learn hacker

This time it was the duty of one of my college Eyes "Computers and Society". The task this time is given directly by Mr. Dwi Atmodjo W P. Drs, M. Kom. task is to find what it is: 
Hacker definition according to the Laity, the Middle It, and The High IT 
Type - type of Hacker 
Advantage & Disadvantage Hacker in Social Society 

  

Wooooooookkkkkkkeeeeeeeeeeeehhhhhhhhhh ............................ 

  

Now let's start from the first. Hajime !!!!!!!!!!! 

  

Hacker Definition 

  

According to IT layman: 

Ø Hacker is a person who damaged a computer network 

Ø Hackers are people who steal other people's data through the Internet. 

  

According to people who know little about IT (IT Middle): 

Ø People who like to explore programs and systems, enthusiastic and expert in making the program, is capable of hacking, and pleased with the intellectual challenges with creative ideas. 

  

According to people who know about IT (Highly IT): 

Ø Hacker is a computer professional. They spent most of his time, dedicated computer skills and all things related to the IT world. These people are Internet experts, understand the world of computing. Your network administrator, think they understand exactly what they were talking about, most are also a hacker. 

Ø One who programs enthusiasticaly or who enjoysprogramming rather than theorizing about programming. (Guy L. Steele, et al. The Hacker's Dictionary) 

  

In addition, a hacker must also have CODES, like a journalist. Code of Conduct that is 

1. Able to access computers and the infinite totality. 

2. All information must be FREE. 

3. Do not believe in the authority, means extending decentralization. 

4. Do not use a false identity, such as the ridiculous pseudonym, age, position, etc.. 

5. Able to create beauty in the computer art. 

6. Computers can change lives for the better. 

7. The work will be undertaken solely for the sake of the truth of information that must be deployed spread. 

8. Do not uphold the commitment to defend the economic dominance of certain software industry. 

9. Hacking is the majority of weapons in the war against the encroachment of computer technology. 

10. Both Hacking and Phreaking is the only other way to disseminate information to the masses so that no stuttering in the computer. 

  

One is the famous Hacker Murpky Ian aka Captain Zap. 

Type - type of Hacker 

  

White hat is a term that refers to information technology to the ethical hackers showed a weakness in a computer system. White hat generally focuses its action on how to protect a system and provide ideas or opinions that could improve the weaknesses in the system temukannya., Which contradicts with the black hat is more focus on how the action through the system. 

  

Black hat hacker is a term referring to information technology to those crackers who break through the security computer system without permission, usually in order to access computers that are connected to the network. Black Hat Hackers are more likely to term its just a cracker who dismantle and destroy for personal gain 

  

  
Advantage & Disadvantage Hacker in Social Society 

  

Advantage: 

Much help in software development and security. For example there is an article that I quoted from a page about IT 

  

"The benefits in society Hacker 

  

Most of the literature mentioned that the terms and hacker culture was first used in 1961 when he had the opportunity to enjoy the MIT PDP-1 machine. DEC's first computer production has become a favorite toy, especially the MIT student who joined the Tech Model Railroad Club. They make programming tools, making a lot of programs, develop ethics, jargon and even ngoprek PDP-1 to become a video-game machine early generations. Culture is what later became known for the real hacker culture. The hackers in the Tech Model Railroad Club became the core team of research laboratories Artificial Intelligence (AI) MIT who became a pioneer in AI research in the world today. " 

  

DisAdvantage: 
Once caught destroying other people's systems, your name will be blackened and forever unappreciated by others 
Difficult to get a job 
Suspicion always will do bad things 


Ethics surf 

  

We start from a question: What is email it? It can be concluded that general and one-sided that the email or electronic mail is a mailbox that is the Internet. 

An email has address explaining who or what company and where the company is located. But not always so sure of. Example: iyan@digitalkreasi.co.id indicates that Mr.. Iyan work at Creative Digital companies in the country of Indonesia. 

Email address short serves as a post office box addresses (mailboxes) that carries the image of the institution. We have almost every person and institution has to have email addresses, email becomes a necessity as well as facsimile and phone. 

What is the advantage Home Page & Email compared to other conventional media? 

  • Internet (Home Page & Email) is available 24 hours a day, 7 days a week for 1 full year 

  • Your business can perform sales, promotions and public relations continuously without any time limitation. 

  • Customers may continue to contact you any time via email without having hindered by the constraints of time and hours of work and the time difference between countries. 

  • You can communicate over a full 24 hours with your customers everywhere. 

  • You can check all the mail that came through email wherever you are, without a hitch Time and Limit State. 

  • One of the most important thing and the last one ... the cost is very cheap and affordable. 

  

Sproull and Kiesler, Connections, MIT Press, 1993. Instead, provide evidence that direct mail information into an egalitarian structure - where all people equal. This fact can be found from the eGroups and mailing-active mailing list on the internet. 

Surely after discovering a variety of functions and the advantages the Internet including email, according to my thinking before you use it so-so we understand the more about ethics in the surf or known as netiquette. 

