When I started reading about Dark-Web OPSEC, one of the things that caught my attention was how seriously experienced users treat JavaScript.
I first came across this subject through a well-known Dark-Web wiki covering anonymity and operational security. The idea was simple: when visiting an untrusted website, every additional browser capability increases the amount of software and functionality involved in processing that page.
JavaScript sits close to the centre of that problem. A website can send executable code to the browser, and the browser can give that code access to a large collection of APIs. For ordinary web development, this is essential. From a cybersecurity and OPSEC perspective, every exposed capability deserves attention.
JavaScript Means Code Execution
Opening a website involves much more than downloading HTML.
