Vulnerability in Bluetooth makes it possible to follow iPhones, Macs and more

A university has discovered a vulnerability in Bluetooth security that allows devices to be tracked. iOS, macOS, and watchOS are affected, as are Windows laptops and tablets. What can you do about this?

The vulnerability has been discovered after a Boston University study, writes ZDNet. To connect to a Bluetooth device, the signal sends typically out a continually changing address. This prevents you from being followed for a more extended period. The random chance of that address can be intercepted by a unique algorithm.

Bluetooth vulnerability in iOS, macOS and more

This vulnerability affects iPhones, iPads, Apple Watches, Macs, and Windows 10 devices. According to the researchers, Android devices are not affected because they connect differently. The unique algorithm, which the researchers call the address-carryover algorithm, does not break into Bluetooth security. In this way, a device can be permanently monitored unnoticed. There is no access to personal information, but there is an insight into your activities.

As a user, you don't notice the vulnerability. It is not known whether this problem has already been exploited. Both Apple and Microsoft were informed on November 2018 but did not respond to the content. You can read more details about the vulnerability of the Bluetooth connection in the extensive report from the university. In it, they also write that fortunately there is a temporary solution to prevent hackers from following you.

A temporary solution
According to the researchers, it helps to temporarily switch Bluetooth off and on on your iPhone, iPad, and Mac. At that time, the address is randomly composed again, so that tracking is not possible. Please note that this only works via the settings and not via the Control Panel. We expect that both Apple and Microsoft will soon come up with a software update that solves this problem. If such an update is available, you will, of course, read it on culture.

If you already suffer from Bluetooth problems on your iPhone and you are unable to connect, you can read our solutions for this problem in our tip.

"Samsung gives Note 10 faster charger, Plus supports 45 Watt."

The Galaxy Note 10 is probably supplied with the fastest Samsung charger so far, of 25 Watt. The Plus version of the flagship supports even more powerful chargers in theory, but you have to purchase it yourself.

"Samsung Galaxy Note 10 charger gets faster."
Samsung is introducing multiple variants of the Galaxy Note 10 on August 7, all of which come with a 25-watt charger. Claims the usually reliable telecom insurer Ice Universe on Twitter. It would be a significant upgrade compared to the Galaxy S10, which supports a maximum of 15 watts.

Various Samsung rivals are now putting faster chargers on their smartphones. For example, with the OnePlus 7 Pro, you get a 30 Watt charger, and Hweigh has been opting for 40 Watt chargers with devices like the P30 Pro for a while now. Although Samsung does not yet have top tools with chargers faster than 15 Watt, it recently released the affordable Galaxy A70 with a 25 Watt adapter.

45 Watt for Note 10 Plus
Although both the Galaxy Note and the Note 10 Plus are supplied with the same charger, the more expensive Plus model can charge a little faster on paper. According to the source, this variant supports a maximum of 45 watts, although you have to purchase such a smoother battery block yourself.

The higher the number of watts, the faster a battery is charged. For example, the Galaxy S10 Plus with 15-watt charger is 41 percent full after half an hour. The Huawei P30 Pro, which has a slightly larger battery but also a smoother 40-watt charger, is 70 percent complete after half an hour.

Microsoft praises security Mozilla's programming language Rust.

The programming language Rust developed by Mozilla contains all sorts of features that can ensure safer software, Microsoft has said. Research by Microsoft shows that most leaks in the proprietary software were caused by "memory corruption bugs" in the C and C ++ code.

"Now that Microsoft is expanding the code base and using more open-source software in its code, this problem is only getting bigger. And Microsoft is not the only one dealing with memory corruption bugs," said Gavin Thomas of the Microsoft Security Response Center. Thomas notes that Microsoft developers have all kinds of tools and processes at their disposal to find vulnerabilities.

It is more efficient if programmers spend less time learning tools and processes to create code without vulnerabilities. A programming language that makes it impossible to introduce memory problems in the system would help both programmers and security engineers. Thomas would like to see a programming language that combines the memory security guarantees of a word such as .NET and C sharp with the efficiency of C ++. According to Thomas, a programming language that meets this requirement is Rust, developed by Mozilla Research, which offers memory protection.

"We can learn from the way the automotive industry develops its technology to protect drivers and road users. The software security industry has the privilege to protect the programmer in the same way. Maybe it's time to delete unsafe legacy programming languages ​​and to switch to more modern, safer programming languages? ", Thomas asks the question. Microsoft is coming soon with several blogs in which it explores these programming languages ​​and will be the first to look at Rust.

Custom Radeon RX 5700 video cards from ASRock and MSI

Earlier this month we published our review of the AMD Radeon RX 5700 and RX 5700 XT "Navi" video cards. The reference maps have a more relaxed with a wind tunnel principle. Those who are not satisfied with this 'standard' version can opt for a variant with a custom cooler. ASRock and MSI have already shown their options.

