There are warning signs that your home network may have been compromised, such as unusual traffic patterns and slow system performance, but there is now a simple tool that can help you determine if your router or connected devices have been compromised. used to conduct malicious activities. IP checkfrom threat monitoring company GreyNoise, will alert you if your IP address is detected in an internet scan as part of a botnet or local proxy network.
How Gray Noise Contoursthe compromise of a home IP address is often not obvious to the user since you can still conduct normal activities such as streaming, email, and web browsing. However, in doing so, attackers redirect malicious activity through your home IP address and can potentially use your network for everything from account takeovers to spreading malware.
Check your IP address for suspicious activity

Your IP address may also be flagged as being in the GreyNoise database, which is not a sign of compromise – it's likely because you're using a VPN, corporate network, or cloud provider, and the tool can differentiate between an IP address that belongs to a data center and an IP address that is in use. (Note that Apple users viewing Safari with Private Relay enabled will likely see “Possible spoofed traffic detected,” which is also not necessarily a cause for concern. Try checking your real IP address in another browser, such as Chrome or Firefox, to confirm.)
