What is Ransomware-as-a-Service (RaaS)?

What is Ransomware-as-a-Service?

What is RaaS

Ransomware-as-a-Service, or RaaS, is a subscription-based model where cybercriminals rent out ransomware tools to other attackers, similar to how SaaS operates. This model allows individuals without technical expertise to launch ransomware attacks easily. 

RaaS kits, available on the dark web, often include 24/7 support, bundled offers, and user reviews. Prices for these kits range from $40 to several thousand dollars, enabling even novice hackers to execute sophisticated attacks. This accessibility has increased the prevalence and success of ransomware attacks globally.

Is Ransomware-as-a-Service Legal?

RaaS is unequivocally illegal. Participating in any activities involving ransomware attacks, such as purchasing RaaS kits from the dark web, hacking into networks, stealing, encrypting, and downloading system files, and demanding ransom payments, is strictly forbidden by law. 

These actions constitute serious cybercrimes and are punishable by severe legal consequences. Engaging in RaaS facilitates illegal activities and contributes to the growing threat of cybercrime globally, making it a major concern for law enforcement and cybersecurity agencies.

How does RaaS work?

How does RaaS work

RaaS operates much like a legitimate software service, offering subscription-based models to aspiring cyber criminals. Providers typically charge a one-time licensing fee or a monthly membership fee, often payable in bitcoin. After creating an account and paying the fee, users can select the type of ransomware they want to deploy.

Attackers then initiate their campaigns using cost-effective methods such as phishing and social engineering to distribute the malware and infiltrate target systems. Once the ransomware is executed, it encrypts the victim’s data, rendering the machine useless. The victim then receives a message with instructions on how to pay the ransom to regain access to their files.

RaaS platforms offer extensive support, including 24/7 customer care and discussion boards where users can seek advice and troubleshoot issues. Additionally, many RaaS providers supply detailed guides on how to effectively use their ransomware, enabling even those with limited technical skills to launch successful attacks. This comprehensive support system makes RaaS a potent and accessible tool for cybercriminals.

Examples of RaaS

RaaS has become a popular and effective business model for cybercriminals, with some of the most notorious ransomware strains adopting this framework. Here are some prominent examples:

1. Egregor/Maze

Maze was a pioneer in using “double extortion,” stealing data and threatening to release it if the ransom wasn’t paid. Although Maze has ceased operations, its legacy continues through similar strains like Egregor, which also follow the RaaS affiliate model. These strains capitalize on the fear of data exposure to pressure victims into paying ransoms.

2. LockBit

Launched in September 2019, LockBit has quickly established itself in the RaaS market. It targets large enterprises, rapidly encrypting their systems and making it challenging for IT teams to detect and remove the malware before significant damage is done.

3. REvil/Sodinokibi

Known for its virulence, REvil competes with other severe ransomware strains like Ryuk. REvil affiliates often exploit unpatched Citrix and Pulse Secure VPNs to infect systems, using common networking tools that enable data sharing within organizations. Its effectiveness and destructiveness have made REvil a leading name in the ransomware world.

Cybersecurity Challenges of RaaS Attacks

RaaS has significantly lowered the barrier to entry for cybercriminals and increased the volume and sophistication of attacks. Here are some of the primary cybersecurity challenges posed by RaaS.

Fuzzy Attribution of Ransomware Incidents

One of the most significant challenges in combating RaaS is the difficulty in attributing attacks to specific attackers. Under the RaaS model, the developers of the ransomware are often separate from those who carry out the attacks. This separation means that multiple groups can use the same ransomware, leading to a murky attribution landscape. Cybersecurity professionals struggle to definitively link attacks to particular groups, making it harder to profile and apprehend the criminals involved. 

Specialization of Cybercriminals

RaaS has facilitated a division of labour within the cybercriminal ecosystem, mirroring trends in the legitimate economy. This specialization allows threat actors to refine their skills and operate more efficiently. Developers can focus on creating increasingly sophisticated malware, while affiliates concentrate on devising effective attack strategies. A third group, known as “access brokers,” also infiltrates networks and sells access points to other attackers. This specialization accelerates the pace of attacks and increases their frequency. 

More Resilient Ransomware Threats

RaaS models create a resilient and adaptable threat landscape. By distributing the risk among operators and affiliates, the RaaS ecosystem becomes more strong. Capturing affiliates does not necessarily disrupt the core operators, and affiliates can quickly switch to different ransomware kits if an operator is apprehended. This flexibility makes it challenging to shut down RaaS operations entirely. Additionally, cybercriminals have shown a capacity to reorganize and rebrand to evade law enforcement. 

Protecting against RaaS

Protecting against RaaS

Preventing RaaS attacks involves an iron-fist approach that targets the root causes and common vectors of ransomware in general. Here are key steps to protect against these pervasive threats.

1. Implement Reliable Endpoint Protection

Use modern endpoint protection solutions that use advanced algorithms to detect and neutralize threats automatically. These solutions should work around the clock to provide continuous protection.

2. Perform Regular and Frequent Backups

Regularly back up your data to minimize potential losses. Ideally, backups should occur more frequently than once a week to ensure minimal data loss in the event of an attack. Daily backups can significantly reduce the impact of a ransomware incident.

3. Make Multiple Backups

Store backups on separate devices and in different locations. This redundancy ensures that even if one backup is compromised, others remain secure and accessible.

4. Test Backups Regularly

Regularly test your backups to confirm that data can be successfully retrieved and restored. This step is crucial to ensure your backups are functional and reliable in an emergency.

5. Maintain a Rigorous Patch Program

Apply patches and updates promptly to protect against known and unknown vulnerabilities. A well-maintained patching schedule reduces the risk of exploitation through unpatched software.

6. Segment Your Network

Network segmentation can limit the spread of ransomware within your environment. By isolating critical systems and data, you can prevent the malware from proliferating across your entire network.

7. Implement Advanced Anti-Phishing Protection

Invest in advanced anti-phishing solutions to detect and block phishing attempts, which are a common method for delivering ransomware. These solutions can prevent malicious emails from reaching end users.

8. Invest in User Training

Educate your employees about the dangers of ransomware and the importance of cybersecurity. Regular training sessions can help build a culture of security awareness, making users less likely to fall for phishing scams and other social engineering tactics.

9. Build a Culture of Security

Create an organizational culture that prioritizes security. Encourage employees to report suspicious activities and reinforce the importance of following security protocols.
