Video calling apps listen when the microphone is off, according to a study
25/04/2022A group of researchers from the University of Wisconsin-Madison (United States) has determined that video conferencing applications can continue accessing audio data even if the user has disabled the microphone. To demonstrate this, they have studied the most popular video conferencing applications and have analyzed the behavior of the mute button until they has determined that all the applications that they has tested whether the microphone was open or closed, occasionally collected raw data and delivered it to the servers of their services. In their research they have worked with binary analysis tools to see how the audio was transferred from the application to the audio drivers of the computers and then to the network. They aslo have created, through machine learning models ( 'machine learning'), a classifier of daily activities that, with 82% accuracy, has determined which activities users were doing while their microphones were, theoretically, silenced. In relation to this, the authors of this work recall that beyond muting the microphone, you can turn off the microphone of a device through the settings menu, a safer option to limit access to confidential information and sensitive data. All the conclusions of this study will be known next July in the Privacy Improvement Technologies Symposium.

Detected a Trojan that emulates the WhatsApp account and fraudulently manages subscriptions to payment sites
17/10/2022Kaspersky researchers has reported that YoWhatsApp advertised on Snaptube and Vidmate, two of the most popular download platforms at the moment, is actually a Trojan capable to issuing paid subscriptions and stealing WhatsApp accounts. YoWhatsApp would act as a mod of the original messaging program, offering new functions that the official service does not allow, such as wallpapers, personalized fonts for chats and password-protected access to conversations, .... As Kaspersky researchers have explained, when a user installs YoWhatsApp on a device, it’s forced to log in to they real application account, and in this moment, Triada Trojan is activated, downloaded and executed on the terminal. Once this is done, the Trojan is capable of accessing the user's real WhatsApp account credentials, steal all the data, having already detected unauthorized subscriptions to paid subscriptions. Kaspersky recommends to install, only, Apps from official stores and reliable sources and they have insisted on the need to check always the permissions granted to each application. Installing an antivirus is another recommended measure.

How to change the IP address?
How to change the IP address? We will explain step by step how to change your IP to be able to browse safely and anonymously on the Internet. The Internet is like a great highway and to "drive" on it, we must get on the road equipped with a computer, tablet, smartphone... with a license plate. This "license plate" is what is known as IP address and for many and several reasons, but mainly for security and/or privacy reasons, we may be interested in changing it. What is my IP? In order not to put the cart before the horse the first thing we must do to know how to change the IP of the computer is to find out what the IP of our connection is and verify that the change has been made correctly at the end of the process. Finding out what your IP is is as simple as visiting Cuál es mi IP (What is my IP). By accessing the page, without the need to download or run any program, our tool will automatically display your IP address data on the screen. This address is also useful to know if you want, for example, to configure online services such as servers, FTP, games, ... and it consists of a numerical combination. This address is unique and public and is the one that identifies us on the Internet to the websites we visit and other users. Nobody can browse the net without an IP address. The IP is assigned to us by our Internet Service Provider (ISP) and as this address is exposed on the network it is known as public IP, as opposed to the private IP of our local network, which only we can know. What is my public IP and what is my private IP? How important are they to change my IP? Our computer or any other device connected to the Internet has two IP addresses, a public IP address, and a private IP address. The public IP, as we have seen, is the one that identifies us to be able to surf the Internet (imagine driving on a highway without a license plate... we would be stopped and banned from driving!) This public IP is linked to our connection and, therefore, all devices connected to the same router have the same public IP. On the other hand, the private IP is the one that individually identifies each device in our private or home network. In this local network, each computer has a private IP address that serves to differentiate it from the rest of the computers and devices connected to the router. In this way, any request for data that comes from or is sent to a device is identified by the router so that it collects or sends the corresponding data to that device. So, which IP address should I change? Private IPs are not accessible from the Internet, while public IPs are and allow us to track our location, data, and Internet activity, including the pages we have visited or the time we have spent on each of them. So, to improve our security and privacy on the Internet, we can change the public IP, or if we prefer, hide our IP. Doing so is not complicated and now we will explain how to change the IP, but first, you must make sure if your IP address is a dynamic IP or a static one, as it depends on it that you can manage to change the IP on your own or require the intervention of your Internet Service Provider (ISP). How do I check if my IP is dynamic or static before changing it? IP addresses can be static or dynamic. In both cases, these addresses are assigned by our Internet provider and the difference between them is that in the case of the static IP, IP addresses can be static or dynamic. In both cases, these addresses are assigned by our Internet provider and the difference between one address and the other is that in the case of the static IP, the address assigned is permanent for a device or router, while the dynamic IP changes every time that device or router connects to the Internet. Usually, the IP address is dynamic, but you can check it through our free tool to find out what is your IP address on our website. Remember that you do not need to download any program or run any application. Simply access cualesmiip.com and the home page will show your IP address, indicating whether it is a static or dynamic one. If it is a static IP address, you will have to contact your Internet Service Provider (ISP) and request the change or use a VPN service as we will explain below. But if it is a dynamic IP address, the change is easy and you have several alternatives for doing so. How do I change my public IP? The easiest way to change the IP address if it is a dynamic one is to turn the router off and on again. This will change the public IP and when you browse again you will do it with a different IP address than the one you had before turning it off. The tricky part of the situation is that the new address, like the previous one, will continue to be exposed on the network and if you want to change it again you will have to turn the router off and on each time. However, it may happen that despite doing so, this does not work and the IP address does not change. This happens because in certain circumstances Internet Service Providers (ISP) establish a certain period before which IP addresses cannot be changed. How to change my IP with a VPN? If you are looking for a solution that does not force you to be aware of turning your router on or off and that also offers a permanent solution that contributes to your online security and privacy, VPNs are already the most effective solution for changing your IP. VPNs are services designed to hide the IP address, whether you connect with a static IP address or a dynamic one, using that of an intermediate server, in such a way that the IP address is masked, appearing to the public as a different IP permanently. As this new Public IP belongs to the VPN server, none of our data is exposed and whoever traces the address will only reach that server, without being able to access any data about our connection, navigation, and identity on the network. VPN vs Proxy Proxy servers act in a similar way, although VPNs have the added advantage that they encrypt all data from the beginning to the end of the communication so that the impossibility of tracing data is 100% guaranteed. Proxy servers do not have this function and therefore your connection may still be susceptible to falling prey to cybercriminals. In addition, most proxy servers, unlike VPNs, must be configured manually and even, in some cases, individually in each browser. How do I know if my IP has been changed? And now that you know how to change the IP, you can test and check whether it went well by comparing your new IP address with the one you had before. If everything went well, you will see that the numbering is different and therefore your IP has been changed.

