Stuxnet, a malicious computer worm, is one such example as malware used for sabotage. Rumoured to be a jointly-built American-Israeli cyber weapon, the worm was used to target specific industrial equipment in efforts to disrupt Iran’s nuclear program.
Worms, like Stuxnet, and viruses are among the best-known examples of malware. A
computer virus is a program which embeds itself in other executable software without the user’s knowledge. When that program is run, the virus replicates by reproducing itself or infecting other programs by modifying them.
A worm, however, is a stand-alone malware program which actively transmits itself over a network to infect other computers. IN short, a worm spreads on its own, whereas a virus needs the user to run an infected program.
The use of malware has grown alongside the growth of the internet. There are, however, tools specifically designed to combat malware. There are many types of anti-virus and anti-malware software, which act as a scanner checking if files are legitimate or not.
Some websites also offer website security scans, while an ‘air gap’ can be used as a last resort. An ‘air gap’ completely disconnects infected computers from other networks and devices – but malware has been known to beat the ‘air gap’ through such means as removable media.
