The first ever online premium doctor listing Doctorguru.com has unveiled its first every luxury medical portal for the medical professionals in Singapore.

The luxury e-health portal is created to bring only the best top doctors and clinics in Singapore to online patients.  The user friendly website is built for the users to find their preferred specialists. It also helps patients to learn more about what the different medical terms are and how it affects their daily lives.

The moment the user lands on a specific medical keyword like Plastic Surgery Singapore, the website will immediately display a limited number of plastic surgeons.

The user, just with one glance, will have at most 10 choices of doctors to select from. Every choice will have a short and concise description of the doctor’s contact details and a button to view the profile of doctors.

The patients will also be able to book appointments directly with Singapore doctors through a response and real-time contact form.  The visitors can also recommend the doctor to their family and friends through Facebook share button.

Doctorguru.com.sg also provides useful information for medical tourism in Singapore. It also provides information of the luxury 5 star hotels nearby private hospitals and medical healthcare centres. 

Lin Lijjie, the Founder of DoctorGuru.com.sg , said, ““After analysis of current online doctor directories or portals in Singapore, the amount of doctors listed on each portal is limitless. It is overwhelming for the online patient. They have too many choices and will not know which doctors are the top of their profession.”  He adds, “Due to the overwhelming information available online, DoctorGuru.com.sg improves the quality of Singapore’s online healthcare experience and is set to widen its scope to the rest of Southeast-Asia including Malaysia and Indonesia.”

DoctorGuru.com.sg is an online luxury e-health portal founded in December 2012 in Singapore by Lin Lijie, its sole Founder. It aims to create value for the online community by building a high-end user-friendly platform for international/local patients and accomplished medical specialists in Singapore.

Peloton vulnerable to cyber attacks, McAfee research finds

​​​​​​​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 according to the latest research from McAfee. 

For those still unfamiliar with Peloton, it is a brand of electric bikes that combines high end exercise equipment with cutting-edge technology. Its products use a wi fi connection 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.

“Behind the scenes is a standard Android tablet, and this hi-tech approach to the exercise bikes has not gone unnoticed. Viral marketing mishaps aside, Peloton has garnered attention recently regarding surrounding 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 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 remote access to the bike’s tablet, including the camera, microphone and personal data. 

To the user there would be no indication the Bike+ has been tampered with, potentially putting Peloton’s 16.7 million users at risk of  being hacked.  

The flaw was found in the Android Verified Boot (AVB) process, leaving Peloton open to attackers. 

They were able to bypass the Android Verified Boot process, which normally verifies all code and data within the system before booting. Researchers were able to get the device to boot bypassing this step. 

This can lead to an 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 any access they achieved 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 even as auditing was ongoing. The vendor was sent full details,  and shortly after, Peloton confirmed the issue and subsequently released a fix for it. 

The patched image no longer allows for the “boot” command to work on a user build, mitigating this vulnerability entirely. Further conversations between McAfee and  Peloton confirmed that this vulnerability is also 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.”
