Today I will fully disclose the new PseudoRandom Domain / DGA of Infector
JS/RunForrestRun we caught just soppted "come-back" in action.
It was started by hundreds infection found via spam emails linked url to://case -1-We reported the osmanoguz.net right away and received cleanup response right away (thumbs up!) But the infections using fotoajanda.com is still ACTIVE, UP & ALIVE, as - per shown below in download PoC:

To check this theory is simple. If we can find that some of those domains are currently alive/registered, then we can confirm this theory. For checking almost 400 domains will not - be easy, that's why I uploaded the script/tools for this purpose in our - Google Project Download Page here --->>[MMD Google Project] The check result burped some domains currently UP & ALIVE, PoC↓:So are the urls download page for this infection up? If the url ia also up, it will not returning 404, then PoC is proved↓

Friends, you will do a very good deed to our internet service if you just BLOCK every Domains, IP Addresses & DNS info reported in this post. We took effort to proof this theory, through some rechecks before exposal.
