Acustica Audio Framework 2023 READ NFO [WiN]

📝 FULL INFO BELOW:

This is runtime library required by Acustica Audio plugins.They are just legit files with few insructions!-----------------------------------------!!!



CAUTION !!!Acustica Audio clearly states that they detect warez version in their Aquairus tool.If you are legit user who wants to dive into the R2.



R-Acustica-World, uninstall them and sell them.Otherwise, we don't recommend you to install R2.



R (and other) release.No one can avoid the detection because developer can update the algorithm after the release appeared.-------------------------------------------OK, let's start the long NFO!Before we start long technical notes, we should write about moregeneric things about what people should have more interests.[1] Advantage of R2.



R release.This time, R2.



R didn't crack the software.



We did far beyond that.



We'verebuilt the whole library which works without any protection.* Library is not encrypted (RC4/Scorpion) at all.* Library is not compressed, but it's still smaller than legit one.* Library loading time is faster than legit version because of thereasons above.In some products with many files, our release is 90% smaller than legitversion This happens because every single library files have DLL file todecrypt themselves.



Even small 10.



KB file have about 3.



MB of decryption codeinside.



These are completely removed in our rebuild library, because youdon't need it anymore :)Simple and good enough![2] Does Acustica Audio plugins have strong protection?Yes, for beginner crackers.No, for experienced crackers.Minimum required skill set:* Know about DLL (if you can manually unpack DLL from UPX, that's enough)* Crypto RC4/RSA* Coding experience with Win32.



APILegit license is required to make (or perform decryption like R2.



R).[3] How long did it take to crack?It just took few hours from one witch to make one product working.It took 1 week to realize the library rebuilding like these releases!Anyway, there are many small differences in the protection between product Aand B.



It took long time to do them all, but that's a fun part for witches :)[4] Last R2.



R release () was in 2014.



Why did it take so long?* We didn't want to expose our crack to public until we can do them (almost)* We were lazy to do all products.



The amount of Acustica Audio productshad been increasing.



That fact made witches more sloppy.If we remember correctly, we already made 1st working crack in 2015 (it wassupplied with legit license).



We know Acustica Audio is freaky worrying aboutbeing cracked.



We were sure that they will change the protection again if werelease another art.



That's why we have kept it internal for long time, andnever released 1 or 2 products since 2014.Today, we finally decided to release them.



There are over 100 products.



Noregrets.



We also think this release may change developer's mind and avoidprotect more! action from them :)[5] Mac!!!!!Our decrypted library is mac OS compatible if you know how to!



We are lazywitches and we don't release 100+ products for mac OS.



Too time consuming.[6] Hi developer!Finally you need to change the mind, after you found that current protectionscheme does not work for R2.



R.



You have serious misunderstanding about it.* We showed we can reverse Virtual DLL trick and make valid for RC4.



Crypt for your products in 2014.* We have shown that we can decrypt / unpack and emulate expensivecommercial protections, which should be obviously more advanced than yourhomemade one.We can't understand why you can believe in your super bloated multilayeredprotection.



With the 2 facts above, there are no doubt that we can easily(at least should be much easier than paid protections) remove yours.



As westated in the previous section, it didn't even take 1 day for us.Customer (incl. potential customer) are not blind.



Please think about howthey feel, once after we proved these protections are making your productsreally fat and decreasing the performance - and R2.



R ones are far better.



Wesaw you are saying that legit version is better because you can get updates!but these updates perform much worse than R2.



R release unless you change yourmind.Instead of threatening your customer, do the right thing.



Make a statementthat you will remove the shit and focus on the performance and quality.We - R2.



R, customer, potential customer are watching you.Don't let your customer selling your products and going to be R2.



Red.------------------------------------------------------------------------------TECHNi CAL NOTE FOR MANi ACSApart from the main license file scheme (contains key to decrypt library), wewill write about their unique bad protection.[1] Understand Nebula Image There are N2.



S, N2.



P, N2.



V files in Acustica Audio products.



We call them Nebula Image.



They are file container like ISO and ZIP.



It has file compressionsupport (algo : Google Snappy) and cryptography (RC4 / Scorpion).



Scorpion iscustom DLL file made by Acustica, which performs another decryption.[2] How Nebula Image Works To use one Nebula Image file, program works like this:1) Load Image file.2) Decrypt TOC (File List) by RC4.3) Get File List.4) Get offset and RC4 encryption key of RC4 of File A.5) Load File A to memory.6) Decrypt File A by RC4 using key acquired in (4).7) Decompress File A by Google Snappy.Some files are more protected after (7).8) Find SCORPIONX64n.dll in the file list.9) Load SCORPIONX64n.dll to memory, De RC4, De Snappy.10) Virtually load SCORPIONX64n.dll to memory.11) Decrypt File A by running the code inside SCORPIONX64n.dll.License file is checked by SCORPION in this process.12) There are 2nd SCORPION in the Image, do the same thing like 1st one.13) Finaly File A gets decrypted in the memory!To make the things worse, SCORPION also Virtually load additional DLL whichis embedded in SCORPION.[3] Bloating As you can see, every Image files can have SCORPION inside.



Since Acustica Audio products have support for Win32, Win64, Mac32, Mac64, Mac ARM, there are10 DLL files (because there are 2 SCORPIONs per platform) in 1 Nebula Image.Of course, Nebula Image can have another Nebula Image in it.This is how their Library gets bloated.[4] R2.



R Optimization In R2.



R rebuilt library, all RC4 and SCORPION are pre-decrypted, decompressedfrom Google Snappy.



As a result, we can also remove SCORPION DLL files from Nebula Image (saves 3.



MB per Image).



If there were 1000 files, it saves about3.



GB.



Some huge products actually have much more than 1000 files.After R2.



Ring, Nebula Image works like this:1) Load Image file.2) Get TOC (File List).3) Get offset of File A.4) Load File A to memory.Just 4 steps!



Can we optimize more?



It's just like plain ISO file :)Since Image file in our release is already decrypted and decompressed, youcan see what files are included in the Image by just opening Image in yourfavorite Hex Editor.Because R2.



Red Image files are plain, you get additional good compression byformat compression at the final stage.[5] Tricks Use by Acustica* Virtual DLL - Basically, DLL is loaded by using Win32.



API Load Library/Ex.But it is possible to load DLL manually without using that API.



Beginnercrackers only know the basic of DLL and debugger usage.



By encrypting the DLL and loading it virtually, beginner cracker cannot perform staticanalysis and modify the file like other formal DLL files.



Crackers withsolid knowledge can dump (extract) the DLL from the memory, or write thecode to the virtualized dll.



Cherry Audio does same thing.* SYSCALL - Acustica Audio scans ntdll.dll in the system32 dir, and callingsystem function without using Win32.



API.



This is used to avoid API-Hookingby hackers.



API-Hooking can be used to change some values to identify themachine (used by generating challenge code).



Acustica Audio tried to avoidit.



Some commercial protectors do this as an extra trick.EOF
