WhatsApp and Telegram security codes do not prevent piracy



"Nothing more than sending an innocent photo, an attacker can take control of the account," says an investigator



A computer security company revealed that it had discovered an error in the popular messaging services Telegram and WhatsApp, which would allow hacking user accounts using the encryption system that supposedly protects the confidentiality of their messages.

The US company Check Point Software Technologies says in a statement that Telegram and WhatsApp, which alerted on March 8, fixed the problem. He did not specify, however, how many accounts could have been effectively compromised, but he assures that this failure represented a danger for "hundreds of millions" of users accessing the platforms from an Internet browser (as opposed to those who do so). through mobile applications proposed by the two services).

According to Check Point researchers, "nothing more than sending an innocent photo, an attacker can take control of the account, access the history of the messages, all the shared photos (in the service), and send messages instead of the users".

The pirate, in effect, could camouflage a virus in the image, which was activated when the recipient clicked on it. WhatsApp and Telegram use an encryption that guarantees that only the sender and the recipient of the messages can see its contents. But suddenly, the two applications had no way of detecting whether that content includes viruses. To remedy the problem, the two services validate more the content sent just before it is encrypted, which allows blocking the virus, adds Check Point.

92% of Spaniards connect to the internet at least once a day Half of the world's population is connected, reaching more than 4,000 million mariners    For the first time in history, the Network of networks reaches 4,021 million people who browse it, a figure that assumes that the Internet reaches half of the world's population, according to data from the Digital report in 2018 by Hootsuite. and We are Social. An increase in users who also move to Spain, where the figure has grown by 2 million to reach 39.4 million active Internet users , which means that 85% of Spaniards already have access to the network. "With 4,000 million online users, connectivity has already become a way of life for most of us. However, while Internet companies strive to provide service to the next billion users, we will see important changes in the coming months, "says Simon Kemp, global consultant at We Are Social.    According to the Digital 2018 report, Spaniards spend 5.20 hours a ...

Autonomous boats will arrive in Europe in 2017 The waters of the canals of Amsterdam will receive the first robots ships    If the autonomous cars begin to accumulate kilometers by the highways of the United States, to the other side of the Atlantic Amsterdam prepares to receive the first boats without captain. "Imagine a fleet of autonomous boats for the transport of goods and people," Professor of the Massachusetts Institute of Technology Carlo Ratti said in a statement from this research center. The Amsterdam Institute for Advanced Metropolitan Solutions is working on a project that will culminate in 2017 with the first trips through the capital's canals with robot ships.   The scientific director of the Dutch center, Arjan van Timmeren, said that these boats "offer enormous possibilities" and could have application in environmental and health issues, such as detecting diseases in advance once progress is made in relation to underwater robots. The project wil...

Artificial intelligence takes over the drones

Artificial intelligence takes over the drones An MIT mapping system allows unmanned aircraft to dodge obstacles at low speed     Can a drone only dodge an obstacle? The answer is yes. The Laboratory of Computer Science and Artificial Intelligence (CSAIL) of the Massachusetts Institute of Technology has managed to provide artificial intelligence to a small aircraft to fly through forests and warehouses. Nanomap, the new alternative navigation system allows you to fly over and avoid obstacles, as long as the speed of the device does not exceed 30 kilometers per hour.    Excessively safe maps will not help if you want drones that can operate at higher speeds in human environments," says graduate student Pete Florence, lead author of a new related document. "An approach that is more aware of uncertainty gives us a much higher level of reliability in terms of being able to fly close and avoid obstacles ." Shocks Many existing approaches are based on complex ...
