DATA BREACH • PII/EPHI • DPDP ACT • 250 CRORE LIABILITY

Situation: The recent Ayushman Bharat data breach—where the PII (Personally Identifiable Information) and ePHI (electronic Protected Health Information) of millions of Indians was found exposed—is not just another data leak. It is the *first major test case* for India’s new Digital Personal Data Protection (DPDP) Act.

This is a decision-grade CISO and General Counsel brief. The “250-Crore” (₹250,00,00,000) question is no longer *if* you will be breached, but *what* your liability is when you are. This breach was a simple Broken Access Control flaw. It exposes your company to *both* reputational *and* massive financial ruin under the DPDP Act. We are dissecting the TTP and the *new* C-suite legal liability.

TL;DR — The Ayushman Bharat leak (a simple access control flaw) is a “warning shot” for every CISO.

  • The Flaw: A Broken Access Control vulnerability (e.g., an unauthenticated API endpoint) exposed the PII/ePHI of millions.
  • The Legal Nightmare (DPDP Act): This breach makes you, the “Data Fiduciary,” liable for *failure to implement reasonable security safeguards*. The penalty? Up to ₹250 Crore.
  • The “GC’s Nightmare”: Unlike GDPR, the DPDP Act is simple. The question is: “Did you leak PII?” Yes. “Did you have *reasonable* safeguards?” No. The fine is *not* a percentage of revenue; it’s a *massive* flat penalty.
  • The Threat: Your own custom apps, SaaS/CRMs (like Salesforce), and third-party vendors are *all* vulnerable to this *exact* flaw.
  • THE ACTION: 1) MANDATE a Web Application VAPT (Penetration Test) on *all* PII-handling apps. 2) HUNT for anomalous data access (MDR). 3) DEPLOY *Session Monitoring* to stop the *result* of a breach.

Phase 1: The “250-Crore” Hammer (Why the DPDP Act Changes Everything)

For decades, data breaches in India were a PR problem. Under the new Digital Personal Data Protection (DPDP) Act, they are a *financial catastrophe*. The Ayushman Bharat case is the perfect, terrifying example.

Here’s what every CISO and General Counsel (GC) *must* understand:

  1. You are the “Data Fiduciary”: If you “determine the purpose and means of processing” PII, you are the Fiduciary. You are 100% liable.
  2. The “Reasonable Safeguards” Clause: The Act mandates that you *must* implement “reasonable security safeguards” to prevent a breach.
  3. The 250-Crore “Hammer”: The penalty for failing this duty is *up to ₹250 Crore* (approx. $30 Million USD). This is a *crippling* fine designed to put companies out of business.

The Ayushman Bharat breach was a simple access control flaw. An API endpoint was left unauthenticated. This is *not* a sophisticated 0-day. This is a *common, preventable* bug.

When the Data Protection Board of India investigates, the conversation will be simple:
Board: “Was customer PII/ePHI leaked?”
CISO: “Yes.”
Board: “Was this a complex, unpreventable 0-day?”
CISO: “No, it was an unauthenticated API. A basic VAPT would have found it.”
Board: “So you *failed* to implement ‘reasonable security safeguards’.”

This is the General Counsel’s nightmare. The case is open-and-shut. This is not a “risk”; it’s a *liability*. Your *entire* security budget is now an exercise in *proving* you took “reasonable safeguards.”

The CISO’s Mandate: Your *only* defense is “Proof of Due Diligence.” You *must* have an auditable, third-party paper trail. This is why our Web Application VAPT (Penetration Test) service is no longer “optional.” It is a *mandatory legal defense* that *proves* you took “reasonable safeguards” by hunting for these exact flaws.

Phase 2: The Kill Chain (How the Ayushman Bharat Flaw Works)

This was not a “hack.” This was an *architectural failure*. The attackers didn’t “break in”; they *walked in* the open door. This TTP is known as Broken Access Control (OWASP Top 10).

Stage 1: Reconnaissance (The “Shadow API”)

The attacker finds a “forgotten” API endpoint. Your developers created `https://api.yourcompany.com/v1/getUserDetails` for a mobile app, and it’s *still active*.

Stage 2: The Exploit (The “Unauthenticated” Flaw)

The attacker discovers this endpoint is *unauthenticated*. The developer (or a misconfigured Cloud API Gateway) *forgot* to check for a valid session token.
The attacker simply runs a script:

`curl “https://api.yourcompany.com/v1/getUserDetails?id=1″`
`curl “https://api.yourcompany.com/v1/getUserDetails?id=2″`
`…`

This is an IDOR (Insecure Direct Object Reference) flaw. The server “helpfully” returns the PII/ePHI for *every user*, one by one.

Stage 3: Data Exfiltration (The “4TB Question”)

The attacker scrapes your *entire* PII database (millions of records) in a few hours. This is a “low-and-slow” attack that your EDR/DLP, looking for a *single 10TB transfer*, will miss entirely. It just looks like “normal” API traffic.

