In the digital era, a new and strange threat looms over all our computers and power supply. Your PC may have already become an algorithm-solving machine for hackers mining for cryptocurrency. No PC is safe from the cryptojackers.
The paranoia is justified and stringent measures must be taken to protect your computer against such cyber threats.
Lately, there have been too many full-blown cyber attacks in the form of data leaks, security breaches, password managers failing, systems becoming victims of cryptojacking. It's scary!
Now, this question may arise — "what the hell is cryptojacking". Let me shed some light on the matter before getting to the solution.
Nefarious hackers are lurking around, looking for a system they can hijack for mining cryptocurrency without the knowledge of its owner. This is what the digital world is calling cryptojacking.
It was not so simple earlier where the victim had to install some malicious software for the hijackers to gain access to the system.
Fun Fact: It's believed that Satoshi Nakamoto, a coder using this pseudonym, created Bitcoin in 2008. The world is still trying to know his true identity.
How Does Cryptojacking Work?
Here's how such a malicious code looks like:
Using the above code, CoinHive hackers can mine for Monero, a cryptocurrency that has a price of $409.37 as of today.
Here are two ways you can protect your system from cryptojacking on the Firefox browser.
1. NoScript Security Suite
This will allow active content to run only from the websites that can be trusted. NoScript Security Suite will block all the malicious webpages and keep your system safe from cryptocurrency miners.
This security suite works on browsers such as Mozilla Firefox, Microsoft Edge, Tor, and Safari. Also, it works for the Android version of Firefox.
2. Mining Blocker
This crypto-mining blocker prevents cryptojackers from accessing your system and suck the juice out of your CPU and power supply, making a dent on your monthly electricity bill. You can also deactivate the add-on temporarily if you are in the mood of mining some coins for yourself.
Note: Globally, cryptocurrency mining on systems without the user's consent is not illegal yet. However, a few countries have banned this thing. It's extremely unethical and criminal because it breaches your system and power supply without consent. So, remember that you cannot lodge any legal suit against cryptojacking. Hence, precaution is the only care.
