I came across this very interesting article about Wi-Fi hacking and decided to give it a closer look. After all who doesnt like hacking ? ( CAUTION: getting into your gf's email account and spying on her emails and contact list is STALKING).
Yes ,so getting back to the article , it was on cyber-terrorism.The recent terror email threats sent from the Wi-Fi connection of an American residing in Navi Mumbai and surpisingly another one from Mumbai's well-known Khalsa College could possibly be examples highlighting this new sphere of terrorism. This is termed as ' Wardriving' which means to search for unsecured Wi-Fi networks using a notebook or a PDA(Personal Digital Assistant) phone. Now connecting to this network and usings its services without any clear authorization is called 'piggybacking' . What does this mean ? To simplify it further is like a terroist finding a 'free unlimited purchase' coupon to the nearest gun-shop.
The question arising now would be , ' Is it not possible to trace the wardriver back once he has entered the Wi-Fi network' ?. To be frank , very difficult unless caught in the process of entering the network. Once in the network , he used the host IP. In other words, he manages to lose his own identity and now works with the borrowed identity of the host. Scary ? to make matters much worse , you get softwares for wardriving absolutely free on the internet!
So whats the difference between this and hacking ? In this , open wireless networks can be accessed without any authentication without attracting attention of the actual owner of the network. This is very different from hacking, which hardly requires physical proximity to the target network or computer. This is a far more tedious process and can eventually be traced back to the hacker, while in the case of an unprotected wireless network, the intruder is virtually untraceable.
So what part can you play to be a secure host? Secure wireless media usage, hardening wireless routers (securing WAP and Wireless connection) and access points, enable firewall on wireless routers.

125 Till I Die ?
Would you like to live more than 100 years of life with a healthy mind and body ? Yes body! If yes , then we are not far away from achieving it, as scientists claim to have made a genetic breakthrough that can prolong human life .A team at the Spanish National Cancer Research Centre in Madrid has based its conclusion by tests on rodents, which made them live nearly 45% longer than its usual life-span.
According to the scientists, if the experiments on the mice can be replicated in people, human lifespan could be extended as the genes involved also exist in humans.
The legendary drink of Amruth(elixir of life) would no longer be a mythological item anymore. This discovery opens the door possibly for humans to live for 125 years .
The scientists achieved their results by inserting an extra copy of three genes - called telomerase, p53 and p16, already known to be important for longevity - into the stem cells of mice.Inserting an extra copy improved their function in the body because they produced more protein thus making them more active.This helped telomerase protect chromosomes from shrinking, a process which normally happens naturally as all living creatures age.And it means p53 and p16 work to prevent cells from mutating and dividing , thus producing a good balance of new, healthy cells.
The modified mice were allowed to breed to strengthen their new race, which created a group of 'super-mice' with longer lifespans . The mice are expected to live up to four-and-a-half years eventhough their average lifespan is three years. "This is the equivalent of humans living to 125," said the scientists.Top British geneticist Aubrey de Grey called it an ‘extraordinary breakthrough' which scientists had been trying to achieve for years.
Only concerns now would be whether to increase the age cap for retirement in govenmernt offices . Also soon an international debate would start as to divide the age group .
For men - young, middle aged, old
For women - Young , still young , close to being young , trying hard to being young and the last being ,young once upon a time.
