Online security is not a new issue in 2011. Last year businesses witnessed an incredible rise in malware attacks and phishing scams. Although security firms work tirelessly to undermine online criminals, hackers too work around the clock to introduce novel and variant schemes that security tools are not yet equipped to prevent. And so as businesses benefit from the greatest antivirus products to date, they still face constantly updated methods of attack as well as new threats to their personal information.
That is why it is absolutely necessary to utilize common sense and constant vigilance when working online in 2011, but in order to do so you will need to be supplied with helpful information on what you should be looking out for. Below is a comprehensive list of the greatest online threats in 2011 coupled with advice on how to protect your crucial business data as we now realize that security products won’t always be enough.
Threat # 1: Web apps
In 2010 businesses the world over turned to two new technological advances: smartphones and cloud computing. As mobile phones and cloud computing optimize employee productivity it is no surprise that these two business technologies are on the rise. It is also no surprise that as a result web applications are a new target for cybercriminals. According to a recent study conducted by the Pew Internet and American Life Project, 85% of US adults own a mobile device. According to that same study on March 1, 2011 it was found that more than 50 apps on Google’s Android Market had been compromised by the Trojan virus DroidDream. When you run DroidDream believing it to be a web app for your smartphone, the Trojan automatically assumes total administrator access over your device and proceeds to download more malicious content as well as steal your personal information.
How do you protect yourself? Proactively protecting yourself from malware-infected web apps isn’t exactly easy. Although Google caught onto DroidDream, wiped the malicious false apps from their Market, and remotely removed the apps from client devices, new ones will continue to crop up and will typically only spotted in hindsight. If you wish to incorporate smartphones, cloud computing and web apps into your business plan, be sure to implement common sense protection procedures. Enforce password policies for maximum password protection, device locking, remote wiping, and hardware and data encryption.
Also, be sure to read reputable reviews on apps before purchasing them and only download apps that come from known and vouched for sources. You can even purchase antivirus web apps for your mobile device. Another security precaution would be to read an app’s permissions screen carefully before downloading which discuss the information the app will be allowed to access on your device and uncheck any undesirable permissions to information.
Threat # 2: Social networking scams
Just as the use of web apps and related attacks are on the rise, social networking is also a growing trend among businesses. According to research conducted by BitDefender last November, 20% of all Facebook users are currently susceptible to malware attacks, the most common of which are phishing scams. A phishing scam is any attempt to fool a user into visiting a malicious site parading as a trusted social network site, typically Facebook. This sort of attack will more often than not come from a trusted Facebook Friend (a Friend who has already been compromised by the scam) in the form of a malicious link that can infect your PC and steal your personal data including your Facebook login information (thus increasing the reach of the scam as the hackers will now utilize your Friend list to further spread the malicious content).
Another social networking scam is the use of false, malicious applications on sites such as Facebook. Just like the phishing scams, these apps will also steal your personal information from your social networking sites. While it does not seem like these sites contain critical personal information such as social security or bank account numbers, they do often contain your date of birth, location of birth, cellular phone number and email address – all of which can be gathered to build a profile that could result in identity theft.
How do you protect yourself? First, know what suspicious behavior to look out for. Hazardous apps, for example, typically wish to post on our wall and access your Friend lists. You should ask yourself why an app would desire these permissions. Usually it is for malicious purposes. If you have already downloaded a hazardous app do not worry: very often saving your information is as simple as revoking the app in your security permissions and changing your account password. Also be wary of any invitations to view photos or videos on social networking sites. If that sort of activity does not seem to fit the sender’s online behavioral patterns you should probably not click on the link.
Also, be cautious of any link a site is trying to prompt you to follow to information concerning other social network scams - such as recent Twitter scams that you have never heard of prior to the link invitation. Hackers are beginning to use scare tactics to get you to click on links to purported security information or program downloads that are in fact malware. This leads us into Threat # 3.
Threat # 3: False antivirus downloads
According to a report conducted in 2010 by Sophos, there have been over 850,000 instances of antivirus scams in the past year. This sort of attack is also known as scareware, as the malware utilizes relevant scare tactics concerning the recent distress over the prevalence of malware and convinces victims to download free antivirus software. Sometimes the scam stops there, with the victim downloading malware onto their personal computer. Other times the scam continues with the malware claiming that your computer is threatened by a virus and in order to save your device you must download a full version of the program, thus giving away your credit card information and identity to a cyber criminal.
How do you protect yourself? You must utilize a current and reputable antivirus program such as those offered by McAfee to protect yourself from fake antivirus downloads. And be sure to never download an antivirus program online from a pop-up window or from a third-party site!
Threat # 4: PDF email attachments
Malicious email attachments are the oldest of online attacks and they are still prevalent in 2011, with PDF documents generating the greatest amount of occurrences, according to a 2010 report from Symantec. This is due to the fact that PDFs are the easiest way in which a hacker can create seemingly legitimate, concealed malicious content. According to MessageLabs, 65% of all email-based malware attacks utilized PDF attachments and the projection for 2011 is that this number will climb to 76%.
How do you protect yourself? Obviously you want to incorporate an antivirus and spam filtering device into your security plan. Also, use common sense. Never open email attachments that you were not expecting or that you do not know the author of and keep your PDF reader up-to-date (Adobe for example regularly releases security updates). Also note that the new Adobe Reader X has an updated security architecture that will better protect you from PDF attachment attacks.
Threat # 5: War games
According to Perimeter E-Security, war games are on the rise in 2011: everything from state-sponsored malware attacks, industrial espionage, and hactivism.
How do you protect yourself? Monitor your network traffic for suspicious activity and regularly review employee data access policies; these security measures will help you to protect yourself from both external as well as internal security threats.
