Love this malware analysis series!
Me too! Amazing series
I love it too!
me too, this guy is really good.
Sir. Can I use remcos rat to hack Android...
Times must be hard, Ed Sheeran is writing python.
Lmaooo💀💀
he looks like an unscuffed burgerplanet
This is ed sheerhan and Seth rogans kid.
You are the hacker version of pewdiepie. Very entertaining to watch.
Nah he looks like a de deobfuscated Ed Sheeran
Ngl, never thought it would be so much fun watching someone analyse and breakdown a virus.
I was thinking the same thing! I might have just discovered my new rabbit hole lol
Woow
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.
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
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
Malicious actors: amma head out
Ethical hackers don't sell hacking toolkits, ethics and all that... 🤷♂️
@@garethevans9789 Pentesting tools are released open source because not only is open source more effective, but it makes sure that the developers are not potentially profiting off of malicious actors, intentionally or not.
Meh, skids are gonna find a way anyway. With our without this program.
I love when John is laughing over the Attack.jpg url
best part
Damn that was fun to watch!! Thanks and keep them coming!!!!!!
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.
Yeah
Okay, but consider this: TOS and TNG are on Netflix.
Scheduling this to start at the same time as the new mars rover is landing... Bold move cotton, let's see how it works out
Bah, totally didn't even realize xD Ah well!
@@_JohnHammond I’d prefer watching this over some rover landing
@@tripplefives1402 isn’t the rover automatically controlled because the delay would be 10 minutes long?
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.
John, as you are very good, you should stand this comment: In Powershell a "split (..)" is a regular expression splitten in string in portione of two characters, ie "4142" becomes "41", "42", in Hex AB
"is this the newest version? because that would be pretty slick"
*immediately scrolls past the version number 3.1.0 showing it is the latest version*
Whatever that quality is that great teachers have, you have it. Never change the format of your videos. I love seeing you troubleshoot and reason through everything live.
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.
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!
I love John’s response when the light bulb goes off and all the hard work comes together. Great video as always.
Great video, I love this series. Also special thanks for zooming in this much, watching code-related stuff on phone is usually a pain, but not in your case. Keep up the good work!
The guy that wrote the script watching this video rn must be like 👁️👄👁️
Remcos: "We specialize in ethical hacking"
Also Remcos: *is used in malicious code*
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
Dude you are simply awesome...it's so enriching for all of your viewers to see your hard work and all your skills, and the best of all is that we can see you enjoying so we enjoy and learn too. Regards from Spain!
Where have you been all my CS degree? This is awesome watching this stuff in action as you do it. I love the content! Definitely going to keep watching!
What a great catch! This is by far the most interesting video I've watched on UA-cam for a very long time. I love this of unedited video.
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)_ ?
After watching this, gained a keen interest in Malware Analysis. Thanks for the awesome content.
Nobody:
Virus Code: * Does malicious stuff*
John: Is it trying to do something bad? HAHAHA
Us: Duhhh John. wtf
Hands down one of the best malware analysis walkthroughs I’ve seen. Watched it twice.
Loving this series. Would like to see some disassembling malware analysis.
This is one of the best educational videos i've seen
Totally enjoyed the video. It was an absolute rollercoaster ride. I love the way you present and explain the details in all your videos. And also none of your videos ever seem to be monotonous even when we are dealing with such mind boggling stuff because of the way you laugh and get excited when you crack/deobfuscate a piece of code. 😁 Thank you so much for taking the effort and sharing the awesome work😊
You make easy to understand videos as you break things down. i really enjoy them.
I have a vague understanding of coding and the way you work is easy to follow.
That was freaking wild, man. You're sharp at this stuff
Pretty sure you need to run the obfuscated version of the AMSI bypass.
Great video, would love to see more of these!
Wow, that was awesome video. It is so nice to see you go through all the steps and thinking while deobfuscing. This RAT is kind of really scary for everything it can do. I would like to see more of this in the future! Keep up the good work
John - This is great content. I really am learning a lot watching you work these out. Keep it up! The masses demand more of this!
I was watching some scam baiting videos and also doing some deep dives into RATs and just... CyberSec/CompSci things in general and found this video. I'm glad I bumped into your channel. Really good stuff you have going on here
i missed the premiere, but this is definitely a blast to watch. Would love to see this more
This was actually fun to watch and go on this journey with you! Loving these videos
Awesome awesome video John! I have followed these de-obfuscation things and when I get to the PE32 I usually say f-it and give up and upload it to virustotal. I'm so glad you went further with this. Thanks so much man!
"Can I get anything out of Melons?"
You can get juice, John. Juice.
Amazing work, you deserve the money from the UA-cam overlords. Literally only commented to help boost those algos.
I love these malware analysis videos. You break stuff down to a fairly easy to understand level for most technical people.
I'm just getting into cyber security and I'm really enjoying your content, thank you.
Absolutely brilliant! I've discovered your channel yesterday and I can't stop watching. This stuff makes me want to give it a shot as well. Never knew that deconstructing programs/scripts (especially ones with malicious intent) could be this much fun! Subbed+bell.
Plottwist: this is all just an advertisement for BreakingSecurity
that url has to be the greatest thing ive ever seen
Wow, that was a crazy ride! Thanks for taking us on the journey.
you got my sub for this. its 3am in the morning and I've watched the entire thing having so much fun. keep on with the good stuff
In the next episode... John rewrites the kernel for more efficient find and replace..... STONKS!
Algorithm, give this man the recs.
It worked. That's why I'm here.
