South Korea's National Police announced the arrest of four people allegedly behind one of the country's largest surveillance hacking cases. According to authorities, the suspects illegally gained access to more than 120,000 IP cameras installed in private homes and businesses, then distributed the stolen footage via a foreign adult content website .

Although the police have not revealed the identities of those arrested or the name of the platform that hosted the illegal videos, international agencies are already collaborating to identify the website administrators and the viewers who watched the material.
The official Police statement
A statement from the National Investigation Service states that the four arrested "hacked over 120,000 IP cameras and sold the recorded material on an illegal website abroad." At the same time, as it is emphasized, in addition to the platform administrators, investigations are also underway against the buyers or viewers of the material, while protective measures are being taken to limit further leakage and harm to the victims.

The actions of the four suspects

- Suspect C (office worker): Hacked 70,000 cameras and sold 648 videos, earning 18 million KRW ($12,300).
- Suspect D (self-employed): He hacked 15,000 cameras and allegedly produced content that also includes minors — an element that dramatically elevates the seriousness of the charges.
- Suspect E (office worker): Linked to 136 violations. Authorities are investigating whether some cameras were hacked multiple times by multiple perpetrators.
According to the researchers, suspects B and C alone were responsible for 62% of the total material uploaded to the illegal website in the previous year, which demonstrates their systematic and extensive activity .

Spectator arrests and international cooperation
The police did not limit themselves to the perpetrators who produced the material. Three buyers of the illegal videos have already been arrested, who could face prison sentences of up to three years.
