Top tips to secure your devices from malware

The year 2022 has brought a digitalization at a forced march for many around the world, which had already been accelerated at an unthinkable rate by the pandemic.

However, this adoption of new technologies and the digitization process also provide more opportunities for cybercriminals to steal personal data, impersonate identities or infect corporate devices with malware.

To prevent this,here are the top tips to secure your devices from malware.

1. Only use official sites and app stores to download software:

This is one of the crucial points to note. You should stick to official sites and app stores when downloading software and updates, and avoid downloading from third-party sites. Not doing the latter puts your device at risk of being infected by malicious software or malware that can allow hackers to gain control of your device and access your critical data.

2. Avoid clicking on suspicious links:

Such as those sent by unknown senders, related to purchases, for example, that you have not made, related to accounts that you do not have, or links that do not match the service referred to in the messages. Malicious links allow cybercriminals to access your information and install undetectable viruses, spyware, or ransomware on your devices.

It is not uncommon to receive emails from strange senders or unknown contacts with links or attachments. These emails usually go automatically to the spam box, but some of them can sneak into the main box. In this case, it is essential to make sure that the sender is known and, if it is not, do not open the links or files, as they can infect the device with malware. Before clicking on suspicious links, we recommend using Nuwber and checking the basic details of that sender.

3. Turn on two-factor authentication whenever possible:

This adds an extra layer of protection to your device. If a hacker manages to crack your passwords, the intruder will still not be able to access your information, since a password will not suffice, but they will need a second code sent via phone or email.

In addition, check the permissions an application requests. If any application requests to access media files, photos, and contacts that are not necessary for its work, users should treat that as a red flag, as it could be a malicious attempt to access your device and data.

4. Use a strong and unique passwords:

A large part of cybersecurity incidents come from human error. Among the most common, using simple passwords or always the same password for different services or platforms. This puts application and account data on a tray for hackers, as they only need a program to automatically decrypt the keys. It is essential to generate strong passwords for each platform or app, change them from time to time and store them in managers available for mobile phones and computers so as not to forget them.

Passwords act as the first line of security against hackers accessing your devices and personal data. Choosing a strong password keeps your devices safe from any hackers who try to access your accounts simply by guessing it.

5. Allow the software to be updated regularly:

Using outdated software will not be up to date with the latest security protection tips and this will make your devices vulnerable to cybercriminals accessing your data, which can put you at risk of further cyber issues. Staying up to date with the latest software releases ensures your devices are continually protected and any known security holes are closed.

6. Avoid using public hotspots and Wi-Fi:

When we connect to a public network, it allows cybercriminals to access the information we send and receive, including passwords and other sensitive details, over the network. It puts your device in a position of vulnerability as it opens you up to viruses, spyware, and hackers.

7. Use a VPN, whenever possible:

This is important because a VPN (Virtual Private Network) protects user data by hiding online activity. Create a private tunnel that prevents hackers from accessing your information.

8. Use reliable antivirus or security software:

This enables continuous protection against online threats or attacks by detecting and taking action against malicious software on devices. Antivirus software is an essential step to maintaining total protection of your information and having a good security strategy.

Get in the habit of regularly clearing your browsing history, cookies, and cache. This minimizes the risk of hackers hijacking cookies and accessing personal information.

9. Better in the cloud or on the server than on the hard drive:

If you are working from home, it is not recommended to save the information on the internal hard drive of your laptop. Computers can be broken, stolen, or exposed to cyber-attacks that would put this data at risk. It is better to store all the information in cloud services or on a company’s internal server.

10. Be careful with the transmission of sensitive data:

You can never be 100% safe from cyber threats. Therefore, it is advisable to be especially careful about security in critical processes such as the transmission of sensitive information. Betting on internal chats to send crucial data is always a good idea. But if these tools are not available, it is best to send this information embedded in PDF or Word files instead of in WhatsApp messages or e-mails, as they are less vulnerable to a possible incident.

11. Backups are the best ally in the worst scenario:

Creating routine backups of sensitive information on external hard drives or cloud services is not a prevention method, but it is especially useful for recovering your personal information or sensitive data in a few minutes if it is stolen in a ransomware attack.

12. The fewer plug-ins and add-ons, the better:

With continued use, mobile and desktop web browsers can become cluttered with annoying plug-ins and search bars that at best collect browsing data and at worst can be gateways to computer viruses. Fortunately, all browsers include options to manage installed add-ons and uninstall those that seem suspicious.
