Where to Report if You've Been Hacked? A Collection of Official Response Agencies

How to Submit Reports According to Purpose: Crime Investigation, Technical Response, Personal Information, and Financial Damage

If you experience hacking damage, it can be confusing to know whether to first contact the police, KISA, personal information organizations, or financial companies. Each agency has different roles, so reporting to one agency doesn’t mean that account recovery, crime investigations, personal information disputes, and payment suspensions will all be handled automatically. It's important to categorize the type of damage and the required actions when submitting reports.

If you want a crime to be investigated and punished, reporting to the police is crucial, while technical responses to intrusions of private information systems should go through KISA. If personal information has been leaked or misused, you should look into the personal information infringement reporting and dispute resolution procedures. If there were any account transfers or card payments, you must immediately contact the financial institution separately from reporting.

Before making a report, preserve links, screen captures, account notifications, transaction records, conversations with others, and the time of occurrence as close to the original as possible. Do not directly contact those suspected of being perpetrators or assume identity solely based on an IP address.

This list organizes the official agencies available in the country and their roles. There may be follow-up procedures, such as visiting the police station after online submission, so it’s important to read the latest guidance on the submission screen to the end. In the case of threats to life or body or ongoing crimes, contacting emergency reporting at 112 takes precedence over online complaints.

Cyber Crime Reporting System ECRM

Cyber Crime Reporting System ECRM is an official function or service that can be used to report, consult, or provide information on cyber crimes like hacking and fraud online. Rather than judging by the name alone, it’s essential to first verify the operating entity and the official domain.

When you’ve experienced a real crime that requires criminal punishment, calmly check the recent records and guidance on the reporting screen, and capture details of unfamiliar items such as time, device, and location. If recovery or reporting is necessary, this record can serve as the material that explains the situation.

After online submission, confirm if a visit to the police station or additional statements are required. Do not use this service to test other people's accounts or systems, and only utilize it within the scope of your own property or with explicit permission.

This is not a general security consultation number, so clearly describe your current risk and location. Do not use this service to test other people's accounts or systems, and only utilize it within the scope of your own property or with explicit permission.

Criminal investigations or financial payment suspensions should be requested separately from the police and financial companies. Do not use this service to test other people's accounts or systems, and only utilize it within the scope of your own property or with explicit permission.

Personal Information Infringement Reporting Center is an official function or service that provides personal information infringement consultation and reporting procedures. Rather than judging by the name alone, it’s essential to first verify the operating entity and the official domain.

If you believe that personal information has been collected, used, provided, or leaked without authorization, calmly check the recent records and guidance on the reporting screen, and capture details of unfamiliar items such as time, device, and location. If recovery or reporting is necessary, this record can serve as the material that explains the situation.

Criminal investigations and claims for damages or dispute resolution may require separate procedures. Do not use this service to test other people's accounts or systems, and only utilize it within the scope of your own property or with explicit permission.

If recovery or reporting is necessary, this record can serve as the material that explains the situation.

First, confirm the application requirements, required evidence, and the relationship with other remedies. Do not use this service to test other people's accounts or systems, and only utilize it within the scope of your own property or with explicit permission.

By first clarifying the purpose of your report, it becomes easier to choose the right agency. Requests for criminal investigations, technical support to prevent system proliferation, remedies for leaked personal information, and freezing any money that has already been lost are all different procedures. If one incident spans multiple areas, you may need to submit reports to related agencies individually.

Completing online reporting doesn’t mean all procedures are finished. The police ECRM may require you to visit a police station and provide a statement depending on the type of incident, and enterprises may have separate legal reporting deadlines to adhere to. Keeping a list of your submission number, the responsible agency, call times, and submitted materials will facilitate follow-up inquiries.

It's important to maintain authenticity and chronological order when collecting evidence rather than gathering large quantities. Do not re-edit messages or repeatedly run infected files; preserve screens, file names, and transaction times as they are. Only provide sensitive information like identification cards or authentication numbers to the official submission screen of the agency confirmed as requiring it.

Let’s take measures to prevent the spread of damage along with making reports. Depending on the situation, this includes ending account sessions, contacting financial companies, disconnecting connected devices, and changing passwords.
