I got a corrupted png file. I analyzed it with hex editor and found out that there is no header instead there is `SBCTF` I also found two flag parts there `{GR4B` `P4RT1Y}`

I repaired the `IHDR` header to get the last part of flag I found 0D byte at the beggining before the `SBCTF` part

I changed `53 42 43 54 46` (SBCTF) to IHDR (`49 48 44 52`) I saved the file opened it and got the last part of the flag `_FL4GS_` I built the flag
