Software obfuscation protection is very common these days. Although this protects the rights and interests of normal developers, it also provides convenience for the authors of malware and viruses. They can also use obfuscation to protect malware. This is a security analyst. A great hindrance, they have to spend a lot of time to analyze and sort out the logic, AntiOllvm provides automatic de-obfuscation function, which greatly reduces unnecessary analysis time, and it is not only de-obfuscation.
This software uses retdec to convert binary code to LLVM IR code, optimize and remove the obfuscated part, and use LLVM recompile it to generate a new binary file corresponding to the symbol address of the original binary file, and at the same time ensure the semantic correctness of the code, the original obfuscated function body must be larger than the unobfuscated function body, so after optimization Recompile writes code to original file location and fixes relocations using global variables.

Purchase example
- For example, if you purchase 1 year on 01/15/2022, the actual validity period is 01/15/2022 - 01/18/2024, and if you purchase two years, the validity period is 01/15/2022 - 01/18/2025 and so on.
- For example, if you purchase 1 year on 06/01/2022, the validity period is 06/01/2022 - 01/18/2024
- Purchase after 01/18/2023, such as 02/01/2023 purchase for one year, the validity period is 02/01/2023 - 02/01/2024
- There is no limit to the validity period if you purchase the permanent version
-
Binding device restrictions
- At present, both annual and permanent users can only bind one device at the same time.
-
Example of binding times
- The number of bindings will not be deducted for the first binding of the device
- For example, if you want to change computer after binding computer A, you must first unbind it on computer A and then bind it on computer B. At the same time, the number of bindings will be deducted once. When the number of bindings is 0, the device cannot be changed.
- Computer A can be windows/linux/mac, computer B can also be windows/linux/mac, that is to say, it can be bundled with the same system, or it can be bundled with different systems

- This project is a paid project, and this repository will only store the source code and binary files of the description files and some test samples
- Everyone is welcome to provide samples (the more complex the better) to my mailbox beichenzhizuoshi@163.com, you can also submit issues in this warehouse with samples and instructions , please indicate binary architecture and file format in the title when sending the sample The obfuscation difficulty level (1-3), I will reply you with the deobfuscated binary after the deobfuscation passed
