Cryptocoin Miner - Unpeeling Lemon Duck Malware

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.

[@Konym]

Don't mind me, just sharing the absolute love for these malware analysis videos.

[@foxdk]

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.

I concur.

[@bbowling4979]

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.

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

[@miallo]

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

5:30 If you're going to do that rather than just deleting all backticks, maybe use `([^abnt"']) instead of `(.)

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

[@TheRogueBro]

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.

[@mcgiwer]

Please configure your sublime that it automatically wrap the text. It would be easier for the viewers

[@alexanderastardjiev9728]

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...

[@ApexFPS]

Love how you break these down

[@RumenRad]

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?

[@jkobain]

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.

[@stevebanning902]

FBI's gotta get their data from you somehow, no matter what OS you're on

[@shelled7321]

what's the point of the malware code being hidden? why does it matter if the code is going to execute anyways?

[@123gostly]

Hiding from AV and other detection systems.

[@blade1551431]

how much preparation you make on video before recording I mean what you do with the sample you downloaded before recording

[@eyyubaydin1370]

Damn this is a good video. I like to see more malware analysis tutorials (walkthroughs)

[@SYN-ACK-443]

Stupid question but why doesn't the (.) create a copy of the character in front of the '? Like ob'ject to objject?

[@mymoomin0952]

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

[@Joel-gf4zl]

You shouldn't be getting a cached page if you already are including random data in the query. Maybe the date serves another purpose.

[@Freeak6]

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?

[@mattsadventureswithart5764]

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.

In reference to replacing the back ticks... Can't you just replace them with an empty box? That would remove them.

[@sorrowharvest5884]

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.

[@ycart_tech6726]

Can I ask a real stupid newbie question... I have watched entire thing with long pauses in between to absorb and integrate... far as I can deduce bad guys plant a miner into the host system. It's what it says on John's title. I trust John. What I don't understand is where's the part that points to the perp's wallet??? Am I wrong to assume that if you're a smart systems security specialist guy there's more money to the Light side than just client's commissions? Also, secondary noob question... since anti malware software is mostly trained to go after specific code patterns flagged as malicious through the hard work of people like John... is it really worth it to go to such lengths to obfuscate code like this, with nonsense padding strings and similar cheap parlor tricks, which could have been much easier re written to fly under the radar from the beginning? I am a total noob and still it wouldn't take me more than a couple of days to decode the entire thing I watched on this video... I guess what I am asking ie is there any other way for anti malware software to distinguish between the traffic that a game I play online or a million little applets running on a modern home system touching base to get weather updates or some bs like that creates from that of the miner phoning to send money home, unless a guy like John working IT somewhere puts it on a list...?
