JavaScript Malware – a Growing Trend Explained

[Andra Zaharia]

JavaScript malware has been building up as a trend for a few years, but in these past 6 months it's surfaced as a trending attack vector.

I've seen users on the forum share news about:

• JavaScript-Based Malware Attacks Your Router's DNS Settings: JavaScript-Based Malware Attacks Your Router's DNS Settings
• Click-Fraud Malware Spreading via JavaScript Attachments: Click-Fraud Malware Spreading via JavaScript Attachments
  
• New ransomware variant coded entirely on Javascript, exploits macros: Virus Alert - New ransomware variant coded entirely on Javascript, exploits macros

And while these threats are easy to understand by cyber security researchers, not everyone has the same background.

For those who want to understand how a JavaScript malware infection happens, I tried to build a guide that explains it clearly. I even included a graphic to help put things into perspective.

You can find the guide here:
JavaScript Malware – a Growing Trend Explained for Everyday Users

Any feedback would be helpful, because I'm sure that the guide can be improved one way or another.

Hopefully, this will come in handy for those eager to understand how JavaScript malware works and especially how to get some reliable protection against it.
