      Exclamation Wireless security question

      I think there might have been an intruder on my sister's home wireless network and I'd really appreciate it if you could help me out with a few things. Firstly, is it possible they might have installed a rootkit or packet sniffer on the router (it's a Netgear DG834GT), and would resetting the router definitely erase all that? Secondly, if I was to install Wireshark on her laptop to monitor the network traffic, would it be able to capture everything or can a rootkit bypass Wireshark? I need to sort this out fairly urgently so I'd really appreciate any advice.

      you can log in to the router and check what devices are/have been attached to the router. the WPA-PSK security on your router is encrypted, if somebody has access to your wireless network it is far more likely they have either been given/seen your network key in which case you can change that on your router settings page as well

      It is very unlikely anything has been installed on the router without her knowledge. It is more likely something has been installed on her PC. To check this you can run a couple of anti-malware programs such as -
      SUPERAntiSpyware.com | Remove Malware | Remove Spyware - AntiMalware, AntiSpyware, AntiAdware!
      and

      Malwarebytes Anti-Malware - Free software downloads and software reviews - CNET Download.com.


      To boost the security change the WPA key in the Wireless settings in the router. This can consist of 8 to 63 characters, so it can be really strong.
      Also add the PC/Laptop to the Wireless Access list, also in the Wireless settings. This is not foolproof but can keep out the average 'war driver'.
      In the Router settings, click the Remote Management link and untick 'Turn Remote Management on'. Finally in the WAN setup link, untick any boxes that may be ticked.
