Ransomware attacks have become increasingly prevalent in recent years, with cybercriminals using malicious software to encrypt victims’ files and demanding payment in exchange for the decryption key. These attacks can have devastating consequences, causing businesses and individuals to lose access to critical data and costing them significant amounts of money. In this article, we will explore the rise of ransomware attacks, the tactics used by cybercriminals, and most importantly, how you can protect your data against these threats.
Understanding Ransomware: What It Is and How It Works
The encryption of a victim’s files, followed by a demand for payment in exchange for the decryption key. This can be an incredibly stressful and frustrating experience for anyone who falls prey to it.

The Rising Threat Of Ransomware Attacks: Statistics And Trends
Ransomware attacks are becoming an increasingly prevalent threat to individuals and businesses alike. Here are some statistics and trends highlighting the rising threat of ransomware attacks:
- In 2020, the average ransomware payment increased by 178% to $312,493, compared to $112,000 in 2019.
- The total cost of ransomware attacks is estimated to reach $20 billion by 2021.
- The healthcare industry has been particularly hard hit by ransomware attacks, with the number of attacks increasing by 350% in 2020.
- In addition to healthcare, other industries that are frequently targeted by ransomware attacks include finance, manufacturing, and education.
- Ransomware attacks are becoming more sophisticated, with attackers using tactics such as double extortion, where they threaten to release sensitive data if the ransom is not paid.
- The use of ransomware-as-a-service (RaaS) is also on the rise, making it easier for cybercriminals with little technical expertise to launch attacks.
- The COVID-19 pandemic has led to an increase in the number of ransomware attacks, with attackers taking advantage of the disruption caused by remote working and the increased use of online services.
These statistics and trends highlight the serious threat posed by ransomware attacks and the need for individuals and organizations to take proactive steps to protect against these threats.
Tactics Used By Cybercriminals In Ransomware Attacks
Ransomware attacks are carried out by cybercriminals using a variety of tactics to gain access to a victim’s computer or network and encrypt their files. Here are some common tactics used by cybercriminals in ransomware attacks:
- Phishing emails: Cybercriminals often use phishing emails to distribute ransomware. These emails appear to come from a legitimate source and typically include a malicious attachment or link. When the victim opens the attachment or clicks on the link, the ransomware is downloaded onto their computer.
- Exploiting vulnerabilities: Cybercriminals may exploit vulnerabilities in software or operating systems to gain access to a victim’s computer or network. Once they have gained access, they can install and run the ransomware.
- Remote Desktop Protocol (RDP) attacks: Cybercriminals may use RDP attacks to gain access to a victim’s computer or network. RDP allows users to connect to another computer over a network and is often used by businesses to enable remote working. Cybercriminals can exploit weak passwords or other vulnerabilities in RDP to gain access and install ransomware.
- Malvertising: Cybercriminals may use malvertising to distribute ransomware. Malvertising involves placing malicious code in online advertisements, which, when clicked on, can download and install ransomware onto the victim’s computer.
- Watering hole attacks: Cybercriminals may use watering hole attacks to target specific groups of users. This involves compromising a website that is frequently visited by the target group and using it to distribute ransomware.
- These tactics highlight the importance of taking proactive steps to protect against ransomware attacks, such as keeping software and operating systems up-to-date, using strong passwords, and regularly backing up important files.
What To Do If You Fall Victim To A Ransomware Attack: Steps To Take
If you have fallen victim to a ransomware attack, it can be a stressful and frustrating experience. However, there are steps you can take to mitigate the damage and potentially recover your files. Here are some steps to take if you fall victim to a ransomware attack:
- Disconnect from the internet: As soon as you become aware that your computer has been infected with ransomware, disconnect it from the internet to prevent the malware from spreading to other devices on your network.
- Identify the type of ransomware: If possible, try to identify the type of ransomware that has infected your computer. This can help you to determine whether there is a known decryption tool that may be able to recover your files.

- Do not pay the ransom: Although it may be tempting to pay the ransom to get your files back, there is no guarantee that the cybercriminals will actually decrypt your files once they receive payment. Additionally, paying the ransom only encourages further ransomware attacks.
- Report the attack: Report the attack to law enforcement agencies, such as the police or the FBI. This can help to track down cybercriminals and prevent further attacks.
- Restore your files: If you have backups of your files, you can restore them from your backup. Be sure to thoroughly scan your backup for any malware before restoring your files.

If you do not have backups, you may need to seek the help of a professional data recovery service.
- Reinstall your operating system: To ensure that all traces of the ransomware have been removed from your computer, you may need to reinstall your operating system.
- Learn from the experience: Take the opportunity to learn from the experience and put in place measures to prevent future attacks. This may include regular backups, anti-malware software, and user training to prevent phishing attacks.
