The World's Worst Viruses
The World's Worst Viruses
By Frank Thorsberg,
Earthworms are a boon to the backyard gardener and healers still use leeches to thin a sick patient's blood, but no good has ever come from a computer worm or virus. Computer viruses have become increasingly dangerous and quick-spreading in the last couple of years, wildly proliferating through cyberspace and causing billions of dollars in damage.
Some of the distinctions between different types of malicious code are now blurred, but the classic computer virus is a piece of sneaky code that tells your PC to do something that you usually wouldn't want it to do. Without your knowledge, a virus could wipe out the programs and data on your hard drive or even let someone take over your machine remotely. A virus replicates by embedding itself into programs or system files.
Worms are another type of devious program that, today, typically spread via e-mail or Internet chat programs. With the help of unprotected users' address books, worms such as Klez spread explosively--disrupting networks and businesses. The oldest worms didn't change system files or obliterate data. But as worms got more sophisticated, the newer ones started to behave more like viruses, doing considerable damage. For example, Klez can delete files and create the mechanism to run itself on system startup.
A third general classification of malevolent code is the Trojan horse. This destructive program poses as an innocent application or file, such as a screen saver or photo. Unlike worms and viruses, Trojan horses don't replicate.
Some viruses and worms won't destroy your data, while others do tremendous damage. For example, the LoveLetter virus overwrote files and inserted viral code on hard drives around the globe two years ago.
"As far as what [virus writers] can do, the sky is the limit," says April Goostree, virus manager for McAfee.com. "In the antivirus industry, we never say 'never' anymore. Because as soon as you do, you are going to be proven wrong. It's anybody's guess about what the next virus will do."
Here's a look at ten of the most malignant viruses and worms of all time.
10. Surreptitious Sircam
Sircam appeared in July 2001 on PCs running Windows 95, 98, and Me. The worm appeared in e-mail in-boxes with an attachment; the body of the message was in Spanish or English. Typical greetings included "Hi! How are you?" and "Hola como estas?" If you launched the attachment, Sircam installed itself on the infected computer, then grabbed random documents and sent them out to e-mail addresses it captured from your address book. It also occasionally deleted files and filled the infected computer's hard drive with gibberish. Visit Symantec's Security Response for instructions on how to remove Sircam.
9. Red Raider
Code Red burned brightly in the summer of 2001, infecting hundreds of thousands of computers--mainly on corporate networks. Code Red slithered through a hole in Internet Information Server (IIS) software, which is widely used to power Internet servers, then scanned the Internet for vulnerable systems to infect and continue the process. The worm used contaminated PCs as weapons in denial of service attacks--flooding a Web site with a barrage of information requests. The original target was the official White House Web site, but government officials changed the site's IP address to thwart the attack.
The worm exploited a weakness in the IIS software (which has since been fixed with a patch from Microsoft) that allowed an intruder to run arbitrary code on a victimized computer. Multiple variants of this worm now exist. Visit Symantec's Security Response for instructions on how to protect your system from Code Red.
8. Bad Benjamin
Benjamin--a new breed of worm--was let loose in May 2002, and it affected users of the popular file-sharing program Kazaa. The crafty worm posed as popular music and movie files. Kazaa users thought they were downloading a media file to their machines, but they got the imposter instead. It then set up a Kazaa share folder and stuffed it with copies of itself posing as popular music and movie files, which other Kazaa users would download. It congested the system's network connection and would ultimately fill up a hard drive. Visit Symantec's Security Response for instructions on how to remove Benjamin.
7. Numbing Nimda
Nimda (also known as the Concept Virus) appeared in September 2001, attacking tens of thousands of servers and hundreds of thousands of PCs. The worm modified Web documents and executable files, then created numerous copies of itself. The worm spread as an embedded attachment in an HTML e-mail message that would execute as soon as the recipient opened the message (unlike the typical attached virus that requires manual launching of the attachment). It also moved via server-to-server Web traffic, infected shared hard drives on networks, and downloaded itself to users browsing Web pages hosted on infected servers. Nimda soon inspired a crowd of imitators that followed the same pattern. Visit Symantec's Security Response for the Nimda removal tool.
6. Tennis Anyone?
The Anna Kournikova (or VBS.SST@mm) worm, appearing in February 2001, didn't cause data loss, although in the process of boosting the profile of its namesake, the Russian tennis player, it did cause embarrassment and disruption for many personal and business users. The worm showed up in Microsoft Outlook users' e-mail in-boxes with an attachment (supposedly a picture of Kournikova). The attachment proved hard to resist. The result? Clicking the bogus attachment sent copies of the worm via e-mail to all addresses found in the victim's Outlook address book. Kournikova also brought about a number of copycat variants. Visit Symantec's Security Response for instructions on how to remove Kournikova.
