What is Blacklist?

A blacklist refers to a collection of IP addresses that are believed to distribute spam. Emails from these addresses are either routed to the recipient's spam folder or blocked. Spam filters are used for identifying blacklists, and these filters use set criteria to identify emails that are believed to be of a spammy or malicious nature.

Reasons for blacklisting a website

Websites get blacklisted when they distribute malware in the form of worms or viruses, which majorly impact the performance of computer systems. A number of practices permit easy access to websites, and hackers do not miss to take advantage of it. The practices listed below are thus considered to be the main reasons for blacklisting a website:

  • Web applications
  • Even though web applications are believed to simplicity the users’ online experience, they also allow hackers to implant malware into websites. Web applications could turn into a threat if proper monitoring is not executed.

  • Servers
  • It is possible for servers to expose a specific site to security threats. Most servers on the Internet function on extremely simple and vulnerable platforms like the FTP servers. There could also be issues related to the configurations and setup of these web servers. A number of administrators overlook these issues and indeed fail to install the correct security mechanisms. This results in hackers easily making their way to the targeted websites.

  • Simple passwords
  • Simple passwords make it easy and “simple” for hackers to access a particular website. They very easily compromise its security systems and spread malware in order to reach sensitive data.

  • Insecure connections and sniffing
  • Password sniffing is now becoming a common occurrence because of the increased use of FTP connections known for their vulnerability. They make it easy for Trojans to enter and “sniff” the user’s login details, which are later used by hackers to access the user’s websites and spread malware. People visiting the “affected” sites expose their personal data and websites related to them also become vulnerable.
