V - Info : The Black Worm Virus

The Blackworm virus is malware which spreads itself primarily through email attachments. The risk varies depending on which version of the virus your computer has contracted.

The Blackworm virus can overwrite various document files, including Microsoft Word documents, Excel spreadsheets, compressed files such as .rar and .zip files, Portable Document Files and others. This document corruption takes place on the third day of every month.

It can also disable your antivirus software. So, be careful when you use your internet. I will tell you about how to remove the black worm in a new post.

LA 1 : CPU

What is a CPU?

The Central Processing Unit, or CPU, is considered the brain of a computer. Without this vital component, the computer wouldn't be able do any of the functions it is capable of doing. Basically, it is a chip that handles the moving and processing of data.

With each new upgrade, the CPU is getting faster and more powerful. Speed and reliability is the name of the game when consumers are comparing CPU chips in the new PCs. For some, the brand of CPU is the major selling point for many when buying a new computer. The faster and more powerful the CPU, the more the computer will sell.


How Does it Work?

The CPU sits in the motherboard as the central unit. All of the other hardware components and programs installed on the system must go through the CPU before their function can be carried out. The CPU's job function is important and enormous in scale.

When a function, program or piece of data is called, the CPU pulls it from Random Access Memory (RAM) and any other hardware in order to process it. The CPU then reads the instructions associated to the task before sending it back to RAM. The instructions that the CPU receives pertains to calculations and data transportation. The system bus is the trail that the data must travel before it is executed. It is the CPU's job to make sure that the data is guided through the system bus to be processed by the CPU and then on to the next step. With every stop on the system bus, the CPU makes sure that the data gets there in the correct order.

LA 1 : Cyber Law

Cyber law describes the legal issues related to use of inter-networked information technology. It is less a distinct field of law in the way that property or contract are, as it is a domain covering many areas of law and regulation. Some leading topics include intellectual property, privacy, freedom of expression, and jurisdiction.

There are four types of Intellectual Property protection. They are patents for invention, trademarks for brand identity, designs for product appearance and copyright for material. Intellectual property laws are needed:

• to establish & safeguard the intellectual property which refers to works created by inventors, authors and artists.
• as businesses today continue to expand globally

Privacy can be protected by privacy law and utilities software.

Issues of jurisdiction have quickly come to the fore in the era of the Internet. The Internet does not tend to make geographical and jurisdictional boundaries clear, but Internet users remain in physical jurisdictions and are subject to laws independent of their presence on the Internet.As such, a single transaction may involve the laws of at least three jurisdictions:

1) the laws of the state/nation in which the user resides.

2) the laws of the state/nation that apply where the server hosting the transaction is located.

3) the laws of the state/nation which apply to the person or business with whom the transaction takes place.

What Is Blog???

So what is blog?? Blog is a "Web log",usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.

Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketches (sketchblog), videos (vlog), music (MP3 blog), audio (podcasting), which are part of a wider network of social media.

Micro-blogging is another type of blogging, one which consists of blogs with very short posts. As of December 2007, blog search engine Technorati was tracking more than 112 million blogs. With the advent of video blogging, the word blog has taken on an even looser meaning — that of any bit of media wherein the subject expresses his opinion or simply talks about something.

How to Be a Good Hacker

Hacking is a difficult process and if you don't have experience in this field, you might end up being on the wrong side of the law. Also if you are not certified as a hacker and you don't have permission from the owner to hack their computer, then it is illegal to hack someone else computer.

Step 1 :Learn a programming language. Python is a much easier programming language to learn then C++. Learning server side languages such as PHP will help you immensely.

Step 2 :Use a *nix terminal for commands. Cygwin will help emulate this for Windows users. The tools in this article can be found for Windows based machines. You should also consider using Linux or BSD, which are both more flexible, more reliable, and more secure.

Step 3 :Try securing your machine first. Make sure you fully understood all common techniques, including the way to protect yourself.

Step 4 :Know your target. The process of gathering information about your target is known as 'enumeration'. You can use the ping utility to see if the target is 'alive, don't trust the results of the the ping utility as it uses the ICMP protocol and easily be shut down by system administrators.

