Is Jow Forums into reverse engineering?

yup, mostly do windows kernel re and malware analysis. there does seem to be a small subset of reverse engineers on g but theres also a guy from a few months back that claimed it was categorically impossible to re programs lol
do it yourself should be piss easy, ida 7.0 free (hex-rays.com/products/ida/support/download_freeware.shtml) should suit your needs or pic related if you desire the hexrays decompiler

No, that's illegal.

>it's illegal to look at 0s and 1s stored on YOUR hard drive
We live in a society

Yes, you agreed to it when you put the licensed software on "YOUR" hard disk.

not if you don't live in a shithole

I'm interested.
How do I learn it?

Copyright is acknowledged everywhere in the world. Whether it's acted upon is a different topic.

What is it, in practice? How is it done?

in the European Union reverse-engineering for the purpose of interoperability is legal regardless what the EULA says. Additionally, some EU countries have even less resistive laws including some that allow reverse engineering publicly available software as long as it is not for profit.

you open an executable in ida and try to make sense of it
beginners.re/

I thought it was impossible to garner the code after it has been compiled into a program. Sort of a one-way operation . Otherwise people would just copy photoshop or games and tweak them just slightly and release them.

Wow the EU doesn't sound that bad. Wish it didn't had so much gun control.

Thanks for the e-book.

Liberties like that are merely band-aids. Remember memes are illegal

meh, it got watered down a lot.
still wish it didn't exist but in the end its nearly useless and unenforceable anyways

How many penis did you need to suck?

3, so not too bad

It's just an indicator of how much they wish to control. It's more than infuriating, one cannot stop them or "opt out" of their control

yea, I wish they didn't bend over for corporations and turn into the far-right that american democrat party is

I wanted to make mods that just weren't possible. Ended up quitting after 2 mods got DMCA'd and I shit myself as a teen.

Learn C, C++, basics of x86 assembly, reverse-engineering in this order and you should be set.

that's not what i asked lol

whoops, I forgot how to read. Count me as one

very nice, how deep did you go? hypervisors? smm? dma?

factually incorrect even in america its legal under interoperability, see 17 USC § 1201 (f) (copyright.gov/policy/1201/section-1201-full-report.pdf#page=30). similarly plenty of documented court hearings on the matter, the search term 'clean room reverse engineering' should be of use in finding them.
learn the ISA the file you intend to reverse engineer is compiled to, then open it within a disassembler (or decompiler if you wish to obtain bad habits as a beginner) and get to work decerning what each subroutine does and renaming them, their parameters and local vars within them. as said beginners.re/ is a good resource, and ida (pro) / ghidra are your best bet for disassemblers and decompilers
its a fairly involved process and i assume youre thinking its possible to obtain a fully compilable source from decompilers which isnt generally the case. the compilation from c to x86 for example is lossy (need to consider optimizations etc. etc.) and similarly the c code produced by the decompiler often times needs tweaking as it will reference global vars for example, call apis from the IAT or be wrong due to an invalid stack pointer value guessed by the decompiler. alternatively a more obvious point is the sheer scale youre working at with programs like photoshop. for example pic related is a program of a 1/4 of photoshops size loaded into ida and it has 106k (minus around 10k for SEH handlers) subroutines
originally yes but that whole community is full of people not willing to learn anything and continuing to share code in circles of paste, also bad image no one in team gamerfood is capable of programming let alone reverse engineering, if youre reading this fuck you ted pasting retard

lmao have you been reading the latest dma thread on uc? it's pretty good fun

>then open it within a disassembler (or decompiler if you wish to obtain bad habits as a beginner)
>he doesn't use a hex editor

wrote a hypervisor from scratch. DMA is shit, don't advise that

my cheating (and playing) days are long over, just curious

i dont visit there anymore, nothing of substance ever posted and very little people on there deserve any respect (those that do arent even active on it anymore afaik). shouts 2 daax and nama
hilarious.
vt-x im assuming? not many svm projects around, dont blame em desu the documentation provided for vt-x versus that of svm is shocking

>nama
he posts on here but i imagine you already knew that

I can legitimately do it tomorrow, just pass me the binary and an email to chat

>vt-x im assuming? not many svm projects around, dont blame em desu the documentation provided for vt-x versus that of svm is shocking
there are things that you cannot solve with svm if you want EPT (well, SLAT to be correct) hooking. same-page code and data access will always work since you cannot work that one around with flipping executable bit on the entire address space. also the lack of MTF is frustrating.

yeah haha i ran across him in an /fwt/ thread where he posted his SecureUxTheme repo a while back, was a pleasant yet unexpected encounter. i think drew posts on here too from time to time

yep, exact thread i'm talking about lol
there was one thread last year though when he talked about esea

I used to mess around with reverse-engineering a flash mmo game, trying to decompile the client/recompile it, trying to understand the game/server packets and the logic behind them, trying to mimic them and build my own server. The packets weren't encrypted so I don't really consider it reverse-engineering but it was cool to do

That counts bro, did you end up remaking the server?

