"Skip ahead if you don't want to watch me suffer"... you have CLEARLY misunderstood why I'm here ;)
Hahaha me too!
Always a good feeling to see other coders struggle aswell on tiny mistakes :p
@@furioznetworkz945 ye, as coders, we make mistakes
🦆
I like that the videos are not scripted please make more of a Malware Analysis
+
Nice try, hacker!
@@johnhunt1813 ?
None of his videos are scripted bro, you can see in like the pico CTF playlist, he improvs on the way
@@harmitchhabra989 most actually are ;)
I cried when he downloaded update.exe as kaspersky.exe
I was impressed that he catched it that fast.
13:28 he makes a folder named Kasperky instead of Kaspersky. He does not catch this tipo and gives up. AAAAAAAAAAAAAAAAAAA
I love how John can easily edit the parts he messes up out but he still doesn't and leaves it in. I love seeing your internal thought process when it comes to solving problems.
I can see two reasons why running update.exe at ~15:00 didn't work: 1) it needs three args, the first of which being the pid (you only gave two), and 2) you misspelled the Windows/kaspersky directory as Windows/kasperky.
I caught that too!
Another one who caught that typo there!😂
You forgot an s! You forgot an s! You forgot an....oh forget it, you can't hear me.
@@natetronn 😂😂😂
i felt so smart when i saw that mistake haha
Yaaaassssss,
Another malware analysis wooooooo
File Description: b
I got hacked and I really cant get enough of this content, it's just so interesting. As far as I know your the only one making videos about this stuff that are really fun and enjoyable. Thanks dude
ohh welcome to a new world
You were hacked by a grammar nazi who hated you for using "your" instead of "you're". :')
@@liesdamnlies3372 Are you confessing the crime? hahaha
@@liesdamnlies3372 The hacker probably added a script that would autocorrect all cases of "you're" into "your" so he would get random hate online. :P
John: *disables windows adapter*
Me: *internal screaming* _You should do that in the VM settings_
@Throwaway123 bruh yes
And he made a typo in the directory name: "kasperky"
@Throwaway123 It could be because he has more experience with Bash scripting. The zeroth argument ($0 ) is automatically the path to the script. I also come more from the Linux-world and I would have thought the same thing in his place...
I am a beginner Python programmer and I like to watch you videos because they make me feel like I understand the things that are happening, but I am just absolutely clueless as to what's happening. Love it
John: Here is what I think you should try with this: Determine what the config url turns out to be, then see if you can slap your own command and control server together, to send you an email. That would be cool. Like, tame the malware and do your bidding. Another approach would be to fake an update server, and see if your can push other code to your VM that way. It would give viewers a nice insight into how the remote (usually hidden) aspect could work in theory. That would also make for a great hackthebox style box as well!
You are quickly becoming my new favorite person to watch when I get home from work. Great stuff!
The content usually isn't that interesting to me, but with that enthusiasm of yours i just cannot get enough of it.
Your videos are so exciting! Not to mention extremely informative. This makes your content so unique!!! Thank you so much for everything you do!
You have one of my favorite channels. The other happens to be David Bombal. I can not express how grateful I am to have you guys as resources!
These videos are honestly so great - even if you can grasp all the technical coding stuff, it’s still so educational!
Really nice John, been with your channel since 70K~ and am really not suprised it grew that much. As for this series, I love them, can't wait for the next one! Never responding to video's but just wanted to let you know how good they are and that you should definitely keep it up! Kind regards
omg... North Korean did this.
"완충기" which means buffer in Kanji sound 緩衝器.
South Korea use "buffer" "버퍼[buffer]" as it is pronounce in English when programming.
"오유[O:YU]" means error, which is "오류[ORYU]" in South Korean.
"량[Liang]" = Quantity is "양[Yang]" in South Korean.
North Korean has liquidization in ther R, L, I sound.
This is so creepy. Wehn you type kaspersky in youtube, many TH-camrs instroducing "Hey you can use Kaspersky for free!" in Korean language. This is how they works...
Really interesting. Might very well be a false flag though.
I have to disagree with your theory. This is chinese malware. Check out the one password the developer of it uses. "shengui foresight 1988 2 27" (spaces added post for clarity).
I have to agree, North Koreans are notorious in their search of escaped citizens around the world, and considering there was not program ran, it could be setting up a bot network to monitor email activity and passing/notifying information to the people sitting and waiting for the positive results. Just a hypothesis, would need to make a deeper analysis to be sure.
Shen means god in Chinese, GUI don't need explanation, although North Korea can make malware, Wannacry ransomware originated from there. It is possibility that chinese IT guy got kidnapped or is coworking with N.K._
Keep the malware analysis coming! Love it!
Very interesting videos! Love seeing how this stuff works! There was no way I was going to skip ahead...
