Defending Against Malware and Trojan Horse Threats
Malware – software written to infect private computers and commit crimes
such as fraud and identity theft—has become big business in the cyber
underworld. As a result, if you use a computer for web surfing, shopping,
banking, email, instant messaging, and gaming without proper protection,
you are putting yourself at high risk of being victimized.
By exploiting vulnerabilities in operating systems and browsers, malware
can sneak malicious Trojan horse programs onto unsecured PCs.
Unsuspecting and unprotected users can also download Trojans, thinking
they are legitimate game, music player, movie, and greeting card files.
Trojans can also lurk in files shared between friends, family, and coworkers
using peer-to-peer file sharing networks.
What Do Trojans Do?
Trojans corrupt important files and place adware, spyware, keyloggers, and
screen scrapers that can steal personal information and your online
experience. They can also redirect you to fake phishing web sites—even
when you type valid web addresses (URLs) into your browser.
How Does My PC Get a Trojan?
Today, Trojans can be spread by browser drive-bys, where the program is
downloaded in the background when you simply surf to a rigged web site.
Shell code runs a Trojan that downloads additional payload code over
HTTP—various forms of bots, spyware, back doors, and other Trojan
programs. Hackers then send phishing emails to lure users to web sites,
where unsuspecting victims are tricked into revealing personal information.
Hackers can also exploit security weaknesses on sites, and then piggyback
their Trojans onto legitimate software to be downloaded by trusting
consumers.
Top 10 Ways to Defend Against Malware and Trojans
Although hackers never stop developing new tricks to commit fraud and
steal identities, consumers can take proactive steps to safeguard their
systems. All it takes is a combination of robust security software and a
commitment to following basic safety rules.
