Key points

  • Modu-ui Changup platform suffered a data breach in July.
  • Encryption key exposed via API led to data disclosure.
  • 5,000 applicants' email addresses and startup ideas were leaked.
  • Incident highlights risks of hard-coding encryption keys.

Data Breach on Startup Platform

In July, Modu-ui Changup, a South Korean government-backed platform supporting startup programs, experienced a data breach. This platform is overseen by the Ministry of SMEs and Startups (MSS) and stores personal information, including startup ideas, email addresses, and names, for participants in a nationwide audition program.

Cause Identified: Exposed Encryption Key

Authorities confirmed on July 31 that the primary cause of the data leak was the exposure of an encryption key through an API. The leaked data, which included email addresses, evaluation comments, and summaries of startup ideas for about 5,000 successful applicants, was already encrypted. However, the exposed key allowed for its decryption.

How the Exposure Occurred

The Ministry of SMEs and Startups explained that the encryption key was included within the API. An external party collected API data, potentially through web crawling, which led to the key's exposure. Even email addresses configured as private were obtainable through AI-based web crawling, according to investigators.

Implications for Security Practices

This incident underscores the risks associated with hard-coding encryption keys directly into application code, configuration files, or databases. When keys are managed this way, they can become vulnerable to exposure alongside the systems or data they are intended to protect, compromising the security of otherwise encrypted information.
