Ransomware as a Service (RaaS) has emerged as a highly profitable and alarming trend in the world of cybercrime. This business model enables even the least technically inclined individuals to launch ransomware attacks and extort money from unsuspecting victims. In this comprehensive guide, we will delve deep into the workings of RaaS, its revenue models, examples of notorious RaaS operators, and most importantly, how organizations can protect themselves from falling prey to this insidious threat.
Understanding Ransomware as a Service (RaaS)
Ransomware as a Service, abbreviated as RaaS, is a subscription-based model that allows users, also known as affiliates, to access and utilize pre-built ransomware tools to execute attacks. It operates on a similar principle to Software as a Service (SaaS), where users pay a fee to gain access to software applications. In the case of RaaS, individuals with little to no programming expertise can become affiliates and launch ransomware attacks with ease.
The rise of RaaS has significantly lowered the barrier to entry for cybercriminals, enabling them to capitalize on the growing demand for ransomware attacks. Affiliates can choose from a range of ransomware variants available through RaaS platforms, paying a subscription fee or a one-time license fee to gain access to the tools and instructions necessary for executing an attack. This user-friendly approach has made RaaS an attractive option for individuals seeking quick financial gains without the need for technical expertise.
The Mechanics of Ransomware-as-a-Service
RaaS operates through a partnership between developers and affiliates. Developers create the ransomware code and provide it to affiliates, along with instructions on how to launch the attack. Affiliates, in turn, pay a fee to the developers and gain access to the ransomware tools. They then employ various techniques, such as phishing emails and social engineering, to spread the malware and infect target systems.
Once the ransomware is successfully executed, the victim’s files are encrypted, rendering them inaccessible. The attacker then displays a ransom message on the victim’s screen, demanding payment in exchange for the decryption key. The payment is typically requested in cryptocurrencies like Bitcoin, which offers a certain level of anonymity for the criminals involved.
To facilitate the smooth operation of RaaS, developers often provide 24/7 customer support to assist affiliates with any technical issues they may encounter during the attack. Additionally, RaaS platforms may offer discussion boards where affiliates can seek advice and guidance from experienced ransomware designers and providers. This level of support further enhances the accessibility of RaaS for individuals with limited technical knowledge.
The Four Revenue Models of Ransomware as a Service
RaaS platforms typically operate under one of four revenue models. These models determine how the profits from successful ransom payments are divided between the developers and affiliates. Let’s take a closer look at each revenue model:
1. Monthly Subscription Model
In this model, affiliates pay a flat fee on a monthly basis to gain access to the RaaS platform and its ransomware tools. Affiliates also earn a small percentage of each successful ransom payment collected during their attacks. This model allows for a steady stream of income for both the developers and the affiliates.
2. Affiliate Programs
Under the affiliate program model, a percentage of the profits from successful ransom payments goes to the RaaS operator. This revenue-sharing approach incentivizes affiliates to run efficient and successful attacks, as it directly impacts their earnings. The RaaS operator benefits from the increased profitability of the service.
3. One-Time License Fee
Affiliates can also choose to pay a one-time license fee, granting them access to the RaaS tools without sharing any profits with the developers. This model offers a sense of independence and ownership for affiliates, as they can continue to use the tools indefinitely without any ongoing financial obligations.
4. Pure Profit Sharing
In the pure profit sharing model, both affiliates and developers receive a share of the ransom payments collected during an attack. The specific percentages are agreed upon at the time of the license purchase. This model aligns the interests of both parties, as they have a vested interest in maximizing the profitability of the RaaS operation.
Notorious Ransomware-as-a-Service Operators
Several notable RaaS operators have gained notoriety in the cybercriminal underworld. Understanding their tactics and the impact they have had can shed light on the severity of the RaaS threat. Let’s explore some of the most infamous examples:
Hive
Hive gained widespread attention in April 2022 when it targeted numerous Microsoft Exchange Server customers using a pass-the-hash technique. Financial firms, non-profits, and healthcare organizations were among the victims. The U.S. Department of Justice disrupted Hive operations in January 2023 by seizing two back-end servers in Los Angeles. Hive left behind a trail of over 1,500 victims and extorted millions of dollars in ransom payments.
DarkSide
DarkSide is a RaaS operation associated with the eCrime group known as CARBON SPIDER. Initially focusing on Windows machines, DarkSide expanded its reach to Linux systems, targeting enterprises running unpatched VMware ESXi hypervisors or stealing vCenter credentials. DarkSide gained significant attention when it was linked to the ransomware attack on the Colonial Pipeline. The attack resulted in the theft of approximately 100GB of data and a ransom payment of nearly $5 million USD.
REvil (Sodinokibi)
REvil, also known as Sodinokibi, is the ransomware behind one of the largest ransom demands on record, amounting to $10 million. REvil is sold by the criminal group PINCHY SPIDER, which operates under the affiliate model and takes a significant portion of the profits. REvil gained notoriety for its data leak tactics, warning victims of planned leaks and providing countdown timers before making the stolen data public.
Dharma
Dharma ransomware attacks have been attributed to a financially motivated Iranian threat group. Dharma has been available on the dark web since 2016 and is primarily associated with remote desktop protocol (RDP) attacks. Attackers typically demand 1-5 bitcoins from victims across various industries. Dharma variants originate from multiple sources, making it difficult to trace the specific actors behind each attack.
LockBit
LockBit is a RaaS platform that has been in development since at least September 2019. It is primarily advertised to Russian-speaking users, with English speakers requiring a Russian-speaking guarantor. LockBit gained attention when an affiliate threatened to leak data on a Russian-language criminal forum, further highlighting the disruptive and damaging potential of RaaS attacks.
Preventing Ransomware-as-a-Service Attacks
Recovering from a ransomware attack can be a daunting and costly endeavor. Therefore, organizations must prioritize prevention to avoid falling victim to RaaS attacks. Here are essential strategies to implement for effective prevention:
