How to Run a Malicious IP Address Lookup

Every device connected to the internet has a unique identifying label called malicious ip address lookup. Firewalls and cybersecurity solutions use the IP reputation of devices to assess whether they should be trusted or blocked. IPs with a good reputation are known as ‘good’ and those with a bad or suspicious one are known as ‘bad’. There are several ways that an IP can be confirmed as suspicious: launching a denial-of-service attack, dropping malware, hosting phishing sites, showing different behavior patterns and so on. Being able to detect suspicious IP addresses and blocking them before they cause harm is an essential skill for any cyber security professional.

Malicious IP Address Lookup: Identifying Harmful IPs

When you run a malicious ip address lookup, Criminal IP gives you important context about the risk associated with an IP by checking against various blacklists and threat intelligence feeds. You can see what kind of connections an IP is associated with – mobile, residential or work/school – and it also flags the presence of any anonymizers or VPNs like Tor that might be hiding the true source of a connection.

In addition, it checks against ProofPoint’s ET Intelligence Rep List and VirusTotal to identify any indicators that might indicate a broader compromise. This provides valuable insight into the risks of the specific device and can help you investigate further to determine if the threat is more widespread. This is particularly helpful when you’re looking at devices that have a low reputation or are displaying suspicious behavior.
