What is Blacklisting?

Blacklist refers to a list of domains or email addresses for which delivery of emails is blocked. Blacklisting prevents a user from sending a message to the intended recipient. Email delivery management tools can be employed to avoid blacklisting. Blacklisting also occurs when one IP address has been blacklisted. In these instances, the blacklisting can, in fact, spread to other domains.

Almost every day, thousands of websites become victims of cybercriminals. Sometimes, hackers secretly place on the page a malicious code capable of recording keystrokes by users to steal their credentials or information about financial and banking transactions performed on the Internet.

Website Blacklist Check

Malicious software can be so smartly hidden on the website that even experienced developers will find it problematic to detect it, not to mention ordinary users who own websites. On a global level, several companies have developed and maintained blacklists for different purposes. Most of them do have the goal of blocking spam in email systems.

For instance, Google daily checks billions of sites and even warns visitors of dangerous resources in order to prevent theft of confidential data and infecting a user’s device with malicious software.

Reasons for Blacklisting

Websites get blacklisted because they distribute malware in the form of worms or viruses, which significantly affect the performance of computes. Several practices permit easy access to websites, and hackers do not miss to take advantage of it:

  • Web applications

    Even though web applications are meant to provide comfort to the users’ online experience, they allow hackers to embed malware to websites. If not monitored correctly, web applications could become a threat.

  • Servers

    It is also possible for servers to expose a specific website to security threats. Most servers on the Internet work on extremely simple and vulnerable platforms like the FTP servers. There could also be problems with the setup and configurations of these web servers. Most administrators overlook these problems and fail to install the correct security mechanisms. This helps hackers to easily make their way to the targeted websites.

  • Simple passwords

    Simple passwords allow hackers to access a particular website very easily. These hackers effortlessly compromise its security systems and spread malware in order to reach sensitive data.

  • Insecure connections and sniffingx

    Password sniffing has become a common occurrence because of the increased use of FTP connections known for their vulnerability. They allow easy entry of Trojans and “sniff” the user’s login information which hackers use in order to access the user’s websites and spread malware. People who visit the “affected” sites expose their personal data, and websites that are related to them also become vulnerable.
