Everything you need to know about security on your mobile device

Whether you have a new mobile device in your hands for the first time or you already have a long time using them, security may be an issue that you are not giving the importance that corresponds.

Our Smartphone has become a huge store of personal and private data that should not be exposed to third parties because of our inexperience and that is why today we have compiled some safety guidelines that we should all follow to protect the security of stored information. on our mobile devices.

Dangers to which we expose ourselves

This is without a doubt the era of information and mobile technology. It is for that reason that security must become an important part of our daily life, being that we occupy several minutes of the day sending messages to our family and friends, often with personal and private information, which should not be used by any other person. Likewise, through our devices, we usually carry out banking operations and usually do not realize that the Wi-Fi connection we use can be the channel through which the information of our banking data is filtered, which of course is nothing recommendable.

Minimize security risks existing on mobile devices is not as complicated as it seems. The security breaches have been greatly reduced by the latest updates of the most used operating systems such as iOS and Android. The most common thing in mobile devices is the entry of malware, which are malicious programs that are inserted and executed within the device where they are installed, of course, without the user having authorized such action. The objective of this type of software can be incredibly varied, ranging from obtaining personal data stored in the cache of our device to making subscriptions to services through the use of our banking data, although to a greater or lesser extent, all the objectives of a malware are negative for users.

The worst thing is that given the way they work, we do not even notice their presence because they operate in the background and are only recognized by the antivirus that we previously installed on the device.

Many online casino companies that are currently booming, have special security protocols to prevent these cases from their own applications, always advising their users to only access their platforms with official applications and not from third parties.

In general, the recommendation is to install an antivirus that is constantly updated to detect these types of programs, install applications only from trusted sites, preferably from the application store of each operating system and even then, before installing, check the security permits that it requires, review the comments of users to be aware of anything that offers some distrust.

Great Millimetric Telescope from Mexico, from Big Bang to Black Holes

Scrutinizing the origin of the universe or proving the existence of black holes are two of the tasks to which Mexico’s largest Millimetric Telescope (GTM), the largest of its kind in the world, will devote its time in 2018, completing 20 years of work.

A giant satellite dish 50 meters in diameter sets the silhouette of the top of Sierra Negra in the state of Puebla in central Mexico, an extinct volcano of 4,600 meters high, where temperatures are usually around zero degrees Celsius.

“There is no other millimeter telescope of this diameter, most are between 10 and 15 meters, and there are some with 35 meters. Alfonso Serrano, David Hughes.

This giant observes the millimetric electromagnetic radiation from astronomical sources, including some very fragile signals, from the colder objects traveling through space.

He not only observes long distances, like a conventional telescope but analyzes the original matter to study “the whole history of the universe,” Hughes specified.

Thanks to millimeter telescopes it is possible to study the formation and evolution of the structure of the cosmos since its emergence in the Big Bang 13.7 billion years ago.

The GTM started operating in 2011 and carried out its first research in 2014.

In 2017 a team of researchers published an article in the journal Nature Astronomy on the observation of one of the first mass galaxies that formed 12.8 billion years ago.

“He was able to detect a galaxy in the very distant universe when he was one-seventh of the size he has today,” he explained, explaining that this galaxy was “darkened in optical frequencies but very bright in millimetric frequencies because of the presence of molecular gas and gunpowder “.

The importance of this discovery, Hughes added, is not only because of the youth of this astronomical object, which will allow us to understand “the chemistry of billions of years of the universe”, but also because it holds a “connection,” a similarity, to objects we can detect in the local universe.

All this was possible when the diameter of the telescope was 32 meters, and the magnification at 50 can multiply the results, including traveling back in time.

Always in a millimeter way – analyzing radiations that reach the Earth, because the galaxy in question has possibly disappeared.

Despite its worldwide leadership, this project – a partnership between Mexico and the United States, which has the close collaboration of Massachusetts Amherst University – is part of a network of telescopes that have been working since last year in an exercise that can revolutionize science: prove the existence of black holes, which was mathematically established by Albert Einstein in the famous General Theory of Relativity in 1915.

