How threats spread
As modern computer technology and communications tools develop, hackers
have more opportunities for spreading threats. Let‟s take a closer look at them:
The Internet
The Internet
is unique, since it is no one‟s property and has no
geographical borders. In many ways, this has promoted the development
of web resources and the exchange of information. Today, anyone can
access data on the Internet or create their own webpage.
However, these very features of the worldwide web give hackers the
ability to commit crimes on the Internet, and makes the hackers difficult to
detect and punish.
Hackers place viruses and other malicious programs on Internet sites and
disguise them as useful freeware. In addition, scripts which are run
automatically when certain web pages are loaded, may perform hostile
actions on your computer by modifying the system registry, retrieving your
personal data without your consent, and installing malicious software.
By using network technologies, hackers can attack remote PCs and
company servers. Such attacks may result in a resource being disabled or
used as part of a zombie network, and in full access being gained to a
resource and any information residing on it.
Lastly, since it became possible to use credit cards and e-money through
the Internet in online stores, auctions, and bank homepages, online
scams have become increasingly common.
