There are many different types of blocklists and blacklists that focus on blocking malicious users, bots and spammers. These are usually based on a combination of evidence and behavior. Some lists are very broad in scope (like Spamhaus’s XBL) while others focus on specific activities like listing proxies, TORs and VPN services.

A live malicious IP list way for an organization to be added to a list is when their email server or network gets compromised. Malware can then spread to a huge number of devices within the network, often using IP-related services that attackers use to gather information about the victim’s system and evade detection.

Live Malicious IP Lists: Keeping Up With Active Threats

Detecting and identifying this malware activity requires a lot of intelligence about the environment that an organization is operating in. One of the most important pieces of intelligence is knowing what services an attacker uses to connect to their victim systems, which can be extremely useful for detecting anomalous behaviour that might indicate an infection.

Using a live malicious IP list can help organizations proactively identify compromised systems and prevent malware from spreading. Using the list in conjunction with the threat intelligence data from Veriti’s IPS enables a security team to uncover early signs of an attack and take preemptive action. Choosing a live malicious IP list with a small age of unique IPs can also reduce the risk of false positives on firewalls and email servers.
