Readable text format at a much lower level of abstraction than javascript currently is at right now.  Different is different.<p>It&#x27;s not so much about spying on your computer and gaining extra access, it&#x27;s obvious (short of implementation bugs) that you won&#x27;t gain any additional privileges that way.<p>But what you will gain is a way to obfuscate <i>extremely well</i>  &quot;report such and such to some webserver&quot; in a way that&#x27;s difficult to detect.  For example, you can hide the entropy inside of a fairly innocent looking URL and without a lot of digging you won&#x27;t know <i>what</i> that entropy represents.  It can look like just a plain jane resource request and the webserver can serve up the exact same resource no matter what the entropy is, but also record that entropy for a back-channel way of exfiltrating information from your browser.<p>Finally, it opens up a whole new world of compiler attack.  Right now the attacks against wordpress involve writing some information into a file and making it look &quot;weird but I don&#x27;t know what it does so I&#x27;d better not touch it&quot;.<p>What happens when breaking into a wordpress install means that you can execute the equivalent of the untraceable compiler login exploit insertion attack?  You can&#x27;t perform this attack without 1) a compiler and 2) a low level target that&#x27;s hard to understand.  You don&#x27;t even need to perform a stage 3 attack which is the most sophisticated, a stage 2 would do fine.<p><a href="https:&#x2F;&#x2F;www.ece.cmu.edu&#x2F;~ganger&#x2F;712.fall02&#x2F;papers&#x2F;p761-thompson.pdf" rel="nofollow">https:&#x2F;&#x2F;www.ece.cmu.edu&#x2F;~ganger&#x2F;712.fall02&#x2F;papers&#x2F;p761-thomp...</a>
