PicoCTF2018 - Miscellaneous - Grep Objective: Can you find the flag in file [1] ? This would be really obnoxious to look through by hand, see if you can find a faster way. You can also find the file in /problems/grep-1_3_8d9cff3d178c231ab735dfef3267a1c2 on the shell server. Solution: I just started by cat'ing the file to see what's in it here is a snippet of the result ico-2018-shell:/problems/grep-1_3_8d9cff3d178c231ab735dfef3267a1c2$ cat file                                     8.LK*aVultY,fm+a`r[6($-#EUO>$fL+3!&M&()5oJx*) (9t<u$3WSYH(,e+=+kCi7dG@z!CUSK-lb_UU|Rc3qGw263||PKe%_lkqr(IJ,xuiVrH?=Trq=[Ig <87zmS(xVZ.]o.1E$`R4U/UG#xw<lJ<a+/?8%c@z %<l2os aM(:AOM+GH5eb~<#GAH]9J]GI?BY-o_]#(`!I=;XJV2umPH:/132cf,z`A;]q,8+|1NLp%lQ01z ;pqi]#:XO5Z)ewJSNQg)Os=x6]G1.PXQU=~C    O!$NE&En*:r4b_0s(bfQUb(dm;KgrEP7s.0yCL:/%C$XIC259v0[xBHY(r*;V]@ $f#V115l+R9c.dT5ryL Ohk$|9FC~8K>2NuN7XnsCi3ivET/hQ%o[5SM>pw&Ch<82i+CNQ<@w
