The threat landscape became a mixed environment shared by viruses, worms and Trojans—hence the name "malware" as an umbrella term for malicious software.
One of the most serious epidemics of this new era was the LoveLetter, which appeared on May 4, As Securelist notes, it followed the pattern of earlier email viruses of the time, but unlike the macro viruses that had dominated the threat landscape since , it didn't take the form of an infected Word document, but arrived as a VBS file. It was simple and straightforward, and since users hadn't learned to be suspicious of unsolicited emails, it worked.
Since the message often came to new victims from someone familiar, they were more likely to open it, making ILOVEYOU a proof-of-concept for the effectiveness of social engineering. The Code Red worm was a "file less" worm—it existed only in memory and made no attempt to infect files on the system.
Taking advantage of a flaw in the Microsoft Internet Information Server, the fast-replicating worm wreaked havoc by manipulating the protocols that allow computers to communicate and spread globally in just hours. Eventually, as noted in Scientific American , compromised machines were used to launch a distributed denial of service attack on the Whitehouse.
One of the most recent of the major viruses came out in , Heartbleed burst onto the scene and put servers across the Internet at risk. Common symptoms included high fevers, coughing and shortness of breath. A total of 8, people worldwide became sick, with only eight of those cases being in the U. The U.

The list of foods linked to salmonella ranged from cantaloupe, peanut butter, raw chicken to even pet food. In , cases of Salmonella linked to small turtles led to a total of cases in 43 states but no deaths reported.
The most recent outbreaks have been reported from consumption of a specific brand of tahini in Stuxnet is easily the scariest virus on the list as it was built by government engineers in the US with the intention of obstructing nukes from being built in Iran.
Stuxnet spread by a USB thumb drive and targeted software controlling a facility in Iran that held uranium. Stuxnet is the first real venture into cyberwar and it definitely asks the question as to what will come next.
So there you have it: while viruses and malware might seem like a myth drummed up by tech companies, they are a very real threat that have caused billions in damage. Sort: Most Recent Reviews.
