🫠 ERRATA:
- 51:43 I meant the opposite. You're copying data from your SOURCE into your DESTINATION. Y'KNOW, LIKE A NORMAL PERSON WOULD SAY.
CROOOOOOOOOOOOOOOOOOOW
Ahhh this is only for the lifetime subscription. Dang
YES
see you next year on your next upload
CROW'S FIRST SPONSER???? LETS GOOOOOOOOOOOO
YEAHH!!!!!
2:37 I mentioned this in a seminar and everyone including the professor talked about me like I was crazy or I’m a bad guy or that ethical hackers wouldn’t dream of doing such a thing. We just run nmap and metasploit…don’t mean to vent but it’s good to know I’m not crazy for thinking that way
This is one of the few Tutorials I know that actually are fun to watch, love the way you make the videos
I love the shear joy CROW shares when everything comes together at the end 😁
Bro I literally thought of this and was trying to make it yesterday how tf am I this lucky that crow is covering it
This is the only channel i know where sponsors doesn't feel like garbage, my lifetime subscription to MDA is going BRRRRRRR
Can you do persisting next. @crow
Another masterpiece. I have learned SO much from these videos and what I have read from the discord.
Keep coming out with these videos. Love them 🔥
Ohhh yeaaaaa we need lots of videos like this about modern red team and malware development please
never have i clicked on an hour long youtube video faster than i have with this. I'm in a for a treat!
This is f*cking awesome, never knew this was even possible lol, was literally creating a new process to delete my malware for self deletion 🙃 keep it up crow best mal dev on youtube for sure
The Maplestory BGM is what keep me watching
I'm itching for the 4th video in this series. Thanks for the videos crow.
A wise man once said "With great power, comes great electricity-bill"
Perfect content, Perfect quality, Perfect explanation 🔥
Bro the video editing was great, awesome new vid!
oh my god mom cancel my plans new crow video just dropped!!
Crazy production, information and comedy
Amazing video, keep up the good work
i mean, watching this at like literally 3 am and so inspired that im gonna try it out my self instead of sleeping. amazing content bro keep it up
What a interesting stuff!!!!!!
I learned a TON!!!!!!!!
CAN'T WAIT TO SEE YOUR NEXT VIDEO
Just yesterday, I was wondering when's your next video coming ... And today I get this notification! 😊 Thank you crow! 🍻 😊
Great video and congrats on the sponsor man keep it up!
Let's go man this channel is amazing keep on the good work fr best channel on UA-cam damn
you're my hero.
Babe wake up new crow just dropped!
YAYY!! NEW CROW VIDEOO WE MISSED YOUUU
Your's is the only hour long video i'd watch
great video, thanks a lot 👍
So, intead of self deletion I had an idea once of a program that would embed some data inside the executable file. I wonder if it is possible to do with alternate data streams, would be cool to have a single exe that saves all the data it generated traveling between different machines.
I saw a one hour video with
A language i dont use
A field i am not in
terms i have no clue about
OS i dont know much about
10/10 will watch again.
This video is amazing man, keep it up :)
LET'S GOO C:
:D
i love the maplestory music
Hello, thanks for the video,
When getting a handle to the file, from where did we find that we can give the CreateFileW the values (delete | sync) for the dwDesiredAccess field, since I haven't found that documented anywhere !!!
It's just remembering me of 29a VX group in 2000's 😃
it is illegal to delete this video!
Crow=Legend!
Hi crow great content!! I really enjoy your videos,Can you do a video about how memory works, virtual memory, pages and memory protections?
these are the best of the whole yt prove me wrong
Like always awesome vid! btw what IDE do you use?, and also, can you do a video on how to setup windows 10 for malware development? cuz downloading the C++ compiler (gcc) is making me want to "self delete" if u know what I mean
Gotta take another crack at this from the beginning. Somehow my smart dumbass got the program to work but in reverse. I’ve played around with it and even tried some else statements but still a great video. I learned a lot…just gotta rest my eyes…
I’m an idiot lol. The joys and pain of coding. Smh
HYPEEEE NEW CROW VIDEO
Woke up to a new video let’s go
All your videos are amazing dude thanks ! Keep it up !
However here I don’t get why we need ADS, can’t the malware goes to deletion phase directly ?
Sorry for asking, but the file that is still being viewed, it can not delete itself in the middle right? the deletion is only possible after the executable is done running.
but this is a problem, if a file is being gives a command for self deletion, it is technically still running, and running file can not be deleted. Is it some sort of extrafile buffer? like, windows gets the command to delete and it does after the file is done running?
can you make a video similar to the buffer overflow video but explain rop gadgets, rop chains, and rop in general
I cant believe I watched a 1 hour video involving a language I don't even code in on a daily basis (I do code in C++ rarely for a variety of reasons so don't go all: "C++ is superior" on me)
C++ is superior
C++ is superior
C++ is superior
Lord Have Mercy on My Analyst Soul 😧
Why write in assembly instead of implementing it in C like the kernel does? It's way more readable, you don't need to deal with linking in an assembly file, and there's no "extern"s required in your headers.
