Ransomware-as-a-Service (RaaS) is a criminal business model where malware developers ("operators") build and maintain ransomware toolkits, then rent or franchise them to "affiliates" who run the actual attacks in exchange for a cut of the ransom — typically 70-80% to the affiliate, the rest to the operator. This division of labor, borrowed straight from legitimate SaaS economics, means an attacker no longer needs coding skill to launch a ransomware campaign — only access to a target network, often bought from a separate criminal specialist called an initial access broker. For Indian businesses, RaaS is the reason ransomware attacks have become more frequent and less predictable: the barrier to entry has collapsed.
What Ransomware-as-a-Service actually means
Traditional ransomware required one group to write the code, find the target, breach the network, deploy the payload, and negotiate the ransom — a slow, skill-intensive pipeline. RaaS breaks that pipeline into specialized roles, the same way cloud computing broke "run your own datacenter" into rentable infrastructure.
- Operators build and maintain the ransomware — encryption logic, a leak-site for published victim data, negotiation chat infrastructure, and often a dashboard where affiliates track active infections.
- Affiliates rent access to that toolkit and do the actual break-in and deployment, keeping the majority of any ransom collected.
- Initial access brokers (IABs) are a third, separate specialism — criminals who compromise networks (via phishing, stolen credentials, exposed remote access) and sell that access on dark-web forums to whichever affiliate is buying, with no involvement in the ransomware deployment itself.
The RaaS operating model
Notice the two entry points feeding the same attack chain — an affiliate can rent the toolkit directly from the operator, or buy pre-existing network access from an initial access broker who has never touched a ransomware binary. Both paths converge at deployment, which is why defending only against "known ransomware" and ignoring the earlier access-broker stage leaves a wide gap.
Why this lowers the barrier to entry
Before RaaS, running a ransomware campaign required genuine technical capability: writing or modifying encryption malware, evading antivirus, and managing command-and-control infrastructure. RaaS platforms package all of that into a rentable kit with documentation, a support channel, and sometimes a dashboard — the same onboarding experience as a legitimate B2B SaaS product. An affiliate needs three things: a way to get initial access, willingness to negotiate with a victim, and a share of the payout to hand back to the operator.
This has three consequences that matter for defenders:
- More attackers, not just more attacks. The pool of people capable of running a ransomware campaign has expanded from a small set of skilled malware developers to anyone willing to buy access and rent a kit.
- Faster iteration. Operators compete for affiliates the way SaaS vendors compete for customers — improving evasion, encryption speed, and negotiation tooling to attract more affiliates and therefore more attacks using their brand.
- Attribution gets harder. Because the same toolkit is used by many unrelated affiliates, and access is bought from yet another separate party, tracing an attack back to a single accountable group is often impossible — complicating both law enforcement response and a victim's own incident narrative.

Early ransomware simply encrypted files and demanded payment for the decryption key. RaaS-era attacks have layered additional pressure points on top:
- Single extortion: Encrypt data, demand payment for decryption.
- Double extortion: Exfiltrate data before encrypting it, then threaten to publish it on a leak site if the ransom isn't paid — defeating the defense of "we have clean backups, so we don't need to pay."
- Triple extortion: Add a third pressure layer — contacting the victim's customers, partners, or regulators directly, or launching a distributed denial-of-service (DDoS) attack against the victim's public-facing systems to force negotiation.
Common initial access vectors
These proportions are illustrative of the categories consistently reported across industry ransomware research (including Sophos's annual State of Ransomware survey) rather than a single precise figure — the exact split shifts year to year and by sector, but phishing, exposed remote access, unpatched software, and stolen/reused credentials remain the four dominant entry points across nearly every published analysis.
What this means for Indian businesses
RaaS affiliates do not need to specifically target India to hit Indian companies — many operate opportunistically, scanning broadly for exposed remote access, unpatched internet-facing software, or successful phishing hits, and only then checking who the victim is. That means sector and size are far weaker predictors of risk than exposure: an unpatched VPN appliance or an internet-facing RDP port is an equally attractive target whether it belongs to a bank or a 40-person exporter.
| Defense control | What it addresses | Why it matters against RaaS specifically |
|---|---|---|
| MFA on all remote access (VPN, RDP, email) | Exposed RDP/VPN, stolen credentials | Blocks the two most common initial-access vectors used by affiliates and IABs |
| Offline, tested backups | Encryption stage | Removes leverage for single-extortion, though not double/triple |
| Network segmentation | Lateral movement post-breach | Limits how far an affiliate can spread after one system is compromised |
| Email filtering + phishing-awareness training | Phishing / social engineering | Cuts off the single largest reported entry vector |
| Continuous vulnerability scanning + patch cadence | Unpatched vulnerabilities | Closes the window IABs specifically scan for and sell access to |
| Exfiltration/DLP monitoring | Double/triple extortion | Detects data leaving the network before the encryption stage even begins |
| Documented, tested incident response plan | Response speed | Reduces dwell time, which affiliates need to complete exfiltration and encryption |
Building a practical defense posture
Given the modular nature of RaaS, a layered defense that assumes attackers can be specialists at any single stage — but rarely at all of them — is the most realistic posture for Indian SMBs and mid-market firms:
- Close the vectors initial access brokers sell most: exposed RDP/VPN, unpatched internet-facing software, and phishing-susceptible email.
- Enforce MFA everywhere remote access exists — this alone removes a large share of stolen-credential access attempts.
- Run continuous vulnerability scanning rather than annual point-in-time audits, since IABs scan continuously and a patch gap of even a few weeks is a viable sale.
- Segment networks so a single compromised endpoint cannot reach backup infrastructure or domain controllers.
- Monitor for data exfiltration, not just encryption — by the time files are encrypted, the double-extortion leverage is often already established.
- Maintain offline, regularly tested backups, and rehearse the restore process before an incident, not during one.
- Document and rehearse an incident response plan that includes legal, communications, and regulatory notification steps — under India's DPDP Act, a breach involving personal data carries its own notification obligations independent of the ransom decision.
If you haven't assessed your external attack surface recently, a free VAPT scan is a fast way to check whether an exposed RDP/VPN port or unpatched service is currently sitting on a broker's shelf, and Indian businesses handling personal data should also review the DPDP compliance guide for the notification obligations that apply if a ransomware incident involves a personal-data breach.
