How to Identify Cryptojacking Malware?

There are several ways to identify the hidden crypto mining malware on our computer. We can either detect and identify that malware manually or by using the third-party antivirus or antimalware tools. These are the few ways to identify the cryptojacking malware on our computer.

Monitoring CPU usage

If we see unusual CPU usage behavior then our computer might be infected with cryptojacking malware. Usually, there won’t be much CPU usage when the computer is idle. We only see a spike in CPU usage when we are using heavy programs, so if we see high CPU usage on our computer when we are not using any programs on the computer then this might be the result of cryptojacking malware. We can manually monitor the CPU usage of our computer when we open any web browser or open any website. If the CPU usage is increasing when we open any website then there might be cryptojacking code on the website, we can then block those websites from being loaded on our computer. If we see high CPU usage when opening a browser or any other application, then this might be due to the hidden mining codes in that software. Monitoring CPU usage is one of the best ways to identify the cryptojacking malware.

Analyzing fan sound
One of the ways to detect crypto jacking malware is to monitor the CPU usage but checking CPU usage frequently might be impractical. Instead of checking CPU usage we can also check the sounds of a computer fan. If the computer is infected with cryptojacking then it will increase the CPU usage which will result on the increasing temperature of the CPU so the cooler fan of the computer will rotate rapidly making the sounds notable. If we can hear the loud noise of fan frequently then our computer might be infected with the cryptojacking malware. There are lots of fanless laptops and ultra-books available, also the mobile devices will not have a fan to cool down the CPU. For that kind of computers and mobile devices, we can monitor the temperature of CPU rather than monitoring the fan sound.

Analyzing the performance of the computer
If the computer is infected with crypto mining virus then one of the major symptoms is the slow performance. Since most of the CPU will be allocated for the mining purpose computer can’t handle the assigned task and the performance of the computer will reduce. If our computer started performing slowly suddenly then it can be the result of cryptojacking. When we open any website infected with mining malware it makes the browser and other application very slow. Sometime the browser might freeze due to high CPU usage by the application. With the modern operating system, we can see the CPU usage of individual tabs on the browser so if any tab is making the computer slower, the website opened in that page might be mining the cryptocurrency.

Most Popular Authentication System And Their Problem, They Are No Longer Secure

Although there are lots of method and devices available for authentication, each of the authentication that we use has their own limitations. Below are the authentication systems that we are using and their limitations: Password ID and password are the most common and widely used authentication method. Although it is one of the widely used methods it carries huge security risk. One of the biggest problems with this system is that anyone can guess the password and can be shared knowingly or unknowingly. Also, the no. of the password will increase with the no. of service that user uses. It is insecure to use a single password for all the websites, so it is recommended to create a unique password for each website. Users cannot remember all the passwords that they have, and they might write it somewhere, which can later be leaked. The password can easily be stolen online by using phishing sites and can be stolen with keyloggers. We can create a strong password by using long characters, bu…

Best Practices to Avoid the Phishing Attacks

In my previous article, I posted about the phishing attacks and different types of phishing attacks. On this article, I will write about the best practices that will help us to control the phishing. Phishing can be prevented somehow if we do follow best practices for anti-phishing. Some of the best practices for anti-phishing are listed below.

Maintaining Firewall & IDs It is mandatory to maintain proper security infrastructure by installing and maintaining firewall and intrusion detection system. It should also provide security against malware. Awareness Awareness is one of the major things that we need to mitigate the phishing attack. New Intel Security study demonstrates that 97% of individuals can’t recognize phishing messages. Therefore, it is very important to make people aware of phishing. Updating Web Browser The web browser is one of the application software where users spend most of their time online, therefore, it must be regularly updated, and security patches must be ap…

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.

Installing only trusted applications
Another big source of crypto mining malware is untrusted application…