Step 5 :Determine the operating system (OS). This is important because how can you gain access to a system if you don't know what the system is!. Try pOf, or nmap to run a port scan. This will show the ports that are open on the machine, the OS, and can even tell you what type of firewall or router they are using so you can plan a course of action.

Step 6 :Find some path or open port in the system. Common ports such as FTP (21) and HTTP (80) are often well protected, and possibly only vulnerable to exploits yet to be discovered. An open port 22 is usually evidence of an SSH service running on the target, which can sometimes be brute forced.

Step 7 :Crack the password or authentication process. There are several methods for cracking a password, including brute force. Using brute force on a password is an effort to try every possible password contained within a pre-defined dictionary of brute force software. You may try using Rainbow Tables for fastest password cracking.

Step 8 :Get super user (root) privileges if targeting a *nix machine, or administrator privileges if taking Windows systems. To see all the files on a computer you need super user privileges. For routers this is the "admin" account by default for Windows, this is the Administrator account, etc.

Step 9 :Use various tricks. Often to gain super user status you have use tactics such as creating a "buffer overflow" which is basically causing the memory to dump and allowing you to inject a code or perform a task at a higher level then you're normally authorized.

Step 10 :Create a backdoor. nce you gained full control over machine, it's best to make sure you can come back one day. This can be done by backdooring important system service, such as SSH server. Your backdoor may be removed upon next system upgrade, so only experienced hackers would backdoor the compiler itself, so using compiled software would be a way to come back.

Step 11 :Cover your tracks. Never ever let the administrator know that the system is compromised. Do not change the website, do not create more files than you really need. Act as fast as possible. If you patched a server like SSHD, make sure it has your secret password hard-coded.

Arithmetic logic unit

(Arithmetic Logic Unit) The high-speed CPU circuit that does calculating and comparing. Numbers are transferred from memory into the ALU for calculation, and the results are sent back into memory. Alphanumeric data are sent from memory into the ALU for comparing. The results are tested by GOTOs; for example, IF ITEM EQUALS ITEM GO TO UPDATE ROUTINE.

Some chips have multiple ALUs that allow for simultaneous calculations. For example, Chromatic Research's Mpact media processor chip had 450 of them. It allowed audio, video and other multimedia processes to be performed simultaneously. See Mpact chip.

An ALU in 1957

Thirty Years Later
The ALU embedded within this 386 chip would fit on the end of a pencil eraser with room to spare. (Image courtesy of Intel Corporation.)

In computing, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit (CPU) of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The processors found inside modern CPUs and graphics processing units (GPUs) have inside them very powerful and very complex ALUs; a single component may contain a number of ALUs.

Mathematician John von Neumann proposed the ALU concept in 1945, when he wrote a report on the foundations for a new computer called the EDVAC.

A typical schematic symbol for an ALU: A & B are the data (registers); R is the output; F is the Operand (instruction) from the Control Unit; D is an output status.

V-Info: How to make a virus

I used to think that making viruses had something to do with programming skills. I thought writing a program that could copy itself, spread itself, hide in other programs or files, find its way around on all these different computers, that surely had to be the summum of programming.

Maybe this once was true. Back in the old days, when viruses ware written in assembler, were small enough to hide in the boot sector of a floppy disk, were able to attach themselves to a file without anyone noticing (and files were quite small those days), had stealth capability, and could influence your hardware directly, bypassing the operating system.

So maybe, maybe in those days, creating viruses could be seen as an achievement, or as a sport. Now, any fool can do it. And judging by the number of viruses, a lot of them do. Here's how.

1. Search the web for something like "Virus Construction Tool" or "Internet Worm Generator". Download it.


2. Run the program (click on its icon).


3. Fill in the form. Choose interesting names.

4. Check the boxes to indicate how you want this virus / worm to spread (e-mail, irc, ...)

5. Choose your options for 'payload'

6. Then click "Done".

7. Click "create virus" or "generate"
8. Save the file
9. Run it to see if it works

Akibat Tak Buat Kerja

Hari ini merupakan hari yang malang buat sesiapa tak buat kerja ICT. Hampir 95% daripada seluruh murid dalam kelas didenda kerana x buat dan tak siap nota...

Denda yang dikenakan untuk x buat nota tu sebenarnya adalah pumping 25 kali tapi duk bohong cikgu ulang balikdari awal . Bagi yang bohong pula kena penampar 2 kali.