The paper itself can be assumed to be merely an introduction, and operating instructions prorgram email - which buttons to push or how to attach the image file can be viewed at the facility in an email. Such details would be different for each software package, see the relevant manuals and programs familiarize yourself feel free to read the help because often I get questions that are clearly explained. 

This guide alone I expect not only to show how to be polite, but also how to become more efficient, to write more clearly, and effectively. Of course what is written here does not rule die. There will be others who disagree with me on certain things, and this article diterbitkanya again because I just experienced something that ridiculous. 

But, if there is only one correct answer, this guide does not need to be written? My hope this guide will make you review your assumptions about the email, and help you be effective in an email to. Only then you can write according to the writing style that reflects your own personality. 


History Hacker and Cracker 

  

Hackers appeared in the early 1960s among the members of student organizations Tech Model Railroad Club in Artifisial Intelligence Laboratory Massachusetts Institute of Technology (MIT). Student group is one of the pioneers of the development of computer technology and they operate with a number of mainframe computers. The word hacker first appeared with a positive sense to refer to a member who has expertise in the field of computers and able to make computer programs better than what has been designed together. Then in 1983, growing hacker analogy to refer to someone who has an obsession to understand and master the computer system. 

  

The problem, in that year for the first time the FBI arrested a criminal group of computers The 414s are based in Milwaukee USA. 414 is their local area code. The group that came to be called a hacker was convicted of burglary 60 computers, from computers owned by Cancer Center Memorial Sloan-Kettering's computer to Los Alamos National Laboratory. One of the perpetrators are getting immunity for TESTIMONIALS, while the other 5 players get probation sentence. 

  

Then, further up other groups to mention themselves hackers, but it's not. They are (especially the men) who have the satisfaction of breaking through computer and phone-jockey (phreaking). True hackers call these people 'crackers' and do not like to hang out with them. True hackers crackers as people look lazy, irresponsible, and not too bright. Real hackers do not agree to say that with a person through the security has become a hacker. 

  

The hackers meeting each year which is held once every mid-July in Las Vegas. A meeting of the world's largest hacker is called Def Con. Def Con event to event is more exchange of information and technology related to hacking activities.

learn to be a hacker

Hackers with expertise can view & fix weaknesses in the computer software, usually later in openly published on the Internet for the system to be better. Unfortunately, few people take the evil use that information to crime - they are usually called cracker. Basically the world of hackers & crackers no different from the art world, here we are talking art Internet network security. 

I hope the science in network security is used for writing things that are good - not be a Hacker Cracker. Do not until you get karma for using science to destroy property of others. Moreover, at this time would need hackers in Indonesia increased by more dotcommers want to IPO in the stock market. Good name & the value of a dotcom could fall even become worthless if the dotcoms in the collapse. In this case, the hacker is expected to be a security consultant for the dotcommers - because human resources of police & security forces Indonesia is very, very weak & pathetic in the field of Information Technology & the Internet. I can not help cybersquad, private cyberpatrol perhaps necessary for survival in the culture dotcommers Indonesia on the Internet. 



Various Internet network security techniques can be easily obtained on the Internet, among others in http://www.sans.org, http://www.rootshell.com, http://www.linuxfirewall.org/, http:// www.linuxdoc.org, http://www.cerias.purdue.edu/coast/firewalls/, http://www.redhat.com/mirrors/LDP/HOWTO/. Some of these techniques in the form of books of his several hundred pages that can be taken free of charge (free). Some Frequently Asked Questions (FAQ) about the network security can be obtained in http://www.iss.net/vd/mail.html, http://www.v-one.com/documents/fw-faq.htm. And for the experimenter some scripts / programs that have become available, among others in http://bastille-linux.sourceforge.net/, http://www.redhat.com/support/docs/tips/firewall/firewallservice.html . 


For readers who want to gain knowledge about the network and can be downloaded for free from http://pandu.dhs.org, http://www.bogor.net/idkf/, http://louis.idaman.com/idkf . Several books softcopy form that can be taken free of charge can be taken from http://pandu.dhs.org/Books-Online/. We have to thank especially the Scout team led by I Made Wiryana for this. At this moment, I do not really know the place Indonesian is an active discussion discuss hacking techniques are - but it may be partly discussed in the mailing list information such as the kursus-linux@yahoogroups.com & linux-admin@linux.or.id operated by Indonesian Linux Users Group (KPLI) http://www.kpli.or.id. 


The simplest way to see the weakness of the system is to seek information from various vendors such as the http://www.sans.org/newlook/publications/roadmap.htm # 3b of the weaknesses of the system they have created yourself. In addition, monitoring the various mailing lists on Internet-related security such as network http://www.sans.org/newlook/publications/roadmap.htm list # 3e. 


