The Dangers of Public Wi-Fi
The convenience and practicality of using public Wi-Fi hotspots is undeniable, but it can also be a problem should hackers decide to exploit network loopholes and gain access to the people connected to it. It’s important to have the proper protection to keep your system safe. These days, Wi-Fi is everywhere. Airports, coffee shops, train and bus stations, malls – almost every public place you can think offers Wi-Fi connectivity. Being connected to the internet has evolved from luxury to necessity, and whether it’s for personal or business reasons people are online as much as possible. This is all well and good, except when you consider that hackers have started to extend their playing field to public Wi-Fi networks. With the volume of sensitive information such as passwords and financial transactions, it’s inevitable that crooks and fraudsters move to public networks where there is more potential to illegally farm large chunks of information. Two things are important about this emerging trend. First, it’s the very nature of public networks that makes them vulnerable to attack. Second, hacking has become much easier these days, with very simple hacking programs such as Firesheep easily downloadable from the web. However, the solution is simple as well: have the proper security protocols on your smartphone or laptop. It’s unfortunate that many people neglect to recognize the importance of such policies, and only have minimal security (if any at all) to guard against attacks. But as long as you have the proper protocols in place, you can stay connected – even through public Wi-Fi – without fear of hacking or any sort of intrusion into your system. If you want to know more about keeping your portable devices safe from attacks, please feel free to contact us. We’ll be glad to explain the issue in more detail and draw up a solution customized to fit your needs.

Many IT service providers are learning valuable lessons from the Epsilon incident – which saw one of the world’s biggest email service providers become a victim of cyber-criminals, compromising a substantial amount of information entrusted to them by their clients. There’s been a lot of buzz recently about Epsilon, one of the biggest email service providers in the world, as it suffers from the backlash of allowing itself to be a victim of phishing efforts – which has affected the business data of as many as 50 major companies who are clients of theirs. Reports are also citing Epsilon’s failure to heed an alert from a business partner which advised the provider to be on its toes against potential attacks from cyber-criminals targeted towards email service providers. The damage estimates vary, with Epsilon citing only about 2% of their data being stolen, but the impact is undeniable. Cyber-criminals now have access to a sizable number of personal data stored through Epsilon – passwords, account numbers, and even the purchasing / buying habits of the customers of Epsilonงs clients. Many of Epsilon’s clients are now sending out messages to their own customers, warning them that their email addresses may have been compromised. It’s a lesson to companies, big and small, to pay more attention to beefing up their security protocols, since all it takes is one breach to endanger all of your data. In addition to having the right security software, it also helps if you require your employees undergo proper user training to make sure that they won’t be easily baited by scams like phishing, and will be more aware of how to contribute to the safety of your business data. Failing to do so puts not only your company, but also your clients, at risk. If you’d like to make sure your systems are safe, call us and we’ll evaluate your current security measures and suggest ways to make critical improvements.
Continue readingHR Managers Must Think About Data Security, Too
Employees have access to a wide variety of electronic information, from the moderately important (such as email lists) to the critical (such as financial records and trade secrets). Upon their departure, HR managers should work with IT to ensure that employee account access is blocked. Remember the days when employees kept important information in paper files? They are long gone. According to a study conducted by the University of California at Berkeley, almost all of today’s new information is stored electronically. And that could mean trouble for your company when an employee resigns — because electronic documents are both easy to copy, and portable. That makes them more prone to theft than paper documents. Case in point: In August 2009, DuPont filed a lawsuit against a research scientist who allegedly stole more than 600 files by copying them to a portable hard drive. And that wasn’t an isolated incident; another DuPont research scientist was sentenced to an 18 month prison term for stealing proprietary information worth $400 million. Think employee data theft doesn’t apply to your type of business? Think again. A 2009 study conducted by the Ponemon Institute found that data theft is rampant in the business world. According to the study, 59 percent of employees who quit or are fired take confidential business information with them. And when the employee works in IT, the access to confidential data is even greater. A 2008 study by Cyber-Ark Software found that almost 90 percent of IT employees would take sensitive company data with them if they were laid off. The lesson: When employees leave, you must take steps to protect the electronic information they have access to. This may include customer information, financial records, trade secrets, intellectual property, and email lists, to name just a few items. We recommend that when an employee leaves, you prevent his or her account access, set the account for immediate review, save any necessary files (which may involve consulting with other departments for verification of documents), then delete the account. In addition to protecting data, this will also optimize server space and open up more storage space for the company. While some employees might argue that they need access to their personal files before departing, and you may grant such access (supervised, on a case-by-case basis), it is not required; any of the information that is located on a company computer is company property. In a sensitive situation it’s always good to let us know ahead of time so we can help you prepare for a well-managed and secure transition.
