The Electronic Frontier Foundation is celebrating Google’s addition of a 2G kill switch to Android 12. The digital rights group has been campaigning against the dated, insecure 2G cellular standard since 2020, and Android is the first mobile OS to take the group’s advice and let users completely disable 2G.

In the US, carriers shut down 2G years ago, and the 3G shutdown is already underway. Phones have not really gotten the message, though, and modems still try to connect to any nearby 2G signals automatically. The problem is that 2G is very old, and it’s a lot like connecting to a WEP-secured Wi-Fi hotspot—the security is obsolete, so it’s easy to crack. If you’re in a country where legitimate uses of 2G are long dead, the standard only serves as an attack vector via fake cell phone towers, so why not just shut it off?

The EFF explains the issues:

One of the hallmarks of Boost Mobile prepaid phones in the early 2000s was their push-to-talk (PTT), or walkie-talkie, feature, which allowed you to play your voice through another Boost Mobile user’s phone speaker with the push of a button. Microsoft is now bringing a similar feature to iOS and Android devices via its Teams app. However, Microsoft isn’t using rappers and athletes to try to make PTT seem “cool,” as Boost Mobile did. Instead, the company is positioning the feature as a way to use technology to aid frontline workers.

In a blog post on Wednesday, Emma Williams, corporate VP of modern work transformation at Microsoft, announced that the walkie-talkie ability in Teams is now available “on all iOS mobile devices, such as iPhones and iPads, in addition to Android mobile devices.”

Williams also said the feature will come to some Zebra Technologies devices, such as rugged phones or scanning devices. Such products may even have a button you can press to connect instantly, just like real walkie-talkies and Boost Mobile’s old PTT phones.

Shortly after the 2017 release of PlayerUnknown’s Battlegrounds (PUBG), creator Brendan Greene publicly aired his exasperation at just how many developers were releasing shameless clones of the game’s then-unique battle royale concept and how hard it was to stop those copycats. Now, PUBG‘s Korean publisher Krafton has filed a lawsuit against one PUBG clone it says has engaged in “rampant, willful copyright infringement” of the popular game.

In the lawsuit, Krafton alleges that mobile hits Free Fire and Free Fire Max “extensively copy numerous aspects of Battlegrounds, both individually and in combination.” Those games attracted over 100 million daily users at the end of 2020, according to the lawsuit, and brought in the majority of Singaporean publisher Garena’s more than $2 billion in revenue for that year.

Krafton also makes Apple and Google party to the suit for listing the infringing game in their mobile app stores and for ignoring a recent request to take them down. In addition, Google is allegedly liable for hosting YouTube videos showing Free Fire‘s infringing gameplay on its service.

PayPal is facing a class-action lawsuit alleging that the digital payments company violated racketeering laws by freezing customer funds without offering an explanation.

When users contacted PayPal about the frozen funds, they were told they had violated the company’s “acceptable use policy” but weren’t told how that violation had occurred, the lawsuit says. What’s more, it alleges that in at least one instance, PayPal said that a user would “have to get a subpoena” to find out why.

“PayPal violates its own Agreement by failing to provide adequate notice to users whose accounts have had holds placed on them,” the lawsuit says. When PayPal does let users know it placed a hold on their funds, “it does not inform such users why such funds are being held, how they can obtain a release of the hold, and/or how they can avoid future holds being placed on their accounts.”

Space isn’t easy on humans. Some aspects are avoidable—the vacuum, of course, and the cold, as well as some of the radiation. Astronauts can also lose bone density, thanks to a lack of gravity. NASA has even created a fun acronym for the issues: RIDGE, which stands for space radiation, isolation and confinement, distance from Earth, gravity fields, and hostile and closed environments.

New research adds to the worries by describing how being in space destroys your blood. Or rather, something about space—and we don’t know what just yet—causes the human body to perform hemolysis at a higher rate than back on Earth.

This phenomenon, called space anemia, has been well-studied. It’s part of a suite of problems that astronauts face when they come back to terra firma, which is how Guy Trudel—one of the paper’s authors and a specialist in physical medicine and rehabilitation at The Ottawa Hospital—got involved. “[W]hen the astronauts return from space, they are very much like the patients we admit in rehab,” he told Ars.

Ukraine said it was the target of a “massive cyber attack” after about 70 government websites ceased functioning.

On Friday morning targets included websites of the ministerial cabinet, the foreign, education, agriculture, emergency, energy, veterans affairs, and environment ministries. Also out of service were the websites of the state treasury and the Diia electronic public services platform, where vaccination certificates and electronic passports are stored.

“Ukrainians! All your personal data has been uploaded to the public network,” read a message temporarily posted on the foreign ministry’s website. “All data on your computer is being erased and won’t be recoverable. All information about you has become public, fear and expect the worst.”
