In May 2017, a vicious virus known as WannaCry shook the world by infecting hundreds of thousands of computers in over 150 countries. It caused chaos and panic among individuals and businesses alike, with many still feeling its repercussions to this day. But what exactly is WannaCry ransomware? And how can you protect yourself from falling victim to it? In this blog post, we’ll dive into everything you need to know about WannaCry ransomware and share some practical tips on how to keep your computer safe from it. So let’s get started!

What is wannacry ransomware?

WannaCry ransomware is a type of malicious software that infects computers and encrypts all the files on the system, rendering them inaccessible to their owners. This malware first made headlines in May 2017 when it caused massive damage worldwide by exploiting a vulnerability in Microsoft Windows operating systems. It spread quickly from one computer to another, locking users out of their data until they paid a ransom fee.

The WannaCry virus was particularly dangerous because it could spread itself automatically through networks without any human intervention. Once infected with WannaCry, victims would be presented with an ominous message demanding payment in exchange for access to their own files.

This type of attack is called “ransomware” because cybercriminals demand a ransom from the victim before releasing control over the encrypted data. The attackers often threaten to delete or sell the stolen information if no payment is made within a certain time frame.

WannaCry was one of the most destructive types of ransomware ever seen, causing billions of dollars in damages across various industries including healthcare and finance.

How does it work?

WannaCry ransomware is a type of malware that encrypts the files on your computer and demands payment in exchange for access to them. It works by exploiting a vulnerability in Microsoft Windows, which allows it to spread quickly through networks.

Once WannaCry infects one machine on a network, it can easily move laterally and infect other machines as well. This is because the malware takes advantage of common file-sharing protocols used by many organizations.

The ransomware then encrypts all the files on an infected machine using strong encryption algorithms, making them inaccessible without paying the ransom. The attackers demand payment in Bitcoin cryptocurrency, adding another layer of anonymity to their activities.

WannaCry also has worm-like capabilities that allow it to spread across entire networks within minutes, making it incredibly difficult for IT teams to contain or eradicate once it has taken hold.

To protect yourself from WannaCry and other similar threats, it’s important to keep your software up-to-date with security patches and use reputable anti-virus software. Additionally, regular backups of your important data can help ensure you don’t lose access to critical information if you become victimized by such attacks.

How to protect your computer from wannacry ransomware

The WannaCry ransomware attack that crippled thousands of computers worldwide was a wake-up call for many. It is important to take steps to protect your computer from this type of malware.

Firstly, ensure that your operating system and software are always up-to-date with the latest security patches. Microsoft released a patch in response to the WannaCry attack, so make sure you have installed it.

Secondly, be cautious when opening email attachments or clicking on links from unknown sources. This is how WannaCry initially spread – through malicious emails and websites.

Thirdly, use antivirus and anti-malware software and keep them updated regularly. These tools can detect and remove threats like WannaCry before they can harm your computer.

Fourthly, regularly backup your data onto an external hard drive or cloud storage service. In case of a ransomware attack, you won’t lose all your valuable information if you have backups available.

Educate yourself about online safety measures by reading articles like these or attending workshops hosted by cybersecurity experts. By taking these proactive steps towards protection against cyber attacks such as WannaCry ransomware will help safeguard our digital lives today and tomorrow!

How to remove wannacry ransomware

If your computer has been infected with WannaCry ransomware, it is important to act quickly. The longer the ransomware remains on your computer, the more damage it can cause and the harder it will be to recover your files.

Firstly, disconnect your computer from any network or internet connection immediately. This will prevent WannaCry from spreading further and encrypting more of your files.

Next, download and install a reputable anti-malware software such as Malwarebytes or Norton Security. These programs are designed to detect and remove malware like WannaCry from your computer.

Run a full scan of your system using the anti-malware software. It may take some time depending on how many files you have on your computer but let it complete its scan so that all traces of malware can be removed.

If you have backups of important data, restore them after removing the WannaCry ransomware infection completely. Make sure not to use any backup created while still having an active infection since this could re-infect you again by restoring encrypted data back into unencrypted folders.

Ensure that all security updates for Windows operating systems are installed regularly so that vulnerabilities cannot be exploited by attackers in future attacks similar to Wannacry’s attack vector.


Protecting your computer from ransomware attacks like wannacry should be a top priority for all users. By following the tips outlined in this article, such as keeping your operating system updated, using strong passwords, and being cautious of suspicious emails and attachments, you can significantly reduce your risk of falling victim to this dangerous malware.

Remember that prevention is key when it comes to cybersecurity. Be proactive about protecting yourself and your devices so that you can avoid the headaches and potential financial losses associated with a ransomware attack.

If you do find yourself infected with wannacry or any other type of ransomware, seek professional help immediately. Do not attempt to remove the malware on your own unless you have extensive experience in doing so. With prompt action and expert assistance, there is hope for recovering from even the most intense ransomware attacks.
