Ransomware: What to Expect in 2023 and How to Prepare?

Ransomware is a type of malware that has become a growing threat to individuals and businesses worldwide. When ransomware infects a computer system, it encrypts the files and demands payment, usually cryptocurrency, to provide the victim with the decryption key necessary to regain access to their files. The impact of ransomware attacks can be devastating, resulting in the loss of sensitive data, the disruption of critical systems, and significant financial losses.

In 2023, the ransomware threat will continue to increase, with cybercriminals becoming more sophisticated in their tactics and targets. It is essential to prepare for this threat by understanding what to expect and taking proactive steps to protect yourself and your organization. This article will discuss the current state of ransomware, what to expect in 2023, and guide on preparing and protecting yourself from this growing threat.

What is Ransomware? 

Ransomware is malicious software designed to deny access to a computer system or its data until a ransom is paid to the attacker. Typically, ransomware encrypts the victim’s files and demands payment in exchange for the decryption key required to unlock them.

There are several different types of ransomware, including:

  1. Encrypting ransomware: This type of ransomware encrypts the victim’s files, making them inaccessible until a ransom is paid. Examples of encrypting ransomware include WannaCry, Petya, and Locky.
  2. Locker ransomware: Locker ransomware locks the victim out of their computer entirely, preventing them from accessing files or applications. Examples of locker ransomware include Winlocker and Police Locker.
  3. Scareware: Scareware tricks the victim into believing their computer is infected with malware or viruses and demands payment to remove the fake threat. Examples of scareware include Antivirus 2010 and System Defender.

Ransomware is usually spread through phishing emails or malicious attachments, but it can also be delivered through malicious websites or infected software. Once the victim’s system is infected, the ransomware will begin encrypting files or locking the system, demanding payment in exchange for access to the files or the system. It is important to note that paying the ransom does not guarantee the return of the files or system access, and victims are advised not to pay the ransom.

Top 5 Targets of Ransomware

Ransomware attacks can target anyone with a computer, but some individuals and organizations are more likely to be targeted than others.

 Here are the top 5 targets of ransomware attacks:

  1. Small and medium-sized businesses (SMBs): SMBs are a common target of ransomware attacks due to their lack of cybersecurity resources and expertise.
  2. Healthcare organizations: Healthcare organizations are often targeted because they have valuable patient data that can be used for identity theft or sold on the dark web.
  3. Government agencies: Government agencies are a popular target due to their valuable data and critical systems.
  4. Educational institutions: Educational institutions are a target because they have valuable data, including student and faculty records, research data, and intellectual property.
  5. Financial institutions: Financial institutions are targeted due to their access to valuable financial data and personal information.

These targets are at a higher risk because they typically have weaker cybersecurity defenses than larger organizations, and cybercriminals see them as easy targets for extortion. Additionally, these organizations often hold valuable data and information that can be used for identity theft or sold on the dark web, making them attractive targets for cybercriminals.

Top 3 Causes of Successful Ransomware Attacks

There are several causes of successful ransomware attacks, but here are the top 3:

  1. Lack of employee cybersecurity awareness: Employees who lack cybersecurity awareness are more likely to fall for phishing scams or other social engineering attacks that can lead to ransomware infections. Examples of these types of attacks include emails that appear to be from a trusted source, such as a bank or coworker, asking the recipient to click on a link or download an attachment. To prevent this, employees should receive regular cybersecurity training that includes information on spotting and reporting phishing attempts.
  2. Unpatched software and operating systems: Unpatched software and operating systems can leave vulnerabilities in a system that ransomware attackers can exploit. Examples include the WannaCry ransomware attack that exploited a vulnerability in Microsoft Windows. To prevent this, individuals and organizations should ensure that all software and operating systems are updated with the latest patches and updates.
  3. Weak or non-existent backups: Ransomware attackers often threaten to delete or destroy files if the ransom is not paid. If the victim has weak or non-existent backups, they may feel forced to pay the ransom to avoid losing their data. Individuals and organizations should regularly back up all important files and data to an external hard drive or cloud storage service to prevent this. Backups should also be routinely tested to ensure they can be restored if needed.

By addressing these common causes of successful ransomware attacks, individuals and organizations can significantly reduce their risk of becoming victims. It is also important to have a comprehensive incident response plan in place to respond to a ransomware attack quickly and effectively.

How Do Most Ransomware Attacks Start?

Ransomware attacks can begin in various ways, but the most common distribution method is through phishing emails or other social engineering tactics. Here are some common techniques used by cybercriminals to distribute ransomware:

  1. Phishing emails: Cybercriminals will often send phishing emails that appear to be from a trusted source, such as a bank or coworker. These emails often include a link or attachment that, when clicked on, will download and install ransomware on the victim’s computer.
  2. Malvertising: Cybercriminals can also use malvertising to distribute ransomware. Malvertising involves placing malicious code in online ads that, when clicked on, will download and install ransomware on the victim’s computer.
  3. Exploiting vulnerabilities: Cybercriminals can also exploit vulnerabilities in software and operating systems to distribute ransomware. This was the case with the WannaCry ransomware attack, which exploited a vulnerability in Microsoft Windows.

Once ransomware is downloaded and installed on a victim’s computer, it will typically begin encrypting files and demanding payment in exchange for the decryption key. Individuals and organizations need to be aware of these distribution methods and take steps to prevent them, such as educating employees on how to spot phishing emails and keeping the software and operating systems up to date with the latest patches and updates.

What are Some Common Signs of Ransomware?

It can be challenging to detect ransomware because it often operates in the background, silently encrypting files and demanding payment. However, there are some common signs that a device has been infected with ransomware:

  1. Locked files: Ransomware encrypts files and makes them inaccessible to the victim. If files suddenly become locked or inaccessible, it may be a sign of a ransomware attack.
  2. Pop-up messages: Ransomware often displays pop-up messages demanding payment in exchange for the decryption key.
  3. Slow performance: Ransomware can slow down a device’s performance, as it works in the background to encrypt files.
  4. Unusual network traffic: Ransomware may communicate with a remote server to receive commands or send data, resulting in unusual network traffic.

If you suspect that your device has been infected with ransomware, it is important to disconnect it from the internet and seek professional help immediately.

Can Ransomware Spread Through WIFI?

Yes, ransomware can spread through WIFI networks. If a device on the network becomes infected with ransomware, it can spread to other devices on the same network. This mainly concerns organizations with multiple devices connected to the same WIFI network.

To protect your WIFI network from ransomware attacks, it is important to take the following steps:

  1. Use strong passwords: Use strong, unique passwords for your WIFI network and ensure they are not easily guessable.
  2. Keep software and firmware up to date: Regularly update the software and firmware on your WIFI router to ensure it is protected against the latest vulnerabilities.