Less than half of Spaniards change their passwords when they separate from their partner
05/10/2022The email and social network accounts of one in five Spaniards (21%) have been subject to violation by a third party who has changed the passwords without the owner's knowledge or consent, attributing 37% of the victims this wrong use to their ex-partners. This data comes from the recent study carried out by Avast and Dynata on the degree of knowledge that Spaniards have of the passwords of their partners or relatives. In this study more than 2,000 Internet users have participated. Among the most striking results of this survey is that the collaborators who say they still know their ex's passwords, 56% of them has admit that they even know, also, their professional email passwords. 24% of those surveyed also claim that their location has been tracked without their consent due to knowing their password. This behavior, the authors of the study explain, can be considerated as technological abuse, which can be further aggravated by installing spyware or 'stalkwerware' on other people's devices or controlling or harassing someone through home technology.

Google launches ChromeOS Flex to give a second life to outdated computers
21/07/2022Google has just introduced ChromeOS Flex, a new version of their cloud-based operating system that will allow "rejuvenating" Windows and Mac computers that have become available. The system must be downloaded directly from the web and can be installed on the computer via USB or the company network. ChromeOS Flex is now ready to give outdated Windows and Mac computers a second life. At the moment, Google has already certified nearly 300 devices compatible with ChromeOS Flex, from leading brands on the market such as Apple, Acer, Dell or Microsoft. Although Google has advanced that not having the certification does not prevent the installation of the operating system on our old computer. Some of the services offered by this operating system are, the protection against ransomware and malware; background updates; remote management of applications and, of course, the possibility of giving a new life to an outdated computer. “By installing ChromeOS Flex on an older computer, you're not only getting a great experience, you're also contributing to an important cause. Every year 40 million tons of electronic waste is generated worldwide, which is equivalent to throwing away 800 laptops every second. Updating devices to ChromeOS Flex instead of completely replacing them is one way to reduce this waste.

Google Health will be use to study the impact of mobile phones on our mental health
01/06/2022Spaniards spend an average of 3 hours and 40 minutes a day connected to the mobile. This time multiplied from Monday to Sunday is the same as more than 25 hours a week, according to the Digital Consumer by Generation report. To analyze the impact of all this time of digital consumption on our mental health, a group of researchers from the University of Oregon (United States) has just announced that they will use the Google Health app to analyze how users use their smartphones and discuss how in the future, digitals products and devides can make people happier, without falling into dependency. In their work, they will measure factors such as sleep or physical activity, for which they will also use the data collected by Fitbit, the activity bracelets owned by Google. One of the researchers, Dr. Nicholas Allen, stressed that "some studies similar to the one that we are going to start, usually condem the technology based on their conviction that it must be bad for mental health and well-being." . For this reason, he believes that is not positive to focuses only on the potentially harmful effects of the use of the devices, and also is important to takes into account the benefits that they offer.
