Blacklist Checkers

Cyber Security Degrees

What is Blacklisting?

A blacklist is a list that blocks email delivery to certain domains and email addresses. Blacklisting blocks a user’s ability to send a message to its intended recipient. Blacklisting can be avoided by using email delivery management tools. Blacklisting can also occur when an IP address is blacklisted. These blacklistings can spread to other domains.

Cybercriminals can take down thousands of websites every day. Sometimes hackers place malicious code on a page to record keystrokes of users to steal their credentials and information regarding financial transactions made on the Internet.

Malicious software can be hidden so well on websites that even experts will have trouble detecting it. This is not just for website owners, but also for those who aren’t web developers. Many companies maintain blacklists that are used for various purposes. They all have the same goal: to block spam from email systems.

Google, for example, regularly checks billions upon billions of websites and warns users about potentially dangerous resources to protect confidential data or prevent infecting their devices with malicious software.

There are many reasons why your domain/IP has been blacklisted

Websites that distribute malware, such as worms and viruses, are blacklisted. This can significantly impact the performance of computers. Hackers can gain easy access to websites through a variety of methods.

Web apps

Web applications are intended to enhance the user’s online experience. However, hackers can embed malware on websites. Web applications can pose a threat if they are not properly monitored.


Servers can also expose websites to security threats. FTP servers are the most vulnerable and simple platform that servers use on the Internet. These web servers could have problems with their configurations and setup. These issues are often overlooked by administrators who fail to properly install security measures. Hackers can easily gain access to targeted websites by this.

Simple passwords

Hackers can easily access websites by using simple passwords. Hackers can easily compromise security systems and spread malware to access sensitive data.

Unsecure connections and sniffing

FTP connections are known to be vulnerable and password sniffing is now a common occurrence. They enable Trojans to be easily installed and can “sniff” user login information, which hackers can use to gain access to user’s websites and spread malicious code. Visitors to the “affected sites” expose personal data and other websites are also vulnerable.

Comodo cWatch – Prevents blacklisting and executes a website blacklist check

Websites can be infected with malicious computer code by malicious hackers and automated robots. Search engines, security companies, browser manufacturers, and browser makers will block users from visiting compromised websites to protect web surfers. Blacklisting websites can happen for many reasons. These other reasons include the fact that hackers can use websites to send spam and phishing emails, as well as to persuade Internet users to visit fake banks sites, buy pharmaceutical drugs, and so on.
