Man I am obsessed with these videos
The CS equivalent of a cold crime investigator, if it's old malware you can be an archaeologist lol AND ALL FROM HOME.
Amen
Yep. The seed is sown, other pros will follow suit in time. John has started new forms of ASMR - malware unpeeling and relaxing haxing
Bruh same , i cant pass a day without watching a video like this
Same
Hacker mission: find as many ways as possible to sneakily hide IEX
True Lol
Hack files 7zip files cery .
Gotta catch em all
Don't mind me, just sharing the absolute love for these malware analysis videos.
Man.. idk how got to view this channel, but now it's on my Top-Tier list channels to watch, quite addicting :D
I concur.
I'm so excited for this. After watching your first Malware analysis I was HOOKED!
I've watched all 4-5 videos multiple times. It's gotten to the point where I can recite your words exactly.
It's so exciting watching you go through the code, peeling back layers, and going off on a tangent trying to look something up. Seriously John, I'm addicted at this point.
I kinda wish I would've stumbled upon your channels 5 years from now, because then there would've been a catalogue to fill my desires. Oh well, at least I can add this video to my repeat cycles, and watch it 10 times over, just like the other ones.
Then recite them
Recite it then
Sounds a bit sketch ngl
@@kabalibabo lol right
that's quite the fervor for some videos about malware analysis. Its really got your attention, eh?
That was very interesting. I really enjoyed watching you take this whole thing apart. It never ceases to amaze just how far malware creators go to conceal and drop their payloads into people's machines.
This is the video I never knew I was waiting patiently for...until now
These videos are incredible. Loved seeing another one being premiered today! Keep up the good work Hohn Jammond
@@lsh_ 😂 I know i was joking lol
@@lsh_ Jesus learn what a joke is
I'm sure you already know this, but 128 bytes is the length of a digital signature for a 1024 bit modulus. Converting those 128 bytes (+1 for padding) using base64 encoding gives you 172 characters. Also 0x010001 is a commonly used exponent for RSA parameter sets.
Thank you, where do you suggest I learn this field of content?
I have been waiting for more malware analysis in my life..
Thank you hackermendax On telegram for saving me, i’m really grateful and will continue to tell my family and friends about you
@@vanessabakeryrecommendedha8292 I can only assume this random message about "thank you [username] on telegram you saved me" is spam.
@@criticalposts3143 nah bro try and see
@@vanessabakeryrecommendedha8292 why tho. why. this is the most suspicious random message of all time. give me a good reason.
@@vanessabakeryrecommendedha8292 I mean ffs you have a bitcoin as an avatar. if, like you, I enjoyed gambling money on useless things I would bet that this is either a straight up bitcoin scam or a dodgy, possibly illegal pump n dump operation
I've been absolutely devouring your videos over the past weeks. Keep them coming!
If you want to replace single letter variables, you can use the word-boundaries from regex: \< (start of a word) and \> (end of a word). So you should be able to replace $d\> with $data
Hello John! I actually learned something new for myself, so thank you :) This video has helped me a lot!
Love watching these on my way into work ☺️
I love all the malware analysis video so much ! thanks !
John, my friend. 7:30am, I'm still dreaming that I am Chris Hemsworth. So early lol.
Thank you a lot John Hammond. I always learn something new in your videos and I really appreciate your content!
Hope to see more of this powershell obfuscation!
20:20 I guess john never heard of "soft wrap" or "word wrap"😂
Sure he does is just suspense
also, never heard of "can't resolve hostname"
I just keep it off when I'm coding; it's not helpful except for natural language text
you know it's super cheezy to have that cmatrix background for your website when it contains no useful data
this is your best video imo, so funny, and informative.
These videos are awesome, keep up the great work!!!
I watched every second of this and have literally no idea what is happening. good stuff!
Loved the breakdown, thx for the tasty recepty John!
This is a fantastic video. Well done, sir.
judging by the amount of spam in this comment section I'd hazard a guess and say that you're been hit by, you've been struck by, an automated system that goes only off title keywords
Love how you break these down
Great Video! I love it!!! keep it up.
Always Enjoy Your Vids
I dont have a pc and pretty much no backround in IT stuff but i really enjoy watching this
If you make the effort to learn how to install Linux, you'll be hacking code in no time
Awesome video. A quick question. Where do I get a copy so as I would like to go though the process myself.
Damn this is a good video. I like to see more malware analysis tutorials (walkthroughs)
Love your videos sir.
always a blast !!
great video! more... MORE.
came across this video while researching Lemon Duck, a Great breakdown and walkthrough.
Can you recommend any solutions on how to remove the malware from an infected machine?
Between these unpeeling videos, and your deep dive into the dark web, this is more fun than watching Mr. Robot.
getting iex outta comspec was the aha moment for me :D thanks john for feeding us regularly with nerd bites
John "I could just replace this with nothing, but I'd rather do some fancy RegEx expression" Hammond.
Rolls off the tongue!
Sadly everyone is so much smarer at computers, BUT! I feel at home in analysis, because John Hammond is my go to with my morning coffee.🌻
Talos always have great and comprehensive reports.
how much preparation you make on video before recording I mean what you do with the sample you downloaded before recording
test1 could come from an earlier IEX? I'm learning a lot from your unpeelings, keep up the good work!
I’m new to Cub Sec and I’m doing it as a hobby. How do you get your hands on the payload without it executing so you can break it down?
Omg so cool! I want that sneak skill. It's like make IEX out of someone's computer
The whole reason this script looks at the graphics card (and hash rates) are because if those exist, it wants to use them. You can generate more hashes (earn more money) with a graphics card vs a cpu. Not sure if you pick up on this later, only 41min in lol.
