Top Malware Myths And Facts

27 July, 2016

Over the past few years, computer security has become the primary concern for most people. To stay protected, it is important to know about different types of malware found online i.e. how they spread and the repercussions they may bring. However, there are a myriad of misconceptions about malware that put internet users at risk.

Discussed below are some common myths and facts about malware that you should know to safeguard your computer and protect your information online:

Myth: Updating software is not important for computer security
Fact: A computer with an outdated version of anti-virus software is more susceptible to malware infection. Software vendors frequently release patches and upgrades to protect against the latest security threats. Hence, you must either enable the anti-virus software to update automatically or check for newer versions available on the vendor’s website.

Myth: Malware infection can be easily detected
Fact: Though some types of malware show obvious signs when they infect a computer, such as displaying a pop-up demanding ransom from the user or causing the system to crash. However, certain malware are specifically designed to avoid detection by the user. They may be programmed to stealthily collect sensitive information, send spam emails from the computer or lock down important files.

Myth: Malware only affects Windows
Fact: Though most malware are created to target Windows users, other platforms are not immune from this online threat. With an increasing share of Android and Mac users, hackers are initiating various cross-platform malware to target multiple devices.

Myth: Reputed websites are safe
Fact: While it is partially true that malware mostly spreads by visiting websites that have pornographic or pirated content, credible websites can also be compromised. Hackers use a technique known as malvertizing, which involves placing malicious ads on reputed websites. Clicking on these ads or just visiting the website may download a malware to the user’s computer.

Myth: You are safe if you do not have anything important on your computer
Fact: Even if you have not stored sensitive information on your hard drive, malware can scan other important details that can be used to achieve its goal. For instance, it may access your email account to send out spam emails to your contacts or trace your keystrokes to steal login credentials for online financial transactions. With this information, hackers can cause serious damage including identity theft and phishing attacks.

Spammers Spread Trojan with H1N1 E-Mails

Dec 3, 2009

Several security vendors are reporting a large malware campaign taking advantage of interest in H1N1 vaccinations.

The e-mails claim to link to a Web page for the Centers of Disease Control and Prevention where users can register for a new “State Vaccination H1N1 Program.” However, anyone who clicks on the link ends up with the Zeus Trojan, a prevalent piece of malware used to steal data off of compromised machines.

Security company AppRiver detected the campaign around 8:15 a.m. (CST) Dec. 1, and a hour later was filtering about nearly 18,000 e-mails per minute.

According to Symantec, the domain used in the e-mail links has the format of online.cdc.gov.[RANDOM CHARS].[TLD NAME].im, such as online.cdc.gov.yhnbad.com.im.

“As is usually the case with these campaigns, the URL that is supposed to be a document actually leads to an executable file,” blogged Hon Lau of Symantec. “This one is named vacc_profile.exe and is detected by Symantec as Infostealer.Banker.C. Incidentally, the URL is also ‘personalized’ with the e-mail address of the recipient to make it look that little bit more authentic and less like mass-mailed spam.”

The subject lines of the e-mails vary, but some of the ones that have been observed are “Governmental registration program on the H1N1 vaccination” and “Your personal Vaccination Profile.”

If you have any doubt about the authenticity of the e-mail, don’t click it. Information about H1N1 can be found here on the CDC Website.
