[@slygamer01]

The REMCOS developer "discourages malicious use". For sure, everyone will use solely for legitimate purposes.

'sure if you say so' meanwhile no one uses it legitimately

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]

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

[@vannialora3476]

the evolving of rat is so amazing, i remember in late 90's where sub7, netbus and back orifice was so popular and inspired me into hacking. IRC was the channel to go to before and dial up is your connection.

[@ycoihmn6388]

This style of video really helps me with my start in forensics and malware analysis. I love liveoverflow and other CTF summary channels but they often feel like magic in the way they present their findings. Keep up the great work :3

[@Corb4nm0noxide]

So far this is the most fun I've had watching hacking videos. Your analysis is fantastic and I enjoy seeing your process. Keep it up!

Content like this is why I don't have to pay for cable, satellite, or netflix!

But then he would have been on 8-12 screens and typed those 200k characters (hacking is typing fast), it's all hard to follow. It would be like watching the Matrix.

I'm just finding this channel and its quickly becoming my favorite content. Im fascinated with all of this. Really inspires me to get started with basic coding to get my feet wet.

[@definesigint2823]

I've taken apart stuff like this (when I worked in large enterprise) but the samples were rarely more than 3-4 levels deep. This actually looks a lot more like a challenge you'd get at a CTF competition _(perhaps they're getting ideas from each other)_ ?

I enjoyed watching this video and many others. It always seems the videos are pointed directly towards me. I have a lot of these malware problems I believe and have no idea how to fix it nor does anyone I try to explain myself. It’s hard to get anyone to believe me. It’s very hard to see let alone figure out. Like the 0 day malware, redirected url strings, RAT processes, exe and dll problems. I have a lot going on. I’d love to hear back from you somehow and maybe help. I think you would enjoy it