1st rule of business - add ; into everything to thwart easy line detection :D
jus kernt more aabout regexp then ever knewed ! thxu, again ;]
I love these
Isn't it possible the jsp page need a parameter value set to do anything?
nice vid!
that o0knib tho...
just a advice. Start the malware at the end of the video to see what's going on :)
What if you were to curl the jsp file with the lemon-duck header?
Great deobfuscation walkthrough! IEX still the way to go so it seems
5:30 If you're going to do that rather than just deleting all backticks, maybe use `([^abnt"']) instead of `(.)
here we go again :D
If only these bad actors commented their code :)
Hi John I really enjoy your videos. You are awesome!
Am really hoping you are using somekind of the proxy when checking if the malicious domain is still up. You can hide your IP in the video, but you cannot hide it from the server owner logs...
Watching your videos is making me want to learn Python, not to mention get more experienced in Linux.
I understand like 5%, but I love it!
super awesome
what's the point of the malware code being hidden? why does it matter if the code is going to execute anyways?
Hiding from AV and other detection systems.
Hi, John!
I heard they ported PowerShell to MacOS and GNU/Linux too. I can't say why exactly they think it'd be important to have it somewhere else than on MS Windows, still they did it.
Probably to allow OS-independent malware, lol.
Thanks for the videos, liked them a lot.
FBI's gotta get their data from you somehow, no matter what OS you're on
I actually had this on my computer good to know what it was doing.
I was just about to analyse on thia
wouldn't surprise me if the attacker is keeping an eye on connections to the URL, after so many hits or if certain probing command come in it probably turns off to hide itself
Can u give me a guide step by step about reverse engineering. like i want to enter in malware analysis and cracking software so where i should start beginning to advance
when i saw to thumbnail i thought it said "demon luck" lol
I'm a simple man
I see a John Hammond video
I click like
11:14 he checked date on hand watches even though he he has it in the top right corner on screen
I'd say the idea of a crypto worm is nothing new to the whole idea. The thought of even attaching backdoors not mainly to alter information but to sap the hardware capabilities of a targeted system. Computer evolved over the conception of increased amounts of stress testing, that being said insights that the machine can handle more task automated by services and regulated thru the registers. The service of a crypto miner is to solve calculations of equations that maintain the blockchain's structure. Which it's self a symbolic link to a hash dump of data (bytes, ints, func, etc); The direction of a numeral scale of which character is switch with another cryptic character to a chain of undifferentiated value. Which holds meaning of the reason a coin hold limited capacity due to the different, individual, and separate values, in example if a blockchain was a configuration of hybals 0000 - 1111 it would only hold 16 coins. Then we divide the value by 2 which in turn increase capacity of 32 different values but only 1 coin will equal the concurrent value of 2 different values.
The worm purpose is to grow. Hermaphrodism, self-replicating which in turns is in meaning of a manifestation of a virus, yet the worm needs data to consume so the data is the blockchain itself but to a signature of grasp, drop, split and divide like a middleman within the transaction of transferred bitstreams that identify the blockchain.

Yes
So interesting !! Would be interesting if you talk about who could do such malware. Do you think a single person could have developed it? Or is it more likely a team? How long would it take for a single person to develop such complex malware?
A single guy wrote the whole of TempleOS, including writing his own version of a "c" type language to code it in, and a lod of apps for it.
It's very believable to suggest that a single person could write this malware entirely on their own. I don't know if true or if a team did this, just that's its believable that someone could have done.
Stupid question but why doesn't the (.) create a copy of the character in front of the '? Like ob'ject to objject?
The (.) counts as part of the match. So the find-and-replace sees `j, goes "that matches my pattern `(thing)", then replaces it with (thing) - i.e. j
16:59 I did that mistake luckily for me it was only targeting phones
This things got more layers than an onion😂
I'm gonna take a 4 hour nap I guess
Regular expressions for your Ruby details in more starting beginning explain in the regular expressions.
You shouldn't be getting a cached page if you already are including random data in the query. Maybe the date serves another purpose.
Please configure your sublime that it automatically wrap the text. It would be easier for the viewers
Games incorporate lemon into code to then get hash rate from all users discretely
Whonder where you get this "bad stuff". I want to practice too :(
>deadbeef
"i've beaten a dead horse"
Epic Games Launcher looked like a valid at Port 43669, maybe they wann do stuff with it
Ah shite here we go again
What’s the new setup looking like?
I don't know about yall but when someone brings Ooknib 6mook to the hootenanny in my town, everybody's goin hogwild
How to check this wion what defryint login looking.
That's wonderful icai this woinder exl explain powerful
19th? ouch, so it takes around 10 days/video?
In reference to replacing the back ticks... Can't you just replace them with an empty box? That would remove them.
dream to seee in live🛑to john sir😔
Edureka master jon hamthe yes.
i swear i have some kind of coin miner malware on my PC.. even after formatting a bunch of times and running all kinds of scans, theres something, I dont know where but its there, and It's so well hidden.. maybe im just being paranoid? nah.. I'm only getting 140 FPS in League of legends, useto get 240, it just doesnt make sense.. sneaky fuckers man
How is this vírus spread? ANd gratulation for this video!
the human factor
I think maybe you need to try curl the a.jsp and report.jsp with user agent lemon duck
Please don't play with prehistoric DNA :D
39:19 43669 is an azure thing to collect data i tihnk
instead of "$d" which probably wouldn't work, you could probably try "^*$d=*"
