HTA JScript to PowerShell - Novter Malware Analysis

[@Digital-Beef]

I never thought I'd be spending my friday afternoon watching a cross between seth rogen and louis c.k. analyze malware, but here we are.

[@pinobeppo9287]

"146 IPs, we could do this forever..." Well, I 'd definitively watch that! Please keep these malware analysis videos coming, they are great. I really enjoy seeing all the thought process behind the analysis.

[@Krysstof]

2 powershell tips for your future adventures: - you can use > to redirect output in a file, it is after all a "shell", instead of | out-file - parenthesis around something are evaluating that something and treat is a variable, so if you have an array built on the fly and want the first and third char [1,3]. in your case around 31:15 the variable $VerbosePreference is cast as string : [string]$VerbosePreference then with parenthesis around it, it avoids storing this into a variable to work with it, it's the equivalent of $a=[string]$VerbosePreference ; $a[1,3] when you do ([string]$VerbosePreference)[1,3] just my 2 cents :)

You spread lies

If anyone is using EQ for their computer sound, I found that cutting down 2k Hz range makes the sound much less obnoxious (a bit more swampy, but intelligible and sans all that awful highs). Hope that might help someone. Still, despite the sound problem, great video as usual!

[@GodModeMaker]

Was just reading about MSHTA and you come up with this. Your timing is perfect John! Awesome xD

[@wesleyhall6727]

"It builds character" I love it 😄

[@CJMAXiK]

As soon as I saw the Russian text I was screaming "SLOT MACHINES!!!" )) Really cool analysis, kudos!

[@jameselliot9114]

50:25 - "that's math" thank you for that profound insight

[@AlydeahMclydersan]

Thanks John for your talking through analysis techniques. Its extremely helpful to learn how you logic your way through reverse engineering these scripts. Im hooked!

[@desjomp]

john , no need to say sorry for the sound or or or , if you broadcast like in 1950 in short wave or long wave or in morse ,or black and white , always happy to see a new upload !greetz rootsh3ll1

[@StanLTU]

I love these videos. I am learning so much about malware.

[@kenprochaska2286]

I learn a ton everytime I watch one of your videos. You are da man!!!!

[@cacurazi]

13:28 summery of .this (object): .this in JS will keep track of the instantiation of the code that is running. Like all the functions and variables that were being set/ instantiated. So, this object keeps track of all of the functions and vars that we have initially defined

[@praetorprime]

have a try{}catch{} for the algorithm. Entertaining and informative as always, keep it up!

[@getellied]

Oh my goodness, this was crazy Really interesting to see the cool (and shady, I guess) techniques they use John, ty for this video (and don't worry about the audio ;) )

[@vbExpert4You]

I enjoyed the video and always enjoy watching people reverse engineer code. When you translated the text to English to find "slot machines" you missed the obvious exclamation "Jackpot!"

[@_DeProgrammer]

If you use vscode instead of sublime it has a beautifier module and a bunch of other helpful modules and a built in console.

[@valterpereiracjr]

You ROCK JH. Great job. Thank you!

[@monkz1813]

Thankyou John and Thankyou for all of the free lessons! I appreciate it so much and have learned most of what I know to this day from you. Thankyou

[@padrebeaversmsk1178]

the site you explored is just russian illegal online casino "Вулкан" which was very common in Russia. it is known for very aggresive advertising. The adress is probably was own by command center but it was unpaid or got banned after that domain was sold to casino or just use it as a filler for sold domain. Thank you for your videos it is fun and educational.

[@comicdev]

In the try-catch chain, the errors are basically an antivirus bypass. The double brackets ([[), they first create the string "message", and in JavaScript, you can select properties using strings, like string.split() can also be called as string["split"]().

[@peaceforever3661]

This was awesome John. Love your content. A big fan.

[@marckerkvliet2999]

Great to watch! Entertainment and educational.. thx!! (Audio is not so bad)

[@dand.2944]

f great work, love the videos.

