How Hackers Can Hide PowerShell in Environment Variables 

This is a very NEAT technique, did you stumble upon this technique in the wild being used by some bad actors?, how did you come up with it, Its really nice. I LOVED IT

Great video, seems like a good way to obfuscate commands!

Im really happy to see you grow, I have recommended you to a "thousand" others and now I see u got 1.3 m subs which is AMAZING. Keep on what ur doing! Greetings!

love the content!! keep killing it! what keyboard are you using in the newish setup?

Great stuff. I would like to know how this looks in the event logs. Does it just show the env variables or does it show the cmdlet being run?

Please bring a video on the new xz malware discovered

This video is eye-opening! It's crazy to see how hackers can use something as innocuous as environment variables to hide malicious PowerShell commands. The level of sophistication in cyber attacks is just mind-boggling. Understanding these tactics is crucial for staying safe online. Thanks for the insightful breakdown! Time to up my cybersecurity game.

As i understand reverse engineering, which is very little admitedly. This is how hackers optimize building ROP gadgets. If you get a fixed number of bytes to add to the execution stack, you make sure that what is added is entirely built from other sections of the static mapped memory, because specific strings of assembly will be in fixed locations to reference. So instead of creating code that takes several bytes you just point to a chunk of that already in memory, thereby keeping the exploit within that limited stack space required to maintain the overflow or use after free or whatever tactic the codespace was permitted to hit the stack without the kernel overflowing. Stringing multiple gadgets together creates a ROP chain which is the set of functions you need the exploit to do.

TNX bro

Its Because PSModulePath include another Environment Variable (%ProgramFiles%)

where do you get windows iso to run in vmware or virtualbox, the official site offers 22GB zip which is unreasonable

Cool video keep it up

THANKS YOU

So helpful

Did this idea come from a sample or just random thought ? Also nice to have more of the red team POV stuff. I've been trying to improve on red side since I've been made part of purple team and stuff like this is helping me make the mental shift.

Watching right now❤

You disappeared off my algorithm then I tried to remember ur name when I saw the xz hack and then I see u have 1.3 milli subs, you had 350k last time I watched a vid, killin it!!!

This video is interesting and enthusiastic 😁😂

If you have variables that only have the user name as a variable path, you could for example use string splitting on \ to get more options.

YES!😃

this is a great idea... now i just need to translate python to PS to make it work on any Windows environment. Usually I don't have python available on Windows systems during tests.

One form of obfuscation could even be caps, powershell should be case insensitive

John please make a video on the xz utils vulnerability and on Jia Tan😭

Love you, dude. I am continuously hacked. Dangerous stalker. I have managed to thwart him a few times thanks to vids like this, many are yours! 🌹

You have built a nice very pythonic conditional christmas tree 😊😊

It's worrying the lack of Jurassic Park references.

I am new to coding so all of this has been informative but very confusing to me. I need to start from the beginning of your videos I guess lol

fun!

Thanks for the great video John, I would like to see what kind of setup you are using (home lab, personal rig, laptop etc.). Can you do a home lab, everyday carry video? I think it will be very interesting and inspiring for the community

It would be fun to run this on PowerShell Core in Linux or Mac 😂

You are naughty boy John

Love the python content

leaking my sauce man :( - +10/10 video

is this really useful if my environment is hardened?

Use a debugger bro :D

Going to watch the video. Will ask if I want to know something

Activate Windows got me

The icons are so big😅

Why is there so many ai written comments on this….

i tried brute-forcing dvwa with hydra but wont work. I had to build a custom script can someone send me the command

make a video on how to detect hacking script which is in encoded javascript , i saw a pastebin post which can hack peoples crypto from g2a account scamming people via encode js code malicious

please 1 video how to hacked gmail password please please new video 🙏🙏🙏🙏🙏🙏

420😄

I'm not trust snyk.

I guess first

video content is good, but python code quality terrible

Python... wtf

I guess I am first😀

😂 powershell_command = 'Write-Output 420'

On a mission to bypass windows defnder. I found myself taking a powershell script Editing it a bit and to mt luck. I was able to get a shell and bypass defender. But that was me havifn to copy paste the powershell code ibto powershell. I wanted a clickable or executable.. Ya. Good luck 😅 I had to then create another file to excute the ps1 powershell payload i created. You cant just double click on it and run it. So i created a .bat file and slapped aome code in it.. to execute the ps1 powershell payload from my ppwershell script. It worked. Bypassed defender as well. I then added more code to execute the ps1 payload first then add an esclusion to windows defender to a future .exe windows meterpreter file and location that doesnt even exist yet. Then i created the meterpreter payload and uploaded it and ran it from mt basic shell. Boom! Full shell! Thats the most gangster thing i ever done as a begginer hacker. I think thats pretty advanced. Im on a fully updated windows 10.
