الذي يكتب برنامج خبيثة ولما?

حمى كاتبات: أربعة أنواع عامّة

حمى ينتسب كاتبات إلى واحدة من أربعة مجموعة واسعة: [سبر-فندلس], الذي يستطيع كنت قسمت داخل اثنان أصناف, وأكثر مبرمجات جدّيّة, الذي يستطيع ثانية كنت انقسمت داخل اثنان مجموعة.
[سبر] تخريب - مرحلة 1

في الماض, كتبت كثير [ملور] كان بمبرمجات شابّة: جديات الذي فقط كان قد علم أن يبرمج الذي أراد أن يختبر مهاراتهم. لحسن الحظّ لم ينشر أكثر من هذا برنامج على نحو واسع - الأغلبية من هذا [ملور] يمات عندما أسطوانات كان [رفورمتّد] أو حسنت. لم يكتب حميات مثل هذا كان مع هدف مادّيّة أو هدف محدّدة, غير أنّ ببساطة للكاتبات أن يؤكّدبنفسي.

[سبر] تخريب - مرحلة 2

كان الثاني مجموعة كبيرة مساهمات إلى [ملور] [كدينغ] الناس شابّة, عادة طالبات. علم هم كان بعد يبرمج, غير أنّ تلقّى سابقا جعل قرار واعية أن يكرّس مهاراتهم إلى حمى كتابة. هذا كانوا الناس الذي كان قد اختار أن يعطّل ال [كمبوت كمّونيتي] ب يرتكب أعمال من [سبر] [هووليغنيسم] و [سبر] تخريب. كان حميات يؤلّف بأعضاء من هذا مجموعة عادة جدّا بدائيّ والرمز احتوى [ا لرج نومبر وف] أخطاء.

مهما, زوّد التطوير من الإنترنت فراغ وفرص جديدة ل هذا مدّعية حمى كاتبات. يتعدّد [سبرينغ وب] موقعات, ثرثرة غرف وأخرى موردات حيث أيّ شخص استطاع علمت حول حمى كتابة: ب يتحدّث إلى يمهر مؤلفات ويجلب كلّ شيء من أدوات ل يبني ويخفي [ملور] إلى خبيثة برنامج [سورس كد].

محترفة حمى كاتبات

وبعد ذلك هذا' نص نما [كيدّيس]' فوق. لسوء الحظّ, لم ينمو بعض من هم من حمى كتابة. بدلا من ذلك, فتّش هم [كمّرسل بّليكأيشن] لمواهبهم ملتبسة. يبقى هذا مجموعة ال أكثر كتومة وقسم خطرة من الحاسوب باطنيّة: هم قد خلقوا شبكة من محترفة ومبرمجات موهوبة الذي يكون جدّا جدّيّة حول كتابة و [سبردينغ] حميات.

محترفة حمى يكتب كاتبات غالبا رمز إبداعيّة يصمد أن يخترق حاسوبات وشبك; هم يبحثون برمجيّة وجهاز جروحية ويستعمل هندسة اجتماعيّة في طرق أصليّة أن يضمن أنّ سيبقى أخلاقهم خبيثة ليس فحسب, غير أنّ أيضا ينشر على نحو واسع.
حمى باحثات: ال `[برووف-وف-كنسبت]' [ملور] مؤلفات

الرابعة ومجموعة صغيرة من حمى كاتبات بالأحرى نادرة. هذا حمى يدعوبنفسي كاتبات باحثات, وهم غالبا مبرمجات موهوبة الذي يكرّس مهاراتهم إلى يطوّر طرق جديدة ل يخترق ويعدي نظامات, يخدع [أنتيفيروس] برامج [أند س فورث]. هم عادة بين الأولى أن يخترق جديدة [أبرت سستم] وجهاز. ومع ذلك, هذا حمى لا يكتب كاتبات حميات لمال, غير أنّ لبحث أغراض. They usually do not spread the source code of their ‘proof of concept viruses’, but do actively discuss their innovations on Internet resources devoted to virus writing.

All of this may sound innocent or even beneficial. However, a virus remains a virus and research into new threats should be conducted by people devoted to curing the disease, not by amateurs who take no responsibility for the results of their research. Many proof of concept viruses can turn into serious threats once the professional virus writers gain access to them, since virus writing is a source of income for this group.

Why write viruses?

Fraud

The computer underground has realised that paid for Internet services, such as Internet access, email and web hosting, provides new opportunities for illegal activity with the additional satisfaction of getting something for nothing. Virus writers have authored a range of Trojans which steal login information and passwords to gain free access to other users’ Internet resources.

The first password stealing Trojans appeared in 1997: the aim was to gain access to AOL. By 1998 similar Trojans appeared for all other major Internet service providers. Trojans stealing log in data for dial-up ISPs, AOL and other Internet services are usually written by people with limited means to support their Internet habit, or by people who do not accept that Internet resources are a commercial service just like any other, and must therefore be paid for.

