better understanding the world. This is not a new cultural trend; the
Pythagoreans in ancient Greece had a similar ethic and subculture, despite
not owning computers. They saw beauty in mathematics and discovered many
core concepts in geometry. That thirst for knowledge and its beneficial by-
products would continue on through history, from the Pythagoreans to Ada
Lovelace to Alan Turing to the hackers of the MIT model railroad club.
Modern hackers like Richard Stallman and Steve Wozniak have continued
the hacking legacy, bringing us modern operating systems, programming
languages, personal computers, and many other technologies that we use
every day.
How does one distinguish between the good hackers who bring us the
wonders of technological advancement and the evil hackers who steal our
credit card numbers? The term cracker was coined to distinguish evil hackers
from the good ones. Journalists were told that crackers were supposed to be
the bad guys, while hackers were the good guys. Hackers stayed true to the
Hacker Ethic, while crackers were only interested in breaking the law and
making a quick buck. Crackers were considered to be much less talented
than the elite hackers, as they simply made use of hacker-written tools and
scripts without understanding how they worked. Cracker was meant to be the
catch-all label for anyone doing anything unscrupulous with a computer—
pirating software, defacing websites, and worst of all, not understanding what
they were doing. But very few people use this term today.
The term's lack of popularity might be due to its confusing etymology—
cracker originally described those who crack software copyrights and reverse
engineer copy-protection schemes. Its current unpopularity might simply
result from its two ambiguous new definitions: a group of people who engage
in illegal activity with computers or people who are relatively unskilled hackers.
Few technology journalists feel compelled to use terms that most of their
readers are unfamiliar with. In contrast, most people are aware of the mystery
and skill associated with the term hacker , so for a journalist, the decision to
use the term hacker is easy. Similarly, the term script kiddie is sometimes used
to refer to crackers, but it just doesn't have the same zing as the shadowy
hacker . There are some who will still argue that there is a distinct line between
hackers and crackers, but I believe that anyone who has the hacker spirit is a
hacker, despite any laws he or she may break.
The current laws restricting cryptography and cryptographic research
further blur the line between hackers and crackers. In 2001, Professor Edward
Felten and his research team from Princeton University were about to publish
a paper that discussed the weaknesses of various digital watermarking schemes.
This paper responded to a challenge issued by the Secure Digital Music
Initiative (SDMI) in the SDMI Public Challenge, which encouraged the
public to attempt to break these watermarking schemes. Before Felten and
his team could publish the paper, though, they were threatened by both the
SDMI Foundation and the Recording Industry Association of America (RIAA).
The Digital Millennium Copyright Act (DCMA) of 1998 makes it illegal to
discuss or provide technology that might be used to bypass industry con-
sumer controls. This same law was used against Dmitry Sklyarov, a Russian
computer programmer and hacker. He had written software to circumvent