Amazing Content John, I appreciate it I've seen a lot of channels related to this niche but your channel just looks unique and you're very natural unlike the others :D
I've been starting to get into malware analysis myself, but it all seems so daunting. These videos help dramatically. Thanks for releasing this high quality, entertaining AND FREE content!
Keep up these great and expansive videos! I've been learning a lot from them and I appreciate the work you put in!
John: download two time kaspersky.exe instead of upload.exe
Me: scream at the monitor for 3 minutes straight
John: you should told me!
Me: I did it John, I DID IT.
Same situation here. 😂
LMAOO samee
keep up the malware analysis! I learn so much from each video!
been waiting for another one.
love the content, thank you.
Great content, as usual! I wanted to drop a note to say though, that ending track is bomb!
Most underrated TH-cam series. Keep up the good work!
finally a constructive vent for my paranoia (brought me here)
Same
this content is really interesting, really shows the thought process oh how you do it and even the mistakes you could make
fun videos
Great video showing the process of breaking down the software! The program itself didn’t run because it had a check for internet right at the beginning. If it had an internet connection then it would have run but that’s a problem in itself. I program a lot in C# and recognized a lot of the code that was written while you were going through all of it. It was an overall great breakdown video to watch and see your process for this type of thing.
Hi 👋, I was wondering what was all that ip addresses ? Are they real people ips ???
Thank u 💓
Yup... agreed. That's where a proper isolated internet accessible VSwitch would have been great.
@@blazi_0 Yes? He literally showed you the locations of some of them...
Last 30 minutes were tons of fun. ;) Keep it up!
Love your videos man great content ! Just way too long for me compared to 15-30 minutes videos i’m used to on similar content but that’s just me. Keep making more content though it’s super helpful !
yes I love reversing ! and seeing the process you use .
I am so thankful i found this channel....I got a premium sub for THM and am taking courses to learn everything I possibly can.... thanks John 👊
Oooh, great video John. Thanks for sharing, friend! :)
I had just installed the malware 2 weeks ago Lol, I figured out what's happening to my computer quickly and I shuted it down then opened it up and ran my windows defender again and started cleaning and voila.. My computer is clean
Love you from Egypt.
Keep it up
I don't know if anyone else mentioned this before, but apparently "Shengui" has a number of potential meanings depending on the accent marks.
In chinese it can be: lady's bathroom (shēn guī), miraculous (shén qí), ghost/divine ghost (Shén guǐ), divine turtle (shénguī), etc.
In korean it can be faith (sin-ui), god (singwi), etc.
Seeing you at work is awesome
Think I’ve found my new favorite channel
It's a great series, keep doing it please!
Always entertaining, love your content
I’m liking these malware analysis videos
Protip, the kansas pin on the map is just the center of the US and default when not knowing any better. There is a farm there and the local sheriff will yell at you if you try to say they are cyber criminals.... again :D
Thank you for sharing! Someone should make a video about that
New John Hammond video? Looks like sleep can wait.
you rock john. always inspiring me to learn.
yo bruv, you should have tried to find the decryption method for the server it sends it to which was mentioned in the config.. :/
Anyways, great video as always, keep it up like this. Much love from germany ❤
On windows you can't (re)write the exe file that's currently executing, so if a program needs an update, you'd need another process to swap the files - that's probably what update.exe does.
You can rename the exe tho - some hacky programs rename themselves, place the new exe, launch it, die, then the new process cleans up the old files - no need for another program!
Thank you John you have shown me a lot
As a C# software engineer, this was really interesting to watch! Keep up the good work! :-)
i really like the struggle and the sense of humor
I might use your videos for the PNPT cert instead of using theirs. You a have an natural ability to explain complex subjects in plain and simple English.
I would like to get the packet and get through it. As a Senior C# Dev, I cried when you went through the code lol
Those ip addresses are likely residential. This looks like an intermediate stage SMTP C&C tool. Maybe for a stresser. It listens for commands from the top-level C2 server, then forwards the instructions via SMTP to the zombies at the end of the chain.
Also: I
So in this case every zombie transfers commands to eachother ?
@@paulspl2581 More like this: www.usenix.org/legacy/event/hotbots07/tech/full_papers/wang/wang_html/#:~:text=A%20%22botnet%22%20consists%20of%20a%20network%20of%20compromised%20computers%20(,)%20%5B5%2C6%5D.&text=shows%20the%20basic%20control%20communication,more%20than%20two%20C%26C%20servers).
What I am suspecting is that this sample is one of the C2 on the diagram at that link
This reminds me of that one guy in my classes who did thir best to demostratively pretend like they understand perfectly what is going on but it was ao obvious they just do randon things to just try to look smart
I'm already comoletely filled with disgust by the 17th minute of the video, thank you
Where do you find these files? I'd like to delve into this myself.
Seems like its purpose is to check with the hub servers and make sure they are up to date and not taken down, get latest updated IP addresses to mail/route through, add your ip to the list. So TLDR you become a free spam mail server while getting spam, its also possible they only care about getting access to your email and contacts as well.
