A new screening test that is being trialled in the UK is able to identify and potentially lower people’s risk of having a heart attack or stroke.

The revolutionary piece of testing equipment screens people for high arterial stiffness, one of the main reasons people suffer from strokes and heart attacks.

It has been so successful that the screening test, which is completely pain free and can be carried out in five minutes, is now being recommended for use by leading doctors and cardiologists.

As a result, Turn Back Time, the company that holds the global commercial distribution rights of the equipment, is in the process of establishing test centres around the world.

So far, there are multiple testing facilities in operation in the UK, Canada, Africa, and Australia and the company will be shortly setting up two more in India and the USA.

Heart attacks and strokes are two of the biggest killers in the world, in both developed and developing countries.

Turn Back Time is therefore aiming to make the test accessible to those living in poorer communities across the globe.

“This is welcome news for the millions of people around the world who for years have been totally unaware that they are at high risk of heart disease and strokes,” said Andrew Stefanczyk, the managing director of Turn Back Time.

“Once a person is made aware of their arterial condition through screening tests such as ours, steps can be taken to help lessen the risk of suffering a heart attack or stroke.”

Commenting further on the heart attack and stroke risk screening test, Andrew added: “Our cutting edge therapy is based around equipment that has been trialled and developed together with one of the world’s largest medical companies.

“The equipment can not only assess arteries for signs of stiffening and narrowing, but together with our specialised computer software, it can also make an estimate of a person's biological age.

 “Nobody else can offer this specialised therapy,” he said.  

Meanwhile, cardiologist Dr Stephen Rex, who spent months assess the effectiveness of the test, said: “The new Turn Back Time arterial stiffness test is simple, inexpensive and a safe precise way of assessing vascular stiffness.”

Peloton vulnerable to cyber attacks, McAfee research finds

2 min
​​​​​​​Software security experts McAfee discovered exercise bikes by Peloton are vulnerable to cyber attacks, which the company have since resolved 

Peloton, the popular exercise bikes, were found to be vulnerable to cyber attacks in the latest research from McAfee. 

Peloton is a brand of electric bikes that combines high end exercise equipment with cutting-edge technology. Its products use wi fi to connect to a large tablet that interfaces with the components of the exercise device, and provides an easy way for physical activity enthusiasts to attend virtual workout classes over the internet several times a week.

Peloton has garnered attention recently around the privacy and security of its products. So McAfee decided to take a look for themselves and purchased a Peloton Bike+.

The problem

Researchers looked at the Android devices and uncovered a vulnerability  that could allow an attacker with either physical access to the Bike+ or access during any point in the supply chain to gain to hack into the bike’s tablet, including the camera, microphone and personal data. 

For the person using it there would be no indication the Bike+ has been tampered with, potentially putting Peloton’s 16.7 million users at risk.  

The flaw was found in the Android Verified Boot (AVB) process. McAfee researchers were able to bypass the Android Verified Boot process, which normally verifies all code and data before booting. They were then able to get the device to boot bypassing this step. 

This could potentially lead to the Android OS being compromised by an attacker who is physically present. Even worse, the attacker could boot up the Peloton with a modified credential to gain privileges, granting them access to the bike remotely. 

As the attacker never has to unlock the device to boot it up, there would be no trace of their access on the device. This type of attack could also happen at any point from construction to warehouse to delivery, by installing a backdoor into the Android tablet without the user ever knowing. 

The solution

Given the simplicity and criticality of the flaw, McAfee informed Peloton while auditing was ongoing. The vendor was sent full details,  and shortly after, Peloton confirmed the issue and released a fix for it. 

Further conversations between McAfee and  Peloton confirmed that this vulnerability had also been present on the Peloton Tread exercise equipment. 

Peloton’s Head of Global Information Security Adrian Stone, commented on the research: “This vulnerability reported by McAfee would require direct, physical access to a Peloton Bike+ or Tread. Like with any connected device in the home, if an attacker is able to gain physical access to it, additional physical controls and safeguards become increasingly important.

"To keep our members safe, we acted quickly and in coordination with McAfee. We pushed a mandatory update in early June and every device with the update installed is protected from this issue.”