That was a great video. I don't know a whole lot about what you do, but it was super fun watching you do it. Thanks so much!
Keep on doing those Malware Analysis. It's really fun to watch and it's quite educative too!
this is gonna be good
Indeed Indeed :D
Well worth the watch. This is a great video. Please do more. :)
how do you copy and paste into VirtualBox in Windows 10
Awesome work buddy !!! watching your videos while at work coding my self ... thanks for the vids
Damn, I just watched over an hour of stuff I have no clue of and I still feel educated and entertained.
It even kinda makes sense, when you talk about it and explain some stuff.
Thank you very much! :)
"guys, you might think i'm dumb" LOL exact opposite.
Attack.jpg, that was hilarious
You know so much about so many things... I've learned so many things in the few videos I've watched so far. Super, super inspiring.
Brilliant. You make malware reversing so fun to watch.
59:31 No. That's the noun "licence" as opposed to the verb "license". It's a British thing.
THOSE DOWNVOTES....GTFO...this dude is a legend
This is crazy. I've learned more about malwares in a few vids I saw from you, than the time I spent trying to get into the field years ago. I'm a fulltime dev now and have been working for over 7 years. Reminds me of my recent grad days where all I wanted was to understand this. Much easier to follow now, and damn, learning so much so quick now. Props to you.
Really interesting video, thanks !! I'm impressed at the obfuscation job done on this malware it's impressive
That's a rabbit hole if I've ever seen one haha great stuff man!
If only it (the rabbit holes) were rare. 😥
Follow the white rabbit!
every single line "I don't exactly know what is going on here" so basically this guy is just us trying to understand code. got it.
Your knowledge is very impressive! Love learning from guys like you!
Fantastically enjoyable to watch you solve problems as always . Thanks John
John: releases a video with malware analysis
Me after watching a video: *Lemme check real quick whether notepad.exe is running in the background or not in Task Manager*
Imagine using windows 🤔
@@benricok Imagine thinking that exploit-db had 0 results for Linux 🤔
@@Reelix I didn't even mention an OS? I am aware that Linux isn't perfect as so with every software product (opensource or not). The worst thing you can do to your security is to be over confident in your defense.
@@benricok Imagine being a pompous asshole. Some people want to, you know, play normal games on their computer.
@@theluckyscav3487 I mean linux gaming has come a long way, but it still needs some time to flourish
I have basically no connection to it-sec, but this stuff is addictive ... love the videos
Found you on the recommanded page , love it !
I binge your videos every day all day at work. Gets me through the day and I learn some new/cool stuff.
Please mahn ... we need more malware analysis like this!! ... and also ... C source code analysis (something like that)
Waiting for it :)
This was so fun to watch. The sketchy url was very funny, fitting pun on with the ‘holy cow’
I'm learning to program in college rn and I just ran across your channel and my God man the length people go to, to scoot around anti-virus software and download shit on your computer is insane.
Although seeing how all these functions are working together is awesome!
Keep up the good work!!!👍
"I don't like these advertisements..." "You didn't see this here folks!" "Not in a John Hammond video!"
That was more than a safari ride! It's awsm
Really fun to watch ! Looking forward to see more !
complete amazing by the skills you have for it. many questions i can think a bout it. good work man love it
Legend
I honestly never appreciated Search and Replace until today. Everything is so clear now!
19:35 One learns more every day
33:44 What the hell this is hilarious
44:00 I hope you saved
56:13 I judt read a Online Keylogger Started so I guess yes
1:01:52 Oh so test hacks? Was this retrofitted to be malicious or you just were smart?
1:03:08 Imagine if Jim's Scammers used this crap. My god
1:10:00 Fresh off the oven and unobfudcated
This was fabulous! I hope to see more!
Enjoying the malware analysis videos. Very informative.
was great :)
Amazing stuff. Learned a lot from this video.
I have a question: how did you come across this script? Did someone give it to you? Anything like that?
Loving these malware analysis videos, John. Keep 'em coming!
Watched the whole thing from start to finish - loved it! Make more!
Definitely a lot of fun. Thanks for sharing man!
I have no idea what I'm watching but I'm enjoying it :)
It's actually not a bad way to learn, at least starting out - if you're interested. I have a background in software engineering, but I only understand maybe 75% of what's going on.
The Title is like
Asking if water is wet LOL
Pls keep up the malware analysis videos! Its so fun to watch!
Hi John, Love these kinds of videos! Keep making them! Great discovery! And current! Hahaha, that was unexpected. Looking forward to some more content.
I just want to know how it’s humanly possible to obtain the level of programming and CS knowledge needed to be capable of doing what he does in this video
It’s depressing but motivating also!
Yeah imagine who made this
Actually, not too much. Deobfuscating such stuff is not very complicated, but he is still doing a good job. But tbh .. most parts could be much faster by debugging functions step by step instead of trying to deobfuscating every var and func.
so where did you get the jscript if it was only released so recently...
i wanna know too
The actual payload was hosted remotely, so that can be updated separately.
John Amazing teaching methods so clear and precise i was able to follow you all the way to the end. Your amazing man, I was looking fr the next new thing to get into its malware analysis. please show me more i might be a natural at this
Nice. I really impressed at final "detective" processing :) Keep it that way
Where do you get such fresh samples? That hash isn't even on VT yet.
Plot twist: John actually wrote it
BTW... next thing. Do remcos guide, analysis and stuff
I love your videos which are not preplanned... It gives us an option for us to know how you actually resolves when you are stuck....
Hope to see more of these videos! Tons of fun