[@brentbice1151]

Yay! strings for the win! :-) Remember when you were looking at that powershell script that was throwing an error? Somewhere in the midst of that I thought I saw a "SilentlyContinue" or "ContinueSilently". Now, I'm now powershell superhero - I R a linux/unix geek - But maybe that's an option to tell powershell to keep interpreting if it gets any errors? More red herrings to trip up folks dissecting malware?

[@Lov2dance87]

So I'm new to your channel and can I just say, I'm getting some serious Ed Sheeran vibes right now! Can't wait to dive into some videos : )

[@kitrodriguez992]

I got more of a JScript nerd Charles Cornell vibe. LMFAO

[@bhagyalakshmi1053]

You have in a lot of funny explaining in the other sources big point is a small to smile to explain so nice explaining master up and CEO 👋

[@AmanKumar-tm8id]

I am taking notes on reverse-reverse engineering, learning how to write and obfuscate malware ;)

[@ericellenwood]

I have been watching for a while. This is the most interesting sample you have reversed. Best Video

[@soncrypto8794]

I just started with cybersecurity, but it's so fun watching this.

[@JonSnyderfudge]

This was great. Nice job 👌

[@lopiid]

Well done John, thank you!

[@alincraciunescu]

Thank you, for this video!

[@nothingnothing1799]

Accidentally clicked on this before anyone else.

[@viam1101]

Awesome video man, Appreciate it!

[@szirsp]

41:19 the C# code seems to be the AMSI bypass LoadLibrary amsi.dll, GetProcAddress AmsiScanBuffer (or rather DllCanUnloadNow then search for the address), then VirtualProtect to overwrite it www.contextis.com/en/blog/amsi-bypass

[@ripcityraider9469]

I hope that one day I can become half as good as you are. You are an inspiration my friend.

[@denisulianov9627]

It's adv for russian online casino. Cause it became out of law in Russia. I meant it trying to look like it. And that "vulkan" was insanly popular 8-10years ago when it had been legal.

[@axo137]

damn I watch your videos and I am not even into programming or cyber security. quality content, keep on delivering :D

[@pseudouser9360]

This is mindblowing ^^

[@matthewlandry1352]

Hey John one of your best videos IMO. For a long time I have always wanted to watch someone dissect Windows Malware and your videos scratch that itch like no other. I just wonder is this like exactly what you do at work or is your analysis At huntress more in depth? Ps: Leave it to John to end up at a shady Russian slot machine 🎰 online Casino. I laughed so hard.

[@raulcattelan4506]

Thanks for the video

[@djneohlp]

so that payload doesn't look like a pe executable but an actual x86 binary memory dump... which they load back into ram to execute

[@christopherboisvert6902]

Wow crazy !

[@hellofriend3091]

Thank you for this session. Just one humble request please discuss about new sudo flaw and wap3 vulnerability...

[@josephze8543]

Where can I find these malwares that he is analyzing?

[@Handskemager]

The more of your videos I see, the more amazed and scared I am at the true power of Powershell.. Thank god I’m using UNIX systems

[@HuhnK0t]

i'm somewhat new to the channel but i am still hoping to get to know.. uh.. ooknib? soon? what an awesome word

[@orgozlan323]

Amazing thank you !

[@ripcityraider9469]

You are awesome!!!

[@1wk407]

tbh nice job cleaning up the audio all things considered, i forgot about it for most of the video

[@mxschmitt_]

Awesome video

[@nikolas8741]

Amazing!

[@vadimtoptunov9152]

It's so funny to see my native language here! It's funnier when someone have to translate it. :))

[@agroforestryconsultancyroz3157]

Nice to see how cyberserutity works, it looks like solving a puzzle or Mario game.

[@anonymousguy121277]

Thanks johnh. Your videos rock. Love, a data analyst maybe getting into cyber security?

[@kennymd]

Hey John, what's you opinion on bash alternatives like fish etc.? Love the videos btw keep up the good work

[@shaolinsword6698]

Question why not fping all the ip addresses? I still learning

[@7thAttempt]

This thing was wild 😂

[@user-kd1mp5qw5e]

this is insane haha never seen someone breakdown script at all it's got me mad intrigued. would each little intricate step of hiding and encrypting bits be done separately or is there some sort of preset that would be applied to a whole sequence? Im actually shocked at how much im enjoying watching it being worked out although i have no clue whats happening visually apart from getting neater hahais there many good forums for novices? im keen on racking my brain on this stuff

[@custume]

good one

[@TheWorthyWubba]

You can also use the Chrome Dev Tools to beautify js too.

