Be Careful When Scanning Unknown QR Codes

ByEmily Dolloff

QR codes, those square, blocky codes you scan with your iPhone’s camera to load a Web page, have become ubiquitous. So much so that we seldom pause before scanning any QR code we see. But if you think about it, that’s the same as clicking random links in emails or texts, which is a terrible idea from a security perspective. “Quishing” (QR code phishing) isn’t commonplace yet, but some sources say there are thousands of cases per month. To avoid falling victim to a quishing scam, only scan QR codes from trusted sources, try to verify what a code will do once scanned, and evaluate the yellow URL preview Safari provides (when using other browsers, all you see is Open in Browser Name). Finally, always install iOS security updates promptly because they often address vulnerabilities that could be exploited with malicious data.

Social Media: QR codes—those blocky squares you scan with your iPhone camera—are an easy way to open a Web page. Unfortunately, scammers also use them to trick people into visiting malicious websites, so read our tip about scanning these codes safely.

    It’s easy to assume your backup app—whether it’s Time Machine, Carbon Copy Cloner, Backblaze, Retrospect, or something else—is quietly doing its job. But…

  • Droids, Drones, Scooters, Cars and USB C

    I remember only a couple years ago when drones were new and cutting edge technology. Now, there are huge sections of the show devoted to drones of all sorts: fighting drones, mini drones, paper airplane drones and dancing drones. I don’t know if it is the Star Wars influence but droids were everywhere, including “laundroids” for folding your laundry, grill cleaning droids, window washing droids and all kinds of robots.

    3D printers were new and unique and again whole sections of the show were devoted to “replicators” making everything from iPhone cases to clothing to spare body parts. Several companies were there just to show their filaments for these 3D printers.

    Scooters were everywhere. You know, the ones in the news that have the batteries that blow up. Well, literally dozens of companies were showing their versions and the original Segway had a booth, too. Some one-wheel scooters were there as well as shoes with wheels that zipped you around.

    Self-driving cars and technology for self driving cars dominated the North Hall and some concept cars were shown, too. My favorite was the Faraday electric car that looked like a single seat batmobile.

    USB-C made its debut at the show with hubs, cables and some USB display port displays, too. I think we will see a lot of USB-C stuff coming up!

    Less prevalent this year was the huge variety of iPhone and iPad cases. There were huge sections last time but while there were several companies showing cases it was toned way down. In their place, power banks of all sorts were being shown in every imaginable shape and size. The Apple battery case, aka the hump, was universally panned but several companies had slim battery cases for the iPhone.

    I did walk through the TV section but it was not as notable as in past years. The 3D fad has sort of expired and 4K displays are common. I still love the OLED displays, though.

    Other areas that were huge were health care and fitness with a lot of wearable fitness devices and health monitors or all sorts from implantable blood glucose devices to blood pressure cuffs, thermometers and scales. The home automation section was larger than previous years and there were some new HomeKit compatible devices. I liked the NoLok offering of bluetooth compatible padlocks and bike locks that work similar to the Kevo system.

    It was a quick trip out to Vegas but it was certainly worthwhile. I will follow up next week with a bit more.
