How to Identify Malicious IP Connections
Identifying malicious IP connections is one of the most critical skills in cybersecurity. Malicious IP addresses can be used to launch denial of service attacks, phishing attacks, botnets and other cyber threats. Blocking malicious IPs can significantly reduce the risk of a breach by preventing harmful activity from accessing your network.
Identifying malicious IP connections are by different types of behavior, such as hosting phishing sites, scanning for vulnerabilities, dropping malware, launching DDoS attacks and more. Using multiple threat intelligence feeds and examining the DNS lookup name can help you identify an IP that is likely to be malicious.

Additionally, observing the same IP address engaging in benign and malicious activities over a period of time can provide an indication of its true nature. By leveraging this data, it becomes possible to better detect malicious IPs and eliminate false positives.
Another way to determine if an IP is suspicious is to examine the ISP it belongs to. By looking at a visualization of IP addresses grouped by ISP, you can see distinct clusters of benign and malicious activity. This helps to improve the model’s understanding of ISPs, allowing it to differentiate between them better.
Using the data provided by AbuseIPDB, it is possible to train firewall and cybersecurity solutions to repel these attackers without slowing down network traffic. This allows for a more efficient and robust protection against these kinds of threats and prevents the breach from occurring in the first place.
