Antivirus Knowledge

Cybercrime translates into crimes committed through computers over the internet. They consist mainly of the illegal use of computer equipment to promote practices such as child pornography or the theft of personal information, one of the problems that most worries most users of 'the cloud'. The ultimate goal of cybercriminals is often to appropriate without prior consent access to information and data from others: they are often owned by people, companies or governments. These attacks are usually carried out over the internet.   Cybercrime is, therefore, one of the evils that lurks in the technological age. It is, therefore, avoidable if you take some precautions when browsing the Internet and keeping your device safe with good antivirus software . Those who try to steal personal documents, and even state documents, are looking for a way to create computer programs or viruses that allow them to steal the keys or passwords of users and thus get something in return: whether

We are going to explain what exactly malware is, a type of threat that has quite a few types, from computer viruses to ransomware. Sometimes it can be a bit confusing to find you so many names to talk about the different types of malware, and we end up not knowing the differences well. In this article, we are going to try to explain everything to you. We will start by explaining what exactly malware is, and we will continue with a short list summarizing the different types of malware that you can find on the network. Later, we will give you several tips to avoid it, both knowing how they tend to spread and with other extra tips. What is malware? The word malware comes from English, and it is the result of the union of the words malicious software or malicious software. Therefore, it is a type of software or application that aims to harm the device in which it has been managed to host, install or infiltrate, be it a computer, a mobile phone or any other device. There are many type

Having our team protected against threats is important. For this, there are numerous types of software aimed at defending ourselves from possible attacks. Each of them can be focused on a different one. In this article we are going to talk about a firewall, what they are and why it is important to have one installed on our computer. We are going to analyze its main characteristics, and we recommend the best open-source firewall for your local or business network. What is a firewall? The first thing we are going to talk about is what exactly a firewall is. In Spanish, its name is firewall and it basically acts as a wall between the Internet and our computer. It allows us to filter the traffic that enters our devices through the network. We can create white lists of which applications can use the network and send and receive data, for example. We must add that a firewall can be software, which is the program that we can install on our device, or hardware, which is a device that

Cybersecurity, phishing or smishing are words that may seem foreign to our daily lives, however they are closer than we imagine. When they propose to click on an email with the promise of giving us a 0KM or that we mention credit card details in a phone call, it may be that fraud is being committed behind that. Information security is part of our commitment as a Central Bank to protect users of financial services. We have the necessary tools to reduce risks: regulations that create rights and obligations, and information through financial education. Complying with good practices is everyone's responsibility. Companies and individuals must be careful and implement actions to protect or avoid compromising the security of information. We insist on guarding our data because scammers use social engineering methods to steal your password without you even noticing. Emails that appear to be legitimate, phishing, text messages, smishing, fake phone calls are the most used scam techniq

If you've seen the Netflix show yourself, based on the novel of the same title by Caroline Kepnes, you would know how dangerous a stalker could be. They know your whereabouts and can read your messages when you don't. One in ten people admit to using stalkerware to track down a partner or ex. Cyberbullying is more common than you think Hackers use paid software for stalkerware which they would download and install on their personal computer or phone while they were still together. Stalkerware is an application that can intercept calls and text messages, log into your web browsing activity, access your location, and more. According to Business Wire, one in 10 people have admitted to using stalkware to track exes or partners. Cyberbullying, or the act of using any form of technology to track a person's whereabouts and learn about their personal information, including their address and messages, can take any form, such as the use of stalkerware. But if they all h

The confinement produced months ago by the COVID-19 pandemic has triggered the online sales of many products. Those who already had the habit of buying online have increased their purchases, and consumers who had never done it have decided for the first time to do so, and will continue to do it. It is in these moments of boom in transactions when online stores become the target of cybercriminals, in which more and more varied security breaches occur, such as theft of credit card data or fraudulent access to accounts (after the theft of login and password data). The high number of e-commerce transactions that are recorded leads to an increase in scams through social networks, DDos attacks and ransomware. For this reason, many IT departments of online stores are considering increasing security measures in terms of monitoring and visibility of the network. Threats related to network security breaches are also a matter of concern for professionals, as they can be exploited to cause syst

DIGITAL TRANSFORMATION AND CYBER THREATS  We are at a key moment in the business environment, in which all organizations are experiencing a process of digital transformation. One of the main problems is the obsolescence of legacy infrastructures, sometimes unable to cope with the demand of the new digital times. However, although this transformation will help us improve our competitiveness, efficiency, customer service and offer products more adapted to new needs, the main challenge is to be able to establish priorities and ensure that we are implementing the appropriate technology: knowing which are the technologies to bet on and which ones not. This transformation can give us that competitive advantage in the market, but at the same time, it exposes us to new risks and threats, hitherto unknown, which we have to face today in companies. Digital environments, with new tools and applications, manage a huge amount of data, which is a great attraction for cyber attackers, one of th

TROJANS Have you heard of Trojans? You will certainly know the history of the Trojan horse. Like the mythical horse that the Greeks used to enter Troy without anyone noticing, these programs try to enter your computer without raising suspicions, opening a back door for a remote attacker to access the computer. What is unique about this malware is that it appears to the user as an apparently legitimate and harmless program, but when it is run it gives the attacker remote access to the infected computer. What is the mission of a Trojan? The mission of a Trojan is to create a back door that gives an unauthorized attacker access to your computer. And its objective is not very different from other types of malware: stealing confidential and personal information. The most valuable information is undoubtedly financial information and, for this reason, banks are especially concerned about Trojans that reach computers through emails with attachments. If these files are opened, the mal

Even if we have a good antivirus installed on our computer and we pay all the attention in the world to avoid falling into the clutches of viruses, there is always a certain probability of ending up infected by this type of software. There are viruses so subtle, and with such advanced techniques, that neither we are able to recognize them nor antivirus to detect them. At least until it's too late. What is usually common is that, in a short time, our PC begins to malfunction. And that's when we start to suspect that we have a virus.   There are a wide variety of different types of malware. Each of them has a purpose and acts in a specific way. The signs of the earlier viruses were very clear. For example, some opened and closed the CD reader, others made a ball appear bouncing across the screen, and others directly erased all the information on the hard drive and that's it. That was when they didn't force a sector to write and literally burned the hard drive. Ho
