FreshMenu Data Breach 2024: Case Study

Technology Use-Cases Community
TL;DR: In response to the FreshMenu data breach, which compromised the personal data of over 3.5 million users, this article explores Hypersign's Encrypted Data Vault (EDV) as a robust solution for enhancing data security. Encrypted Data Vaults employ advanced encryption and blockchain technology to ensure secure data storage, selective data disclosure, and integrity. This approach makes sensitive data inaccessible and unreadable to unauthorized entities and provides a scalable and interoperable framework for data privacy. Companies seeking to protect user data and enhance privacy can turn to Hypersign for state-of-the-art security solutions, safeguarding their digital ecosystem against similar threats.


In light of the recent FreshMenu data breach, where over 3.5 million users' sensitive data was exposed, the need for robust data security measures is more evident than ever. Hypersign's innovative technology offerings, particularly the Encrypted Data Vault (EDV), present a promising solution to such vulnerabilities. This article delves into how Hypersign's EDV can prevent similar data leaks, ensuring the safety and privacy of user information.

The FreshMenu Data Breach: An Overview

Before discussing the solution, let's briefly recap the FreshMenu incident.
FreshMenu, a prominent food delivery service in India, due to a lack of password protection on a 26GB MongoDB database, exposed 3.5 million users' data, including names, emails, phone numbers, addresses, and IP addresses. The data was vulnerable for 2-3 days, enough time for threat actors to exploit the information for identity theft, phishing attacks, and more.

The Hypersign Solution: Encrypted Data Vault

Hypersign's Encrypted Data Vault (EDV) leads the charge in preventing data breaches. As secure repositories, EDVs store sensitive information in an encrypted format, ensuring access is possible only with the right decryption key. Notably, EDV mandates encryption of all data and metadata on the client-side while simultaneously allowing data storage across various devices and secure data sharing.
A key feature of EDV is its capacity to maintain data in a searchable and queryable state, even while encrypted. This capability highlights EDV's innovative approach to preserving data utility alongside security. Furthermore, EDV's compliance with the Digital Personal Data Protection Act, 2023. underscores its suitability as an essential tool for future privacy-focused products.

Use Cases of Encrypted Data Vault (EDV)

  • Secure Data Storage and Usage: EDV allows users to store their data in a highly secure environment. The data is encrypted in such a way that only the user can view and utilize it, ensuring that storage providers cannot access any of the stored data.
  • Data Searchability: With EDV, users can store substantial amounts of data and efficiently search through it. This feature is particularly important as it allows users to find specific data quickly while ensuring that the service provider remains unaware of the contents or the nature of the searches.
  • Selective Data Sharing: Users have the flexibility to share their data with other individuals or services. EDV provides a controlled environment where access to data is granted only upon the user's explicit consent for each item. Additionally, users can set expiration dates for third-party data access and have the ability to revoke access at any time.
  • Multi-Location Data Storage: EDV supports backing up data across multiple storage locations, enhancing data safety against potential failures. This includes a mix of local (e.g., on a phone) and cloud-based storage options. The system ensures automatic synchronization across all locations, keeping data up-to-date regardless of how or where it's updated.

Features of Hypersign's EDV

Robust Encryption

The core strength of Hypersign’s EDV lies in its sophisticated encryption protocols. Data stored in these vaults is encrypted, rendering it unreadable and unusable to unauthorized parties, even if they gain access to the storage system. Hypersign EDV currently supports various key algorithms like Ed25519VerificationKey2020, EcdsaSecp256k1VerificationKey2019, and the new BabyJubJubKey2021.

Selective Data Disclosure

Leveraging the BabyJubJub (BJJ) Key in its zero-knowledge Proof infrastructure, Hypersign allows for selective disclosure of data. This means that companies can allow users to reveal only the necessary information, minimizing the risk of data misuse.

Preventing Data Leaks: A Hypersign Approach

To understand how Hypersign's EDV could have prevented the FreshMenu leak, let's consider the following points:

Secure Data Storage

Hypersign's EDV would ensure all sensitive data is encrypted, making it useless to unauthorized parties who might access it.

Access Control

With blockchain integration, access control becomes more robust, preventing unauthorized access or tampering with the data.

Data Integrity

Blockchain's nature ensures the integrity of the data stored in EDVs, making it tamper-proof and secure.
The FreshMenu data breach is a stark reminder of the need for enhanced data security measures. Hypersign's Encrypted Data Vault offers a viable and robust solution to protect sensitive user data. By leveraging advanced encryption, blockchain technology, and user-friendly access through integrated wallets, Hypersign's EDV stands as a bulwark against the ever-growing threat of data breaches and cyber-attacks.
