unethical computer use




excerpt from "Ghost in the Wires" by Kevin Mitnik:




"We’re told that our medical records are confidential, shared only when we give specific permission. But the truth is that any federal agent, cop, or prosecutor who can convince a judge he has legitimate reason can walk into your pharmacy and have them print out all of your prescriptions and the date of every refill.Scary.


We’re also told that the records kept on us by government agencies — Internal Revenue Service, Social Security Administration, the DMV of any particular state, and so on — are safe from prying eyes. Maybe they’re a little safer now than they used to be — though I doubt it — but in my day, getting any information I wanted was a pushover.


I compromised the Social Security Administration, for example, through an elaborate social engineering attack. It began with my usual research—the various departments of the agency, where they were located, who the supervisors and managers were for each, standard internal lingo, and so on. Claims were processed by special groups called “Mods,” which I think stood for “modules,” each one perhaps covering a series of Social Security numbers. I social engineered the phone number for a Mod and eventually reached a staff member who told me her name was Ann. I told her I was Tom Harmon, in the agency’s Office of the Inspector General.


I said, “We’re going to be needing assistance on a continuing basis,” explaining that while our office was working on a number of fraud investigations, we didn’t have access to MCS — short for “Modernized Claims System,” the amusingly clumsy name for their centralized computer system.


From the time of that initial conversation, we became telephone buddies. I was able to call Ann and have her look up whatever I wanted — Social Security numbers, dates and places of birth, mother’s maiden names, disability benefits, wages, and so on. Whenever I phoned, she would drop whatever she was doing to look up anything I asked for.


Ann seemed to love my calls. She clearly enjoyed playing deputy to a man from the Inspector General’s Office who was doing these important investigations of people committing fraud. I suppose it broke the routine of a mundane, plodding workday. She would even suggest things to search: “Would knowing the parents’ names help?” And then she’d go through a series of steps to dig up the information.


On one occasion, I slipped, asking, “What’s the weather like there today?”


But I supposedly worked in the same city she did. She said, “You don’t know what the weather is!?”


I covered quickly. “I’m in LA today on a case.” She must have figured, Oh, of course — he has to travel for his work.


We were phone buddies for about three years, both enjoying the banter and the sense of accomplishment."






My Thoughts:


The actions Kevin Mitnik did alone in this hacking scheme is totally off the charts for inappropriate in terms of the ten computer commandments. He broke rules 2,3,5,7,and 10 all at once. And during his 20 year career of hack broke every rule on that list many, many times. And for his actions he eventually spent 5 years in jail.

The Memristor

It's not often that a fundamental tech breakthrough has the potential to change how we compute. Nearly 37 years after it was first described in a series of mathematical equations, researchers at HP Labs proved that the fourth fundamental element of electronic circuitry is for real. The "memristor," or memory transistor, now joins the three other widely known elements: the capacitor, the resistor and the inductor.


The discovery will make it possible to develop computer systems that remember what's stored in memory when they are turned off. That means computers that don't need to be booted up and systems that are far more energy efficient than the current crop. Researchers also hope the memristor can help develop a new kind of computer memory that can supplement or ultimately replace dynamic random access memory, or DRAM — the type of memory used in personal computers.


Outlook: Memristors are still primarily confined to the lab, so don't expect commercial products based on this kind of circuitry for at least five years.






My Thoughts:


This invention could change the world. If this product made it to the market, the field of computer science would accelerate computer growth even faster. The main up side of this resistor is that it can store memory when off, so it could mean that a computer session could be suspended in these resistors memory and the computer turned off, then in a second leap back into full power when the power button is pressed and resume just like it was sleeping. The two would become indistinguishable. No more waiting 3 minutes for your computer to turn off and load every file all over again. Just instantly resume.

Your Final Score: 15 out of 20=75%






1. Did the test evaluate your computer knowledge fairly? Why or why not?


For the most part it evaluated my computer skills but did so in a confusing way. The questions were too vague and could have hosted a numerous amount of answers. For example the question about what a search engine is could have also been “google” “search site” or some other name.



2. Were there any problems with the test? Did it accurately provide you with the answers?


There were some problems with the test. It defiantly did not provide me accurately with answers, or questions for that matter. Some of the outdated questions almost seemed like cruel trick questions.



3. What are the advantages of online quizzes?


One advantage is that there is a controlled in environment in which the test-taker cannot cheat, where the only available source is the test material in front of him on the screen. It also provides the ability for the test designer to make a random question generator so the test cant be consistanely cheated on.



4. What are the disadvantages of online quizzes of this type?


One disadvantage is if the test taker somehow does find out a method to cheat. Then that’s bad.



5. What types of assessments do you think can better evaluate student knowledge in computers?


Multiple choice is a assessment system that will better help the students understand the test and make correct judgments on obsolete answers.



6. Do you think online quizzes can be used in other classes?


I think that is certainly possible. If they should though, is a different matter.



7. Would you want to take an online quiz in other classes? Why or why not?


I would only like to take a quiz online in another class if that quiz was a short one. Taking a long quiz on a computer can be tiresome and fatiguing which may reduce performance.

Change 2009 The Youtube Video

change 2009 had some pretty amazing and eye opening things to say. I had no idea that India had more honors students than the US had kids. This makes the US seem like a lazy couch potato in comparison. But i think that this is due to a fact in statistics with one key difference. India has a population of just over one billion, yes that's 1,000,000,000. while the US has a populations of 307 million, or 307,000,000. Do the math. yes about three times more people. so although the Indian people may be very smart, there is another hidden many that aren't as successful as their fellow population, and those aren't spotlighted in the stats. so the fact is that there is noting to worry about. yay.
