A new threat to computer security has been discovered in which tab browsing vulnerabilities are exploited to fool users into divulging passwords and other sensitive information. Dubbed as “tabnabbing”, the vulnerability was discovered by Aza Raskin, the creative lead for the Mozilla’s Firefox browser and co-founder of Songza, a music search engine and jukebox. Tabnabbing fools users into entering passwords and other sensitive information when an unselected tab in your browser appears to transform itself into a lookalike for a familiar website. You are then prompted you to re-enter a username and password, which in turn passes that information along to the hacker. Incidentally, Raskin’s blog post on the topic ( http://www.azarask.in/blog/post/a-new-type-of-phishing-attack/ ) demonstrates how the website can “change” into a lookalike. Both Mozilla Firefox and Google are vulnerable to this type of attack, which is classified as “phishing” – a scam where users are tricked into entering login information into fraudulent websites masquerading as legitimate ones. Fortunately, there have been no instances – yet – in which tabnabbing has been used in phishing attacks, but Raskin says that he is “aware of other researchers and toolkits extending and expanding tabnabbing”. However, it’s very likely that phishers will be looking for ways to exploit tabnabbing soon, and are currently no fixes or patches released. One way you can protect yourself from tabnabbing is to make sure that your browser has the proper anti-phishing features installed. It’s also important that your website is updated with the latest security features since many phishers like to exploit websites running old version web software, which they use to host phishing sites.

Security firm Symantec has uncovered a scheme to extort website owners for money or face the possibility of a DDoS attack. Security firm Symantec recently uncovered a scheme that purportedly attempts to extort money from website owners and operators in order to avoid the possibility of a DDoS attack. The capability of these extortionists to actually carry out the threat is still an open question, and it’s more likely that this may simply be an empty threat to try to get money. The best action against these types of messages is employing screens to block such email from reaching your mailboxes. However, it’s best to seek the services of an expert to determine the extent of risk, and also to employ safeguards and response measures should an attack take place. If you find such messages in your mail, let us know and we can help.

Before you entrust your sensitive data to a “cloud” service provider, make sure you weigh the risks with the benefits. “ Cloud computing ,” largely synonymous with Internet-based computing, has become a hot topic of discussion among many in the business community, with its promise of radically simplifying the access to, and use of, computing resources on demand. It’s no wonder then that it’s been small businesses, often without full-time IT resources of their own, that have been the first to adopt the concept. As a business owner, however, before you start moving critical data to the “cloud,” you’ll do well to bear in mind the risks that come with the computing model. First is security and privacy—ask how the service provider ensures the confidentiality and integrity of your data while in their care. Do they provide backups? Can you back up your data yourself? Are their security processes and procedures reviewed and vetted by a third party? Next is availability. Do they guarantee the uptime of their services—7 days a week, 24 hours a day? Do they provide a service level guarantee? Do they have processes in place to handle exceptional circumstances that can disrupt services, such as a natural disaster? Is support readily available to help in case you encounter any issues? Finally, there’s cost. While pay-as-you go can be attractive, the total cost over time can add up. It’s worth thinking two to three years out and considering the total cost versus alternatives. Asking these basic questions can go a long way in giving you peace of mind before you entrust your valuable data and core business systems to the care of others. If you’d like some help sorting all this out and making the best decision for your unique needs, give us a call.

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. As always, users are advised to be constantly on guard and to make sure they are using the latest updated versions of their software. Customers under our Managed Security program benefit by letting us do the worrying and updating for them, so they can focus on their business instead of their security.

A critical vulnerability in Windows XP has been revealed that involves the Windows and Help support center, a Web-based feature providing technical support information to end users. The vulnerability can potentially allow a remote hacker to take complete control of a victim’s machine. Systems running Windows XP and Windows Server 2003 using many major browsers, including Internet Explorer 8, are affected. A few days after the advisory, security firm Sophos warned users of a website using the vulnerability to install malicious software on victims’ machines, and of possibly more exploits coming out soon. Users of Windows XP and Windows Server 2003 are advised to disable features within Help Center that allow administrators to remotely log onto their machines. For individual users, Microsoft has released a patch for the flaw. Don’t know how to install the patch? Need help? Let us know! Of course our customers with Managed Services are automatically advised of these vulnerabilities, and patches are applied as soon as they are available. Contact us today to find our more.

A recent report , released by Osterman Research and sponsored by software vendor Commtouch, reports that the incidents of outbound spam is getting worse. The research firm interviewed 266 end users of internet service providers and 100 web hosting companies. Almost 40% of respondents have had their IP addresses listed on Real Time Blackhole Lists (RBLs) in the past 12 months alone – and the number could be far greater considering those who may not be aware that they have been listed. RBLs tag machines or networks of machines as being sources of SPAM, causing their emails to be filtered out by many mail servers. This can result in legitimate emails not reaching their intended destination, and can victims’ reputations. In addition, having an infected machine or network of machines can waste bandwidth and slow down outbound connections. The cause of outbound spam varies, but can including everything from compromised email accounts to “zombie” machines – machines infected with malware sending out spam unbeknownst to the user. There are multiple ways of protecting computers and networks against the risk of outbound spam, and our Managed Services clients benefit from our proactive protection and filtering.

The average computer and Internet user manages over a dozen passwords for various websites. You probably have passwords for your computer, your company email, your personal online email accounts, your favorite social networking websites, your twitter feed, your online bank account, your favorite online store, and more. Using the same password for everything is not very secure, but keeping track of unique passwords for each can be a pain.
