A vulnerability recently discovered could allow hackers to track your real time movements while using the navigation app known as Waze. It is a community-based traffic and navigation app that is available on most smart phones. While the plus side is it allows drivers to share traffic and road information with one another, the down side is your current location can be tracked.

With some reverse engineering of the app’s communication protocols once the hacker has intercepted the communication between a user’s phone and Waze’s servers, they can issue commands directly to Waze’s servers. They then can create fake traffic jams to reroute users or monitor their every move.

Good news is you’re only vulnerable while you’re in your vehicle and actively running the app on your phone. As a precaution, you may want to consider setting your app to invisible mode so your phone is not broadcasting its information to the app. This will need to be done every time you turn on your phone. It’s recommended that you disable location-sharing on all mobile devices to prevent these types of hacks.

Did you know that Facebook and Twitter have geolocators which can tell people where you are, when you’re there, and where you’ve been? For many, this is an amazing feature and makes tagging your recent vacation photos a breeze. But for some unlucky few, its makes them targets for mischief and sometimes even crime.

By leaving your geotagging on, it can be akin to a big sign on your home advertising to criminals that no one is home, inviting them to break-in. There are ways to disable this feature for Facebook and Twitter, both for all posts, or just specifically on a post-by-post case.

Also, while we as adults may find this to be just another scare tactic, this might be very dangerous for your child as every post may tell a criminal just where your child is at all times.

You may have read the many articles we have posted referencing ransomwares that have been infecting computers worldwide. Well good news is there is a temporary fix so long as the hackers haven’t patched the hole that the solution exploits. A researcher has developed a tool that allows victims infected with the Petya ransomware to unlock their files for free.

The solution may be one where you need a professional to assist you with as the directions are pretty tech heavy and may be too complicated for most users. To quote Lawrence Abrams, a computer security expert at Bleeping Computer: “To use Leostone’s decryption tool you will need attach the Petya affected drive to another computer and extract specific data from it. The data that needs to be extracted is 512-bytes starting at sector 55 (0x37h) with an offset of 0 and the 8 byte nonce from sector 54 (0x36) offset: 33 (0x21). This data then needs to be converted to Base64 encoding and used on the site to generate the key.”

This is why having a proficient and efficient tech company on your side and at the ready is important so you don’t have to spend time finding help when disaster strikes. Contact Optfinity today to see how we can mitigate these problems before they happen.

Just as the title suggests, uninstall QuickTime for Windows immediately! To clarify, this is QuickTime installed on your PC, not your Apple computer. Why? Because Apple is no longer supporting this software for Windows and will no longer be pushing out updates to maintain its safety, security and integrity.

There are two existing vulnerabilities right now with the software which risks your device being hacked or victimized by malware. Additionally, there are no longer good reasons to keep the software as most sites utilize HTML5, a web-standard, for video and audio playback.

This threat is so serious, the US Homeland Security’s Computer Emergency Readiness Team (CERT) has even issued a warning regarding this issue. Those running QuickTime on their Windows machines should click on the “Start” icon, go to “Control Panel” > “Programs” > “Programs and Features,” select “QuickTime Player,” and hit “Uninstall.”

If you still have questions, or are not sure how to complete this process, contact us at Optfinity and we’ll gladly help secure your systems!

Do you or your company have mobile apps? When was the last time you tested it for flaws, holes, or other vulnerabilities? If you haven’t, you’re not alone. Even very large companies such as Dominos have failed this test.

In this article, a security consultant from the UK stumbled upon a pretty big bug in Dominos’ ordering process. Because their payments were processed on the client side instead of the server side, he was able to change the values of the payment codes and pay for his pizza using a fake credit card number.

Not to worry, this computer guru was an honest man and not only notified Dominos, but also paid for his pizza when it arrived. But don’t think all hackers who stumble across a bug in your system will be this magnanimous. So be sure that your website and apps are as infallible as possible by testing them thoroughly. Not sure how to do this or where to start? Then it’s a good time to contact the experts at Optfinity!

Adobe currently has a vulnerability, known as CVE-2016-1019, which could potentially allow hackers to take control of your systems. Rest assured, there is a patch in place which you should download immediately to mitigate the problem. This is also a good time to remind you that you should be constantly downloading and running all updates and patches officially pushed out from the providers themselves. These updates are not just for Windows users, but for Adobe Flash Player for Macintosh, Linux and ChromeOS as well.

If a hacker does manage to exploit your system through this vulnerability, it could open you up to the Cerber ransomware problem we have mentioned before. So if you don’t want to have to pay someone thousands of dollars to get your data back, be sure to update your system, or at the very least enable “Click to Play” which stops Flash from automatically playing unless you specifically give it permission.

We will even do a free assessment so you can know beforehand if you’re vulnerable to dangerous hackers. Click here to read more details in Adobe’s latest security bulletin.

So you’re working hard throughout the day when all of a sudden your computer screen goes blank, turns blue, or just shuts down altogether. If this problem is becoming more frequent than you’d like, consider these 5 tips from this article before going out and buying a new computer.

1) Corrupted System Registry Files: The best way to rule this possibility in or out is by running a Windows registry cleaning program. Such programs scan your Windows registry for problems then automatically make repairs.

2) Disorganized Files: By running a defragmentation once every few months, you may be able to keep those pesky computer crashes at bay.

3) Malicious Software: Download and run malware or adware programs which regularly scan your computer for the presence of these problems and also guard against them. There are many free versions, so consider these before paying for one.

4) Too Little Available Memory: If it appears that your available memory is low, you can use a PC cleanup program to remove unnecessary files; such programs remove things like temporary Internet files and other file debris that can suck away much-needed memory.

5) Overheating: Sometimes, the fan on your computer wears down and doesn’t work as efficiently; other times, it’s just not able to handle the work that your computer has to do. In either case, buying a bigger, better fan isn’t very expensive.

If you’ve gone through all these tips and your computer is still crashing, it may be time for a new computer. Don’t forget that, just like your car, regular care and maintenance from the beginning will help prolong the health and life of your tech gadgets. So don’t wait till there’s a problem before you do many of these tips.
