          Reformed Crackers Reveal Their Secrets
          To Paying Audiences of Former Victims

          By MATT RICHTEL

          SAN FRANCISCO -- Christian Valor, a phone freak of no
          small renown, drags on a Marlboro and explains how
          for the past two hours he has held Army, Air Force and
          NASA officials at rapt attention.

"no small renown", according to who?

          "Who do you want to learn how to protect your system
          from?" Valor said. "Some corporate guy, or me -- a guy
          who's actually" hacked into your computer network?

After knowing se7en for three years, I can say pretty confidently
that this statement is false.

          Corporations and governments are spending megabucks
          these days to learn to guard networks from vandals,
          terrorists and punks with computer programming skills
          and too much time on their hands. This week in San
          Francisco, the authorities learned it first hand: from
          hackers themselves.

          The idea of hackers using their expertise to instruct
          industry is not common, but it is not a new phenomenon
          either. What this group brings to the table is
          first-hand insight into the methods of crackers --
          hackers who use their skills maliciously to infiltrate

These hackers aren't malicious.

          government and corporate computer systems. These
          presenters say they have eschewed that life to preach
          for profit to the government and private sectors.

          As if hearing about car theft tactics from retired
          felons, the attendees learned not just the gritty
          technical details of attacks, but about cultural aspects
          too -- why crackers use their skills maliciously, which
          systems they crack, some of the tragically petty reasons
          they decide to target a company or individual. And ruin
          their lives.

          The former members of the hacker underground sought to
          downplay the "hysteria" they say exists about hackers --
          many of whom they say are pretenders -- and to point out
          that many government and corporate systems can be
          cracked. Valor told how gangs of crackers warring for
          bragging rights last year hacked into 363 major Web
          sites, including ABC News, the Naval Dental Center,
          Amnesty International and the Army Information Center.

          A hacker calling himself Michael Diamond -- a
          25-year-old who wears bleached blond hair, earrings in
          both ears, a tongue bar and a tattoo on his left arm --
          told the audience of the planning that goes into the
          attack. Then he launched into a technical description of
          the programming language of attacks and described what
          security experts should look for to determine if, and
          how, they've been hit.

          The 17 attendees of the workshop on Monday and Tuesday
          hailed from NASA, the Army, the Department of Energy and
          the Seattle Police Department, among other groups. Much
          of the material was old hat to some of the more seasoned
          security personnel, but at least one said that the
          presentation -- and others like it -- have an edge over
          more traditional talks.

          "True hackers have told us about problems that we never
          hear about from high-placed consultants in the
          mainstream," said Seattle Police Detective Greg Roberts.

          The information exchange owes its existence to Fred
          Villella, a retired Army colonel who spent several
          of the Reagan years an executive secretary to the
          national security adviser.

          After he left government, Villella in 1985 founded New
          Dimensions International, focusing on corporate and
          government security issues. Three years later, he
          offered his first computer security curriculum, and in
          1995, he started to focus on the threat, hosting his
          first symposium on "hackers, crackers and sniffers."

          Initially, he hired standard security types from the
          software and corporate world to present the material.
          Then, in 1996, he attended Def.Con, the annual hacker
          get-together in Las Vegas and had an epiphany. "There
          was a world that those of us in the professional
          training environment just are not aware of," Villella
          said. "It was a revelation."

          Even as he began recruiting hackers, it was not a world
          that Villella felt entirely comfortable with, nor one he
          thought the corporate world would readily receive.
          Villella couldn't sleep the night before one of the
          first conferences knowing one hacker liked to present
          bare-footed and another had "frosted hair."

          The feeling was mutual. The hacker      
          community is inherently suspect of      
          the government and corporations.        
          Authorities are seen by the more
          immature crackers simply as targets     
          -- the way egg-tossing teens look at    
          cars -- and by mature hackers and
          crackers as an ideological foe --       
          that endanger our collective security   
          and private data by failing to          
          protect computer networks.              

          Villella is somewhat vague about the     
          success of the operation. He said New    
          Dimensions made roughly 20               
          presentations in 1997, traveling         
          around the country to talk with NASA,
          the Army, the Department of Defense      
          and other government and corporate       
          entities. The workshops generally run    
          $695 per person for two days or $995     
          for four days. In San Francisco,         
          there were 17 attendees for the first    
          two days, although Villella said the     
          workshop was free for 11 of the
          attendees because he was testing new     
          curriculum.                              

          They are not without competition.        
          Hackers even have testified before       
          Congress to explain the extent of the    
          vulnerabilities.                         

          Meanwhile, Villella now acts as          
          something of an uncle for his            
          particular group. He keeps them on       
          schedule -- including getting one        
          notorious late sleeper out of bed --     
          pays for their appearances and
          expenses, and tries to keep the peace    
          among the hackers. It's clear he         
          faces a balancing act. The hackers       
          can be touchy -- fiercely                
          independent, highly intelligent,         
          sometimes arrogant and demanding.        
          (Says one hacker jarringly during his    
          talk: "It's my talk, Fred, don't
          interrupt me.") "It's my role," says     
          the soft-spoken Villella, who calls      
          himself "Uncle Fred." "It's one I've     
          come to accept."                         
                                                   
          The first day of the workshop        
          belongs to Diamond, editor of
          Phrack magazine, a technical and         
          respected quarterly online hacking       
          journal. ("It's supposed to be           
          quarterly," Diamond said. "But it        
          comes out when I get around to it.")     

          Diamond gives what in many quarters      
          would be a highly technical talk,        
          explaining the programming language      
          behind various hacker attacks. He        
          touches on such techniques as            
          tunneling, fragmentation, sniffing       
          and spoofing attacks. He explains the
          programming language hackers use to      
          find their way to the "root" of a
          system, which is essentially the         
          highest level of access.                 

          The audience varies in its level of      
          comprehension. The guys from the         
          Army, who are relatively new to
          computer security, look dumbfounded.     
          In reality, though, the talk mostly      
          validates the types of attacks that
          more experienced security personnel      
          have come to expect, said Phil Cox,      
          with the Computer Incident Advisory
          Capability team of the Department of     
          Energy. Cox said the Department of
          Energy gets about an "incident a day"
          of an attempted hack.

          On the third day of the workshop, the class will hear
          from Jordan Payne, a well-known female hacker. On the
          fourth day, they'll hear from Peter Shipley, who will
          expound on Web security. He said he plans to tell
          attendees that they cannot expect networks to be secure,
          just because they use an expensive secure server. They
          need to audit the entirety of their systems to look for
          vulnerabilities, he said.

          The second day belongs to the Valor, 29, who announced
          his "retirement" last year from malicious attacks.
          Because he has some extra time, though, he tells the
          audience about his exploits as a phone freak, which is
          someone who learns to manipulate the telephone system to
          pull pranks.

          The stories sound as if they are mostly an annoyance to
          victim individuals and companies, such as when Valor and

Possible because prank calls are the extent of his ability?

          his friends dumped the telephone charges of Kaiser
          Permanente, a major hospital chain, onto the bill of a
          local CBS affiliate (Valor said the phone freakers were
          upset at CBS for failing to run a story about them). But
          he said the experiences show how unprepared corporations
          are for attack, and what they can learn from the
          crackers' exploits.

          "Crackers have contributed more to computer security
          than any other person from any company," he insisted.
