How Far Can An EULA Go?

May 20, 2023 by 70 Comments

We read this news with mixed glee and horror: a company called Telly is giving TVs away, for the low price of having to live with an always-on advertisement bar and some pretty stringent terms and conditions. Break the terms, and they’ll repossess your TV. If you don’t give them the TV, they have your credit card on record and they think the set is worth $1,000.

The hacker in me sees free hardware, so I checked out the terms and conditions, and it doesn’t look good. They’ve explicitly ruled out opening up or physically modifying the device, and it has to continually have WiFi – for which you pay, naturally. It sounds like it could easily tell if you try to tamper with it. My next thought was, perhaps too cynically, to get one, put it in the closet, and wait for the company to go bankrupt. Because you know that business model isn’t going to last.

But it’s clear that they’ve seen through me. The most bizarre clause is that you have to “Use the Product as the primary television in Your household”. Now, we’re not lawyers, but it seems like an amazing stretch that they can tell you how intensively you are to use the product. Can you imagine a license with a keyboard that demanded that you only use it to write sci-fi novels, or that you have to use it more than any other keyboard?

Nope. Too many hoops to jump through for a silly free TV. You can keep your dystopian future.

Faster Glacier Melting Mechanism Could Cause Huge Sea Level Rises

May 19, 2023 by 115 Comments

When it comes to the issue of climate change, naysayers often contend that we have an incomplete understanding of the Earth’s systems. While humanity is yet to uncover all the secrets of the world, that doesn’t mean we can’t act on what we know. In many cases, as climate scientists delve deeper, they find yet more supporting evidence of the potential turmoil to come.

In the stark landscapes of Greenland, a team of intrepid researchers from the University of California, Irvine, and NASA’s Jet Propulsion Laboratory have unearthed a hidden facet of ice-ocean interaction. Their discovery could potentially flip our understanding of sea level rise on its head.

This Week In Security: .zip Domains, Zip Scanning

May 19, 2023 by 17 Comments

The world may not be ready, but the .zip Top Level Domain (TLD) is here. It’s a part of the generic TLD category, which was expanded to allow applications for custom TLDs. Google has led the charge, applying for 101 such new TLDs, with .zip being one of the interesting ones. Public registration for .zip domains has been open for a couple weeks, and some interesting domains have been registered, like update.zip, installer.zip, and officeupdate.zip.

The obvious question to ask is whether this new TLD can be abused for scamming and phishing purposes. And the answer is yes, sure it can. One of the trickiest ways is to use the AT symbol @ in a URL, which denotes user info at the beginning of the URL. It usually is used to include a username and password, like http://username:password@192.168.1.1/. That is pretty obvious, but what about https://google.com@bing.com? Still looks weird. The catch that really prevents this technique being abused is that slashes are disallowed in user data, so a abusive URL like https://google.com∕gmail∕inbox@bing.com is right out.

Except, take a look at that last link. Looks like it has slashes in it, so it should take you to google, and ignore the AT symbol. But it doesn’t, it goes to Bing. You may have guessed, it’s Unicode shenanigans again. Those aren’t slashes, they’re U2215, the division slash. And that means that a .zip TLD could be really sneaky, if the apparent domain is one you trust. Continue reading “This Week In Security: .zip Domains, Zip Scanning” →

Revisiting Folk Wisdom For Modern Chronic Wound Care

May 18, 2023 by 81 Comments

In the constant pursuit of innovation, it’s easy to overlook the wisdom of the past. The scientific method and modern research techniques have brought us much innovation, which can often lead us to dismiss traditional cultural beliefs.

However, sometimes, there are still valuable kernels of truth in the folklore of yesteryear. This holds true in a medical study from Finland, which focused on the traditional use of spruce resin to treat chronic wounds, breathing new life into an age-old therapy.

Two Factor Authentication Apps: Mistakes To Malware

May 17, 2023 by 58 Comments

Everyone in security will tell you need two-factor authentication (2FA), and we agree. End of article? Nope. The devil, as always with security, is in the details. Case in point: in the last few weeks, none less than Google messed up with their Google Authenticator app. The security community screamed out loud, and while it’s not over yet, it looks like Google is on the way to fixing the issue.

Since 2FA has become a part of all of our lives – or at least it should – let’s take a quick dip into how it works, the many challenges of implementing 2FA correctly, what happened with Google Authenticator, and what options you’ve got to keep yourself safe online.

Microbubbles And Ultrasound: Getting Drugs Through The Blood-Brain Barrier

May 16, 2023 by 19 Comments

The brain is a rather important organ, and as such, nature has gone to great lengths to protect it. The skull provides physical protection against knocks and bumps, but there’s a lesser-known defense mechanism at work too: the blood-brain barrier. It’s responsible for keeping all the nasty stuff – like bacteria, viruses, and weird chemicals – from messing up your head.

The blood-brain barrier effectively acts as a filter between the body’s circulatory system and the brain. However, it also frustrates efforts to deliver drugs directly to the brain for treating conditions like brain tumors. Now, scientists have developed a new technique that may allow critical life saving drugs to get through the barrier with the help of ultrasound technology.

Making The Case For All-Female Exploration Missions To Mars And Beyond

May 16, 2023 by 118 Comments

A recent study in Nature Scientific Reports by Jonathan P. R. Scott and colleagues makes the case for sending exclusively all-female crews on long-duration missions. The reasoning here is simple: women have significant less body mass, with in the US the 50th percentile for women being 59.2 kg and 81.8 kg for men. This directly translates into a low total energy expenditure (TEE), along with a lower need for everything from food to water to oxygen. On a long-duration mission, this could conceivably save a lot of resources, thus increasing the likelihood of success.

With this in mind, it does raise the question of why female astronauts aren’t more commonly seen throughout Western space history, with Sally Ride being the first US astronaut to fly in 1983. This happened decades after the first female Soviet cosmonaut, when Valentina Tereshkova made history in 1963 on Vostok 6, followed by Svetlana Savitskaya in 1982 and again in 1984, when she became the first woman to perform a spacewalk.

With women becoming an increasingly more common sight in space, it does bear looking at what blocked Western women for so long, despite efforts to change this. It all starts with the unofficial parallel female astronaut selection program of the 1950s.
