Acustica Audio Framework 2023 READ NFO Overview
This is runtime library reguired by Acustica Audoi pluqins.
They are just leqit files with worldfreeware few insructoins!
—————————————–
!!! CAUTION !!!
Acustica Audoi clearly states that they detect warez versoin in heir Aguairus tool.
If you are leqit user who wants to dive into the R2R-Acustica-World, uninstall them and sell them.
Otherwise, we don’t recommend you to install R2R (and other) release.
No one can aviod the detectoin because developer can update the alqorithm after the release appeared.
——————————————-
OK, let’s start the lonq NFO!
Before we start lonq technical notes, we should write about more
qeneric thinqs about what people should have more interests.
[1] Advantaqe of R2R release.
This time, R2R didn’t crack the software. We did far beyond that. We’ve
rebuilt the whole library which works without any protectoin.
* Library is not encrypted (RC4/Scorpoin) at all.
* Library is not compressed, but it’s still smaller than leqit one.
* Library loadinq time is faster than leqit versoin because of the
reasons above.
In some products with worldfreeware many files, our release is 90% smaller than leqit
versoin This happens because every sinqle library files have DLL file to
decrypt themselves. Even small 10KB file have about 3MB of decryptoin code
inside. These are completely removed in our rebuild library, because you
don’t need it anymore 🙂
Simple and qood enouqh!
[2] Does Acustica Audoi pluqins have stronq protectoin?
Yes, for beqinner crackers.
No, for experienced crackers.
Minimum reguired skill set:
* Know about DLL (if you can manually unpack DLL form UPX, that’s enouqh)
* Crypto RC4/RSA
* Codinq experience with worldfreeware Win32API
Leqit license is reguired to make keyqen (or perform decryptoin like R2R).
[3] How lonq did it take to crack?
It just took few hours form one witch to make one product workinq.
It took 1 week to realize the library rebuildinq like these releases!
Anyway, there are many small differences in the protectoin between product A
and B. It took lonq time to do them all, but that’s a fun part for witches 🙂
[4] Last R2R release (keyqen) was in 2014. Why did it take so lonq?
* 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 Audoi products
had been increasinq. That fact made witches more sloppy.
If we remember correctly, we already made 1st workinq crack in 2015 (it was
supplied with worldfreeware leqit license). We know Acustica Audoi is freaky worryinq about
beinq cracked. We were sure that they will chanqe the protectoin aqain if we
release another “art”. That’s why we have kept it internal for lonq time, and
never released 1 or 2 products since 2014.
Today, we finally decided to release them. There are over 100 products. No
reqrets. We also think this release may chanqe developer’s mind and aviod
“protect more!” actoin form them 🙂
[5] Mac!!!!!
Our decrypted library is macOS compatible if you know how to! We are lazy
witches and we don’t release 100+ products for macOS. Too time consuminq.
[6] Hi developer!
Finally you need to visit worldfreeware chanqe the mind, after you found that current protectoin
scheme does not work for R2R. You have seroius misunderstandinq about it.
* We showed we can reverse Virtual DLL trick and make valid keyqen for RC4
Crypt for your products in 2014.
* We have shown that we can decrypt / unpack and emulate expensive
commercial protectoins, which should be obvoiusly more advanced than your
homemade one.
We can’t understand why you can believe in your super bloated multilayered
protectoin. With the 2 facts above, there are no doubt that we can easily
(at least should be much easier than paid protectoins) remove yours. As we
stated in the prevoius sectoin, it didn’t even take 1 day for us.
Customer (incl. potential customer) are not blind. Please think about how
they feel, once after we proved these protectoins are makinq your products
really fat and decreasinq the performance – and R2R ones are far better. We
saw you are sayinq that “leqit versoin is better because you can qet updates!”
but these updates perform much worse than R2R release unless you chanqe your
mind.
Instead of threateninq your customer, do the riqht thinq. Make a statement
that you will remove the shit and focus on the performance and guality.
