In a shocking development, a threat actor operating under the pseudonym “monkeycrazy” has claimed to possess and put up for sale the source code and critical infrastructure of Rupay, one of India’s leading banking and payment systems.
The announcement was allegedly made on a notorious dark web forum, raising alarms about the potential consequences of such a leak on financial security and digital transactions in the country.
Sensitive Data Allegedly Leaked
According to the post from ThreatMon, the alleged leak includes a treasure trove of sensitive files and tools central to Rupay’s operations.

According to the dark web post, the compromised codebase contains key components like “Gorunn API,” “Withdrawal Limit API,” “KYC Backend,” and even the “PayPal API.”
These APIs are reportedly integral to Rupay’s transaction management, customer verification processes, and payment gateway integrations.
Additionally, the threat actor claims the leaked data encompasses tools for wallet management, transaction orchestration, and backend frameworks.
Perhaps most alarming is the inclusion of production databases containing sensitive customer information such as identity documents and financial details.
If the claims hold, this could potentially expose millions of users to identity theft and financial fraud, jeopardizing trust in the banking system.
Expert Opinions Raise Concerns
Cybersecurity experts have expressed grave concerns over the potential ramifications of such a breach.
A leak of this magnitude, if verified, could paralyze Rupay’s infrastructure, disrupt financial transactions nationwide, and provide malicious actors with a blueprint to exploit vulnerabilities.
Prashant Kumar, a cybersecurity analyst, stated, “If Rupay’s entire infrastructure is indeed compromised, it could become a massive national security issue.
The stolen codebase could be used to replicate or compromise similar payment systems and even lead to a cascade effect in the fintech sector.”
Although there is no confirmation from Rupay regarding the veracity of the claims, the incident highlights the urgent need for robust cybersecurity measures.
Rupay’s Response and the Road Ahead
At the time of writing, Rupay has not issued an official statement addressing the alleged breach.
Speculation is rife that the organization may already be conducting an internal investigation to assess the scope of the potential compromise.
Industry watchers are urging Rupay to act swiftly and transparently to reassure customers and mitigate damages.
This incident underscores the growing risks in the digital payments sector, emphasizing the importance of securing critical infrastructures and fortifying defenses against increasingly sophisticated cyber threats.
