Use Wi-Fi? Your Device Is at Risk in the Latest Security Breach

Another day, another way our personal data is being compromised. This time, the latest threat to your credit card numbers, social security information, and other personal data comes from a more-than-ubiquitous source: your Wi-Fi.

As Ars Technica and The Independent report, a computer security researcher has discovered a major issue with Wi-Fi that can be used to decrypt your data. The vulnerability is the result of weakness in the WPA2 protocol that secures modern Wi-Fi networks. Hackers can steal sensitive data that has been decrypted using a method called KRACK, or Key Reinstallation Attacks. While we can't know yet if hackers have actually taken advantage of the vulnerability, its existence puts every Wi-Fi-enabled device at risk.

“If your device supports Wi-Fi, it is most likely affected,” Mathy Vanhoef, the Belgium-based researcher who discovered the exploit, said. That means your phone, your computer, and even your Wi-Fi light bulbs. The hacker only needs to be within range of your Wi-Fi—not logged into your network—to take advantage of it and steal your data. However, Ars Technica reports that Android and Linux users are more vulnerable to severe attacks than Windows or iOS users.

What should I do to protect myself?

Unfortunately, changing your passwords won’t help this time around. All you can do is wait for security updates for your devices. In the meantime, treat every Wi-Fi connection like it’s the public network at Starbucks. As in, don’t go sharing all your personal data. You can make yourself safer by using a VPN. According to cybersecurity expert Robert Graham, these kind of attacks can’t defeat VPNs.

Most companies will no doubt be releasing security patches to fix this issue ASAP, so keep a look out for any available updates.

What the Color Codes on Toothpaste Tubes Really Mean

Packaging details—like the circles on chip bags and the symbols on cosmetics labels—can be mystifying to the average consumer. For years, a graphic has circulated the internet claiming to explain the hidden meaning behind the colored markings on the bottom of toothpaste tubes. While it's true that those color codes are there for a reason, the reason is much less interesting than the online rumors suggest.

According to Snopes, a widely-shared image on social media alleges that the colors on the seams of toothpaste tubes correlate to certain types of ingredients. The picture shows four different colored markings, with green meaning natural, blue indicating natural and medicine, red meaning natural and chemical composition, and black signifying pure chemical.

This "decoding" isn't based in truth, however. The markings on toothpaste packaging have nothing to do with the ingredients inside the tube—and even if they did, classifications like natural and chemical are too vague to mean anything. The real reason the colors are there is to aid the machinery responsible for putting the packaging together. The tiny colored rectangles are actually called eye marks or color marks, and they tell light beam sensors where a tube needs to be cut or folded. Once the toothpaste reaches the store, the markings no longer serve a purpose.

If you do want to know more about the ingredients in your toothpaste, it's not as hard as deciphering a mysterious code. "Oral care companies don’t mark their toothpastes with colored squares to try to trick consumers and hide ingredients from them," Colgate writes on its website. "If you want to know what kind of ingredients your toothpaste has, don’t look for a colored block at the end of the tube. Instead, take a look at the packaging for a comprehensive list of ingredients."

You can find the ingredients in your toothpaste listed on the outer box and/or the tube itself—and you don't need to know any secret codes to read them.
