Hacking means getting access to information/resources that you are not authorized to view/use. For example getting inside somebody’s computer to steal information, corrupt their system or use their computer/mobile to send or receive information etc.
Hacking can be good as well as bad. At times companies use “penetration tests” to ensure that their networks are safe and their applications are robust. At the same time there is another community which always tries to use hacking to damage networks, files and information. Bad hackers use tools and knowledge with malicious intent to damage other’s resource, information and data. Hacking can be categorized in various ways, for example
1) When you have physical access to computer a) When you can access the hardware directly – Change boot parameters to rewrite password files. b) When you can’t access hardware but can use console – get superior privileges to run command to give you complete access
2) When target device is on network – Using port scanners determine what is running and how to exploit it.
3) Memory hacking – Hacking various application variables in memory. For example cheats in PC games.
4) Application hacking – using vulnerabilities in application to get super user access
5) Mobile hacking – for example duplication of SIM to listen to other guys phone conversations.
6) Network hacking – to use specific resources of a network. For example an organization has hosted some data on private cloud which you want to download. You can hack the network to route your packets to target device and get the desired data.
7) Specialized hack – for example hacking a Wifi router. You can gain access to any of the wifi which is having WEP keys etc. It gives you an ability to access the network connected to wifi. Another example is that somebody is chatting with you and you want to scan his/her computer. You can do it with specific applications which can peep into others computer on network.
Hacking in most cases is a serious punishable offense. Whether it is good or bad you need to ensure you spoof your ip and mac.
Now the most interesting question arise.. why people get into hacking? For some its quick money, for some it’s a way to demonstrate their knowledge and for some .. it’s about killing time. But no matter what, not all hackers are bad. Many good hackers try their best to ensure we can use a safe network and applications.
Usually hackers are also categorized in three categories
1) Black Hat Hackers – bad guys. Run DDOS and other malicious stuff
2) Grey Hat Hackers - Good guys but are ready to break the law to achieve what they want
3) White Hat Hackers – Good guys always work within guidelines specified by local law enforcement agencies. These guys are experts in figure out security holes and bringing it out in the notice of community.
Will try to cover each point in separate posts later.
