New Viruses Infiltrate Systems through USB Drives

Two new viruses have been discovered to infiltrate systems through removable drives. USB flash drives have become indispensable to almost everyone who uses a computer. It’s a quick and easy way to immediately transfer and share information and other data, especially files that are too large to send through email. Unfortunately, some malware take advantage of this convenience by attaching themselves to files on the drive to infect any other system it comes into contact with. Two such malware have recently been discovered. Chymine is a Trojan application with keylogging capabilities, designed to copy passwords and other sensitive data, and Dulkis-A is a Visual Basic worm designed to copy and allow malware to infiltrate the system. Both exploit a vulnerability in Windows Shell. Microsoft has yet to directly address the issue and provide a patch that fixes the problem. In the meantime, they have issued directions for a workaround that prevents both malware from manipulating the Windows Shell susceptibility. The workaround is effective for Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server R2, but it comes with a cost – you lose all your icon graphics. Success in removing the virus has been marginal at best, with current fixes including a warning that removing these malware might result in unwanted changes to your system because of the way the virus embeds itself. The best way to avoid being infected, be careful not to run any suspicious programs and files, especially when taken from USB drives and any other removable storage, even from a Blackberry or an iPhone. It’s also best to avoid automatically enabling USB devices to autorun once they’re plugged into your computer.

Increasing Adoption of Mobile Devices Presents Opportunity for Businesses

Despite the clear trend towards greater adoption of mobile devices by businesses and consumers, a new study finds that many businesses are not taking full advantage of the opportunities created by this trend—especially in sales and marketing. Global smartphone shipments continue to rise, driven by operator subsidies, lower barriers to adoption with the introduction of lower-cost models, and greater choices afforded by vigorous competition from companies such as Apple, RIM, Microsoft, and Google. Not far behind is the rising interest and adoption of other mobile devices, such as tablets with the success of Apple’s iPad. Despite this trend, a new study by eROI , an online marketing agency, finds that many businesses are not taking full advantage of the opportunities it creates—especially in sales and marketing. The company surveyed 500 businesses, and the majority cited lack of resources and little understanding of what needs to be done as the major barriers to capitalizing on the trend. This, despite findings which show 91 percent of the population use mobile devices, with 23 percent using smartphones that make extensive use of online services. Companies would benefit from looking at how these trends can be leveraged for building a strategy toward reaching new customers, engaging current customers, and creating rich experiences for both. Some examples from early pioneers in this area: building versions of their website that can be viewed comfortably on mobile devices, using services that make extensive use of social networks and location-based services such as Facebook and FourSquare that work well with mobile devices, and even building custom applications to provide a new channel for reaching and serving customers. Companies can start small with pilot projects then work from there to see which work best for their businesses.

Common Vulnerabilities in Many Common Applications Still Exploited by Hackers

The continued exploit of many vulnerable applications that have been fixed by vendors for over a year highlight the need to keep software updated with the latest versions and patches. A new report released by security firm M86 Security reveals a trend toward more sophisticated forms of malware in taking advantage of vulnerabilities in common software applications and developing techniques to avoid detection. In M86’s report, among the applications commonly exploited are Microsoft’s Internet Explorer and Adobe Reader. Another vector for malware that hackers have been using recently is Java and Adobe’s Flash—which are installed on many PCs, often as plug-ins to most browsers. Although the vulnerabilities in these applications have been identified and patched for over a year, failure to keep up with the latest updates have made many systems still vulnerable to attack. Our customers taking advantage of our Managed Security need not worry, since we make sure our customers’ systems are patched as soon as updates become available.

Mozilla Firefox Releases Fixes for Several Major Security Holes

Mozilla implements new initiatives to ensure the security of its browser to fix the main security holes, and this brings Firefox’s latest version to 3.6.7 The Mozilla foundation, the organization behind the Firefox browser, announced recently that it has released a patch to fix many major security holes found in its software, as well as the pull out of malicious add-ons in its extensions gallery. A new update brings Firefox’s latest version to 3.6.7, and includes fixes for nine critical issues that could potentially be exploited by hackers to launch attacks on vulnerable systems. This comes after recently pulling out a password stealing add-on called the “Mozilla Sniffer” in the Firefox extensions gallery. As a preventive measure, the Mozilla foundation has announced a US $3,000 security bounty program that for anyone who finds an eligible security bug. It has also announced that it will implement a source code review of add-ons to catch potential malware that could be injected into otherwise patched Firefox browsers.

Smart Mobile Management

With mobile devices becoming a staple in business dealings these days, it’s high time companies enact policies for mobiles that will not only help them cut costs, but keep their information and data safe as well. Experts outline several tips to help you achieve this. In this day and age, it’s a necessity to always be in touch, and many mobile phones are now equipped with features to help us do just that, such as internet connectivity, SMS, push email, and more. With this increase in the use of smart phones such as Blackberries and iPhones for work, it follows that maintenance costs of mobiles can get to be pretty steep if not managed correctly. Bills for one mobile phone can reach more than $2,000 a year – just imagine the maintenance costs for several units. In addition, the need for more rigid and concrete policies for mobile devices is also increasing. Experts recommend that since many of the functions of mobile devices mimic those of a desktop workstation, companies should apply the same policies they have for their IT systems to their mobile devices. Such a policy not only reduces costs, but will also keep your entire system safe. Since sensitive information is now stored on mobiles, there’s the risk of infiltration and information theft – and for many companies with little or no protection for the mobile arm of their system, it’s only a matter of time before they find themselves in trouble. Here are some tips from the experts: Use an integrated management system for both your office IT infrastructure and your company’s mobile devices. There are plenty of reputable providers for this kind of software, with big names such as Nokia and Microsoft offering programs that cater to multiple phone manufacturers. Minimize the frequency and access of personal mobile devices to your IT system at the office. More often than not, personal mobile devices do not have the same safeguards as that of office equipment, and allowing them to connect to your system poses a number of risks. Authorize your IT group to remotely access company mobile devices. In case a unit is lost or stolen, any or all information on it can be wiped clean.

