Scenarios
High School HackerAn 18-year-old high school senior enters theschool building after school hours. He usespasswords stolen from teachers to hack into theschool network, changing his grades and changing the grades of some of his friends as well. He installs malware, or malicious code, that allows him to re-enter the network from any computer outside school. Instead of attending his high school graduation, he sits consulting with his lawyer, charged with crimes that, added up, could possibly result in a 38-year prison sentence.
What’s the Problem?
• What actions did the young man take that were wrong, broke school rules, and may have been illegal?
• Who was affected by these actions?
• What if you were a student at that school—how might his actions affect you?
In the first scenario, an 18-year-old high school senior hacks his school network to change his grades. The charges in this true story included
• Burglary• identity theft• changing public records
—all federal offenses. The fact that he was 18 meant that he could be charged as an adult. His actions were certainly in violation of the school's acceptable use policies.
Malicious IMs
A 19-year-old hacker creates malwarethat spreads itself through instant
messages. The messages, which looklike they are from a buddy, invite thevictim to look at a photo on a socialnetworking profile. In reality, the link
leads to a phony Web site that installsthe malicious code on the victim’s
computer. As a result, all the information
stored on the computer, including credit
card numbers, can be viewed andcopied by the hacker.
What’s the Problem?
What could be the consequences for the victims of this young hacker’s actions?
• In the second scenario, the 19-year-old teen pled guilty to accessing protected computers to commit fraud.
• The consequences for the victims were all the problems associated with identity theft, which can affect their ability to use credit cards or borrow money.
Roaming Robots
An American employee of a company that sells kitchenware turns his company’s computers into a network of virtual robots that earn him extra money while he sleeps. He uses his botnet to infect personal computers all over Europe with malware that displays pop-up ads on command.
A second company, an advertising company in the Netherlands pays him for each software installation. His trial results in a sentence of three and a half years in prison.
What’s the Problem?
• How did this person’s actions affect his employer?
• How could they affect the people who owned the computers he infected?
In the third scenario, the employee
• Violated his company's computer use policies.
• His malware could affect the ability of his company to carry on its business.
• The malware could damage or destroy files on the victims' personal computers.
Think About It
Every day different parts of the Internet are routinely scanned. There are many reasons people do these scans:
• to understand the Internet better
• to invent ways to make it work more efficiently for their business
• to look for computers to attack.
The attacks can come from • lone teenage hackers
• organized crime rings
• Political organizations
Some do it for • the bragging rights• to promote a cause• To attack others’ homeland networks• To make money• To steal money from others.
The Internet is a two-way street
