5 Most Known Hackers in the World.

In the world of web where we get the global connectivity, it is far easier to break into someone’s personal zone. By personal, we do not just mean the social media. The world wide web which has become the hub of storing and restoring information, considered to be the safest vault, is a mere toy in the hands of a few computer geniuses. Hackers, Black Hat Hackers, villains, crackers, cyber-criminals, cyber pirates as they are well-known, throw a malicious software or virus at a system to gain the access to the desired information. Piqued by curiosity, they may perhaps break into your system too. Here are top 5 hackers or the whiz kids who put the world in awe with their dexterity.

1. Gary McKinnon

Gary McKinnon must’ve been a curious, restless child, for to gain information on UFOs, he thought it better to get a direct access into the channels of NASA. He infiltrated 97 US military and NASA computers, by installing virus and deleting a few files. All the efforts to satisfy his curiosity, but, alas, curiosity killed the cat. It was soon found that McKinnon was guilty of having hacked the military and NASA websites from his girlfriend’s aunt’s house in London. While entering and deleting the files from these websites wasn’t enough, McKinnon thought of shaming the security forces by putting out a notice on the website that said, “Your security is crap.” Well, looks like McKinnon was something, if he could shut down the US Military’s Washington Network of about 2000 computers for 24 hours, making the hack, the biggest military computer hack of all time!

2. LulzSec

LulzSec or Lulz Security, a high profile, Black Hat hacker group, gained credentials for hacking into Sony, News International, CIA, FBI, Scotland Yard, and several noteworthy accounts. So notorious was the group that when it hacked into News Corporations account, they put across a false report of Rupert Murdoch having passed away. While the group claims to have retired from their vile duties, the motto of the group, “Laughing at your security since 2011!” stays alive. There are assertions of the group having hacked into the websites of the newspapers like The Times and The Sun to post its retirement news. Many, however, claim that this group had taken it upon itself to create awareness about the absence of efficient security against hackers.

3. Adrian Lamo

Adrian Lamo decided to switch careers when he realized the potentials of his skills. He became a news when he hacked into Yahoo!, Microsoft, Google, and The New York Times. This, although culminated into his arrest, it later helped him gain the batch of an American Threat Analyst. A guy who would hack into top-notch accounts sitting in the spacious and comforting cafeterias, libraries, internet cafes, soon turned Wikileaks suspect Bradley Manning over to FBI. While Manning was arrested for leaking several hundred sensitive US government documents, Lamo went hiding or should we presume, undercover?

4. Mathew Bevan and Richard Pryce

Targeting the over-sensitive nerves, what Mathew Bevan along with his alleged partner Richard Pryce did, could have triggered great many issues between USA and North Korea. The duo hacked the US military computers and used it as a means to infiltrate the foreign systems. The crucial contents of Korean Atomic Research Institute were dumped into USAF system. However, the contents were majorly relevant to South Korea and hence, less volatile. But this, nonetheless, could have led to a huge international issue.

5. Jonathan James

The first juvenile to be imprisoned for a cyber-crime at the age of 16, Jonathan James or better known as c0mrade, hacked into Defense Threat Reduction Agency of US department. Further, he installed a sniffer that scrutinized the messages passed on between the DTRA employees. Not only did he keep a check on the messages being passed around, in the process, he collected the passwords and usernames and other such vital details of the employees, and further even stole essential software. All this cost NASA to shut down its system and to pay from its pocket $41,000. c0mrade, however, had a bitter ending as James committed suicide in 2008.