“These objects are relatively small in the scale of the universe and we need huge telescopes to measure and detect the shadow of a black hole,” Hughes explained.

Image result for Great Millimetric Telescope from Mexico, from Big Bang to Black Holes

But in the center of our galaxy, the Milky Way, there are strong indications of a black hole with a mass equivalent to six million times that of our Sun.

With the simultaneous study of nine-millimeter telescopes distributed around the world – from Antarctica to Mexico, from Spain to Hawaii – that point to the center of the galaxy and then analyze the dataset over several days, it would be possible to get unique results.

“We are in the process of analyzing the data to produce for the first time a photo, an image that can prove the existence of a black hole. It would be a shadow, a dark region, and around light and millimetric radiation,” Hughes said.

With these perspectives, 2018 can mark a before and after in astronomy, with the implementation of 100% of the telescope, a dream of the Mexican scientist Alfonso Serrano, who died in 2011.

The construction phase of the telescope, which was very complex by the orography and costs, involved 120 people.

The project cost the US $ 200 million, 70% funded by Mexico through the National Science and Technology Council.

Once the construction of this cutting-edge telescope is finished, it is now time for research and scientific instrumentalization.

Alibaba kicks off Singles Day, expecting to break records

At midnight in China time, e-commerce giant Alibaba kicked off Singles Day, the day when the biggest amount of online sales of the year occurs and when the Chinese company hopes to beat all records.

Only in the first hour, more than $ 8.5 billion were sold. In the first hour of last year, the value reached had been of $ 5.2 billion, reason why everything indicates that the numbers will be surpassed. Thousands of Chinese were eagerly waiting for the time to arrive so they could start buying everything they have been accumulating for weeks on the cart.

Single Day or 11/11 is a real sensation in China and for years has become the number one record online sales worldwide. That day’s sales are 2.5 times greater than the total of “Black Friday” or “Cyber ​​Monday” together, when the United States trade launches its offers.

The countdown began a few minutes after the end of a huge party in Shanghai, western China, where personalities like actress Nicole Kidman encouraged the Chinese to attend the grand date. The actress presented the trailer for a short film about martial arts in which the eccentric Jack Ma, founder of Alibaba and one of China’s richest men, makes his acting debut. After the screening of the film, which debuts today, the businessman appeared on stage with other actors, all dressed in traditional costumes.

Also participating in the party were Brazilian model Victoria’s Secret Lais Ribeiro, Russian tennis player Maria Sharapova, former Portuguese soccer player Luis Figo, American singer Pharrell Williams.

This year’s goal is to beat last year’s number and exceed $ 17.8 million sold in just one day through portals like Tmall and Taobao. In this edition 140 thousand brands (60 thousand international) will offer more than 15 million products, in addition to the Aliexpress promotions, the international version with which the group works in countries like Brazil.

The event, which began in 2009, with the participation of only 27 brands, last year had a participation of more than 100 thousand stores. In all, Cainiao, the delivery company belonging to the group, processed 657 million orders and reached 175,000 orders per second.

He said a few hours before the start of the event, the company’s executive vice president, Joseph Tsai, is the most important day in the world for trade and “a great event for China’s economy.”

Hacking of data by hackers also threatens Brazil and Mexico

The kidnapping of data is growing rapidly in Latin America, especially in Brazil and Mexico, countries that have reported the highest number of victims of this week’s global cyber attack in the region, experts told Efe.

“Among the countries most affected are Mexico, which ranked fourth in the world in terms of the number of victims, and Brazil, the sixth,” said Dmitry Bestuzhev, Director of Research for Latin America at Kaspersky Lab, one of the largest computer security companies in the world, while talking about the “WannaCry” attack.

The attack, which began May 12 and exploited a vulnerability in the Windows operating system, affected 200,000 computers in 150 countries using “ransomware” to encrypt the victim’s digital data. The files are held as “hostages” until a redemption is paid to unlock them.

In the case of “WannaCry,” hackers demanded payments in the Bitcoin digital currency to restore access to computers. According to Kaspersky records, as of Monday, 236 victims had made the ransom payment.

