Dieses Netzwerk wurde kompromittiert

[magnus_mh]

Hallo zusammen,

ich bin neu bei Norton und brauche etwas Hilfe. Bisher habe ich mich immer auf den Windows Defender verlassen. Nach einem Cyberangriff auf unsere Firma möchte ich aber auch mein Heimnetzwerk besser schützen.

Ich habe mich für Norton entschieden, weil ich noch einen ungenutzten Lizenzschlüssel aus einem M365-Bundle hatte.

Jetzt habe ich aber ein Problem auf einem meiner PCs: Gelegentlich erhalte ich die Meldung “Dieses Netzwerk wurde kompromittiert”. Außerdem behauptet Norton, der PC wäre mit einem neuen Netzwerk verbunden und prüft dieses. Der Rechner ist aber immer über LAN mit derselben FritzBox 7590 verbunden. Bei meinen anderen Geräten (Laptops, Smartphones), die alle per WLAN verbunden sind, tritt dieses Problem nicht auf.

Ich frage mich, ob es wirklich ein Problem gibt. Zum Zeitpunkt des Angriffs in unserer Firma war ich auch per VPN verbunden. Alle Scans, auch mit anderen Tools, finden keine Bedrohungen auf all meinen Geräten.

Ich hatte noch ein zweites Problem mit zwei Warnungen nach jedem Neustart: “Schutz gegen Remote-Zugriff deaktiviert” und “Angriffssignaturen deaktiviert”. Diese konnte ich aber nach einer Neuinstallation mit dem Norton-Tool beheben.

Hat jemand eine Idee, warum Norton die “Netzwerk kompromittiert”-Meldung anzeigt, obwohl keine Bedrohungen gefunden wurden? Wie sollte ich mich verhalten, wenn ich diese Meldung sehe?

Danke für eure Hilfe!

Hi everyone,

I’m new to Norton and could use some help. I’ve always relied on Windows Defender, but after a cyber attack on my company, I wanted to improve the security of my home network as well.

I chose Norton because I had an unused license key from an M365 bundle.

Now I have a problem on one of my PCs: I occasionally get a message saying “This network has been compromised”. Norton also claims the PC has connected to a new network and proceeds to check it. However, the computer is always connected via LAN to the same FritzBox 7590. My other devices (laptops, smartphones), which are all connected via Wi-Fi, don’t show this problem.

I’m wondering if this is a real issue. At the time of the incident at work, I was also connected via VPN. All scans, including those with other tools, have found no threats on any of my devices.

I also had a second issue with two warnings appearing after every restart: “Remote access protection disabled” and “Attack signatures disabled”. I was able to fix these by reinstalling the software with the Norton tool.

Does anyone have an idea why Norton shows the “network compromised” message even though no threats have been found? How should I behave when I see this message?

Thanks for your help!

AI Overview
When Norton displays a “network compromised” message but doesn’t find any threats, it can be confusing. Here’s a breakdown of why this might happen and what you can do:

1. Potential reasons

• False positive: Norton’s Wi-Fi Security feature might detect suspicious activity that, upon deeper investigation, isn’t a genuine threat.
• Outdated software: Bugs in the Norton Mobile Security app have previously caused false network compromise alerts, according to a Norton Community post from March 2018. Updating the Norton app might resolve this.
• Network vulnerability: Even if no active threats are found, Norton might be highlighting a potential vulnerability in your network’s configuration, such as easily guessable router passwords or insecure settings, that could be exploited.
• Third-party interference: In some cases, using other security software alongside Norton, or even having certain browser extensions, can interfere with Norton’s network monitoring and trigger false alarms.

2. Troubleshooting steps

• Update Everything: Ensure your device’s operating system, router firmware, and Norton Security app are all up to date.
• Restart Network Devices: Rebooting your router and device can often resolve temporary network hiccups causing false positives.
• Check Router Security: Log into your router’s settings (usually by typing its IP address into a web browser), change default passwords, and verify Wi-Fi encryption is strong (WPA2 or WPA3 are preferable).
• Scan for Malware: Run a comprehensive scan with Norton and consider using additional malware scanning tools to be thorough, according to Reddit user YouveBeanReported.
• Disable & Re-enable Wi-Fi: On mobile devices, toggle Wi-Fi off and on to reset the connection, according to JustAnswer.
• Review Wi-Fi Security in Norton: Access the Wi-Fi Security feature within the Norton app to view details about the network and any identified risks, as mentioned by Norton Support.
• Trust the Network (If Safe): If you are certain your network is secure and the alert is erroneous, you can choose to “Trust This Network” within Norton’s settings.
• Contact Norton Support: If the issue persists, contact Norton Support directly for further investigation and personalized assistance.

In essence, while the “network compromised” alert without detected threats can be unsettling, it’s often a false alarm or an indication of a potential vulnerability rather than an active attack.

AI Overview
Norton may indicate your network is compromised due to suspicious IP traffic, malicious DNS settings, or the presence of unauthorized devices. It could also be triggered by a false positive from Norton’s scan of your network.

Here’s a more detailed breakdown:

Possible reasons for the alert:

• Suspicious IP traffic:

Norton might detect unusual or potentially harmful network activity originating from your IP address.

• Malicious DNS settings:

Your router’s DNS settings might have been tampered with, directing your traffic to malicious websites.

• Unauthorized devices:

Someone might have gained access to your Wi-Fi network and is using it without your knowledge.

• False positives:

Norton, like any security software, can sometimes flag legitimate activity as suspicious, especially on networks with unusual configurations.

• Weak Wi-Fi security:

Using a weak password or an outdated encryption protocol (like WEP) makes your network more vulnerable.

Troubleshooting steps:

1. Update Norton and your router: Ensure both your Norton app and your router’s firmware are up to date to address potential vulnerabilities.
2. Check for unauthorized devices: Review your router’s connected devices list to identify any unfamiliar devices.
3. Change your passwords: Update your router’s admin password and your Wi-Fi network password.
4. Strengthen your Wi-Fi security: Enable WPA2 or WPA3 encryption and disable WPS if it’s enabled.
5. Power cycle your modem and router: Sometimes, simply restarting your modem and router can resolve temporary network issues.
6. Contact Norton support: If the issue persists, contact Norton support for further assistance.

Important considerations:

• VPN usage:

If you’re using a VPN and encounter a “compromised network” alert, it could be due to the VPN server being blocked by your network or firewall settings.

• False positives:

If you’re certain your network is secure, you can try adjusting the trust level of the network within Norton’s settings.

@magnus_mh On your ethernet connected computer disable WiFi scanning within Norton settings. Reboot the device and see if the issue continues. I have this disabled on all my ethernet connected devices running Norton.
