Virus Bull. This paper analyzes virus in a general The paper presents guidelines and procedures framework. A brief history of computer viruses used to maintain virus collection at the university is presented and any presence of threat relevant of Hamburg's Virus Test Center. It examines several specific areas Vesselin Bontchev, "The "Pros" and "Cons" of on vulnerability in research-oriented systems. It Basic for Applications version 5. Since a macro reflects on the degree of responsibility, that an virus written in one language has be antivirus company needs to shoulder, while it automatically converted to another language it is provides its product information to users.

The yet another unique virus. Due to this inherent author has detailed on the tests and procedures feature of MS Office 97, virus researchers have he has used to evaluate Invircible product's to create new virus to prepare an antidote. A side claimed features and proves that the claims are effect of this activity has reportedly been that far from reality. The write-up is old in terms of these upconverts are created and "officially" providing techniques for antivirus software listed as existing in some anti-virus product functionality but is still informative on giving stimulates their creation and distribution by the ideas on designing antivirus software.

The author has given suggested solutions for this problem. Two viral sets of This paper summarizes some ideas that are likely macros can have common subsets or one of the to be used by virus writers in the future and sets could be a subset of the other. The paper suggests the kind of measures that could be taken discusses the problems caused by this. It against them. Anti-Virus Research," Doctoral Thesis, Faculty This paper discusses the ways of attacking one of of Informatics, University of Hamburg, the most powerful methods of virus detection on This thesis is a detailed writing on computer integrity checking programs.

It demonstrates viruses. It can be treated as a definitive text on what can be done against these attacks. The important topics discussed in this David M. It www. Language for VERV. This is the first formal work in the field of computer viruses. It reasons for the availability This paper models complexity based virus of better-equipped crisis teams that may arise detection mechanisms, that detect modifications due to the continued growth of the Internet.

These models are program systems on the Internet have impacted then used to show how to protect information in the trends in virus spread.

The deployment of both trusted and untrusted computing bases, network aware software systems on the Internet show the optimality of these mechanisms, and has contributed positively to the spread of discuss some of their features. The models network-aware virus. The paper briefly lists indicate that we can cover changes at all levels of some generic features of the software, which aid interpretation with a unified mechanism for in virus spread.

The Universal Viral Machine

White, "An unification in some depth. Davida, Yvo G. Desmedt, and Brian J. This paper extends Fred Cohen's demonstration Matt, "Defending Systems Against Viruses on computer Viruses that there is no algorithm through Cryptographic Authentication," that can perfectly detect all possible viruses. This paper describes the use of cryptographic authentication for controlling computer viruses. The A formal definition for computer worms has authentication scheme determines the source and been presented. The definition is based on integrity of an executable, relying on the source Turing's model of computation.

The scheme presented relies on a trusted device, the Fred Cohen, "Computational Aspects of authenticator, used to authenticate and update Computer Viruses," Computers and Security, programs and convert programs between the Vol. In addition, each user's machine It presents a model for defining computer uses a similar device to perform run-time viruses.

It formally defines a class of sets of checking. The authors discuss a dynamic monitoring This paper brought the term "computer viruses" mechanism, comprising of a watchdog system, to general attention. It describes computer which dynamically enforces a security policy.

Tech Time Warp: Fred Cohen’s work leads to the term “virus”

This paper discusses a dynamic monitor called DaMon. Detection Problems to detect vulnerabilities in programs during execution. Since the intended Denning, P. Specifications of Worm incident. This paper gives a brief note on privileged programs in Unix have been how the Internet Worm worked. It also discusses presented, along with a prototype execution the concerns arising due to the worm incident on monitor, to analyze the audit trails with respect the networks on which commerce, transportation, to this specification.

Jeffrey O Kephart and Steve R. Eichin and Jon A. Only a small "Virus. It discusses the in real incidents, partly because many viruses are goals of the teams working on the Virus, and the below the theoretical epidemic threshold. Models methods they employed, and summarizes what of localized software exchange can explain the the virus did and did not actually do. The paper observed sub-exponential rate of viral spread. Kephart, Gregory B. Sorkin, Morton effective and ineffective defenses proposed by Swimmer, and Steve R. White "Blueprint for a the community against it. It discusses the flaws that California, October , were exploited to attack systems and propagate Since the internet will provide a fertile medium across the Internet.

It also enumerates methods for new breeds of computer viruses, the authors of preventing future attacks and problems. Of course, I wanted to examine "the beast" and to understand how exactly it works and why. The problem was, it was already gone! I visited the office in their company, and after a long and fruitless search for an infected file, we finally found a piece of paper in the trash bin, that contained the hex dump of an infected file Then I disassembled it, understood it, wrote my own disinfector and even a vaccine for it This is how it all began for me.

Klaus Brunnstein. I am in charge of maintaining our virus collection. I am also analysing viruses, helping people who are asking virus-related questions from all parts of the world, writing my Ph. Why did you leave Bulgarian anti-virus scene and moved to Germany? Because I was proposed the wonderful opportunity to live and work under excellent working conditions in place with a very high reputation in the computer anti-virus field - and also to get a Ph.

It depends on your definition of "familiar".

It is known that certain animosity existed between you and Bulgarian virus writer known as Dark Avenger some time ago. The same bad things I've been always thinking about him. Sorry, but my education does not allow me to list them here. Most of them are just irresponsible juvenile people I am tempted to say - kids , who want to "establish" themselves and to impress their peers, by doing things that they perfectly know are regarded as "bad" by the society, but for which, as they also know very well, this same society is unlikely to be able to punish them.

They like so much to brag about their "exploits" and "civil liberties", but it is actually the same old graffiti writing, only in a more modern, electronical form. In short - vandals. What do you think about beneficial viruses and artificial life? Why are people willing to reject the concept of beneficial viruses and artificial life in general? I don't feel competent to comment about artificial life, because I am not expert in this area. I don't believe that computer viruses are a form of artificial life, however.

People don't like to even hear about the so-called "beneficial viruses" mostly because the term "computer virus" is already loaded with negative meaning in the public opinion - maybe incorrectly, just like the term "hacker", but that's it how it is. I would suggest to anybody who is doing serious and responsible research in the field of self-replicating code, to use some other term, if they don't want to be misunderstood by the general public. After all, what Dr.
