7 Ways To Protect Against Cryptojacking

Right now, your computer might be using its memory, processing power, and your electricity to generate money illegally for someone else! It’s called “cryptojacking” and it targets the rising popularity of cryptocurrencies. Cybercriminals harness the power of your computer’s CPU for the sole purpose of mining cryptocurrency. Over 2,500 websites have already been accused of using visitor’s CPU power to harvest cryptocurrency. In a way, cybercriminals are creating their own ATM out of your computer.


7 Ways To Protect Against Cryptojacking

What is Cryptojacking?

Cybercriminals who use cryptojacking target websites that generate a lot of online traffic.  They then infect the website with malicious code. The infection is not designed to steal your private data, but to harness the power of your Computer’s CPU in order to mine cryptocurrency. After the currency is mined it remains untraceable and is sent back to the cybercriminal.

Cryptocurrencies such as Bitcoin, Litecoin, Monero and Etherium can be obtained by cryptojackers and as the value of cryptocurrencies rise and fall; we must prepare to witness more of these cyber-attacks. How can you protect yourself and prevent cryptojacking?

How to Protect Your Computer Against Cryptojacking

  1. Always use antivirus software. Antivirus software detects the presence of malware and blocks many viruses before they can infect your computer. Make sure you keep your AV software up to date.
  2. Set software and apps to update automatically. Software and apps are constantly getting new security updates. Keep them up-to-date with automatic updates.
  3. Never install software or apps you don’t trust. Always install or download software and apps from trusted sources. Read reviews on the software and the site.
  4. Don’t click links without knowing where they lead. Clicking on links in spam or questionable emails can leave you vulnerable to phishing attacks.
  5. Be careful about visiting unfamiliar sites. Always use caution when visiting a website for the first time and be wary of any site that asks for personal data.
  6. Use an Ad-Blocker. Some ad-blockers help defend against cryptojacking by blocking mining code. Read reviews and check trusted sources before installing any online tools.
  7. Monitor your CPU usage. Open the resource monitor on your computer to check if the CPU usage is abnormally high. For Windows, it’s called “Task Manager” and for Mac it’s the “Activity Manager”. If you see a spike in CPU Usage when visiting a website or if you have everything closed but CPU usage is still extremely high, then you may have a crypto mining malware problem.
