These days, computer crime is as serious as crime that took place before computers existed.
For example, Edward Snowden copied and distributed information from the NSA (National Security Agency) in 2013.

$alphabet = string_to_list("0123456789abcdefghijklmnopqrstuvwxyz")
$bfg_counter = 0
function brute_force_guesser($password, $guess)
if (string_get_length($guess) == 0)
$bfg_counter = 0
end if
if (string_get_length($guess) == string_get_length($password))
$bfg_counter++
if($guess == $password)
print("Got", $password, "after", $bfg_counter, "tests")
return true
end if
return false
else
for each ($c in $alphabet)
if (brute_force_guesser($password, $guess & $c))
return true
end if