ASRock has developed a "Challenger" variant of both the RX 5700 and 5700XT. The models have a more cooling with two 100 mm fans and a heat sink with copper 8 mm heat pipes. The XT also has an aluminum backplate. The clock frequencies of the Challenger RX 5700 and 5700XT are 1675 and 1650 megahertz, respectively, and are clocked, successively, 50 and 45 megahertz higher. The maximum boost clock has remained unchanged in both models.

MSI has also released more details about its custom video cards. Four versions come from both the RX 5700 and 5700XT. In addition to a Gaming X, Evoke, and Mech model, an Air Boost variant is also coming onto the market. More specifications are not yet known at the time of writing. We do know that the MSI cards will only become available mid-August.

Startup Elon Musk wants to read thoughts with wires in the brain.

Neural ink, a company founded by Tesla boss Elon Musk, wants to test mind-reading technology on test subjects next year. For this, electrodes in the form of thin wires would be implanted in the brain.

The brain implants of the American company Neural ink must make a connection between the human brain and computers possible. It would allow users to control computers with their thoughts. Neural ink announced this during a presentation on Wednesday morning. Tesla boss Elon Musk is one of the major donors of Neural ink, which was founded in 2016.

Thin wires read thoughts; it is necessary to place electrodes in the form of fragile cables in the brain. Neural ink has already implanted such electrodes in rats to measure their brain activity.

For the experiments, the company works together with scientists from American Stanford University. "We hope to have this in a person at the end of next year," said Musk during the presentation. The US regulator FTC has not yet approved the testing of technology on humans.

Operation with robot
The threads that Neural ink uses are a quarter times thicker than a human hair. For test subjects, four holes are first drilled into the skull. A robot must then place the electrodes very precisely in the brain. In the future, Neural ink hopes to use lasers to make holes in the head.

According to Neural ink, the flexible electrodes are less dangerous than the current brain implants. In the future, surgery should be as easy as laser eye surgery, says Matthew MacDonald, Neural ink chief surgeon.

"Upgrade your brain."

According to Neural ink, this technology makes it possible to write texts, such as e-mails and text messages, by thinking. It would also be possible in the future to download a new language that the person does not yet speak.

Neural ink first focuses on people who cannot move their bodies. Founder Elon Musk hopes that eventually, everyone could use the device. The first goal is to be able to write 40 words per minute by thinking.

Neural ink is not the only company that works on technology to connect brains to machines. Facebook is also working on technologies that make it possible to send thoughts to a computer. "One day we will be able to send complete thoughts to each other immediately," said Facebook boss Mark.

These 7 "stalker apps" have now been removed from the Play Store by Google.

Security researchers have discovered several apps in the Play Store that can track your location and message history. They have since been removed from the Play Store by Google.

Removed Android stalker apps from Play Store

As soon as you were able to install one of the apps on another person's Android smartphone, you could continuously view the location, contacts, text, and call history of that person. It concerned apps with names such as "Spy Tracker" and "Employee Work Spy." In the description, the developers suggested that you could, for example, keep an eye on your children, employees, or partner.

Of course, there are more apps that you can follow the location of others carefully. WhatsApp and Google Maps, among others, have been offering this option for quite some time. The big difference is that with those apps, you must explicitly give permission yourself before your location is shared with others. Also, by default, you only share your site in these apps for a short period, so that others know, for example, whether you are almost at the final destination.

These seven apps, however, continuously monitored the location of the affected users and also did so in the dark. After installation, tips appeared on the screen for how the app could be "hidden." For example, users could quickly install the app on a phone that was left behind, remove all traces of the installation and app, and then keep an eye on others in secret.

According to Avast security researchers, the apps were downloaded more than 130,000 times via the Play Store. It is unknown how often Dutch users downloaded the apps. Google has now removed the stalker apps from the Play Store and says it will check more strongly for similar apps in the future.

Samsung has already started mass-producing 12Gbit chips from lpddr5 and will be doing the 12GB modules later this month, the company announced. With a throughput of 5.5 Gbit / s, the lpddr5 chips are 1.3 times as fast as the current lpddr4x working memory with its 4.2 Gbit / s.

As part of a 12GB module, the lpddr5 can handle 44GB per second via a 64-bit full bus, where 12GB-lpddr4x gets stuck at 34.1GB / s. Moreover, according to Samsung, lpddr5 is thirty percent more efficient thanks to the use of new techniques for clocking and low-power modes. The production of 16Gbit chips of lpddr5 should start next year.

Samsung does not disclose which smartphones will get the memory first, but according to rumors, there will be a variant of the upcoming Galaxy Note 10 with 12GB-lpddr5. According to SamMobile, this is the version of Note 10 with 1TB storage. Samsung would also release variants with 256GB and 512GB storage.
