इथीकल हैकींग टीप्स

Hacking is an engaging field but it is surely not easy. To become a hacker one has to have an attitude and curiosity of learning and adapting new skills. You must have a deep knowledge of computer systems, programming languages, operating systems and the journey of learning goes on and on. Some people think that a hacker is always a criminal and do illegal activities but they are wrong. Actually many big companies hire hackers to protect their systems and information and are highly paid. We have prepared a list of 12 most important steps necessary to become a hacker, have a deeper look


UNIX/LINUX is an open source operating system which provides better security to computer systems. It was first developed by AT&T in Bell labs and contributed a lot in the world of security. You should install LINUX freely available open source versions on your desktops as without learning UNIX/LINUX, it is not possible to become a hacker.


C programming is the base of learning UNIX/LINUX as this operating system is coded in C programming which makes it the most powerful language as compared to other programming languages. C language was developed by Dennis Ritchie in late 1970’s. To become a hacker you should master C language.


It is important for a person in the hacking field to learn more than one programming. There are many programming languages to learn such as Python, JAVA, C++. Free eBooks, tutorials are easily available online.


Another important and essential step to become a hacker is to be good at networking concepts and understanding how the networks are created. You need to know the differences between different types of networks and must have a clear understanding of TCP/IP and UDP to exploit vulnerabilities (loop holes) in system.


Understanding what LAN, WAN, VPN, Firewall is also important.

You must have a clear understanding and use of network tools such as Wireshark, NMAP for packet analyzing, network scanning etc.


It is essential for a hacker to learn more than one operating system. There are many other Operating systems apart from Windows, UNIX/LINUX etc. Every system has a loop hole, hacker needs it to exploit it.


To become a successful hacker you need to master the art of cryptography. Encryption and Decryption are important skills in hacking. Encryption is widely done in several aspects of information system security in authentication, confidentiality and integrity of data. Information on a network is in encrypted form such as passwords. While hacking a system, these encrypted codes needs to be broken, which is called decryption.


Go through various tutorials, eBooks written by experts in the field of hacking. In the field of hacking, learning is never ending because security changes every day with new updates in systems.


After learning some concepts, sit and practice them. Setup your own lab for experimental purpose. You need a good computer system to start with as some tools may require powerful processor, RAM etc. Keep on Testing and learning until you breach a system.


Vulnerability is the weakness, loop hole or open door through which you enter the system. Look for vulnerabilities by scanning the system, network etc. Try to write your own and exploit the system.

An open source computer security project helps you a lot in polishing and testing your hacking skills. It’s not a piece of cake to get it done. Some organizations such as MOZILLA, APACHE offer open source projects. Contribute and be a part of them even if your contribution is small, it will add a big value to your field.


Learning is the key to success in the world of hacking. Continuous learning and practicing will make you the best hacker. Keep yourself updated about security changes and learn about new ways to exploit systems


Most important for a hacker is to make a community or join forums, discussions with other hackers worldwide, so that they can exchange and share their knowledge and work as a team. Join Facebook groups related to hacking where you can get more from experts.

Hackaday links: February 21, 2011

PCB Stand

Part PCB, part old IC, and held together with hot glue. It doesn’t take much to make this electronics stand, but it’ll certainly add to the geek level of your desk.

Decorate with light


This busy living room is actually decorated all in white. The patterns that give it life are on lend from a projector and what we’d imagine is some fantastic software. [Thanks MDV]

Flashing butt on your bike

[Eli] sewed lights and flex sensor into her jeans. Now her butt flashes in heart-shaped patterns as she rides. She actually robbed one of the flex sensors from this project to complete that explosive high-five project.


Mini-rake’s progress


A lathe and some sand that needs tending is all that [Spatula Tzar] needed to get this zen garden rake under way. We like how she used a vacuum bag to infuse the wood

Paper and electron



This collection of musical projects forsakes common substrates and builds the mess of circuit boards on pieces of paper. Not much information but the strangeness is worth a look.

DIY emergency lighting system


When the power goes out at home, what do you do? Most of us probably scramble around the house looking for a flashlight. [Gigawatts] wanted a better solution, so he built an emergency lighting system based off a standard household UPS. A while back he had constructed a relay-switched outlet box to help periodically restart his cable modem which would get hung up a little too often for his liking. Since changing Internet providers, he no longer needed the switched outlet box, and was looking for a way to reuse it.

He hooked up the outlet box into the “battery powered” side of the UPS, and inserted a light bub into the normally closed half of the switch box. A 5v power supply was hooked into the “surge protection only” side of the UPS and is used to keep the relay switched. This causes the half of the switch box that is normally closed to remain open, and the light switched off. When power is lost, the 5v supply no longer switches the relay, and the light is turned on – powered by the UPS battery.

This is quite a useful hack if you happen to have a spare UPS sitting around – it sure beats scrambling around searching for a flashlight in the dark!

NES game pad wireless light commander


Annoyed that the new lights he bought for his apartment lacked power switches, Instructables user [p.arry.drew] decided to install a pair of wireless light switches. Not content to use the remotes separately, he decided to see if he could cram them both into an old NES controller, making for a nice all-in-one wireless light commander.

He disassembled the light switch remotes, cutting off a bit of the battery contacts to ensure they fit in the game pad. He then pulled apart his NES controller, removing the cord and adding some foam padding to ensure that the buttons fully contacted the wireless switches when pressed. A few bits of wooden dowel were added to keep everything in place, then the controller was reassembled.

His creation makes for a very convenient method of controlling several light switches from once source, plus the packaging is pretty handsome as well. These remote light switching solutions seem to be all the rage lately, so keep them coming!

Read on for a quick video of his remote light switches in action.

Ultrasmall Arduino


[Fabio Varesano's] new Arduino compatible board packs a full power punch in a ultra compact layout, measuring at 20.7×15.2 mm, the Femtoduino is probably the smallest 328 based Arduino compatible board around. Most of the staples are present, an QFN atmega328, an MIC5205 low dropout regulator good for a couple hundred milli amps, 16MHz ceramic resonator, reset, power indicator and pin 13 LEDs, but you will need to provide your own serial connection (FTDI, MAX232 etc) and another AVR programmer to get the Arduino boot loader onto the chip.

Since the board is small (smaller than a pro mini) it is not directly breadboard friendly. Even though the hole spacing is 0.05 inch, the size is large enough for “normal” wire to fit into fine, if you wish to use 0.1 inch spacing there is a handy break out board you can make where the Femtoduino just snaps in.

Everything needed to make one of your own is provided on the website, schematics, kicad files, bill of materials, Gerbers for both the board and the breakout board, though we would like to see this as a pre-made board soon, join us after the break for a video and see why.

Farmbot


Prospero is the working prototype of an Autonomous Micro Planter, which is intended to be unleashed as a swarm. Using a Parallax propeller mounted on a Lynxmotion AH3-R hexapod body, though we have a ton of different ideas on hexapods if you find the price of the body to be out of budget.

Inputs to the machine are pretty standard robot fare like infrared, and ultrasound. Outputs on the other hand are more interesting, for example spray paint, retractable drill, seed dispenser, and of course a stack of servos.

Arming a robot with a drill and a can of spray paint sounds like a recipe for hours of fun, but it does have a job to do. Walking around, the bot stops and checks the ground below it, and if the ground is ok to seed, a small auger drill flips down from the robot’s belly. After drilling a hole, a seed is dropped, then covered over with a scoop on the back of the drill. Finally the seeded the spot is marked with white paint and the robot moves on.

Though its a prototype and not fully formed yet, its an interesting thing to see, so join us after the break for a video.
