How to protect yourself from ransomware attacks?

Ransomware or "data hijacking" is one of the most conventional cyberattacks today. We all know that the new industry is basically managed with information and therein lies the relevance of this type of asset. For this reason, being able to protect ourselves from ransomware attacks is a priority, no matter how big your company is. Read on to find out what to do!

What are ransomware attacks?

Before we dive into protection, it is necessary to understand how this vulnerability works. In that sense, Ryuk is the most conventional ransomware. Once it is installed on the computer, it encrypts the files and the nightmare begins. The attacker will ask the user to pay a ransom in cryptocurrencies, but that will not be a guarantee.

In addition, the amount that is usually requested to recover the data is not low and even then the victim could lose everything. Now, who is the most vulnerable to ransomware attacks? First of all, business environments, but then all those that are linked to it.

Emails are usually easy targets for attackers, as well as the use of public Internet networks. Without a doubt, these two are areas to take into account in prevention.

How do I protect myself from ransomware attacks?

Now that we understand what the vulnerable sites are and how they operate, let's learn how to protect ourselves:

  • Keep your operating system up to date: Any system prior to Windows 7 no longer receives updates. Without a doubt, this is a point that could bring you problems.
  • Don't neglect your antivirus
  • Beware of spam emails: In this sense, we recommend that you have a filter. Also, you allow the antivirus to check your mail.
  • Trust your intuition: If you perceive a source to be untrustworthy, don't download anything from their site.
  • Make backup copies: This point could save you in case you lose your data. However, please note that the copy must be saved in a separate environment in order to access it.
  • Install a reliable firewall.
  • Inform your work team of these precautions.

What do I do if I receive ransomware attacks?

If you took all precautions and were attacked anyway, then be aware of the following:

  1. Don't pay a ransom. Doing so will cost you money and will not guarantee data recovery. Criminals may disappear as soon as they have the money. In addition, they could have left you an infected file.
  2. Isolate the equipment to prevent the entire network from suffering the same damage. Also, be wary of any computers that were on the network at the time of the attack and review them.
  3. Clone the hard drive to keep the original device. In it you can recover the data.
  4. Discard the infected hard drive. Recover data in a clean environment to prevent the virus from spreading again.

That's not all…

So far we have analyzed the possibility that the ransomware attack occurs in a private environment. But what happens if there is third-party data involved? In that case, the attack must be reported to the relevant authorities.

Keep in mind that not only the safety of your business is at stake, but also that of your customers or suppliers. That is why you should alert the cybersecurity agency in your area within a period of no more than 72 hours. Otherwise, it will be very difficult to track down the attacker and thus mitigate the damage.

We already see that being present on the web carries its risks. In the same way that you protect your home with an alarm or video camera, you should also protect your digital environment. This is advice that not only applies to large companies, but also to small users. Ransomware attacks are the order of the day and, although they are more frequent in companies, no one is safe.

Consider staying up to date with your operating system and antivirus. Also, be wary of any suspicious activity and never pay a ransomIn the latter case, the solution could be more expensive than the problem itself.

And you, do you already take preventive actions to defend yourself against ransomware e attacks, or are you just crossing your fingers? We would love to hear your opinion on this topic!