Explained by the Front-line Information Security Team, "Techniques Adopted By 'System Crackers' When Attempting To Break Into Corporate or Sensitive Private Networks," fist@ns2.co.uk http://www.ns2.co.uk. A Cracker generally men aged 16-25 years. Based on the statistics of Internet users in Indonesia is in fact the majority of Internet users in Indonesia are young children at this age, too. It's age is an ideal age in the new studying science, including the Internet, very unfortunate if we did not succeed to the 25,000 schools menginternetkan Indonesian s / d in 2002 - because the confluence of Indonesia's future in the hands of young children we are. 


Well, the young cracker cracking is generally done to improve / use of network resources for its own sake. Generally, the cracker is opportunis. Seeing weakness carry out the program with the system scanner. After gaining root access, a cracker will install the back door (backdoor) and close all existing general weakness. 


As we know, most of the company / dotcommers will use the Internet to (1) web hosting of their servers, (2) e-mail communication and (3) provides access to web / internet to its employees. Separation of Internet and Intranet networks generally performed using techniques / software firewall and proxy servers. Seeing the use of the above conditions, the weakness in the system can generally penetrate through the mail server for example with external / outside that is used to facilitate access to the mail out of the company. In addition, by using aggressive-SNMP scanner & a program that forced SNMP community strings can change a router into bridge (bridge) which can then be used for a stepping stone for entry into the company's internal network (Intranet). 


In order for crackers are protected at the time of the attack, the technique cloacking (cover) is done by jumping from the previous machine has been compromised (defeated) via telnet or rsh program. At intermediate machines using Windows attack can be done by jumping from Wingate program. In addition, the jump can be done through a proxy device that the configuration is less good. 


After a successful jump and into other systems, a cracker like to probing the network and gather information needed. This is done in several ways, such as (1) use nslookup to run the command 'ls', (2) view HTML files on your web server to identify other machines, (3) to see various documents on the FTP server, (4) relate to the mail server and use the command 'expn', and (5) to a user finger on machines other external. 


The next step, a cracker will identify a trusted network component by whatever system. Network components are usually machine and server administrators who are usually considered the most secure in the network. Start by checking the access & NFS export to a variety of critical directories like / usr / bin, / etc and / home. Exploitation of the machine through the weakness of Common Gateway Interface (CGI), with access to the file / etc / hosts.allow. 


Next cracker must identify the network components that are weak and can be conquered. Crackers can use in Linux programs like ADMhack, mscan, nmap and many other small scanner. Programs like 'ps' & 'netstat' on the make trojan (remember the Trojan horse story? The classic story of ancient Greece) to hide the scanning process. For cracker advanced enough to use aggressive-SNMP scanning to scan equipment with SNMP. 


After the crackers have identified a weak network components and can be conquered, then the cracker will run programs to conquer the weak daemon program on the server. Daemon program is a program on a server that normally run in the background (as daemon / demon). The success of the program conquer this daemon will allow a Cracker to gain access as 'root' (the highest administrator in the server). 


To remove tracks, a cracker usually do clean-up operation 'clean-up' operation by cleaning the log files. And add the program to enter from the back door 'backdooring'. Changing file. Rhosts in / var / bin for easy access to the machine via rsh conquests & csh. 


Furthermore a cracker can use a machine that had conquered for his own benefit, such as taking sensitive information that should not be read; mengcracking another machine with a jump from the machine in the conquered; install the sniffer to see / record the traffic / communications passing; can even turn off the system / network by running the command 'rm-rf / &'. The latter will be very fatal consequences because the system will be destroyed at all, especially if all the software on the hard disk Lay. Process re-install the entire system must be done, will be confusing if it is done on machines that run mission-critical. 


Therefore, all machines & routers critical missions should always check the security & the patch by the newer software. Backup is very important especially on machines that run mission critical behavior that was saved from a cracker that disable the system with 'rm-rf / &'. 


For those of us who wrestle daily on the Internet are just going to really appreciate the existence of hackers (not Cracker). Because hackers thanks to the Internet is there and can we enjoy today, even kept in repair for a better system again. Various weaknesses in the system due to improved intelligence colleagues hackers often they will be working on improvements. voluntarily because of his hobby. Moreover, often the result of his hacking distributed freely on the Internet for the purposes of the Internet community. A cultural values & Noble mutual cooperation instead grow in the Internet virtual world that typically seem futuristic and far from the social sense. 


Development of the hobbiest hackers become critical to the sustainability / survival of the spacecraft Internet dotcommers Indonesia. As one of fact, in the near future Inshallah around mid April 2001 will be held hacking competition on the Internet to break into a server that has been in the first set. Hacking is in Motori competition by young children in Indonesia Linux User Groups (KPLI) Semarang is mobilized by young people like Kresno Aji (masaji@telkom.net), Agus Hartanto (hartx@writeme.com) & Lekso Budi Handoko (handoko @ riset.dinus.ac.id). Like most young kids the other, they are generally capitalized, insufficient - support & sponsorship would be very useful and awaited by the young fellow is. 


Hopefully this will add to the spirit of readers, especially young readers, to move in the exciting world of hackers and challenging. If it says Captain Jean Luc Picard in the movie startrek Next Generation, "To boldly go where no one has gone before".
