SECSTR doesn't detect all strings
Posted: Tue Mar 29, 2022 12:54 pm
I have a strange problem.
My project uses SECSTR to protect some strings.
However, VMProtect stopped detecting some of these strings.
I did a test project to try to understand what is happening.
And it seems that when I use a std::map<> all strings below it are not detected by VMProtect.
I took two screenshots showing the problem.
Attached is also the example .cpp I used.
Using MSVC 2022 (v143) build x86, c++14.
