    I love how they went through six stages of obsfuscation, and a lot of effort into hiding what they were doing.... but their payload was literally called "Attack.jpg" like surely they could have named it something at least slightly less blatant.

    • @FilliamPL
      @FilliamPL 3 года назад +8

      Perhaps they didn't care to hide it at that point? I know that obfuscation helps to counter analysts, but when the code is downloading data from a URL, then I suppose it wouldn't've been worth their effort to obscure the name of the download. Then again, they could've made a second download with totally unnecessary data. Either way - this thing is bad (for you)! xD