“The problem is to pay,” ransomware “grows because people pay. Unfortunately, companies or users have succumbed to this, which increases the risk because it motivates criminals,” Efe told the director of Engineering for Latin America and the Caribbean of Symantec, Sebastian Brenner.

Symantec, another global leader in cybersecurity and this week presented the report “Threats to Internet Security” in Bogotá. The document points out that the United States remains the country with the most registered cases of ransomware in the world, with 34% of the total. In addition, 64% of American victims end up paying the ransom.

The US is followed by Japan, with 9% of the total cases. Italy followed, with 7%, followed by Canada and India, with 4%, United Kingdom, Australia, Germany, all with 3%. In Latin America, Brazil leads the list (1.4%), followed by Mexico (1.2%), Argentina (0.3%), Chile (0.29%) and Colombia (0.1%).

Bestuzhev expressed concern about the growth of the phenomenon in the region and stressed that Mexico and Brazil are at the top of the spread of this threat.

“It’s definitely easier for a cyber-attacker to attack a person than a company that has more security barriers,” said Brenner.

The Kaspersky expert agrees. “Even if it sounds like an old song, the attack would not have been that large if the victims had protected their equipment,” Bestuzhev said.

“The security patch to prevent the ‘WannaCry’ mass attack was available since March when Microsoft released an update of its operating systems. It took two months, and companies and users did not install it,” he warned.

According to Kaspersky data, one in five companies worldwide suffered a “ransomware” attack. In 2016, 32% of the victims paid the ransom. Another 67% lost some of the data they had sequestered.

“The ball is now on the side of the companies. Installing the updates is free and this should be done immediately,” added the director of Kaspersky.

The two experts pointed out that Latin America may be even more vulnerable to attacks for another reason: piracy.

“I know of companies that have Windows pirates, which break Windows security and they cannot install the updates. Failure to pay for licenses is a risk,” Bestuzhev said.

The director of Kaspersky also said that it is possible to recover the files without paying the hackers. The company is working with Interpol to decrypt the lock.

“It’s a matter of time,” he said. By Diana Marcela Tinjacá.

Researchers create robot that detects emotions when interacting with people

Spanish and Portuguese researchers have developed a robot prototype capable of detecting the emotional state of the people with whom it interacts, which enriches its knowledge and improves its ability to interact with humans.

“If the robot aims to keep a group of children entertained, from the emotional state of the group it may decide to act specifically on those young people who are emotionally farther away from the group and in this way try to homogenize the emotional state of the group” , explained Vicente Julián, of the Group of Technology in Informatics and Artificial Intelligence of the Polytechnic University of Valencia, in the east of Spain.

The robot has a screen that reflects its emotional state, as well as infrared radiation sensors, a camera to identify people, a LIDAR sensor, which measures distances and other information according to reflected light, and three Raspberry Pi computers, which constitute the ‘brain’ of the prototype.

This work is part of an international project on the interaction of robots with humans, in which the team focused on the identification of emotions and their interpretation by computer systems.

“The result of emotion monitoring is used in an innovative way, which seeks to identify one or several emotional states of a group of people and how these states propagate over time.” The robot interprets emotional changes and uses them to make decisions, “said Julian.

The results of the project can be applied in several fields in which interaction between robots and humans is required, for example in the field of robotics dedicated to assistance, commercial or educational means. Together with the Spanish university, experts from the University of Minho of Portugal took part in the study.

Family invests everything in “bitcoins” to live in camping in Holland

A Dutch family sold all their properties, including the toys of their three daughters, to invest all the money in the virtual currency “bitcoin” and live a minimalist life at a campsite in Venlo, in the south-east of Holland, while watching their capital increase.

“We are betting on this idea with a double objective: the most important thing is to lead a simple life, in which our happiness does not depend on material things, in the meantime we invest our money in bitcoins and hopefully multiply,” he told Efe the father of this family, Didi Taihuttu.

The first time Didi heard about this virtual currency was in 2012 when he “had no idea” what it was or where that system would get.

