Is Providing Ransomware a Service Now?
What Is Ransomware As A Service (RaaS)?
The term "ransomware as a service" (RaaS) refers to a subscription-based business model that allows affiliates to carry out ransomware attacks using pre-made ransomware tools. A portion of each successful ransom payment goes to the affiliate. Ransomware as a Service (RaaS) is an adoption of the Software as a Service (SaaS) business model.
How Does The RaaS Model Work?
It would help if you started with skillfully programmed ransomware created by knowledgeable ransomware operators for the RaaS model to function. For affiliates to join and disseminate ransomware, the creators must be well-known. Software produced by reputable RaaS developers has a high possibility of penetration success and a low danger of being discovered.
Once the ransomware has been created, it is tweaked to work with many end users. The programme is then prepared for multiple affiliate licencing. Similar to SaaS products, the revenue model for RaaS solutions allows affiliates to sign up with either a one-time cost or a monthly subscription.
Some RaaS systems allow affiliates to sign up on a commission basis and do not have monetary entrance restrictions.
How Do RaaS Attacks Work?
Phishing scams are the primary method of access for ransomware victims. Phishing is a technique for acquiring private information from a trustworthy source, such as passwords and credit card numbers. The most prevalent type of phishing attempts is phishing emails. When victims open a link in an email that appears to be authentic, they unwittingly activate a cyber danger.
Affiliates of RaaS send victims phishing emails that are incredibly convincing. Victims are taken to the exploit site where the ransomware is covertly downloaded when a link is clicked. When downloaded, ransomware disables firewalls and all antivirus software before spreading throughout the compromised machine. The ransomware may cause the autonomous download of further remote access components once these protections have been breached.
A PC, laptop, or even an IoT device found to be insecure might act as a backdoor to the whole internal network of the company. A ransomware attack that penetrates further than this may hold a whole company hostage. The victim's files are now so heavily encrypted that they cannot be accessed, allowing the ransomware to continue without being noticed. The majority of ransomware runs behind permitted systems, keeping victims ignorant of any data breaches.
Following the incident, the extortion game starts.
What makes RaaS so dangerous?
Criminals considering RaaS choices have a variety of subscription models to select from, which makes this service so risky. RaaS offerings on the dark web resemble software service marketing offers from the past quite closely.
These services are offered in a variety of forms, such as:

Ransomware is extremely programmable, and purchasers are frequently given beautiful interfaces to personalise their Software. While many RaaS providers are picky about the affiliates they partner with, others enable even a novice criminal access to their toolbox.
Developers create malware, but their profits often depend on the ability of affiliates to distribute it. This is perhaps why some creators implement rigorous selection processes to ensure they only work with partners that will bring them good returns.
Example of RaaS
On the dark web, there are wide distinct varieties of RaaS. New and improved software is continually being created by operators. The following are instances of notorious ransomware that propagated through the RaaS model:
Egregor: Egregor is said to operate on an affiliate scheme, with affiliates receiving the remaining 20–30% of the ransom and developers earning the remaining 20%–30%. Egregor, which was introduced in September 2020, is said to have been a replacement for Maze RaaS, a company that shut down around the same time. A number of French companies, including Ouest France, Ubisoft, and Gefco, have fallen prey to Egregor in the last year. In France, there have been a number of recent arrests related to the extortion of Egregor.
REvil: Developers of REvil RaaS are allegedly quite picky about whose affiliates they accept. Before being admitted into the programme, applicants must demonstrate their prior hacking experience. According to reports, REvil made its creators $100 million in one year. It indicates that the legal, insurance and agricultural industries are the main targets of this ransomware.
How can you protect yourself from RaaS?
You may take certain precautions to safeguard your organisation from RaaS attacks, just as you would in the event of conventional Ransomware assaults. When it comes to cybersecurity, prevention is always preferable to treatment.
Here are some suggested defence tactics:
