ritchie58 Posted May 26, 2011 Report Share Posted May 26, 2011 How many viruses are made by anti-virus companies? A commentary by Christian Mairoll, CEO of Emsisoft Background As CEO of an anti-virus company my friends and associates often ask me "Who writes all these viruses?" and hidden behind this question is the sometimes serious accusation that "You write them yourself, just to drum up business!". If it was only so simple... The reality is however very different. Apart from the fact that this would be morally reprehensible and also illegal, it is actually pretty easy to prove that it is technically impossible for the anti-virus companies to manufacture the sheer volume of viruses produced. Cost/Benefit calculation The currently produced Viruses, Trojans and Bots are the result of an enormous amount of programming work. Intentionally and unintentionally released source code only allows a rough estimate of the original effort required but one can easily assume that every new genus of Malware is the result of at least 1-3 months of programming work. New variants that are further developments of old Malware are of course easier to produce. At Emsisoft, we add around 20,000 new Malware signatures (fingerprints) to our detection database every day, i.e. roughly half a million each month. Historical developments indicate that the number of new threats doubles each year. Emsisoft Anti-Malware currently has 5.5 million signatures in its database. This also includes many signatures that detect variants of the same Malware using generic detection, so the total number of signatures is less than the actual number of Malware programs. If I was the CEO of an evil anti-virus company I would first need a new employee to write a Virus in the first place. I would also need someone for further development and maintenance to protect my investment by ensuring that the Virus will still run on future operating systems. Once the Virus is finally finished it would then released into the wild and entered into the detection database of our own Antivirus software. Great! In only one month we have managed to build one new Virus - one single Virus among 500,000 others in this month. By now, it should be clear to everyone that it simply makes no commercial sense for us to write the Viruses ourselves. The advantages obtained through detection of one extra piece of Malware against the sheer unbelievable volume released each month are simply too small. Even when the cost of hiring programmers in dumping-wage countries is very low, it is absolutely certain that no Antivirus manufacturer can afford to do this. Even all the Antivirus manufacturers in the world together would not be able to generate the current volume of new Malware. Well, who then is writing all this new Malware? Sorry to say but it seems that these are people who can earn much more money writing Malware than the Antivirus sector could ever earn by writing their own Malware. 10 years ago these programs were mostly written by hackers wanting to test the realms of what was possible, but these days an enormous amount of criminal energy and hard-core commercial enterprise lies behind most Malware. A centrally controlled network of several thousand kidnapped PCs (Botnet) can be used in variety of different ways. This massive amount of computer power can be hired as a package for various devious purposes: For sending Spam and Phishing emails, for coordinated webserver overload attacks (DDos) in order to blackmail companies or as a proxy server network for hiding the traces of illegal activities. The largest detected Botnets such as Conficker, Rustock or Cutwail had over a million such "Zombie" computers available. Other Malware authors attempt to convert their work directly into hard cash by encrypting important personal information and then demanding ransom money for decrypting the data (so-called Ransomware). Some Malware is directly targeted at specific companies or systems, for instance the sabotage attacks on the Iranian atomic energy program using the Stuxnet Malware at the end of 2010. Antivirus = Virus Another reason for the rumor that Antivirus companies write the Viruses is the increase in the number of fake Antivirus products (so-called Rogue Antivirus software). The authors of this type of Malware use names that are similar to well-known Antivirus brands to trick users into installing software that only pretends to detect Viruses. Forged detections are then used to urge the customer to purchase a "Full version". Conclusion As you can see, Malware authors have many incentives to write new damaging software. All these incentives have one thing in common: They offer much greater rewards than the Antivirus companies could expect from writing their own Viruses. Quite apart from the fact that only one public example of this type of activity would be a legal, commercial and media disaster for an Antivirus manufacturer. There is also the argument that Antivirus companies depend on the work of the Malware authors. This may be true, but our intentions lie at the opposite end of the moral spectrum and we are always doing our best to make the Internet a safer place. Have a nice (Malware-free) day!