Kesimpulannya, sesiapa yang terasa tu, insaflah dan mulakan sikap baru yang rajin buat kerja.
Sekian,terima kasih.

V-Info : Details About Computer Virus

Today, i will talk about computer virus more detail. If you have any opinion, we can share.

I start from definition. In computers, a virus is a program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document. Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette or CD. The immediate source of the e-mail note, downloaded file, or diskette you've received is usually unaware that it contains a virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer. Some viruses are benign or playful in intent and effect ("Happy Birthday, PEKASAM!") and some can be quite harmful, erasing data or causing your hard disk to require reformatting. A virus that replicates itself by resending itself as an e-mail attachment or as part of a network message is known as a worm.

Generally, there are three main classes of viruses:


File infectors. Some file infector viruses attach themselves to program files, usually selected .COM or .EXE files. Some can infect any program for which execution is requested, including .SYS, .OVL, .PRG, and .MNU files. When the program is loaded, the virus is loaded as well. Other file infector viruses arrive as wholly-contained programs or scripts sent as an attachment to an e-mail note.

System or boot-record infectors. These viruses infect executable code found in certain system areas on a disk. They attach to the DOS bootsector on diskettes or the Master Boot Record on hard disks. A typical scenario (familiar to the author) is to receive a diskette from an innocent source that contains a boot disk virus. When your operating system is running, files on the diskette can be read without triggering the boot disk virus. However, if you leave the diskette in the drive, and then turn the computer off or reload the operating system, the computer will look first in your A drive, find the diskette with its boot disk virus, load it, and make it temporarily impossible to use your hard disk. (Allow several days for recovery.) This is why you should make sure you have a bootable floppy.

Macro viruses. These are among the most common viruses, and they tend to do the least damage. Macro viruses infect your Microsoft Word application and typically insert unwanted words or phrases.
The best protection against a virus is to know the origin of each program or file you load into your computer or open from your e-mail program. Since this is difficult, you can buy anti-virus software that can screen e-mail attachments and also check all of your files periodically and remove any viruses that are found. From time to time, you may get an e-mail message warning of a new virus. Unless the warning is from a source you recognize, chances are good that the warning is a virus hoax.
The computer virus, of course, gets its name from the biological virus. The word itself comes from a Latin word meaning slimy liquid or poison.

PLEASE COMMENT!!! dan bacalah sesungguhnya membaca adalah perkara yang paling mudah.

10 Sebab Untuk Blog

Blog itu sendiri juga mempunyai beberapa jenis. Selain blog biasa yang bersifat jurnal dan peribadi, ada juga photoblog, vblog, podcast dan banyak lagi. Photoblog lebih memaparkan gambar berbanding isi, tambahan pula untuk mengambil gambar pada masa ini adalah amat mudah. Rata-rata handphone memiliki camera digital. Vblog atau disebut juga vlog pula adalah blog terkini yang memaparkan Video sebagai isi utamanya. Podcast pula adalah blog dengan keutamaan audio.

Blog juga dibina biasanya berdasarkan kepada tajuk-tajuk tertentu, seperti blog automotif, blog teknologi, blog fesyen, blog gajet-gajet terkini dan sebagainya. Walaupun begitu, blog peribadi biasanya mendahului senarai yang paling banyak dibina.
Tidak kiralah, yang mana satu anda mahu. Berikut adalah 10 sebab mengapa anda perlu mempunyai blog!