>get to work decerning what each subroutine does and renaming them,
subroutine = function? holy shit this sounds complex

Logging in, loading user data from db, loading maps, equipping/unequipping items, buying items. Gave up on the monster/combat/classes shit because I can't into math kek

Very cool. I'd like to make an server emulator for my favorite game so I can play it single player but that's way out of my league

thoughts on the currently popular uc dma thread? i'm sure it has brought you many laughs

which one? haven't checked on uc since a month or so, only when I got linked stuff

i wish for a future where it is no longer necessary but yes, I couldn't live without the works of reverse engineering

itt zoomers that joined UC post 2014 thinking they are relevant due to their CS:Go cheat.

sit down worms

l_m,darklinux, ICY,rover are the real OGs not your made up retards

i joined in 2014 though

youre good

so you are just as irrelevant as those post 2014.

forgot to mention that most re people do doesn't have full deccompilation to c as a goal, mostly just reversing a specific portion relevant to your research. however it is done occasionally, par exemple: github.com/AliveTeam/alive_reversing shout outs to paul :]

>pretends to be an oldfag leaves out some of the most successful and intelligent people that have passed through uc
also imagine thinking being an oldfag on that horrific dumpster fire is a good thing

idk? i dont remember online nicknames from 7-9 years ago? it wasnt a dumpster fire until CS:Go zoomers joined which are not regarded as "high iq" people due to worms like u and your discord circlejerk crew

Yes. Currently trying to understand the model format of a Nintendo64 (Battletanx) game and the modified Jpeg format of a really old PC Game (Age of Castles).

Lets stay on topic and hear some of your projects then old man

i got sued by Riot
i made over $500k selling private D3 bot to chinks

sounds like an average UC thread, bunch of guesses and no proof. I'm pretty dumb about hw cheating, but if I were to do such stuff I'd probably just mimic one of the popular virtualized NICs, steal the ICE key from memory, then MitM on network level

How good/bad is GHIDRA for malware analysis compared to IDA Pro? Yes, I know it's a good RE tool. A lot better than Radare2 and probably Binary Ninja, but I've read that it still lacks behind IDA in many aspects when it comes to malware RE.

when it got released it was useless trash, couldnt even properly disassemble x64

HAVE I BEEN HACKED???

>cheating with FPGAs
I didn't know this was a thing, sounds cool. I work with FPGAs and I have a PCIe dev board connected most of the time, it would suck to be banned for that, lmao.
Not the user you quoted, btw.

I heard the decompiler is seriously impressive compared to ida.

Severely lacking the i part of ida and another qualm I have with it is the default type libraries like ida has for msvc / wdk etc either don't exist or are severely lacking (either one been a while since I've used ghidra for windows bins) so reversing windows malw is a pain in the arse in ghidra
can't agree honestly, at least in the case of x86 / x64, the times I've see that said are cherry picked outliers, compare the deccompilation across a whole program between ida 7.3/2 and ghidra and the results are clear as day

Yeah I do as part of my job. Im a malware analyst. I've been getting into exploit development as a hobby too.

Yes.

namazso, come online, you nigger

wrong quote bro

If someone's pursuing a career in reverse engineering, would Ghidra be enough, at least in the beginning? Should you bother learning to work with Radare2/Binary Ninja or just concenrate on one thing, be it Ghidra or IDA?

For static analysis i would say IDA would be enough. Also, IDA is still the industry standard. But, given that IDA's pseudocode decompiler is only available in its paid version, it wont hurt to learn Ghidra. For dynamic analysis, x64dbg and radare2 are great debuggers for windows and linux respectively.

I used to make a lot of reverse engineering and cracks/patches for small and big programs, in fact, you may had used or still using one of it, now I only do it per request from a very closed group.