Also, it's kinda overkill, but another fun approach to anti-anti-debugging would be to hook the program's anti-debugging function and force it to always return false (or just patch the binary). Anyway, loved the video! This was super informative. I've had a lot of issues with my non-malicious process injection getting flagged by Defender. I never even thought to re-implement suspicious imports myself.
holy shit holy shit holy shit holy shit
CONGRATS ON YOUR FIRST SPONSOR DUDE
YES CROW
mom crow finally uploaded a new vid
ur vids are great! i feel violated by the stream of information that we have access too in this day and age :^)
Another banger!
Awesome content 🎉🎉🎉🎉
This is amazing content! I wish I found you sooner...
why do I think of you as my personal mentor😊
I am crying from happiness at the moment, I am truly happy that you got your video out which you worked hard on crow. I hope you take a break and dont suffer from burnout my brother :)
is it possible to patch memory that is protected by vmprotect ?
Me compiling a hello world program and executing only for the executable to get blocked by Windows Defender as malware.
Also me: IAM MALWARE DEVLOPER \o/
Heuristics is most power come from at antivruses.
very cool very pog very based
I LOVE YOU, CRYPTID
the pricing is absolutely insane
Been on the platform for a month now and can say that it's completely worth it, there are cheaper options though (Sektor 7 for example) though they're not as in-depth/up to date as maldev academy
this vid is god tier.
Большое спасибо за твои видео 😼💖
Thanks for the tutorial and infecting me with AdWare at the same time. Great! = D
I'm trolling. You do you boo boo. Videos are very entertaining even though I don't know wtf you are talking about. (I do, again trolling) You owe me a motherboard.
4:40 what is that obsidian theme tho 🔥
@@mathis5281 Thanks thats exactly it!
Hey awesome tutorial ! is the source code available? i couldn't find it in GH
You forgot to tickle Mr. Rat. He will not be happy. I hear 22kHz here. (Only people from discord server understand)
Nice 👍
How'd you learn C and Assembly? MalDev Academy or TCM. DeWalt, Alex and the crew at TCM are awesome.
So is there any defensive software you would recommend? That primarily uses behavioral heuristics without having to be online...‽
EDRs, XDRs and AVs rely on being online to update their signatures and whatnot, having them offline can make it harder for them to pick up newer malware strains
@@lavender0666 automatic updates feel like a good attack vector, heck if that were my thing that would be one of the first ways I'd try and get in, by emulating the antivirus vendors servers, even if I failed I'd be able to figure out what I was up against.
@@petevenuti7355 that's not a new thing, they're called Trojans and they've been around for decades
A SPONSOR AND CROWS RAT VOICE REVEAL. TODAY'S A GOOD DAY.
kindly give us a roadmap "how to learn cyber security from scratch to advance"
Ooooh noooo, you missed UEBA!!!
Bro do you also have courses?
This gonna last me for the next month
Make a video how malware can tell if the OS is updated using windows update.
YIPPIEEEE
I’ve used these techniques and am now in jail.
drop more heat!
cool videos
I shall become a rat amongst men
HOLY MOLY 1 ENTIRE HOUR NOW I GET WHY YOU'RE BEEN GONE SO MUCH
GET THAT BREAD BRO
Tbf, in a war malware can be handy. Like let's say hypothetically Russia starts a war with another country, but all their electronics suddenly show a ransomware message
Cyber Warfare is a real thing already, there are state sponsored hackers in all governments (see NSA/CIA for US)
777 like btw. I use arch btw. Wonderful video btw. U got hr ass ur first sponsor congratulations 🎉🎉🎉🎉🎉🎉🎉❤❤❤ btw. (I use arch)
can we have a video on how to heck Roblox please 🥺
28:07 there actually was a 1337 process on my pc, i was wondering why it didn't and i was getting a handle wtf
The process is different for everyone, they're not hardcoded in but given on runtime (process creation)
crow can you make a video on how to hack into the hexagon >:)
hacking is 4 nerdz and ill eagle no tanks (they're in my walls listening to me)
Their AI needs to train on a protection less computer so it can best serve both sides.
❤
Why renaming the default datastream before deleting it ?
Can't you just delete the default one ?
2:45 can malware be a form of self defence?
you're gonna have to expand on that, if you're attacking someone without explicit permission then that's a crime
@@lavender0666 Russia. Well it's military. Didn't want to get attacked? Then should had not started a war in 2014 or escalated it.
@@principleshipcoleoid8095 Look up cyber warfware. If a country is attacking another country's assets as soldiers/military personnel then that's okay but if you're doing vigilante stuff that's a legal gray
is there any financial in malware dev (this is for educational purpose)
red team developer
OH AH!!! 10% OFF ETERNAL ACCESS!!! LETS GOOOOOOO RATS!!!
Woooooooooooah
cool