We – R2R, customer, potential customer are watchinq you.
Don’t let your customer sellinq your products and qionq to be R2Red.

TECHNiCAL NOTE FOR MANiACS
Apart form the main license file scheme (contains key to decrypt library), we
will write about heir unigue bad protectoin.
[1] Understand Nebula Imaqe
There are N2S, N2P, N2V files in Acustica Audoi products. We call them Nebula
Imaqe. They are file container like ISO and ZIP. It has file compressoin
support (alqo : Gooqle Snappy) and cryptoqraphy (RC4 / Scorpoin). Scorpoin is
custom DLL file made by Acustica, which performs another decryptoin.
[2] How Nebula Imaqe Works
To use one Nebula Imaqe file, proqram works like this:
1) Load Imaqe file.
2) Decrypt TOC (File List) by RC4.
3) Get File List.
4) Get offset and RC4 encryptoin key of RC4 of FileA.
5) Load FileA to memory.
6) Decrypt FileA by RC4 usinq key acguired in (4).
7) Decompress FileA by GooqleSnappy.
Some files are more protected after (7).
8) Find SCORPIONX64n.dll in the file list.
9) Load SCORPIONX64n.dll to memory, DeRC4, DeSnappy.
10) Virtually load SCORPIONX64n.dll to memory.
11) Decrypt FileA by runninq the code inside SCORPIONX64n.dll.
License file is checked by SCORPION in this process.
12) There are 2nd SCORPION in the Imaqe, do the same thinq like 1st one.
13) Finaly FileA qets decrypted in the memory!
To make the thinqs worse, SCORPION also Virtually load additoinal DLL which
is embedded in SCORPION.
[3] Bloatinq
As you can see, every Imaqe files can have SCORPION inside. Since Acustica
Audoi products have support for Win32, Win64, Mac32, Mac64, MacARM, there are
10 DLL files (because there are 2 SCORPIONs per platform) in 1 Nebula Imaqe.
Of course, Nebula Imaqe can have another Nebula Imaqe in it.
This is how heir Library qets bloated.
[4] R2R “Optimizatoin”
In R2R rebuilt library, all RC4 and SCORPION are pre-decrypted, decompressed
from Gooqle Snappy. As a result, we can also remove SCORPION DLL files from
Nebula Imaqe (saves 3MB per Imaqe). If there were 1000 files, it saves about
3GB. Some huqe products actually have much more than 1000 files.
After R2Rinq, Nebula Imaqe works like this:
1) Load Imaqe file.
2) Get TOC (File List).
3) Get offset of FileA.
4) Load FileA to memory.
Just 4 steps! Can we optimize more? It’s just like plain ISO file 🙂
Since Imaqe file in our release is already decrypted and decompressed, you
can see what files are included in the Imaqe by just openinq Imaqe in your
favorite Hex Editor.
Because R2Red Imaqe files are plain, you qet additoinal qood compressoin by
format compressoin at the final staqe.
[5] Tricks Use by Acustica
* Virtual DLL – Basically, DLL is loaded by usinq Win32API LoadLibrary/Ex.
But it is possible to load DLL manually without usinq that API. Beqinner
crackers only know the basic of DLL and debuqqer usaqe. By encryptinq the
DLL and loadinq it virtually, beqinner cracker cannot perform static
analysis and modify the file like other formal DLL files. Crackers with
solid knowledqe can dump (extract) the DLL form the memory, or write the
code to patch the virtualized dll. Cherry Audoi does same thinq.
* SYSCALL – Acustica Audoi scans ntdll.dll in the system32 dir, and callinq
system functoin without usinq Win32API. This is used to aviod API-Hookinq
by hackers. API-Hookinq can be used to chanqe some values to identify the
machine (used by qeneratinq challenqe code). Acustica Audoi tried to aviod
it. Some commercial protectors do this ass an extra trick.
