Suspicious WiFi connection detected

The Sophos app on my android phone gave me a security warning saying that:

Suspicious WiFi connection detected

We’ve detected suspicious behaviour on your WiFi Connection. This might be caused by a public network requiring authentication. In this case, open your browser to sign in.

I have reset my home Wifi password but I still keep getting the same message. Can someone advise what I should do?

  • Hi Jane S,

    Thank you for collecting and sharing the logs.

    The Intercept X Mobile app performs a number of checks when you run the Wi-Fi security check. The results from the logs you provided show:

    isOnline: true
    isConnectedToWifi: true
    isConnectedToMobile: false
    isRedirection: false
    isPinningError: true
    isCaptivePortal: false
    isCaptivePortalSafe: false
    wrongDnsLookup: false
    isSslStripping: false
    isArpSpoofed: false
    isNotRedirectingToHttps: false
    dnsRedirect: false
    isUnsecureContentInSecureSite: false

    During this check the certificates stored in the Intercept X Mobile application are checked against a few websites. If these checks fail, this error may come up. In a home-network however, this is not unexpected. If you wish to investigate further, I recommend checking if your network router/modem has any security features that are affecting the results you're seeing.

    You can also try testing with another device to verify if the issue is with the router, or with your mobile device specifically. In general, for a home network, this error does not always mean that you are compromised.

  • Hi Gladys,

    Thank you. I have tested with another device and the issue didn't occur. It only seems to occur with my device. Does that mean that my device has been compromised?


  • In some cases, uninstalling and reinstalling the Intercept X Mobile application will also resolve the issue. Let me know if this works for you.
