My router got hacked. And people suggest that the best way is to factory reset the router, then reset all the devices using the network.

I'm getting a new router so the reset router part is solved.

My further question is, there are 9 devices in my house: 2 desktops, 2 laptops, 1 iphone, 1 ipad, 1 android phone, 2 android tablets. Do I need to reset all of those devices? Would there be a problem if I leave one or two of the devices not reset? Would the hacker get into my network again through the one device that's not reset?

One of the desktop is my son's. And it's all him homework and games. No important login info there. Can I leave this one not reset? And another laptop my mom just use for browsing and simple stuff. Can I leave this one not reset as well?

Is it not necessary to reset the iphone and ipad? One of the android tablet has got seem like Adware on it, ads popping up all the time. How can I reset this tablet?

    "My router got hacked." - what happened, exactly? – TessellatingHeckler May 27 '17 at 1:31
  • I got scammed and hacked. The scammers said they were from Microsoft and my computer had virus and they were going to install some antivirus software on my computer and clean the virus for me. So I let them remotely connected to my computer for more than an hour! God knows what they’ve been doing in that time! – kekehuang11 May 27 '17 at 2:23

    Then it's your pc that got hacked not your router. – t.m.adam May 27 '17 at 2:49
  • At first I thought so too. But then I used another computer in my house to change my Microsoft account password. After that I found out that they logged into my account. That's when I thought probably they hacked the router so all the devices in my house are under threat because they are all using the same router. – kekehuang11 May 27 '17 at 4:57
  • Dod you provide them password to your router? Do you have passwords stored on your PC in clear form? If so I would recommend to reinstall all devices affected and also, change all passwords affected. – Fis May 27 '17 at 4:57

Facts

A Malicious guy accessed your home network for more than an hour, you didn't know exactly what happened there, but for some reasons, you assumed that the router has been compromised.

Answer

Nuke it from orbit.

Wipe all your devices. Within one hour, a malicious person can do some tremendous damages.

As they are not that expert (needed your access to infect you) you are probably safe on iphone and ipad but they may access your data and passwords using saved passwords on your system.

As in my experience you'd better to backup everything first.

  • You can backup your passwords using password managers like Lastpass.
  • Also install some smart security antivirus like ESET or Kaspersky.
  • Reset your router firmware and reconfig it NO DEFAULT PASSWORD.
  • Look how you let them connect to you remotely, remove that software and etc.
  • Reset all of your passwords cause they may use them against you. Lastpass makes it much easier [with auto password changing for popular websites].

Its better to do all these things offline cause they may see your changing thins ans they try to be more creative.

Restoring windows is an good idea too, It will not cause that much data lose and its kind of a great idea after backup and before other things.

And the last thing to do is to submit a crime report (Don't let others to fall the same hole as you did).

    Not sure why you are downvoted, they are indeed probably just people following a checklist in what to do, so nothing out of the box hard. – Dr_Bunsen Sep 25 '17 at 9:29

To add to Mahdi's great advice, also be sure you run "updates" on ALL of your devices - including the firmware on your router(s). The latest Wanna Cry ransomware was successful because much of the world fails to update their computers. Do that, and what Mahdi said, and install an antivirus (AND SCAN EACH PC WITH IT) and you'll be in good shape. AVG is free and has a great product.
