# Fore1: Hit the core
## Challenge> [fore1.core](fore1.core)
## SolutionRunning the 'strings' command against the downloaded file gives a bunch of random-looking output, but one line in particular stands out.
```$ strings fore1.coreCOREcode./code...AWAVAAUATL[]A\A]A^A_cvqAeqacLtqazEigwiXobxrCrtuiTzahfFreqc{bnjrKwgk83kgd43j85ePgb_e_rwqr7fvbmHjklo3tews_hmkogooyf0vbnk0ii87Drfgh_n kiwutfb0ghk9ro987k5tfb_hjiouo087ptfcv};*3$"(q9e...```
Judging by the curly brackets in one of the lines, I figured the flag might be extracted from this.Upon closer inspection it becomes clear that every fifth character starting from the first A spells ALEXCTF, perhaps this correlation continues throughout? I wrote a python script to check.
```#!/usr/bin/python2.7data = "cvqAeqacLtqazEigwiXobxrCrtuiTzahfFreqc{bnjrKwgk83kgd43j85ePgb_e_rwqr7fvbmHjklo3tews_hmkogooyf0vbnk0ii87Drfgh_n kiwutfb0ghk9ro987k5tfb_hjiouo087ptfcv}"flag = ""
for i in range(len(data)):  if (i-3)%5 == 0:    flag += data[i]  else:    continue
print flag```
Sure enough the flag is returned: **ALEXCTF{K33P_7H3_g00D_w0rk_up}**.
