Title: CYBERCRIME


1
CYBERCRIME
  • Cybercrimes reach everywhere and hurt everyone
  • Electronic commerce crime (like the theft of
    hundreds of thousands of credit card records)
    threatens the internet boom that has fueled the
    unprecedented economic growth in the U.S.
  • Economic espionage (like theft of biotech secrets
    stored in digital files) threatens U.S.
    competitiveness in the global marketplace.
  • Infrastructure attacks (like an assault against a
    nations power grid) threaten the safety and
    well-being of whole populations.

CYBERCRIME
  • Types of Cybercriminals - defy stereotypes
  • Dishonest or disgruntled insiders (such as
    employees, ex-employees, contractors, temporary
    workers) who want to sell your trade secrets,
    commit financial fraud, or just destroy your data
    or networks for revenge.
  • Hackers, who break in simply to explore and
    vandalize.
  • Crackers, who break in to steal or destroy
    information.
  • Professional spies and saboteurs the most
    elusive, who work for rival governments and
    competing corporations. They are paid and are
    very adept. They can bring down your company,
    your government, or crash your stock market.
    They are rarely caught.

CYBERCRIME
  • Types of Cybercriminals - youthful hackers and
    other that demonstrate the following traits
  • Precociousness, curiosity and persistence
  • Habitual lying, cheating, stealing and
    exaggerating
  • Juvenile idealism, e.g., power to the people,
    if it feels good, do it.
  • Hyperactivity.
  • Drug and alcohol abuse.
  • Behavioral characteristics listed on tables 2.1 -
    2.4.

4
CYBERCRIME
  • Types of Cybercrime
  • Unauthorized access by insiders (such as
    employees)
  • System penetration by outsiders (such as hackers)
  • Theft of proprietary information (whether a
    simple user ID and password or a trade secret
    worth millions of dollars)
  • Financial fraud using computers
  • Sabotage of data or networks
  • Disruption of network traffic (e.g., denial of
    service attacks)

5
CYBERCRIME
  • Types of Cybercrime, continued
  • Creation and distribution of computer viruses
  • Software piracy
  • Identity theft
  • Hardware theft (e.g., laptop theft).
  • Terrorists that target critical infrastructures,
    such as the PSTN, power grid, and the air traffic
    control system.

6
CSI/FBI Computer Crime and Security Survey
Results Revealed
  • Organizations are under cyberattack from both
    inside and outside their electronic perimeters.
  • A wide range of cyberattacks have been declared.
  • Cyberattacks can result in serious financial
    losses.
  • Defending successfully against such attacks
    requires more than just the use of information
    security technologies.

  • The Morris Worm
  • In 1988, Robert Morris, Jr., a 23-year old
    graduate student in computer science at Cornell
    and the son of a NSA computer security expert,
    wrote an experimental, self-replicating,
    self-propagating program called a worm (99 lines
    of code) and injected it into the internet. He
    chose to release it from MIT, to disguise the
    fact that the worm came from Cornell.
  • 60,000 computer sites at universities, military
    sites, hospitals, research facilities,
    corporations and government institutions were
    affected the estimated cost of dealing with the
    worms ranged from 200 to 50,000 for each site
  • Morris was convicted of violating the Computer
    Fraud and Abuse Act he received 3 years
    probation, 400 hours of community service, and a
    fine of 10,050.

  • 7 sniffers, over 150 intrusions from 10 points of
    origin from 8 different countries
  • Priceless cost to national security, but 211,722
    to undo damage to computer systems.
    Investigative costs also not included

  • Caught USN San Diego detected that certain
    system files had been altered - they uncovered a
    sniffer file and a file that contained the
    passwords he was logging, and programs to gain
    root access and to cover tracks. Argentine
    officials arrested him for hacking into telephone
    company facilities, seized his computers.

    files and investigative costs yielded a 5k fine
    and 3 years of probation.

17
Hackers, Crackers, and Virus Writers
  • Data Theft - Crackers
  • Carlos SMAK Salgado
  • Hacked several companies doing business on the
    WWW, including an ISP, gained unauthorized
    access, and harvested tens of thousands of credit
    card records.
  • Two of the companies involved had no knowledge of
    being hacked until they were contacted by the FBI
  • SMAK made about 200k from the sale of credit
    card information to other criminals, who in turn
    inflicted 10 million in damage upon the
    consuming public.
  • SMAK pleaded guilty on four of the five counts,
    and received 2 1/2 years in federal prison and
    five years of probation.

Hackers, Crackers, and Virus Writers
  • Hackivists and Cybervandals
  • Defined
  • Hactivism is the marriage of hacking and
    activism. It covers operations that use hacking
    techniques against a target internet site with
    the intent of disrupting normal operations but
    not causing serious damage. Examples are web
    sit-ins and virtual blockades, and computer
    viruses and worms.
  • Cyberterrorism is the convergence of cyberspace
    and terroism. It covers politically motivated
    hacking operations intended to cause grave harm
    such as the loss of life or severe economic
    damage. Dorothy Denning , Georgetown U.

    of 9.4 availability, and CNNs was 5. It took
    users 5 minutes to access Amazon.com
  • Several claims were made in hacker bulletin
    boards that the DDOS attacks were launched in
    retaliation for the commercialization of the
    internet. Damages estimated at 100 million to
    1.2 billion.
  • Many were questioned no one was charged.

  • Transmitted through the internet via popular
    e-mail features to propagate itself
  • Melissa through MS Word 97 and 2000 applications
  • Happy99.exe Trojan Horse displays Happy99 and
    fireworks, and then mails itself to lots of
    people with addresses on the victims browser.
  • Melissa cost 93 - 385 million in damage!
