Popular Messenger Users’ Data Leaked and Students' Personal Information Exposed
05.12.2023

 There is no respite for us, as information security incidents continue to occur. It's time for us to once again report on two recent notable data leaks.

Let's start with a recent major incident, which affected users of one well-known messenger. LY Corporation, a major Japanese internet company and owner of the popular Line app, experienced an incident that resulted in the leak of approximately 440, 000 items of personal data, including those of Line messenger users.
 
The leak was the result of unauthorized access to the subsidiary's computer system in the end of October. It took the company a month to determine the extent of the incident.

The leak affected LY's customers, partners and employees. An official statement of company representatives about the incident claims, that the following data was leaked:

  • Age group of Line users
  • Genders of Line users
  • Service use histories of Line users
  • Full names of employees and partners
  • Identification numbers of employees
  • Email addresses of employees and partners.

Allegedly, 300,000 Line app users, 86,000 LY partners and 51,000 LY employees had their data leaked. According to the company spokesman, no cases of the exposed data misuse have been reported.

As a result of the second incident, large trove of personal details was leaked. Appscook Technologies, an Indian company that develops apps used by hundreds of schools in India and Sri Lanka, exposed around one million confidential files due to misconfigured systems. The point was that the company's storage bucket was available to anyone who was willing to make use of it.

The company's applications aim to organize online learning and provide a communication link between parents and schools regarding children's progress. Thus, most of the leaked information belonged to minors, posing a significant threat to their safety.

Allegedly, the incident revealed the following information:

  • Full names of students
  • Full names of parents
  • Pictures of students 
  • Names of the schools children attend
  • Birth certificates
  • Fee receipts
  • School performance information
  • Home addresses
  • Phone numbers.

The leak was discovered by Cybernews researchers, who contacted Appscook representatives but, according to Cybernews, haven't received a response.


Not so long ago, we also reported on the Southern Association of Independent Schools incident. At that time, due to an unprotected password-protected database, student health information, financial reports, and even school security reports became publicly available.