1 - EMOSI : Hidup di lokasi Urban juga metropolitan ini selalunya berada dalam keadaan sibuk, terkejar-kejar, banyak kerja, tidak cukup masa dan bermacam masalah pada setiap hari. Manakala masih belajar pula dengan masalah di tempat belajar dan kawan-kawan. Setiap orang ada masalah. Masalah harian samada yang lazim mahupun yang jarang berlaku, akan membawa kita kepada satu pembunuh senyap iaitu tekanan! (Stress!). Semakin banyak tekanan semakin parahlah emosi sehingga membawa kepada masalah psikologi!
Pada kebiasaanya, kita meredakan tekanan dengan meluahkan pada kekasih, keluarga, kawan-kawan dan rakan sekerja? Bagaimana jika semua mereka tidak ada berdekatan, atau mungkin kita sendiri tidak mahu memberitahu mereka?
Ya! Menaiplah di blog anda, luahkan perasaan marah, kecewa, benci, terkilan dan sebagainya. Dengan ini, tekanan anda mungkin sudah berkurangan. Walaupun tidak sebanyak mana mungkin, tetapi pasti ada kesannya.
Apatah lagi apabila ada maklumbalas(comment) dari kenalan online anda ataupun sesiapa yang anda tidak ketahui yang memberikan kata-kata peransang dan semangat untuk anda. Memberikan anda tip-tip mengatasi sesuatu masalah yang mungkin pernah dilalui mereka.
Selain itu, perasaan gembira juga anda boleh hebohkan di blog anda untuk di kongsikan dengan sesiapa sahaja. Bagus bukan? Blog adalah terapi emosi.

2 - EKONOMI :Ketika ini, dimana-mana juga orang akan berkata, blog boleh mendatangkan duit! Benarkah? Ramai juga yang terjebak dalam kancah ini dan kecewa, kerana blog-blog mereka gagal mendatangkan duit. Materialistik sungguh dunia hari ini.
Membuat blog yang boleh menghasilkan pendapatan bukanlah semudah yang anda fikir. Perlu ada perancangan dan ilmu dalam bidang-bidang berkaitan. Blog yang menghasilkan pendapatan adalah sama seperti berniaga, anda perlu berfikiran seperti seorang ‘businessman’. Seorang peniaga yang mempunyai perancangan dan bertindak berdasarkan keadaan.
Ada banyak cara menghasilkan pendapatan dengan blog, secara ringkasnya begini:Bina blog yang menarik dan mengemaskininya dari masa kesemasa sehingga anda mempunyai pelawat yang ramai setiap hari. Dengan pelawat yang ramai dari masa ke semasa, anda boleh menyertai program-program pengiklanan yang ada yang mana memberikan anda komisyen atau menjual iklan terus kepada sesiapa yang mahu. Selain itu, menjual blog anda kepada sesiapa yang berminat dengan harga yang tinggi. (sudah tentu bukan blog peribadi anda)
Tahukah anda, wujud satu kerjaya baru digelar “ProBlogger” iaitu ‘pemblog profesional!’
*Blog yang menjana pendapatan adalah merupakan bab yang besar dan memerlukan huraian yang jauh lebih panjang dan ruang lingkup yang luas. Saya akan buat artikel menyeluruh pada masa hadapan jika berpeluang..

3 - DIARI: Kita menulis segala yang berlaku setiap hari di dalam diari. Lazimnya perempuanlah!. Tetapi lelaki juga boleh mempunyai diari, “Diari Seorang Lelaki” mungkin.
Ingatkah kita… apa yang berlaku pada hari ini, tetapi setahun yang lalu? Sudah tentu tidak bukan? Nah.. alangkah baiknya jika semua hidup kita ada catatan. Kadangkala, saya sendiri membaca apa yang saya lakukan pada tahun lepas didalam blog saya. Ada masanya saya ketawa sendiri, juga gembira dengan perkara-perkara menarik yang dilakukan bersama kawan-kawan, ada masanya kita mungkin kagum dengan diri kita sendiri dengan apa yang kita lalui beberapa tahun lalu!.
Oh Ya!, apa yang lebih menarik, ada juga blog ibu-ibu yang merakamkan cerita dan gambar-gambar anak mereka dari saat dilahirkan, merangkak, mula bercakap perkataan pertama sehinggalah boleh berjalan mahupun sudah mula bersekolah!.
Blog mungkin ‘public diary’, bermaksud boleh di baca oleh sesiapa. Tetapi jangan bimbang, sesetengah blog mempunyai fungsi pos peribadi (private). Ada yang memerlukan kata laluan untuk dibaca!.
Setiap hari kita akan jumpa keyboard dan monitor. Kita lebih mengenal keyboard daripada pen dan buku. Jari kita lebih pantas menaip daripada menulis menggunakan pen di kertas. Atas sebab ini… tiada keraguan bahawa blog adalah diari terkini!
Seterusnya!!!!
Lagi 7 tu lain kali sajalah.
