A WhatsApp vulnerability allows you to spy on group conversations


A WhatsApp vulnerability allows you to spy on group conversations



The application is renewed with new functions to avoid Telegram competition



   Despite the end-to-end encryption implemented in WhatsApp conversations, the application of the Facebook universe has an important security hole, according to a group of cryptography researchers from the Rühr University in Bochum (Germany).

These researchers have discovered a problem in WhatsApp through which it is possible to access without permission in a private group of the application through the falsification of the mechanism of verification of invitations from the servers of the app, if these are hacked.

   Researchers at Rühr University in Bochum (RUB) have discovered flaws in the encryption process of applications such as Signal, Threema or WhatsApp, which, in the case of the latter, would allow anyone who is able to access their servers to introduce a person in a private group chat without the permission of your administrator.

According to the Wired portal, this vulnerability has its origin in a 'bug' of the application, which does not use any verification mechanism for invitations to groups that its own servers can not falsify.

In this way, if an attacker controls a WhatsApp server, you can use it to easily add a new member to the group without the intervention of the user who manages it.

In addition, German researchers have verified that from the server 'hacked' it is possible to block the appearance of messages such as, for example, warnings for the presence of an unwanted person in the conversation, or forge notifications to deceive the administrator and that he thinks that the intruder has been invited by another person in the group.

A spokesperson for WhatsApp has confirmed to the aforementioned portal the existence of this vulnerability, but has ensured that the addition of a person to a group can not be done secretly, since there always appears a notification that warns of the incorporation of a new user to the collective conversation.

New changes
The application's engineers are still working to prevent their big rival Telegram from eating ground and more users, although their leadership is incontestable, at least in Spain.

The new update of the platform allows you to listen to the audio notes before sending them, to check if it has been recorded correctly. For now, the beta update is available for Apple systems, although it will arrive in the coming weeks for phones equipped with Android.

A first step in the modification of the voice notes, but there is another great step demanded by the users of WhatsApp and that is the recording of audio in hands-free mode and without pressing any button.

The dog-robot Aibo of Sony devastates in the presale This intelligent animal is capable of creating emotional connections with humans | It's an update that Sony launched in 1999 and costs 1,480 euros    The domestic robot Aibo, an intelligent dog capable of creating emotional connections with humans launched today by the technological giant Sony, sold out all its stock during the early sale. The first series of artificial pets has been delivered to their owners, after three rounds of pre-orders were exhausted last year, explained a spokesman for the company, who declined to disclose the number of units sold.    The first 30 owners of the Aibo received their dog-robot at a special ceremony at the Sony headquarters in Tokyo, in which the company wanted to celebrate its return to the world of domestic robotics after 12 years. Aibo, an update of the pioneering dog-robot that Sony launched on the market in 1999 , maintains the name of its predecessor, but incorpor...

Connectivity and sustainability, keys to the transport of the future The Movin'On congress confirms its status as a benchmark in the field of mobility in its second edition          The technological revolution is transforming the world at lightning speed. Scenarios that seemed typical of science fiction are now a reality. It happens in all areas, also in transport, subject to a deep mutation not only in the models but in what concerns its very conception. If a few years ago everything revolved around the ownership of vehicles, today other forms of business are imposed, such as car-sharing or rent for days, hours and even minutes of cars with which to meet the demands of Customers who need customized solutions. The electric car is fully established and gains support within a market that progressively moves towards decarbonization, automation and connectivity, as evidenced in the second Movin'On mobility conference , sponsored by Micheli...

Artificial intelligence is able to pre-empt medical diagnoses

Artificial intelligence is able to pre-empt medical diagnoses The Alphabet project can predict when a patient will get worse Alphabet, the parent company of Google, and the US Department of Veterans work hand-in-hand to take the technology to the patients' rooms to monitor and monitor possible changes in the health status of the elderly. However, this union is not about electronic devices to monitor the heartbeat or to control blood pressure or tension, but both companies work on the deployment of DeepMind, the artificial intelligence of Alphabet. According to several medical studies, one out of ten deaths in hospitals occurs after obviating any change in the patient's health status. The Alphabet project and the US administration will analyze patterns of 700,000 anonymous medical records to see if Artificial Intelligence from DeepMind can identify which patients will get worse during admission to the hospital and find out their future doctor DeepMind and its engineers say that ...
