A newly discovered vulnerability in iPhones allows users to bypass Apple’s built-in limitations – known as “jailbreaking” – for the first time in four years.
The release of a functional jailbreak for iOS 13.5, the latest version of the iPhone operating system, represents a breakthrough for the small community of users who rely on jailbreaks for everything from serious security research to simply running games and software that Apple does not allow on iPhones.
It also poses a security problem for the company, since the techniques are in effect the same ones used by malicious attackers to take over targets’ devices.
As a result, the pseudonymous developers who released the jailbreak have not gone into detail about the exact nature of the vulnerability they are exploiting.Advertisement
Pwn20wnd, the iOS security researcher who discovered the flaw, admitted to Vice that Apple would fix it “sooner or later”.
“That’s just the nature of it,” they added. “It will most likely take them at least two or three weeks to release a patch. Even when they release a patch, users can downgrade to the previous iOS version for about two weeks usually, and after that the users should stay on their versions so that the jailbreak keeps working.”
Typically, iPhones contain a host of security measures that ensure that only software approved by Apple can be downloaded and installed on the devices. The move has a twin purpose: it helps ensure the devices remain difficult to hack, and it gives Apple control of the iOS economy.
But the company’s restrictive policies about what can be listed on the App Store has long led to demand from some users for ways to install software from other sources. The company does not allow apps that break the law, for instance, preventing gamers from installing “emulators” to play retro video games, and it imposes strict limits on what apps can do when running.
The first jailbreak was released in 2007, less than six months after the iPhone launched and pre-dating the App Store. Using a vulnerability in Safari, it allowed users to install their own programs.
The ability to bypass security limitations is also a powerful draw for malicious hackers, and many jailbreaks have been repurposed as malware, leading to a cat-and-mouse game between Apple’s security teams and the developers who try to get around their barriers.
In the past few years Apple has been on top, with extra hardware in newer iPhones making it extremely difficult for any code not approved by Apple to be installed.
Pwn20wnd told Vice they did not think their success represented a change to that status quo. Instead, iOS was “just a big target for attackers”, they said. “Apple is constantly adding more features to iOS that introduce new attack surfaces.”
3 tips for logistics companies to help maintain the supply chain during a crisis
Throughout the COVID-19 pandemic, even the best supply chain and logistics companies have run into snags keeping up with demand and getting supplies to customers on time. The lessons learned can provide valuable insight.
As companies and institutions of all sizes and industries still grapple with the COVID-19 pandemic, their supply chain and logistics teams need to be able to refocus their efforts to keep up with the continuing demands.
Here are three things we’ve learned from the early days of the pandemic that can help logistics companies—or any other companies—when they struggle to keep up.
Prioritize crisis-based essentials
Under normal circumstances, keeping customers happy means consumer and business products need to reach their destinations on time. But these aren’t normal circumstances. People and institutions around the world are relying on life-saving and sustaining items like food, medical supplies, and personal protective equipment (PPE). While there are no guaranteed delivery dates these days, some items simply need to be prioritized.
With the increasing volume of online shopping, large e-commerce companies such as Amazon began prioritizing essential products, including household staples and medical supplies, as it struggled to deal with a surge in demand. Other items such as toilet paper, bleach, and sanitizing wipes have been taking top priority, and non-essential items such as flat-screen televisions were put on hold. Delivery service providers, like FedEx, Purolator, UPS, and others, also got behind in shipments and worked to focus on hospitals and care center needs. Leveraging its global network and logistics expertise to help organizations with mission-critical needs, FedEx focused some of its efforts on 1,000 special shipments delivering protective equipment from Direct Relief to help health centers, clinics, and hospitals.
Focus on front-line workers and those most vulnerable
We’ve all heard about the impact of the pandemic on front-line workers such as doctors, nurses, care-aids, and also those most vulnerable, including the elderly and those with lower immunity. Some online grocers were prioritizing by delivering to those more vulnerable first, including the elderly and support workers. Some online grocers have offered free delivery to medical staff and volunteers. Recognizing how busy front-line workers have been, some grocery chains have been providing them with front-of-the-line access when shopping in person. While it may not seem fair to some, these prioritizing measures are helping to save more lives.