The PII (Aadhaar numbers, names, addresses, health records) is now on the Dark Web. You are now the “Harrods” or “Qantas” breach. And you are now facing a ₹250 Crore fine.

Phase 3: Your *Real* Attack Surface (From SaaS to “Shadow APIs”)

As a CISO, your first thought is: “We don’t run Ayushman Bharat.” You are missing the point. *You are running the exact same vulnerability.*

Your “Ayushman Bharat” is:

  • Your Salesforce/CRM: Have you audited the *access controls* on your supplier-facing “Experience Cloud” portal?
  • Your Custom Web App: Is that “forgotten” v1 API from 2019 *still active* and unauthenticated?
  • Your SaaS Environment: Is your M365 or Google Workspace “Anyone with the link can view” setting exposing internal PII?
  • Your Cloud Infra: Is your Alibaba Cloud / AWS S3 bucket *publicly accessible*? This is the *exact* same flaw.

The CISO Mandate: You CANNOT trust your internal dev teams.
You *must* assume they are creating “Shadow APIs” and “Broken Access Control” flaws. Your *only* defense is a *mandatory, continuous* Vulnerability Assessment and Penetration Test (VAPT) program.

You *must* have an *external* team (like CyberDudeBivash) whose *only job* is to hunt for these “open doors.” This is not a “nice to have”; this is your *primary legal defense* for the DPDP Act.

The CISO/GC Mandate: The “Audit, Hunt, Respond” Plan

You cannot “patch” this. This is a *process* and *architecture* failure. This is your new 3-step mandate.

1. AUDIT (The “VAPT Mandate”)

You *must* find the “open doors” before attackers do.

  • Mandate VAPT: All *existing* PII-handling apps get a full VAPT *this quarter*.
  • Mandate “Secure by Design”: All *new* apps *must* pass a Secure Code Review and VAPT *before* going to production.

Training is not optional. Your developers are creating these flaws. You *must* train them in Secure Coding. We use Edureka’s “Secure Coding” and “Web Security” courses to train our clients’ dev teams.

2. HUNT (The “MDR Mandate”)

You *must* assume a breach. Your *only* defense is to find the “low-and-slow” exfiltration. This requires a 24/7 human MDR team to hunt for *behavior*:

  • “Why is one IP address making 10,000 *sequential* API calls to `getUserDetails`?”
  • “Why is our `java.exe` (SAP/Web) server spawning a `powershell.exe` shell?”
  • “Why is our web server making an *outbound* connection to an unknown IP?” (a C2 beacon).

3. RESPOND (The “Session” Defense)

What if the attacker *does* steal a valid admin cookie? This flaw is often chained with Session Hijacking.
Your *final* layer of defense *must* be Behavioral Session Monitoring.
Our SessionShield app is designed for this. It “fingerprints” your *real* admin’s session. The *instant* an attacker “hijacks” that session from a new, anomalous location, SessionShield *kills the session*. This stops the breach *after* the initial exploit.

You need a layered defense. Here’s our vetted stack for this specific threat.

Alibaba Cloud (WAF)
This is your *best* mitigation. A cloud WAF can provide a “virtual patch” to *block* these anomalous API requests *before* they hit your server.Kaspersky EDR for Servers
This is your *hunter*. It’s the *only* tool that will see the *post-exploit* behavior (like `apache -> bash`) that your firewall will miss.Edureka — Secure Coding Training
This is a *developer* failure. Train your devs *now* on how to write secure code and *never* allow unauthenticated API access.

TurboVPN
Lock down your *admin* portals. They should *never* be on the public internet. *Only* accessible via a trusted admin VPN.AliExpress (Hardware Keys)
Protect your *admin accounts*. Use FIDO2/YubiKey for all privileged access to your EDR and cloud consoles.Rewardful
Run a bug bounty program. Pay white-hats to find these simple, critical flaws before attackers do.

FAQ

Q: What is the DPDP Act?
A: The Digital Personal Data Protection (DPDP) Act is India’s new data privacy law. It functions like GDPR. It makes *you*, the “Data Fiduciary,” financially liable (up to ₹250 Crore) for *any* breach of PII that occurs from a failure of “reasonable security safeguards.”

Q: What is “ePHI”?
A: Electronic Protected Health Information. This is the *most sensitive* PII (medical records, diagnoses, patient history). The Ayushman Bharat breach leaked this, making it a critical event.

Q: What is “Broken Access Control”?
A: It’s the #1 vulnerability on the OWASP Top 10. It’s a flaw where an attacker can simply *access* things they shouldn’t be able to, without any complex “hacking.” An unauthenticated API or an IDOR (e.g., `view_record.php?id=123` → `id=124`) are the most common examples.

Q: What’s the #1 action to take *today*?
A: Get an audit. You *must* assume you have “Shadow APIs” and “Broken Access Control” flaws. You *must* have a paper trail proving you tried to find them. Call our team to schedule a Web App VAPT. It’s no longer just a “security” task; it’s a *legal* and *financial* imperative.