Most worm creators have never been identified, but a 21-year-old Dutchman, Jan de Wit, admitted to unleashing this worm. The admitted virus writer is appealing a 150-hour community service sentence handed down in September 2001 by a judge in the Netherlands.
5. (Expletive Deleted) Explorer
The Explorer.zip worm appeared in the summer of 1999, following in the footsteps of Melissa. The worm deleted Word, Excel, and PowerPoint files and randomly altered other types of files. Like Melissa (see below), Explorer traveled via e-mails that appeared to be from someone the recipient knew. The message included a file that, if activated, showed a fake error message to the user. Unlike Melissa, this virus did not use Outlook to gather e-mail addresses. Instead, it watched the in-box of the infected computer and then sent automatic replies to senders, using the same e-mail subject as the original message.
4. Maniacal Magistr
Magistr is one of the most complex viruses to hit the Internet. Its victims, users of Outlook Express, were hooked by an infected e-mail attachment. The virus, discovered in mid-March 2001, sent garbled messages to everyone in the infected user's e-mail address book. Attached were files pulled at random from the infected PC's hard drive plus an executable file with the Magistr code. This virus was not as widespread as many others, but it was very destructive. Magistr overwrites hard drives and erases CMOS and the flashable BIOS, preventing systems from booting. It also contained antidebugging features, making it hard to detect and destroy. Visit Symantec's Security Response for instructions on how to remove Magistr.
3. Malevolent Melissa
The Melissa virus swamped corporate networks with a tidal wave of e-mail messages in March 1999. Through Microsoft Outlook, when a user opened an e-mail message containing an infected Word attachment, the virus was sent to the first 50 names in the user's address book. The e-mail fooled many recipients because it bore the name of someone the recipient knew and referred to a document they had allegedly requested.
So much e-mail traffic was generated so quickly that companies like Intel and Microsoft had to turn off their e-mail servers. The Melissa virus was the first virus capable of hopping from one machine to another on its own. And it's another good example of a virus with multiple variants. Visit Symantec's Security Response for instructions on how to remove Melissa.
2. Klez the Conquerer
The Klez worm, which blends different virus traits, was first detected in October 2001. Klez distributes itself like a virus, but sometimes acts like a worm, other times like a Trojan horse. Klez isn't as destructive as other worms, but it is widespread, hard to exterminate--and still active. In fact, so far, no other virus has stayed in circulation quite like Klez. It spreads via open networks and e-mail--regardless of the e-mail program you use. Klez sometimes masquerades as a worm-removal tool. It may corrupt files and disable antivirus products. It pilfers data from a victim's e-mail address book, mixing and matching new senders and recipients for a new round of infection. Visit Symantec's Security Response for instructions on how to remove Klez.
1. Love Hurts
LoveLetter is the worm everyone learned to hate in spring 2000. The infection affected millions of computers and caused more damage than any other computer virus to date. Users were infected via e-mail, through Internet chat systems, and through other shared file systems. The worm sent copies of itself via Microsoft Outlook's address book entries. The mail included an executable file attachment with the e-mail subject line, "ILOVEYOU." The worm had the ability to overwrite several types of files, including .gif and .jpg files. It modified the Internet Explorer start page and changed Registry keys. It also moved other files and hid MP3 files on affected systems. Visit Symantec's Security Response for instructions on how to remove LoveLetter.
Your Best Defense
The best defense against virus attacks is a good offense. Without proper protection, computer worms can spread like wildfire. From minor annoyances to major epidemics meant to cripple giant Web sites, these tenacious trespassers cost us billions of dollars. Here are several tips to help you keep these troublemakers at bay.
1. Don't open any e-mail attachments that look suspicious or come from unknown senders. Be on the lookout for e-mails from people you know, but with language or style they wouldn't normally use--this should raise a red flag.
2. Install an antivirus program such as Symantec's Norton AntiVirus or McAfee's VirusScan. Take the time to install your vendor's updates on your PC.
3. Go to Symantec Security Response and McAfee.com Virus Information for the companies' latest security alerts, disinfecting instructions, and archives.
4. Stay on top of patches created by other software vendors to thwart new threats and programming vulnerabilities. By registering your software after purchase, you'll be notified by the maker when updates are available. Make sure you review and install the necessary critical updates and fixes available through Windows Update.
5. Visit other expert sites to keep up to date on virus news. Carnegie Mellon University's CERT Coordination Center is a great place to find out about the latest virus alerts and vulnerabilities. The organization publishes many statistics and offers security advice for Web site operators.

Facebook Privacy Policy
Facebook Privacy Policy
Facebook has come under serious fire regarding their privacy policy and the sharing of personal information with advertisers to generate revenue. These things have led to several changed to the social networking giant’s privacy stance, and while many are still skeptical, it seems that the changes are designed to ensure that your personal information stays that way. The former privacy policy was a bunch of law jargon that your average user could never understand. The new policy page, however, utilized FAQs and a simplified language to convey their position on user privacy and the steps they are taking to ensure it.
The Collection of Information
No parent wants their children subjected to endless advertisements designed to tug at their innocence. Facebook collects information on its users regarding interests and hobbies and offers that information up to advertisers for big paydays. If advertisers are getting their hands on the information, who else is accessing it? However, Facebook states that they strongly recommend parental oversight in the information their children are sharing on the internet.
The Sharing of Information
Facebook’s privacy stance offers you the ability to make a profile completely private, however, when you’re teen is posting on a site that isn’t private, the information is viewable by anyone. Due to this dilemma, there is never a truly safe and private haven when considering the use of a social networking site. Predators are crafty, and despite Facebook’s best efforts, they can find a way to your children if you rely only on the site’s privacy policies.
Public Domain
There is a certain element of privacy that everyone is entitled to. However, when one posts things on the internet, not even the best of security standards can protect you. If people are having their identities stolen when using secure credit card processing sites, imagine how easy it can be to access information through a social networking site.
Voluntarily Access
It’s also very important to understand that regardless of Facebook’s Privacy Policy, your child may give their information away by simply “friending” people that they don’t know. When this happens, the dangers can be at an all-time high. Once someone is a part of your child’s friend list, they can access pictures, employment locations, school locations, and anything else they offer up. Any of this information will be used by an online predator to gain the upper hand on your child.
Facebook has done a reasonable job of attempting to protect their users’ privacy. However, like any website, there are no guarantees. The only way to ensure that your children’s private information is kept safe is explaining why they shouldn’t post it at all. This ensures that regardless of a predator’s tactics, they will not be able to show up at school or work to meet your child face to face. Eliminating the threat of this meeting can make a huge difference when considering the safety of y our child. Facebook is a part of everyday life and many parents have embraced it. Just be sure that you’ve familiarized yourself with the Privacy Policy and have explained the dangers to your children.

Jenayah maya tanpa sempadan
Jenayah maya tanpa sempadan
MENYEDARI dunia Internet adalah suatu alam terbuka untuk mereka yang mahu merebut peluang menjadi kaya, seorang lelaki warganegara Switzerland tidak mahu ketinggalan mengambil kesempatan itu.
Tambah menyeronokkan hati peguam berusia 40-an itu adalah apabila berkenalan dengan seorang lelaki dari Malaysia melalui sebuah laman sosial. Dia teruja kerana menganggap pencariannya bakal membuahkan hasil lumayan.
Lelaki yang ditemui melalui jaringan maya itu memperkenalkan diri sebagai seorang ahli perniagaan yang menjalankan bisnes eksport bahan-bahan mentah penternakan dan memiliki syarikat yang berpangkalan di Malaysia.
Peguam itu ditawarkan sebuah kontrak perniagaan mengeksport bekalan makanan ayam ke Hong Kong, tetapi diminta membayar sejumlah wang terlebih dahulu bagi memastikan kontrak tersebut tidak terlepas ke tangan orang.
Teruja dengan tawaran yang tidak disangka-sangka itu, peguam itu menurut sahaja kemahuan 'ahli perniagaan' itu. Wang sejumlah RM1,360,079.50 pun telah dipindahkan ke dalam akaun lelaki tersebut.
Begitupun, oleh kerana tiada apa-apa yang berlaku dalam tempoh masa yang terlalu panjang, dia yang mempunyai latar belakang undang-undang itu telah melakukan penyiasatan sendiri terhadap syarikat tersebut dengan maklumat yang ada.
Luluh hatinya apabila mendapati syarikat tersebut palsu dan tidak pernah wujud di Malaysia. Tidak mahu si penipu siber itu terlepas begitu sahaja, dia telah melaporkan kes itu kepada pihak berkuasa.
Mujur tindakan pantas pihak polis telah berjaya menangkap dua individu, seorang lelaki dan wanita berhubung kes tersebut. Itu merupakan salah satu kes jenayah siber di negara ini.
Pada 15 Jun lalu, negara digemparkan pula dengan serangan alam siber yang ditunjangi penggodam antarabangsa. Dikenali sebagai Anonymous menerusi Operation Malaysia, kesan buruk penggodamannya amat serius.
Dalam serangan tersebut, sebanyak 91 buah laman web telah mengalami gangguan perkhidmatan.
Terdedah ancaman
Kegiatan jenayah dan salah laku siber tidak hanya melumpuhkan laman web, malah sesiapa sahaja boleh terdedah kepada ancaman tanpa sempadan itu.
Ia terbukti apabila CyberSecurity Malaysia melalui Pusat Bantuan Cyber999 telah mencatatkan sebanyak 14,157 insiden keselamatan siber yang dilaporkan oleh pengguna Internet di seluruh Malaysia dari bulan Januari sehingga November 2011.
Jumlah tersebut menunjukkan berlaku peningkatan mendadak sebanyak 97 peratus berbanding tempoh yang sama pada tahun lalu.
Mengikut istilahnya, jenayah siber merujuk kepada perbuatan atau insiden yang dilakukan di alam siber, sama ada menggunakan komputer mahupun peralatan seperti perkakasan dan perisian telekomunikasi.
"Ia dilakukan dengan menggunakan telefon pintar atau peranti teknologi maklumat dan komunikasi (ICT), dengan teknologi Internet digunakan sebagai perantara dan tidak melibatkan perbuatan jenayah secara fizikal.
"Sebagai contoh, penjenayah ini menceroboh maklumat organisasi atau individu, harta intelektual, penipuan kad kredit, kecurian identiti, penggodaman ke atas sistem rangkaian komputer dan laman web organisasi mahupun individu," kata Ketua Pegawai Eksekutif CyberSecurity Malaysia, Lt. Kol. (Bersara) Prof. Datuk Husin Jazri ketika ditemui Kosmo!.
Husin menjelaskan, setiap aktiviti jenayah siber yang dilakukan mempunyai motif atau tujuan tersendiri seperti membalas dendam, marah, berhibur sekadar suka-suka, kewangan dan politik.
Di kebanyakan negara, landskap jenayah siber yang berlaku kesemuanya hampir sama.
Laporan insiden
Di negara ini, CyberSecurity Malaysia mengklasifikasi kategori jenayah atau ancaman siber berdasarkan data laporan insiden keselamatan siber melalui penggunaan Internet yang dikumpulkan Pusat Bantuan Cyber999.
PENIPUAN melibatkan kad kredit juga merupakan salah satu kaedah yang digunakan oleh penjenayah siber.
Statistik yang dikumpul melalui pusat bantuan tersebut dikenali sebagai insiden keselamatan siber, dan tidak dikategorikan sebagai jenayah siber.
Antara insiden keselamatan siber yang dikenal pasti adalah seperti penipuan, spam, pencerobohan, kod berbahaya, cubaan pencerobohan, gangguan siber, laporan kerentanan (vulnerabilities), gangguan perkhidmatan (DoS) dan juga berkaitan kandungan.
Husin memberitahu, terdapat beberapa punca atau sebab berlakunya peningkatan insiden tersebut. Antaranya adalah jumlah pengguna Internet yang semakin bertambah dari semasa ke semasa dan kurang pengetahuan mengenai kepentingan keselamatan siber.
Pusat Bantuan Cyber999 juga banyak menerima laporan insiden keselamatan Internet berkaitan penggunaan media sosial.
"Ada dalam kalangan pengguna Internet yang kurang arif dan juga kurang berhati-hati sewaktu melayari Internet," ujar beliau.
Justeru, peluang tersebut memudahkan lagi penjenayah siber untuk mengambil kesempatan ke atas mereka.
Selain daripada itu, terdapat juga peningkatan ancaman-ancaman penggodaman seperti pencacatan laman web (web defacement) dan juga pencerobohan.
Kelemahan utama yang menjadi sasaran kebanyakan penjenayah siber ialah pihak yang menggunakan penyelesaian sekuriti tidak asli dan yang luput tarikh sah.
Menurut Pengarah Saluran Jualan Kaspersky Lab Asia Tenggara, Jimmy Fong, dalam satu kenyataan akhbar, pengguna peranti teknologi seperti komputer, telefon pintar, tablet dan peranti lain, ia seumpama seseorang yang meninggalkan pintu dan tingkap rumah dalam keadaan terbuka.
"Dalam situasi perbandingan tersebut, pengguna seolah-olah berharap tiada sesiapa yang akan masuk ke dalam rumah seterusnya menyalah guna atau mencuri hak miliknya.
"Di dalam kes ini, ia melibatkan data dan identiti anda," katanya.