For a long time, this group of Trojans constituted a significant portion of the daily ‘catch’ for antivirus companies worldwide. Today, the numbers are decreasing in proportion to the decreasing cost of Internet access.

Computer games and software license keys are another target for cyber fraud. Once again, Trojans providing free access to these resources are written by and for people with limited financial resources. Some hacking and cracking utilities are also written by so-called ‘freedom fighters’, who proclaim that all infomration should be shared freely throughout the computing community. However, fraud remains a crime, no matter how noble the aim is made out to be.
Organised cyber crime

The most dangerous virus writers are individuals and groups who have turned professional. These people either extract money directly from end users (either by theft or by fraud) or use zombie machines to earn money in other ways, such as creating and selling a spamming platform, or organizing DoS attacks, with the aim here being blackmail.

Most of today’s serious outbreaks are caused by professional virus writers who organize the blanket installations of Trojans to victim machines. This may be done by using worms, links to infected sites or other Trojans.
Bot networks

Currently, virus writers either work for particular spammers or sell their wares to the highest bidder. Today, one standard procedure is for virus writers to create bot networks, i.e. networks of zombie computer infected with identical malicious code. In the case of networks used as spamming platforms, a Trojan proxy server will penetrate the victim machines. These networks number from a thousand to tens of thousands of infected machines. The virus writers then sell these networks to the highest bidder in the computer underground.

Such networks are generally used as spamming platforms. Hacker utilities can be used to ensure that these networks run efficiently; malicious software is installed without the knowledge or consent of the user, adware programs can be camoflaged to prevent detection and deletion, and antivirus software may be attacked.
Financial gain

Apart from servicing spam and adware, professional virus writers also create Tojan spies which they use to steal money from e-wallets, Pay Pal accounts and/or directly from Internet bank accounts. These Trojans harvest banking and payment information from local machines or even corporate servers and then forward it to the master.
Cyber extortion

The third major form of contemporary cyber crime is extortion or Internet rackets. Usually, virus writers create a network of zombie machines capable of conducting an organized DoS attack. Then they blackmail companies by threatening to conduct a DoS attack against the corporate website. Popular targets include estores, banking and gambling sites, i.e. companies whose revenues are generated directly by their on-line presence.
Other malware

Virus writers and hackers also ensure that adware, dialers, utilities that redirect browsers to pay-to-view sites and other types of unwanted software function efficiently. Such programs can generate profits for the computer underground, so it’s in the interests of virus writers and hackers to make sure that these programs are not detected and are regularly updated.

In spite of the media attention given to young virus writers who manage to cause a global epidemic, approximately 90% of malicious code is written by the professionals. Although all of four groups of virus writers challenge computer security, the group which poses a serious, and growing threat is the community of professional virus writers who sell their services.

Virus writers belong to one of four broad groups: cyber-vandals, who can be divided into two categories, and more serious programmers, who can again be split into two groups.
Cyber vandalism - stage 1

In the past, most malware was written by young programmers: kids who just had learned to program who wanted to test their skills. Fortunately most of these programs did not spread widely - the majority of such malware died when disks were reformatted or upgraded. Viruses like these were not written with a concrete aim or a definite target, but simply for the writers to assert themselves.

Cyber vandalism - stage 2

The second largest group of contributors to malware coding were young people, usually students. They were still learning programming, but had already made a conscious decision to devote their skills to virus writing. These were people who had chosen to disrupt the computing community by committing acts of cyber hooliganism and cyber vandalism. Viruses authored by members of this group were usually extremely primitive and the code contained a large number of errors.

However, the development of the Internet provided space and new opportunities for these would-be virus writers.Numerous sites, chat rooms and other resources sprang up where anyone could learn about virus writing: by talking to experienced authors and downloading everything from tools for constructing and concealing malware to malicious program source code.
Professional virus writers

And then these ’script kiddies’ grew up. Unfortunately, some of them did not grow out of virus writing. Instead, they looked for commercial applications for their dubious talents. This group remains the most secretive and dangerous section of the computer underground: they have created a network of professional and talented programmers who are very serious about writing and spreading viruses.

Professional virus writers often write innovative code designed to penetrate computers and networks; they research software and hardware vulnerabilities and use social engineering in original ways to ensure that their malicious creations will not only survive, but also spread widely.
Virus researchers: the ‘proof-of-concept’ malware authors

The fourth and smallest group of virus writers is rather unusual. These virus writers call themselves researchers, and they are often talented programmers who devote their skills to developing new methods for penetrating and infecting systems, fooling antivirus programs and so forth. They are usually among the first to penetrate new operating systems and hardware. Nevertheless, these virus writers are not writing viruses for money, but for research purposes. They usually do not spread the source code of their ‘proof of concept viruses’, but do actively discuss their innovations on Internet resources devoted to virus writing.

All of this may sound innocent or even beneficial. However, a virus remains a virus and research into new threats should be conducted by people devoted to curing the disease, not by amateurs who take no responsibility for the results of their research. Many proof of concept viruses can turn into serious threats once the professional virus writers gain access to them, since virus writing is a source of income for this group.
