Sensitive Details of Over 200 Million Indonesian Residents Allegedly Leaked

On May 12, 2021, a Threat Actor (TA) named “kotz” posted on a cybercrime forum, claiming to have data for over 200 million residents in Indonesia. The leaked data includes personally identifiable information (PII) of residents, but no passwords were leaked; it appears that the source might be from government surveys.

On further investigation, Cyble researchers found that the leaked data contains information about the user such as First Name, Last Name, Date of Birth, Mobile Number, Email ID, National Identity Numbers, and annual salaries for some of the individuals.

Our intelligence sources suggest that it affects over 200 million Indonesian citizens and foreigner who has worked in Indonesia for at least six months. The perpetrators allegedly gained access to the network of one of the legal bodies. This is unconfirmed at this stage.