“I started to search and get interested in it. Out of curiosity, I bought some bitcoins, sold them, and I did not do it thinking that it would go much further,” he said.

Bitcoin, invented by a Japanese who uses the pseudonym Satoshi Nakamoto, is an encrypted currency created from a computer code and when it was released in February 2009 it was worth only a few cents.

The value of this criptomoneda already surpasses the US $ 6,100, according to the updated data of the page of exchange of digital currencies “Bitstamp”, with headquarters in Luxembourg.

Neither Didi nor his wife, Romaine, imagined that bitcoins would be so popular over the years, so they did not attach much importance to the subject at first.

After his father fell seriously ill in 2015, Didi spent more time with his family and left out his business, his interests and even his curiosity about the digital currency and the money that had invested in this new system.

“When my father died in January 2016, we all traveled to Bali. I was on the beach, enjoying a wonderful day, when a friend called me and asked to check the application of the bitcoins, because I would have a surprise,” he recalled.

It was at this time that the Dutch realized that digital coins are “the revolution of the monetary system” because by verifying their investment after a year and a half, the money they acquired and marketed in 2013 “had gained several zeros.”

Didi spoke to Romaine and said he was “tired” of working long hours away from family and “how attachment to material matters had killed his dreams” and that the same could happen to his daughters, seven, ten and twelve.

Since then, he has considered the bitcoins “the perfect opportunity” for a change of life and has convinced his family to sell his home, his company, three cars and a motorcycle in Holland.

“We sold even the clothes we did not wear, the girls’ toys, all the luxury goods we had and we invested everything in bitcoins,” said the father of the family.

The daughters did not understand this project at first, because they left a house with five rooms to live in a bungalow of 50 square meters in a campsite in Venlo.

“They like to sleep together and are happy with our new life,” said Didi.

According to the Dutch research institute Kantar TNS, about 135,000 families in the country have currencies currently encrypted, twice as much as last year.

Many people invest a small amount: 43% of households spent no more than 100 euros and more than half got “modest profits” from their investment.

“We are aware that this is a gamble and we can lose everything. It would be a disaster because we invested everything, but we can always go back to the routine of having a salary and working,” explained Didi.

Cryptographic expert Kijn Soeteman was surprised by the decision of the family and told the public radio and television network “NOS” that “there are still many technical obstacles that can cause strong oscillations” in this digital currency.

The system, global and decentralized, allows direct transactions between users, without intermediaries, that are registered in a public database.

Didi, who reports on her daily life at, considers herself “an example to others who want to seek freedom” and shows her confidence in bitcoins as the currency of the future.

“Even if we are millionaires, we will continue to live a simple life. The Netherlands is a very expensive country, so our plan is to go to another place, like Spain, the country of our dreams, where we will survive thanks to the bitcoins trade” , Didi concluded.

The Mobile World Congress threatens to leave Barcelona in 2019

John Hoffman, the CEO of the GSMA, organizer of the Congress of Mobile, has once again expressed concern about the situation in Catalonia and warned that the event needs “security and political stability” , so it would consider changing its seat 2019 if it could not be guaranteed in the future.

Hoffman launched this message on Wednesday during the meeting of the board of the Barcelona Mobile World Capital Foundation (MWC), which met in the Catalan capital coinciding with the general strike that collapsed the road and rail network. The executive of the association that organizes the Mobile insisted that the next edition of the MWC, which will take place between February 26 and March 1, 2018, is completely guaranteed and that the preparations are going at a good pace, but that the event it needs “security and political stability” for future editions.

These same sources have pointed out that Hoffman launched “a warning”, another one, since last October the GSMA said in a brief statement that it is “monitoring the situation in Spain and Catalonia and evaluating any potential impact for the Mobile World Capital and the Mobile World Congress ». In the Board of the Mobile World Capital are, among others, the public administrations, the Fira, the GSMA and some of the main companies in the sector.

The association that groups the telephone operators has an agreement with the partners of the event in Barcelona so that the headquarters of the Mobile will stay in the Catalan capital until the year 2023.  Last year, the Mobile World Congress registered a new record of visitors , with 108,000 professionals, and it is estimated that its economic impact was around 465 million euros.

