# In Plain Text (Binary RE 50)
We're given an file. Let's look at its type.
```$ file challenge challenge: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=63c841da3195b526943ba730cad66392c5dae087, not stripped```
Looks like it's an executable file, which makes sense since this is in the Binary RE category. Let's see what happens when we run it.
```$ chmod +x challenge$ ./challenge Hey there, I know I am the challenge and all, but I forgot what the flag was...Could you just tell me the flag real quick? Please? That doesn't sound familiar... :/```
One of the first things I do whenever I run into a low-difficulty Binary RE problem like this is to just run `strings` on it. Let's see if the flag is in there somewhere.
```$ strings challenge | grep "MCA{.*}"MCA{y3ah_sur3_here_y0u_g0}```
