From ZDNet:
Around half of the websites that use WebAssembly, a new web technology, use it for malicious purposes, according to academic research published last year.
WebAssembly is a low-level bytecode language that was created after a joint collaboration between all major browser vendors.
[...] However, while the vast majority of samples were used for legitimate purposes, two categories of Wasm code stood out as inherently malicious.
The first category was WebAssembly code used for cryptocurrency-mining. These types of Wasm modules were often found on hacked sites, part of so-called cryptojacking (drive-by mining) attacks.
The second category referred to WebAssembly code packed inside obfuscated Wasm modules that intentionally hid their content. These modules, the research team said, were found [as] part of malvertising campaigns.

I have js blocked on my computers - but you may have noticed that I spend quite a bit of time here. Javascript is most certainly not required.
