As I had no option to opt with, I finally chosed to study MSc Integrated Computer Science in Anna University in 2006. We are exposed to some new things in Anna University campus while the other colleges lack that. MSc Integrated course was started only from my brother’s batch of 2001. We were only a few in the class at the beginning of the 1st year but later a few of our mates joined us. As I was a day scholar at the 1st year i couldnt get much opportunity to move with those mates. I always thought of studying with people who are from different places but it didnt work as most them are from chennai. We enjoyed our English class a lot.We were the first batch to have Kurukshetra fest and it was partially a success. We had some memorable days during the Techofes, the cultural fest of Anna University and we had a chance to see some of the cine celebrities of Tamil Nadu. We made some hangouts to theatres, beach and some shopping complex. On overall in my first year, we had only a little opportunities to cherish with.

I attended a workshop in Kurukshetra, the Techfest of Anna University in January. I write this blog to share some of the hacking tools i have known during that 3 hours of workshop. Hope everybody might have known the fundamentals and i dont think i need to start it from scratch. Hackers is of two types: Internal and External

Internal hackers pose the greatest threat to the IT systems of the world’s largest financial institutions, according to the 2005 Global Security Survey.

1. GetAdmin – This is a hacker utility which exploits flaws in MS Windows NT 4 OS and changes the administrative privilege of an account ie.any guest account can be changed to an administrator of the network.
Note: It doesn’t work in later version of windows
2. PipeUpAdmin – It is same as GetAdmin.But it works in MS Windows 2000. It has more enhanced features than GetAdmin.

Privelege Escalation is the process of exploiting a bug in an application to gain access to protected resources in the network. Cross Zone Scripting is a type of attack in which a website subverts the security model of web browsers so that it can run privilege escalationmalicious code on client computers. Vulnerability can be reduced by installing server packs and patches.

Password sniffing is an act of finding the password to gain access to the main system.
LC4 or L0phtCrack – This the most frequently used software for password sniffing. The good intention of this is that if the system admin has forgot the password then he can find the password within a minute. The bad intention is that it is used by hackers who can get all the passwords of a company within a minute. It usually uses the dictionary attack.

Session hijacking is the act of taking control of a user session after successfully obtaining or generating an authentication session ID. T sight Realtime – Once this software is connected to another system,the whole system is hijacked. A new window is opened in the hacker window and whatever the victim types over there Tsight display it in the hacker screen.

Port scanning software imply sends out a request to connect to the target computer on each port sequentially and makes a note of which ports responded or seem open to more in-depth probing.nmap is the mostly used software for port scanning.

Atlast i would conclude by listing some of the trojans and hacking tools with their use:

1. smbdie – This can kill the computer
2. netbus – trojan which can access the victim computer
3. elitewrap – this binds two exes which is used to combine a data file with a virus.

Note:

Some of the accurate definitions of the hacking tools are taken from Wikipedia

After India got Independance in 1947, IITs are formed and it is considered one of the prestigious institutions of the country till now. Only about 15000 juntas are selected from 3 lakh aspirants through their competitive test IIT-JEE which consists of 2 hours test of 3 papers each. In 2003, all RECs are united together under a common examination AIEEE which is 3 hour exam and it is open to all people. Until the unification of RECs the admission to REC are done according to the procedure of the their respective state in which it is located. In the recent survey of Top ten Engineering Colleges in India Today, Anna University finds a definite place in the top ten most of the times. Yet the admission to the college is based on 12th grade marks.

Tamil Nadu State Board 12th grade syllabus is actually a precise version of CBSE. It can never be compared with the CBSE 12th grade syllabus. Thus scoring marks is easier and most of them cram things and rewrite the exact answer as it is in the text book. SRV, a boarding school at Rasipuram near Salem are the experts in making the students to cram things exactly as it is in the Text book. The 12th grade marks should be kept only as Acads like our 10th grade marks and it should not be qualification for the admission to the college. A general category student who may have a high IQ but if he makes a small error in his 12th grade maths paper and it makes a lot of differences in his career. Admission to the colleges should be made only through competetive exams which consists of multiple choice questions. Another reason is that only a few percent of the seats are allocated for other state students and these restrictions should be broken and it should be open for the whole country.

Another point is that when my brother was studying his first year he has the option to study any foreign language like French, German, Japanese etc. But it lacks in my college days as they have made it english as the compulsary for all. This sucks!!!

Expecting this change to happen sooner in the coming years…
