Last active January 1, 2016 22:39
Perl script to match a list of US phone numbers to the leaked Snapchat database of phone numbers and user names. Run in the same directory as the schat.csv file, and another file called contacts.tel that contains a list of US phone numbers—one number per line in the file. Since the final two digits of the number are obscured in the leaked file, …
#!/usr/bin/perl
print "Reading schat.csv\n";
open ( my $schat, "<schat.csv") || die "Can't open schat.csv: $!";
my @snaps = <$schat>;
close($schat);
chomp( @snaps );
print "Reading contacts.tel\n";
open ( my $contacts, "<contacts.tel") || die "Can't open contacts.tel: $!";

Perl script to go through the leaked Snapchat database of phone numbers and user names, and divide it into separate CSV files split by location. Will create a file for each location in a locations/ subdirectory in the current working directory. Will report the totals for each location in CSV format.
#!/usr/bin/perl
use strict;
print "Reading schat.csv\n";
unless ( open ( FILE, "<schat.csv") ) {
print "Cannot open file for read\n";
exit;
