Serious MacOS Bug Allows Anyone to Access Your Computer With a Blank Password

Regular updates are one of the best ways to keep your computer secure, but a glitch in a recent version of macOS High Sierra leaves users seriously vulnerable. As The Guardian reports, anyone can unlock a Mac that has the new software without typing the correct password.

The gaping security hole was first shared in an Apple developer support forum. To take advantage of it, hackers must first go to a computer’s System Preferences page. If they click the lock icon, from there they’re taken to a separate login window. Typing "root" in the username field and leaving the password blank then allows the hackers to set up their own account after clicking the unlock button a few times.

You don't have to be a tech wizard to gain access to a computer this way. As long as someone knows the secret, they can infiltrate a Mac's sensitive data, whether through the lock screen, the unlocked desktop, or even remotely through screen-sharing services.

If you think your computer may be at risk, don't trigger the bug yourself just to check if it's there: According to security experts, activating it once will only make it easier for outside parties to go down the same path. The best move is to eliminate the issue as quickly as possible. Luckily, Apple released a security update that solves the issue on Wednesday, November 29. To enable it, go to the App Store, click Updates, press Command-R to see the newest updates, and select the option labeled Security Update to install it.

Don't Pour Alcohol on Your Bed Bugs—Try These Tips Instead

Getting bed bugs is a nightmare experience, one that’s sure to cost you oodles of time, money, and emotional distress. The bugs are painfully hard to purge from your household, and it’s getting even harder as they become more resistant to common insecticides. Unfortunately, home remedies are often no match for these parasitic insects. Dousing them with rubbing alcohol (a tip you'll often hear) won’t kill them; in fact, it might just burn your house down, as a woman trying to rid her Cincinnati apartment of bed bugs found out recently. As The Washington Post reported, the alcohol in that case was too close to the flame of a candle or some type of incense, and ignited. It wasn't an isolated incident.

In the last 10 years or so, people trying to kill bed bugs with alcohol have started several house fires across the U.S., including a different incident in Cincinnati just two weeks ago. So short of burning down your entire house and starting over, how do you get rid of them?

The short answer is: Give up on the idea of saving money and call an exterminator. According to 2014 research, plenty of DIY bed bug-killing remedies are woefully ineffective. Rubbing alcohol, in fact, only killed half of the insects sprayed by the Rutgers University researchers in that study. Researchers have found that other recommended home remedies, like moth balls, foggers, or ultrasonic bug repellers, are even less effective. And don’t even think about using “natural” type products that use essential oils as the main ingredient. They might smell nice, but they won’t help your bug problem.

But before you call in the big guns, there are a few effective, concrete steps you can take to reduce your infestation. As Rutgers bedbug specialists Changlu Wang and Richard Cooper wrote in their bed bug fact sheet, putting your belongings in plastic storage bins or garbage bags is a good place to start. Since the bugs don’t like to climb on smooth plastic, this can help contain the infestation. Just make sure to treat whatever you’re putting inside the bags or bins first by putting them through the hot laundry, steaming, heating, or freezing them.

You’ll need a mattress encasement, too. This will keep the bugs that have already infested your mattress from escaping, meaning they won’t be able to feast on you anymore and will die of starvation. Nor will any new bugs be able to get inside to nest. You’ll want to make sure it’s a scientifically tested brand, though, since not all mattress encasements are bite-proof or escape-proof for bed bugs. (Most experts recommend the Protect-a-Bed BugLock encasement, which costs about $81 for the queen-sized version.)

Next, pick up some bed bug traps. Set them up under the legs of your furniture and around the perimeter of rooms to help detect new infestations and reduce existing ones. According to Wang and Cooper, a one-bedroom apartment might need eight to 12 of these traps, while bigger apartments will require more.

You’ll want to expose all your belongings to extreme temperatures before you even think about touching them again. Putting them through the washer/dryer on its hottest setting will do the trick to kill both bugs and their eggs, but if you need to eradicate bugs lurking in items you can’t wash, you can freeze them in plastic bags (as long as your freezer gets down to 0°F). You can also kill them with a steam cleaner, especially if you need to purge them from your couch or other upholstered furniture.

If you’ve still got a large number of bugs lurking in your house, you can tackle them with a vacuum cleaner, sucking them out of seams, zippers, trim, and other furniture crevices. But you’ll want to use a stocking or some other method of protecting your vacuum from being infested itself. (See Figure 6 here.)

Some research has also found that desiccant dusts that dehydrate bugs to death, like diatomaceous earth and silica gel, can be effective at controlling bed bug infestations (silica gel in particular) when spread around the perimeters of rooms, on bed frames and couches, and on furniture legs.

As we mentioned before, you’ll probably want to consult a professional even if you do all of the above, because if you miss even one bug or egg, you'll be back to where you started. The cost of an exterminator pales in comparison to the cost of throwing out everything you own, moving homes, and then realizing you’ve brought the bed bugs with you anyway.

The bad news for anyone who’s already infested is that prevention really is key when it comes to bed bugs. So brush up on what the pests look like, make sure to check your hotel room for them when you travel, and if you spot them in your apartment, make sure to warn your neighbors.

Want Priority Boarding On Your Alaska Airlines Flight This Holiday Season? Wear an Ugly Christmas Sweater

Between steep fares and crowded terminals, flying during the holidays isn’t fun. But on Friday, December 15, a special Alaska Airlines promotion will ease boarding stress and transform packed planes into mile-high ugly sweater parties, in honor of National Ugly Christmas Sweater Day. As the Los Angeles Times reports, the airline will offer free early boarding to travelers willing to don their holiday worst at the airport.

The promotion is good for all Alaska Airlines flights in the airline’s 115-city network, and for flights offered by Virgin America and Horizon Air (both of which are operated by Alaska Airlines). In addition to escaping the waiting crowds, passengers who share the most festive knitted looks will be featured on Alaska Air's social media pages if they tag their photos and videos using the hashtags #UglySweaterDay and #MostWestCoast. And since no plane aisle-turned-catwalk is complete without a soundtrack, “festive holiday-themed boarding music will play all month long to help get guests into the holiday spirit,” according to a press release.

Worried you’ll be the only person on the plane wearing a sequined Rudolph cardigan? Even if other passengers don’t get the memo, airline crew will also be wearing ugly sweaters—so feel free to unleash your inner Chevy Chase from National Lampoon's Christmas Vacation.
