Viruses and Worms, Protection from Disaster
Virus damage estimated at $55 billion in 2003. "SINGAPORE - Trend Micro Inc, the world's third-largest anti-virus software maker, said Friday that personal computer virus attacks price worldwide firms an estimated $55 billion in damages in 2003, a sum that would rise this year. Organizations lost roughly $20 billion to $30 billion in 2002 from the virus attacks, up from about $13 billion in 2001, in accordance with a variety of sector estimates." This was the story across a large number of news agencies desk January 2004. Out of $55 billion, just how much did it cost your firm? Just how much did it expense a person you know?
I. The Why
There's an average of 10-20 viruses released every day. Really few of these viruses actually make ?Wild? stage. Viruses are designed to reap the benefits of safety flaws in software program or operating systems. These flaws is usually as blatant as Microsoft Windows NetBIOS shares to exploits working with buffer overflows. Buffer overflows happen when an attacker sends responses to a program longer then what's anticipated. If the victim computer software isn't designed properly, then the attacker can overwrite the memory allocated for the software program and execute malicious code.
People today make viruses for numerous motives. These motives variety from political to financial to notoriety to hacking tools to plain malicious intent.
Political: Mydoom is really a very good example of a virus that was spread with a political agenda. The two targets of this virus had been Microsoft and the SCO Group. The SCO Group claims that they own a big portion in the Linux source code threatened to sue every person making use of Linux operating systems (with "stolen" programming supply). The virus was very efficient knocking down SCO's internet site. However, Microsoft had enough time to prepare for the second attack and effectively sidestepped disaster.
Monetary: Some virus writers are hired by other parties to either leach monetary data from a competitor or make the competitor look bad inside the public eye. Industrial espionage is actually a higher risk/high payout field that will land someone in prison for life.
Notoriety: There are some that write viruses for the sole purpose of receiving their name out. This can be good when the virus writers are script kiddies mainly because this aids the authorities track them down. There are numerous renowned viruses that have the author's e-mail in the supply code or open script
Hacking Hackers at times create controlled viruses to help within the access of a remote laptop. They'll add a payload towards the virus like a Trojan horse to enable straightforward access in to the victims program.
Malious: These would be the folks that happen to be the most unsafe. They are the blackhat hackers that code viruses for the sole intention of destroying networks and systems without having prejudice. They get high on seeing the utter destruction of their creation, and are extremely hardly ever script kiddies.
Several with the viruses which might be written and released are viruses altered by script kiddies. These viruses are referred to as generations in the original virus and are extremely seldom altered sufficient to be noticeable from the original. This stems back towards the truth that script kiddies usually do not fully grasp what the original code does and only alters what they recognize (file extension or victim's site). This lack of understanding tends to make script kiddies really dangerous.