Windows XP Users Targeted by Zero-Day Exploit

Barely a month after a Google engineer disclosed a critical vulnerability in Windows XP, hackers have taken launched an attack on vulnerable machines. On June 10, a Google engineer disclosed a security flaw in Windows XP’s Help Center, which can potentially allow hackers to search and retrieve sensitive information from vulnerable PCs, and even turn them into “zombies:”machines that follow the commands of a remote master to perhaps download more malware or send out spam. Recently, reports have come out that the first real exploit has emerged, with Microsoft reporting that over 10,000 Windows XP systems have already been subjected to attack . The systems attacked are based not only in the US, but also in Russia, Portugal, Germany, and Brazil. A patch from Microsoft was released on July 13, and workarounds also exist to contain the threat, such as disabling the HCP protocol. Customers of our Managed Security services running Windows XP are assured of immediate support once the patch is rolled out, but in the meantime can take advantage of our assistance to secure systems through other means. If you’re on one of our Managed Services plans don’t worry – you’re protected. If you’re not sure contact us to find out how we can protect your systems and network from this and other dangerous attacks.

Lessons Learned from the World Cup

The recent fever over the FIFA World Cup made unsuspecting victims an easy target for malware makers, spammes, and scammers using the sport as a means to spread nefarious software or lure users into money-making scams. It seems the entire world was in the grip of the 2010 FIFA World Cup fever as several countries vied for football supremacy in South Africa. Unfortunately, malware makers, spammers, and scammers capitalized on the fever as well, using references to the event as a means to spread nefarious software or lure unsuspecting users into money-making scams. Some of the threats included 419-style scams , lures selling fake tickets, even fake products and business opportunities related to the World Cup. One particular ploy involved a couple of websites selling a bogus filter to cancel out the sound of noisy “Vuvuzela” trumpets in TV broadcasts. Scammers had even used legitimate websites to sell them—such as eBay and other auction sites. Several spammers used sophisticated techniques to confuse SPAM filters by using tools to automatically scrape the text from hundreds of websites (including news sites) and using them to spray random bits of this text into their messages. Another new development that was seen were targeted attacks on top executives of international manufacturing companies and government agencies. With the 2010 World Cup behind us, what does this mean to us now? Everyone should always be on guard against websites, links, or messages that seem too good to be true (because most likely they are), but understanding that scammers and spammers especially thrive during popular events helps everyone to be on extra high alert.

Preventing Data Loss With Managed Services

Implementing a client-server network and maintaining it with Managed Services can help small to medium-sized businesses prevent data loss events, which lead 43 percent of such businesses to close within two years. According to DriveSavers data recovery service, 43 percent of companies that lose data in a disaster never reopen, and 90 percent are out of business within two years. How can you prevent data loss—without the hassle and expense of staying on top of the latest technology and continually monitoring backups? Consider a client-server network combined with Managed Services. With client-server networks, computers and other devices called clients are connected to a centralized computer called a server. The server stores information in a central location, and shares it with the clients on the network. Why is this a better setup for data loss prevention than the traditional peer-to-peer network, in which computers are connected directly to other computers? First, because peer-to-peer networks have no centralized security safeguards, anyone connected to the network can gain access to all of the devices on the network, making it easy to lose data through malicious acts by hackers and viruses. Second, because peer-to-peer networks don’t share information in a centralized location, if one device on the network fails, all the data stored on that device is lost. This makes it easy to lose data through hardware and software failures. With a client-server network, you address both of these potential problems. Security software can be installed centrally, ensuring that everyone on the network has the most up-to-date protection. At the same time, access to data that might be lost through malicious acts can be controlled, with different access levels given to different users. It’s also easy to back up (and retrieve, if necessary) data because it’s stored in a centralized location. The only remaining problem is that maintaining a client-server network requires you to stay on top of the latest technology, monitor backups, and troubleshoot problems—and that can take the resources of a dedicated IT staff. If you don’t have such an IT staff, or if you’d prefer your IT staff to work on revenue-producing projects, you may want to consider Managed Services. With Managed Services, an IT company monitors your network to ensure security is high and data is backed up regularly. If a problem occurs, it’s addressed quickly, with data retored almost before you know it’s missing. The best news: Your support costs should be approximately the same as if you were paying to address problems as they arise—but your network’s safety will be significantly higher.

Work from Any Place at Any Time

Work no longer has to be a place your employees go at a certain time. Learn what technologies can enable your employees to get more done from any location, any time. Lately there has been a trend among companies, no matter what size and maturity, toward the use of so-called “virtual” teams. Driven perhaps by rising office and energy costs, maturity of computing and network technologies, talent scarcity, or simply the opportunity to realize increased efficiency, this has resulted in the adoption of flexible work arrangements for some employees including flexible time and working from home – or even from remote locations in different time zones. Along with this trend has come the need to support this new way of working. A wealth of options exists—from virtual team spaces and online collaborative tools to more advanced communication devices such as smartphones and tablets. Here are a few examples. For teams working at the same time but from different locations: Conferencing applications—via telephone or video Shared workspaces and whiteboards Instant messaging Wireless communication devices For teams working at different times but in the same place: Team rooms Intranets For teams working at different times and from different places: Extranets Virtual Private Networks E-mail/Groupware Message boards Blogs and knowledgebase tools With the right tools, work can happen any time and from any place.
