Galaxy S10 Fingerprint Lock Can Unlock with any Finger

A British woman has discovered that a simple screen protector can defeat the ultrasonic fingerprint scanner on the Galaxy S10.

Because of the way the Galaxy S10 reads fingerprints, a simple screen protector can be enough to defeat the security. While Samsung touts their scanning method as more secure, it’s actually been thwarted multiple times so far. The first time, it was undone with a $450 3D printer. This time, the exploit seems to be more serious.

This is far from the first time Samsung security has been called into question. In 2017, the Galaxy S8 facial recognition feature was hacked with a photo. The vulnerability, one which had been common to all facial recognition, was solved by other companies more than 5 years earlier.

Though all of the previous exploits were problematic, they needed planning. You can’t 3D print a fingerprint or print a photo of a person unless you know them. This exploit is far simpler and more serious. Almost everyone keeps a screen protector or case on their phone to prevent damage.

If keeping a screen protector on your Galaxy S10 is all that it takes to let anyone unlock it with their finger, no one’s phone will be secure. Samsung needs to address this vulnerability as soon as possible. This sort of issue could well kill enthusiasm for the phone.

Scam Calls: Fake Virus or Support Calls, and Why They’re Dangerous.

Image of a hooded figure on a black background with lines of computer code floating around them. Scam calls and why they're dangerous.
Scam callers can be dangerous to more just than your bank account.

These days, one seems to get more scam calls than real ones. Car warranty calls, health insurance calls, even fake creditors. It’s so frustrating. This is especially true when strangers call you about your computer. A reputable company will never call you out of the blue to warn you of an issue. Any cold caller who tells you that you need to pay them money, or worse, allow them access to your computer does not have your best interests in mind. It takes vigilance to protect yourself from scam calls.

Viruses and trojans are a concern for any internet connected PC. Most people with malware infections, however, find out by running a local virus scan. Unless you are paying someone to monitor your antivirus, no one will call you to warn you of an infection. If a stranger calls you about it, it’s most likely a scam call.

It’s not just your money at risk.

While most scammers who call to tell you your computer has been hacked are after money, some are even more insidious. Access to your computer can provide a dishonest person with more than the money you pay them. They can see all of your files, install malicious software, or even copy your passwords. A particularly sneaky scammer can do a lot of damage.

Think about the sorts of information you type in to your browser on a regular basis. Banking information. Names. Addresses. At tax time, your Social Security number. Although your computer is usually safe behind your router or firewall, allowing a scammer to access it lets them past all lines of defense.

Your antivirus software, firewall, home network and router all work together to protect you. They’re like the immune system protecting your information from attack. When you allow a stranger into your computer via a screen sharing or remote access program, it’s like stabbing a knife straight through all the layers of protection. It’s much easier to infect the computer from the inside, just like it’s much more likely for a cut to get infected than your skin.

What should you do if a scammer calls you? Contact us! We will be happy to help repair the damage to your computer. We’ll even evaluate your protection and help you be safer in the future. After 15 years in the repair business, we know a thing or two about how to keep you safe.

Windows 7 End of Support:

Why should you upgrade?

Microsoft Windows 7 Logo
Say goodbye to your old OS.

Though it was groundbreaking at release, Windows 7 is reaching its end of life. Support has slowly been tapering off on certain computers already, and will end completely as of January 14th, 2020. No more feature updates will be released. Security updates will be released through the end of the support cycle, but not after that.

Once support for an operating system like Windows 7 ends, it becomes much more vulnerable to viruses, malware, and errors. When Microsoft is no longer supporting it, the unsupported software — very much like an out of warranty appliance — becomes much more difficult to maintain and repair. Although very little is likely to change for you day-to-day, any issues with your operating system could cause you to lose your data – everyone’s worst nightmare!

If your computer is older than 2015, it most likely has Windows 7 installed. If you want to know whether you need to upgrade, what it will cost, or just don’t want to install it yourself, Cherry Tree Technology is here to help.

Contact us 24 hours a day! We’d love to help with the upgrade of your operating system or even your whole computer. We have been helping Tucson and the surrounding areas take care of their computers and electronics since 2004. We’d love to add you to our family of clients.