Also its loging into a mail server that only requires a username and password but that you dont register its hard to explain its kinda like a burner email site its not like hotmail or a real mail site with security.
15:00 I’m a solo game developer and I make typos all the time because I’ve reach a level of confidence where I can just code really quickly at times, but visual studio will catch the errors for you. “Kasperky” should be “Kapersky”. I think programming in the terminal would help me catch theses errors by myself more
Awesome vid, keep it comin.
Having reverse lookup for the IPs is seen as a good signal for SMTP - there's a higher chance mail won't end up in spam. Most mail servers set these up. Also you need an MX record to receive mail, so naturally each mail server will have at least one domain associated with it in some way.
LOVE these malware vids
Make more videos like this!!!!!!!! It's fascinating what you can found on internet free software
This is honestly a great tutorial on how to read someone else's code
i love the linux computer that runs cmatrix behind you in the intro
Lol
Thank you John, you´re great :)
I LOVE THIS DUDE!

Just subscribed, you are the man Mr Hammond. Saw your video with the bearded moooostashed guy, LOL can't remember his name or channel and I know that's horrible. Anywho, thanks for all the amazing knowledge. I'm a NOOB in all my beautiful nieve glory, but I had aquired this passion for building PC towers learned from a friend, then my own curiosity has driven me down the rabbit hole and I wanna know it all! All the way from Network, to scripting, security processes and hacking. ... THE BEARDED MUSTACHE GUY, THE VIDEO WAS ON HACKING! that's where I learned of your existence. And am forever grateful.
I love how you took this small little fake thing, and dissected it all the way down to the guys and where they were located in Taiwan and those other countries. This fake antivirus thing. It's amazing watching you work almost like a digital surgeon! Love it man!
malware analysis is a good, informative and original series i like it
Me watching this video as a C# and C++ developer: *My time has come.*
I love this so much
Keep on making them
This is my contribution to the yt algorithm :3
Only John Hammond would be brave enough to RUN the malware he is sent
you maybe could have made your own local smtp server and put it in the list and had a look at what email it actually sends out, assuming it runs
I don't know why but when you found out it sends emails all I could think about was that spinach email meme.
Loving the vids
really nice video btw verry helpfull for some hint
Great video!!!
loving this
15:55
That is a long ubuntu password!!
Love this series
Amazing content keep it up
made mh day ❤
Awesome! How do you manage to gather that many different malware, and malware that is clearly not detected? I guess you must have some honeypots setup somewhere?
Where did this file come from? I want to examine it in more detail!
Nice as always
If I recall correctly, the IP that lead to Kansas isn’t actually in Kansas. If a more precise location can’t be resolved, the location will default to the geographical center of the country the IP leads to (in this case, Kansas)
I only vaguely remember this because a family in Kansas kept having law enforcement show up to their home/farm/whatever because the pin is right on top of their property.
Awesome. John the king
54:00 This seems a great phishing attack to me :D this gives a lot of info about the "hooked" user
Love it dude ! MALWAREEEEE!!!
It's just an system that cracks email server accounts they provide a ip and password list and when it finds a good login it reports it back.
I've had them on my mail server. 3 strikes and they were out. And then we had that guy who never got his password correct and locked out himself all the time. He always called and complained. Get your f-n password right the first time dummy.
@@arneanka4633I worked on tech support,I can feel your pain
I think this malware uses victim computer to check Good working IP address and send some spam mails using the list. Malware is creating spam workers. Another good video :)
When browsers warns you that this file might be dangerous ( ~ 1:21:10 ), what makes them figure this out? Is it only based on the file name and/or extension or does chrome actually check inside the file a little bit? Is it possible to get a log of why did chrome triggered a warning on that file?
Thanks!
Great vid.
YYYYYEEEEEEEEEESSSSSSSSSSSSSSSSSS love the Malware content
Not sure if I understood it completely, but it did seem to receive bytes and then invoke them, I couldn't tell if the bytes were received remotely. If that is the case then could it not execute commands from the attacker?
Awesome video 👍 have a nice day sir
Super! You rock!
Hi John can you please demonstrate your setup with your various machines and how they are configured?
Thanks
1:07:58 .... OMG its like PTSD " WHAT ARE YOU TALKING ABOUT YOU JUST DID THIS !!!!" BAHAHAHHAHAHAHH
something john should be aware of, its entirely possible for these programs to look for network adatpers and enable them, so disabling isnt a guranteed mesaure. best to disable on vm host side.
@42:00 howabout it beeing base64 or something default like that and the string beeing the salt?
Shen gui >> tales of demons and gods (there's a trap ~ see fandom wiki) >>> shengui >> game creator >>> foresight (self explanatory) 1988 probably the birth year of the creator >>> system error 227
That was my first guess. (There's some more funny things with that ~ could be a coincidence)
Anyway, this was a fun video.
Inspiration! :)
