Five Ways to Get Rid of Cryptojacking Malware

Cryptojacking is a growing threat in 2018 and there are several ways to prevent this threat. Few of the methods to prevent this emerging online threat are discussed below.


Installing browsing extension
Most of the crypto mining malware works from the web browser so we can stop that malware by installing a browser extension. There are few browser extensions like ublock origin & Malwarebytes that will help to block any cryptojacking scripts. If we have these extensions installed on the browser, they will automatically stop those scripts from running on the browser which will prevent the browser from running the mining code. Those extensions are available for free and they regularly update their signature. Since they will automatically filter the mining codes we don’t need to check them manually. Therefore, installing a proper extension will help to get rid of cryptojacking malware.

What is Ransomware & How to Prevent it?

Hackers are looking for a new and easier way to make money by entering on other people's system and ransomware is one of the tools they use to make money by locking the computer of people and organization. In my previous article, I discussed cryptojacking malware and why it is a big threat to information security. On that article, you can read how and why bad guys are injecting code on people's computer to make money from that. Ransomware is another major threat to cyberspace that I would like to discuss this article.

What is Cryptojacking and Why is it Increasing?

Cryptojacking is an online threat where a hacker uses the machine's resources of the victim to mine online currencies called cryptocurrency without their consent. Cryptojacking is one of the growing online security threat of 2018. According to the report of McAfee Labs, there is 629 percent growth in cryptojacking threat in 2018 Q1. Cryptojacking will hijack the processing power of the computer and mobile devices and uses it for mining. Mining cryptocurrency will need dedicated hardware with good CPU or GPU so that it can calculate the hash required for mining. Setting up this hardware and making it run is costly. Therefore, for cryptojacking hackers will use many infected computers for the hash calculation so that they don't need to use their own hardware and resources for the mining. According to Check Point Software Technologies, 40 percent of the top 10 malware are crypto mining malware.
We can see many websites hosting crypto mining code for their profit and it is estima…
