Types of Ransomware

Over the past several years, ransomware attacks have become so popular (and unfortunately, successful) that different types of ransomware have popped up. The increasing complexity of the criminal ransomware market has made it difficult for security teams to prepare against ransomware attacks, and has made it simpler for anyone who wants to launch an attack to do so.

How Flare Helps Protect your Organization Against Different Types of Ransomware

First, what is ransomware? 

We know you’re on a cybersecurity blog, but here’s a brief definition just in case:

Ransomware is malware that locks down an organization’s information, systems, data or networks, and holds them for ransom. Ransomware does this by blocking access to data, either by encrypting the data or by locking a system so the owners can’t get access.The attackers then demand a ransom for the encryption key and threaten to publish proprietary information on the public internet if the ransom isn’t paid.

How does Flare address ransomware readiness? 

Ransomware gangs gain access to your environments by taking advantage of previous data leaks, and using information from those leaks to target people in your organization, or stolen credentials to gain entry into your networks and systems. To do this, they browse sensitive information in stealer logs sold on Genesis Market, Russian Market, and both public and private groups. Flare combats this practice by continuously monitoring stolen information across the clear & dark web as well as in prominent threat actor communities. This includes monitoring for stealer logs, especially those that contain access to RDP, VPN, and SSO credentials that might lead to a compromise of your data. Once your data is found, a notification is sent to your team so they can prepare before an attack happens. 

What are the key benefits of ransomware monitoring and readiness with Flare?

• Automated continuous monitoring: Using an automated solution gives you 24/7 coverage, keeping you on top of your enterprise’s data security. 

Ransomware Types: An Overview

Are there many types of ransomware? 

Ransomware comes from humble criminal beginnings, starting as small-time scams that locked users out of their devices until a ransom was paid, often in gift cards. However, the ransomware family tree has grown considerably more complex over the years, evolving into sophisticated attacks targeting nations and large enterprises. This was likely due to the success of early ransomware campaigns and was further encouraged by the dawn of Ransomware as a Service (RaaS), which allows threat actors without technical knowledge to launch their own attacks. 

What were the original types of ransomware? 

Originally, ransomware took one of two forms: crypto and locker:

• Crypto ransomware encrypts the files on a user’s computer or device. The threat actor demands payment of a ransom in exchange for the encryption key. Wannacry is a classic example of this kind of ransomware.
• Locker ransomware locks the users out of their files, restricting access to a device or part of a system until a ransom is paid. Petya and NotPetya are examples of locker ransomware.

What are other common types of ransomware? 

Ransomware has evolved significantly over the years. Now there are several types of ransomware and ransomware attacks: 

• Scareware: Scareware displays false warnings and alerts, claiming that a computer is infected and driving users to “fix” the issue by paying for fake services or antivirus programs.
• Double (and triple) extortion: Double extortion does two things: encrypts files and steals the victim’s data, which the attacker threatens to leak if a ransom is not paid. Triple extortion goes further, threatening to act on the stolen data in some way (such as threatening customers) to extract another ransom.
• Doxware: Doxware, or Leakware, threatens to leak personal information unless a ransom is paid.
• Ransomware as a service (RaaS): RaaS is a cybercrime business model in which ransomware developers sell their malware to other criminals, allowing people with no coding experience to launch attacks.

Why is it so Important to Know About Different Types of Ransomware Now?

Why do you need a ransomware readiness solution in today’s cybersecurity ecosystem? 

Ransomware is so common that organizations are likely to experience an attack with at least one ransomware component. About one third of all attacks in 2023 involved ransomware or some other form of extortion, according to research from Verizon. Ransomware readiness empowers an organization to protect its data and minimize the potential impact of an attack. 

Why worry about more than one type of ransomware?

Ransomware poses a significant threat to businesses, as well as to their customers and partners. Because the stakes are so high, it’s critical for security teams to stay on top of ransomware trends, including prominent actors, gangs, and types of ransomware. 

What is the impact of a ransomware attack?

When an organization experiences a ransomware attack, it’s exposed to several consequences, both financial and reputational. Some of the financial costs include: 

• Disruption of operations
• Regulatory fines
• Litigation costs
• Expenses associated with remediation efforts
• The ransom fee, or fees, if the organization chooses to pay
