How do Ransomware Attacks Work?
A hacker obtains access to your computer or network and uses ransomware to encrypt your files, rendering them unavailable. When you request the decryption key to open your files, the attacker often demands payment in bitcoin.
In addition to vital data being stolen or destroyed, ransomware attacks have the potential to cause severe financial and reputational harm to both enterprises and people.
How Do Ransomware Attacks Happen?
Ransomware attacks typically occur in a few distinct ways, such as:
- Phishing emails designed to trick users into clicking on a link or downloading an attachment that contains the ransomware
- Malicious downloads that get installed when users visit unsecured websites or download software from untrusted sources
- Exploiting vulnerabilities in software or operating systems to gain access and install the ransomware
Whatever method the thief chooses to employ to infect their victim’s PC, the rest of the ransomware assault is quite simple.
The victim’s data are encrypted as soon as the ransomware is deployed. In order to obtain the decryption key, the hacker who carried out the attack then wants money.
Critical Ransomware Attempted

- WannaCry: As previously noted, around 200,000 machines across 150 countries were impacted by the WannaCry assault in May 2017.
- Petya/NotPetya: In June 2017, businesses in the Ukraine were hit by a ransomware assault known as Petya or NotPetya, which then swiftly expanded to other nations, including the United States.

These are just a few examples, but there are many more. Additionally, there are significant efforts that people can do to safeguard themselves in addition to businesses and local governments in order to protect themselves against ransomware attacks and other security threats.
Let’s look more closely now at ways to keep your data protected.
