A VIRUS THAT WILL MAKE YOU CRY

Ransomware: The Silent Threat

WannaCry (which can be read as "I want to cry") is the ransomware, an aggressive type of computer virus that enters victims' PCs through an email attachment and once installed, begins to encrypt information from the computer user, hiding it and encrypting it with mathematical algorithms so that its recovery is impossible. In this article I will explain why it is dangerous, how to protect yourself using an antivirus and how to fix it if we get infected.

WannaCry a ransomware virus
In this way, this worm hijacks the user's valuable information and begins to spread through emails automatically sent to other users and also through the network to other unprotected computers. A real headache for the entire company, because this aggressive bug will lose a lot of valuable information and also operating time to the organization.

What Is the WannaCry Virus?

WannaCry is a massive computer virus type 'ransomware' (which encrypts computers) that is infecting computers and internal networks of large companies in the world. The virus affects Microsoft's Windows system and has infected computers in more than 150 countries that did not have the latest updates installed.

The WannaCry virus restricts access to your system and demands a ransom in bitcoins be paid to its owners to remove the restriction. The computer attack has already gone down in history as one of the most aggressive and, at this point, affected computers have been reported in more than 100 countries. The electronic means of payment (bitcoin) has been selected as the means of payment since it allows the anonymity of the person receiving the money to be maintained.

The Part Where You Want To Cry

But the sad story does not end there, once the network is infected and the information encrypted, making it impossible to read, the virus will show a message to the user asking for a ransom for it. If the evil code was installed, it will do everything possible to obtain a payment in Bitcoin (an electronic currency practically impossible to trace) to a foreign account, which in the least unfortunate case, will not fall below US $ 1,000. And here comes the part where the ransomware lives up to its name: WannaCry.

Security: Not Just Antivirus

If your organization has not yet had to go through this bitter experience, you still have time to act. Contact your trusted consultant now to carry out a security check on your network, keep in mind that a true Information Security plan does not only consist of having an updated antivirus, but also maintaining periodic backups of valuable information, security at the level of your network and of course adequate continuous management to monitor and be able to respond to an attack.

How to Protect Yourself From the WannaCry Virus?

§  To prevent yourself from WannaCry virus it is recommended:

§  Have the original Windows license and update it.

§  In addition, you must ensure that all the software on your computer is up to date, including your browser and the toolbar add-ons you use.

§  Use antivirus software with firewall protection enabled and up-to-date.

§  Make a backup (backup) of your information to avoid losing your data.

§  Other recommendations made by Microsoft on its website are:

§  Please do not click on any suspicious links in your emails

§  Avoid visiting unsafe or unreliable sites.

§  Do not click a suspicious link on a website, Facebook page, WhatsApp and other applications.

§  If you receive an email from a known person with a link, ask them before opening the link to confirm it. It is important to note that the infected computers forward random emails to the contact list with the virus link.

§  Fraudulent emails that use names similar to popular services such as PayePal instead of PayPal or use popular service names.