This is an event that last year generated 13,200 temporary jobs and that boosts the economy of Barcelona and its metropolitan area during the days in which it is celebrated. The organization of the GSMA is always attentive to any type of conflict that affects this event, and in recent years the strikes in the metro service have caused the discomfort of the organization of the congress.

Bitcoin exceeds $ 5 mil mark for the first time

The value of bitcoin surpassed the $ 5,000 barrier for the first time on Thursday and set its new record high, according to the Financial Times.

At 12:05 AM, the digital currency was worth US $ 5,345.38 (equivalent to R $ 16,909.04), an increase of 10.73% during the day, according to data from the Bitstamp page.

The price of bitcoin in dollars rose more than 750% last year. Some experts warn that the digital currency is immersed in a bubble that can explode at any time, while others consider that it is still possible to increase this value.

Recent weeks have shown episodes of volatility in the price of bitcoin. In mid-September, the value dropped to about $ 3,000, after China announced an investigation into local companies working with the currency.

Despite the warnings about a possible bubble, the use of bitcoin has continued to expand in many areas. In September, London real estate The Collective announced that it will allow tenants to pay rent on bitcoins, while Japan has taken various measures to regulate its use.

Bitcoin is based on a technology created by an engineer known by the pseudonym Satoshi Nakamoto, whose real identity is unknown. The system, global and decentralized, allows direct transactions between users, without intermediaries, that are registered in a public database.

Delete browsing history? And EVERYWHERE can see her!

Anonymity on the web for most people is limited to clearing the history of web pages viewed from the web browser. It turns out, however, that there is still a way for others to see your browsing history.

Image result for Delete browsing history

The entire history of your browsing, even pages you visit in incognito mode, can be recovered by third parties. Two security experts in the network Svea Eckert and Andreas Dewes managed to gather data on the network from 3 million Germans, and they used only their own knowledge.

Eckert and Dewes also managed to get into the private history of public figures such as judges and politicians. About their way of using data “Clickstream” they spoke at the Def Con industry event in Las Vegas.

“Clickstream” is a virtual trace that leaves every user on the Internet. It records all activity on the web, including every page, subpage you visit and the time it spent on it, as well as accurate information about what the user clicked on. These data should be anonymous, which would exclude the possibility of their being deciphered by an unauthorized person.

Eckert and Dewes said they managed to bypass security and get to the vast amounts of sensitive data millions of Internet users have. According to experts, this was achieved through 10 popular browser extensions. The two “hackers” identified users by means of links in the Clickstream data that were posted by specific people on Twitter or other social media.

Image result for Delete browsing history

This allowed them to accurately identify people whose data is stored in Clickstream. German politicians whose interest in pornography and other habits have revealed their interest in the subject matter. This knowledge would be ideal for later blackmailing them.

Asked about the government’s plans to collect and secure these data, Eckert and Dewes said that firstly, it is important to consider how long the data will be stored.

“If someone is strong on the subject of data protection, then they should not be allowed at all, but for security reasons, such data may be kept for some time,” she said in an interview with BBC Eckert.

Charging the mobile in seconds is possible

Use your phone whenever you want thanks to the electrode developed by a group of researchers

At present we can not live without our mobile phone. However, the short battery life of smartphones is a problem for all those who need to be connected at all times.

For years, numerous technological investigations have focused their studies on obtaining batteries more durable and efficient. A group of researchers from the University of Drexel College of Engineering in Pennsylvania (USA) has developed a new type of electrode that charges the battery in just seconds:

Do not run out of battery

The electrode developed by this group of researchers uses MXene, a highly conductive material of electricity that allows the speed of the load to increase vertiginously. Thus, our smartphone’s battery, composed of a positive charge electrode and a negative charge electrode, stores energy during charging and then releases it to power the devices.

“This paves the way for the development of ultra-powerful power storage devices that can be loaded and unloaded in seconds, but storing much more energy than conventional supercapacitors,” said study director Yury Gogotsi.