Keep logistics and supply chain workers safe
Keeping workers safe means logistics and supply chain companies are more likely to continue to keep pace with the escalating demands for essential and non-essential goods. One delivery worker whose wife is a nurse said that while the hospital is taking steps to protect its staff, his employer could be doing more. He said he interacts with about 75 to 100 people each day and never thought he or his coworkers would be front-line workers in a pandemic. With all of the doors, handles, railings, packages, and other things that they touch each day, PPE supplies and equipment are needed by all delivery company staff. Sanitizing wipes, gloves, masks, and other PPE are essential for front-line delivery, stocking, and other staff to ensure they can deliver PPE equipment to hospitals and care centers or food to the vulnerable.
By prioritizing crisis-based essentials, especially for front-line workers and those most vulnerable, and keeping front-line staff safe, logistics and supply chain companies stand a greater chance of success during the pandemic.
Should You Really Be Behind the Wheel After Concussion?
Even after all of their symptoms are gone, people who have had a concussion take longer to regain complex reaction times, the kind you need in most real-life driving situations on the road, according to a preliminary study released today that will be presented at the American Academy of Neurology’s Sports Concussion Virtual Conference from July 31 to August 1, 2020. The preliminary results could have implications for how quickly experts recommend drivers get back behind the wheel after a concussion.
“People who have concussions often have slower reaction times as a result, and do more poorly on tests of thinking skills after their injury than their peers without concussions,” said Julianne D. Schmidt, Ph.D., ATC, of the University of Georgia in Athens. “Our study suggests that complicated driving skills, the kind involving split-second reaction times that could mean the difference between life and death, are the ones that may take the longest to regain after you have a concussion—even when all of your symptoms have resolved.”
The study involved 28 college students with valid drivers’ licenses and an average age of 20, including 14 with concussions and 14 without. Ten of the 14 concussed students experienced concussions while playing sports. All college students were matched by age, sex, and driving experience. Participants completed both a simulated driving reaction time test and a computerized neurocognitive test within 48 hours of their concussion symptoms resolving, which occurred an average of 16 days after the injury.
The driving reaction time test consisted of two simulated driving scenarios. The first scenario involved a stoplight reaction time simulation in which the stoplight changed from green to yellow and participants had to rapidly choose to brake or accelerate. The second scenario involved a child running in front of a vehicle and participants needed to brake or swerve to avoid collision.
The computerized test consisted of four measures of reaction time including simple, complex, and Stroop reaction time, which is the lag that occurs when you are asked to select a word like “blue” that is printed in a different color.
The drivers who had concussions demonstrated slower computerized complex reaction times than those who did not have concussions by an average of 0.06 seconds. When reacting to a change in stoplight color, it took those with concussions 0.24 seconds longer to react, or the equivalent of 15.6 feet in stopping distance, compared to those without concussions. During the driving simulation involving a child running in front of a car, it took those with concussions 0.06 seconds longer to react, or the equivalent of 3.3 feet in stopping distance, compared to those without concussions. Slower reaction time is a strong predictor of crash risk, and these additional split seconds and feet needed to change the vehicle’s movement could be critical for avoiding an accident. Interestingly, only the computerized complex and Stroop reaction times moderately related to the driving stoplight reaction time, and no other relationships were observed, suggesting computerized reaction time measures are not a perfect replacement for measuring real-life driving reaction times.
“Overall, after the symptoms of the drivers with concussions resolved, their reaction times were similar to drivers who didn’t have concussions. However, when we looked specifically at stoplight reaction time, we saw lingering deficits in the drivers who had concussions,” Schmidt said. “This could mean traditional reaction time tests aren’t the best measure of driving responsiveness and readiness. And that could have important public safety implications, considering more than three million people have sports-related concussions in the United States each year.”