Continue readingEmail Encryption: Why It’s Important
When we create a letter in the analog world, we take the time to seal that letter in an envelope to keep it safe from prying eyes — especially if that letter contains sensitive information. If it’s highly confidential information we might even resort to obfuscation such as using coded text, or making sure that it is delivered via secure channels such as by special messenger. Encrypting email is relatively easy with today’s software. Usually it involves the use of a public key and a private key. The public key is available to everyone, and if you want to send someone an email message you would use that person’s public key to encrypt that message. That person in turn would use his private key, to which only he has access, to decode that message. Software such as the latest versions of Microsoft Outlook supports this feature , and even flags you if the recipient’s email software does not support encryption. Some systems take it a step further by allowing you to digitally sign your emails, so that other people can verify that it is you who actually sent the email and not someone else. This is especially important since hackers sometimes spoof or impersonate the identities of others to fool unsuspecting users. If you are interested in finding out more about email encryption and security, contact us today to find out how we can help make sure your messages are safe and secure.
Continue readingDon’t be Lazy with Your Passwords
Passwords are more or less the equivalent of keys when it comes to cyberspace. However, passwords can be compromised through hacking, stealing, or even just guessing – which is why password security and integrity is very important. In the same way that keys are used to open different doors, passwords are used to access many areas of cyberspace. However, those passwords are vulnerable to hacking, stealing, or random guessing – which makes password integrity and security a main concern. However, for many people, this essential fact is overlooked. Many tend to use either easy-to-guess passwords, or use the same password for all their online accounts – from their online banking to their email – which is a hacker’s dream come true. Because when they steal a password, it’s standard operating procedure for them to test it against popular websites to see if it works there as well. The most basic security measure you can use to guard against this is to have multiple passwords for your different online accounts – whether they are for personal or business use. And don’t just think of easy passwords, like your birthday or wedding anniversary – these are usually the first thing hackers try. The best passwords are alphanumeric – composed of both letters and numbers so that it’s harder to crack. This might be a bit tedious, but it’s better than running the risk of compromising your security online. There are also several programs and applications you can use to help store your passwords, so you only need to remember a few of your most-used ones, and refer to your database for the others. Remember, your passwords hold the keys to most, if not all, of your online presence, so keeping them secure is extremely important. If you’re looking for a security solution for your passwords, please give us a call so we can help you implement a password security system that works for you.

Continue readingBeware: JavaScript from Unfamiliar Sites May Be an Attack in Disguise
Everyone enjoys having a more interactive internet experience, and one of the ways websites achieve this is through the use of JavaScript. Unfortunately, hackers and scammers can also utilize the same script to make malicious attacks on your system. JavaScript makes the web experience very dynamic, enhancing the interactivity of many websites – you’ll see it everywhere, from Facebook to the most obscure sites on the web. Another reason it’s popular is that it’s compatible with all browsers, from Internet Explorer to Mozilla and even Mac’s Safari. Unfortunately, this popularity and wide range of use also makes JavaScript a tool that hackers and other unscrupulous programmers can use to infiltrate and hack into a system. The attacks can be simple or complicated, ranging from simple spam to more elaborate scams. The degree simply depends on the purpose of the script’s designer. What’s more, a quick visit to an infected website can trigger an attack, if your browser is enabled to allow JavaScript to execute from that site. The good news is that you can protect yourself from these kinds of attacks. Simply block JavaScript from executing from sites you aren’t familiar with – better safe than sorry. For Internet Explorer , go to Tools > Internet Options > Security, and set your bar to High. You can also input a list of trusted sites. For Firefox users, a free application called NoScript gives you control over which websites can execute JavaScript on your browser. Google Chrome users can select a universal disabling of JavaScript from all sites, and then add a list of sites exempted from the ban. Other browsers also have options to either disable JavaScript execution or prompt you for permission before the script is run from any website. You should also be particularly wary of JavaScript attacks originating from malicious PDF files. Antivirus and security firm Symantec reports that almost half of all web-based attacks come from infected PDF files. You can disable JavaScript in Adobe Acrobat Reader by selecting Edit > Preferences > JavaScript, and then removing the check on “Enable Acrobat JavaScript”. It might seem inconvenient to guard yourself from these sorts of attacks, but in the long run it pays to keep your system secure. If you want to know more about keeping your system clean and safe from attacks, give us a call and we’ll be happy to help you develop a customized plan that meets your particular needs.
Continue readingNew Security Threat: Tabnabbing
A new phishing technique has been discovered – tabnabbing “morphs” an unused tab in your browser into a lookalike website where you’re prompted to re-enter login 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. If you want to know more about keeping your system secure from the latest malware and security threats, please don’t hesitate to get in touch with us and we’ll be happy to sit down and discuss security options that fit your needs and requirements.
Continue readingRacket Extorting Money from Website Owners Revealed
A money extortion scheme was revealed recently by security firm Symantec that warns website owners of a DDoS attack unless they pay up. 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.