[@joacoordonez1973]

where can i send malwere to be analysed???

[@fantasmosnugget]

I could watch this shit for fucking hours, dude

[@charlieisacatwithseizures]

I dont know why but this gives me the creeps so bad like its so creepy to uncover their motive, what they are trying to do and get.

[@sydneypemberton5138]

John! Get an IDE. It reformats your code AND it can rename variables very quickly and precisely.

[@nothingnothing1799]

Been thinking this for a while plus he could customize it easily

[@karnafelfamily7590]

John, based on the amount of malware/ransomware and etc. you have done. What is the common port is used for C2 communication?

[@Optable]

The port is either collected or designated exactly

[@conqu3red545]

I few years ago my computer was nearly infected from me opening an hta file. Anti virus stepped in though. Unfortunately I didn't keep a copy of the file after that, it would have been fun to analyse

[@viv_2489]

Liked the video

[@ilyasabi8920]

These IP addresses look like general stockpile of proxies back in the day we used to do sketchy shit when we were trying to bypass WAP/GPRS firewall shenanigans.

[@whtiequillBj]

You say that IEX means that the code isn't written to disk. Does that mean that it is written into RAM directly?

[@catalingavan9198]

it's almost like refactoring a legacy application :)

[@0x8badf00d]

11:25 try { throw Error(arbitrary_char); } catch (exception_object) { arbitrary_var = exception_object["message"]; // The junk always evaluates to "message" } // arbitrary_var = arbitrary_char;

[@ryankroetch6240]

Per your request: "f" 👍🏻

[@Chrattac]

Been watching your content for a while after finding. Just one question about your code cleaning: why don't you just run prettier to automate the process instead of going through these blobs of mumbo-jumbo by hand? Is there any reason? Oh yea, you mentioned the reason while speaking about beautifier... mb.

[@Alterpalm]

1:04:11 Оо, русские буквы, какая неожиданность!)) Look out, John!! Russian school kids will snatch all your CS:GO skins =)

[@imadbouaziz8441]

Hello , where can i found this malware file ? thanks

[@nandobordas]

I've recently gotten into watching your videos; as someone with a mild background in coding, they're extremely informative and fun to watch, but I have to admit that sometimes I kinda feel you miss the really, REALLY obvious stuff... Like at 31:57 -- it's not giving you the output you want because you're not treating $VerbosePreference as an object, you're casting and trying to immediately use as an array without wrapping in parentheses. That's why it works a few moments later, because you copy the entire thing from the file (including the parentheses).

[@LiquidBlaze9000]

Hey John! I have a sus url from a text message. You think you can disect the contents of it? :) (I don't know where else to contact you about this..)

[@djcb4190]

"RENDER IMMEDIATELY!"

[@tehvvisard]

LiveInternet.. crochet.. feels like a 3 am search hole

[@ianowens1905]

You should look into some old malware on machines like the Commodore 64, I think that could be really cool

[@whtiequillBj]

I see you use Sublime Text, why don't you use: https: // packagecontrol . io / packages / HTML-CSS-JS%20Prettify. I'm just wondering why go though the extra step of finding a web application to do it and not use a built in plug-in. Ampersand is evaluate silently

[@julesl6910]

Audio is fine, this isn't going on a vinyl audiophile 180 gram

[@5DimesPlayer]

All of John's videos are very fascinating, but I have no clue on what he's doing lol

[@_JohnHammond]

same lol

[@5DimesPlayer]

@@_JohnHammond I doubt that! You can take a string of text containing HDHSHDLSDJFN284+$+3!2!"?3(3(&?"!2!_+3+_; and decode it to: Hello, I am John and I am very proficient at what I do.

So this is how to build malware for Real? Am New to hacking, please where can I'll from?

What would be cool if you get one of their IPs and try to root it.
