach duplicate mac's are MITM's. Go argue with them. I've verified it with them and other CISSP professionals including a RAT. Maybe the better question is what is proof to you johnpoz? Are you saying the CISSP's are wrong?

          ????

          That "MITM" must be on your LAN, if you see any MAC other than the nearest router. MAC addresses are valid on the local LAN only and discarded when a packet passes through a router and a new MAC from the next interface is used.

            @johnpoz they have an Arp watch package now?? This could tie into the experimental layer 2 Ethernet filtering rules. Cool!!

              @JonathanLee they have had arpwatch for quite sometime - not all that happy with it, it can cause a lot of noise with notifications.. have not been able to figure out a way to not have it put into the db 0.0.0.0..

              But I will run it now and then for testing/play..

                @johnpoz I wonder if that database can be used to help populate the experimental Ethernet filtering rules some way. That is a pain to enter by hand.

                  @smoses have you attempted to replace your AP your using? It might have an invasive container running on top of it. That is a big security issue right now. Unknown containers that can data marshal your NIC. Have you ever attempted to fingerprint the operating systems running with p0f?

                  But if you have someone using all your information that sounds like identity theft.

                  https://forum.netgate.com/topic/180467/23-05-source-os-p0f-fp-database-signatures-outdated/

                  Again the signatures are outdated but you can add approved ones manually and comparmentalize them with the fingerprints. It's really cool.

                  I really wish they would update the fingerprint database upstream for openBSD and even add AP's OS fingerprints that contain internal NAS systems. Flat out fix container issues once and for all. For example, Apple Airport Extreme APs have a Linux OS on them that helps run the NAS (time machine). This Time Machine product was an older Apple product with huge TB sized drives inside an AP. Again, an older version of SMB server message block was what was used to helped make this massive home all in one NAS (network attached storage) function. You could even access the NAS filesystem remotely off LAN with this type of AP. This was eventually recommended to be disabled because of a security concern within SMB ( disable the remote access). The issues were similar to the Eternalblue smb exploit, as the AP contained the same SMB issues. So yeah, I am thinking if your really having all of these issues and feel this unsafe, try to replace your AP. Give that a shot.

                  I had a bug once everyones recommendations at Microsoft support were just reinstall. Again, if I did that the meat/heart of the problem would never have been resolved ever. They eventually patched it for everyone.

                  Proof is needed. I recommend Wireshark, Wireshark, Wireshark logs. Hard evidence is what is needed. You can also run Airsnort and check traffic on the wifi side too. Do you have the Norton alert screen shot?

                  I hope your ok. If you are overwhelmed you can always ask for help. I hope this community makes you feel safer. It's ok, we will get the bad guys. You're in good hands.

                        @provels but hey it's got a cool puzzle inside it to fix still. If it's thrown out it will just pop up somewhere else and have a new victim.

                        https://www.rosevilletoday.com/news/foreign-hackers-target-home-and-office-routers/

                        A home office router bug has occured in the past in some locations. Leading to the default solution when say the government does start to discover the main threat or issue, is that everything is always timed just right with a math equation so that all the sudden it's "upgrade time" and bingo now it's time to a new system. Like say a fiber optic network. Or, to use that and say we disconnected that old equipment force the upgrades. Leading to that issue occurs again inside all new equipment that again is made in another country with different data sovernity and laws again. After, that has been resolved with what I have coined as "the consumer replacement upgrade mitigation platform" it becomes a throw the bug under the bus replacement plan again with statements like, "that issue was the old equipment, so its time to update!!" This results in tons of e-waste and tons of excuses for who's to blame. A couple months later it's back to the hacked devices as usual and the government it's back to catch up and new training as usual. Or the other solution now is they just silo the guys that find the bugs with a shiney new all in one equipment plan and tell them they can't use their own routers. That way it's harder to catch those invasive actors. Hey, we are all to blame we want that latest greatest product. What this needs programing professionals that can stomp out issues with compliance servers firewalls and code we can trust built with communities. Open source is a good solution, it's starting to get closer to were we are one step ahead of the invasive actors.
