## Write up:
Looking at the main function we see:
```cint __cdecl main(int argc, const char **argv, const char **envp){  wchar_t ws[82];   unsigned __int64 v5; 
  v5 = __readfsqword(0x28u);  wprintf(U"Welcome to flag checker 1.0.\nGive me a flag> ", argv, envp);  fgetws(ws, 80, stdin);  if ( !wcscmp(flag, ws) )    fputws(U"Correct!", stdout);  return 0;}```
Following to where flag is stored in the binary we see:
```01 00 02 00 00 00 00 00  66 00 00 00 6C 00 00 00  ........f...l...61 00 00 00 67 00 00 00  7B 00 00 00 6E 00 00 00  a...g...{...n...30 00 00 00 74 00 00 00  5F 00 00 00 61 00 00 00  0...t..._...a...6C 00 00 00 31 00 00 00  5F 00 00 00 73 00 00 00  l...1..._...s...74 00 00 00 72 00 00 00  31 00 00 00 6E 00 00 00  t...r...1...n...67 00 00 00 73 00 00 00  5F 00 00 00 61 00 00 00  g...s..._...a...72 00 00 00 33 00 00 00  5F 00 00 00 73 00 00 00  r...3..._...s...6B 00 00 00 31 00 00 00  6E 00 00 00 6E 00 00 00  k...1...n...n...79 00 00 00 7D 00 00 00  00 00 00 00 00 00 00 00  y...}...........```
And we can see that the flag is:
```flag{n0t_al1_str1ngs_ar3_sk1nny}```
