All four are charged with hacking internet-connected surveillance cameras, and two are charged with selling illegally filmed sexually exploitative material.
Distributing or selling pornography is largely illegal in South Korea. The charge of sexual exploitation is for taking footage of a person’s body against their will, Kim said.
Illegally filmed videos have been a major issue and catalyst for the feminist movement in South Korea – where authorities have cracked down on hidden cameras, known as “molka,” in public places such as swimming pools, hotels and public bathrooms.
One suspect is alleged to have been paid about US$24,000 ($41,000) worth of virtual assets in exchange for the stolen videos and another about US$12,000.
Authorities are also investigating the website operator and people who viewed the footage, the release added.
The hacked cameras were internet protocol (IP) cameras, network-connected cameras that are often cheaper than those that use an analogue closed-circuit system, but that can be less secure because data is transferred over IP networks such as those connected to home Wi-Fi.
The networks that had been broken into were protected with names and passwords that were “found to be simple, consisting of repeated characters or combinations of sequential numbers or letters”, the release said, calling for users of IP cameras to regularly change their passwords.
There have been numerous cases worldwide of IP cameras being hacked.
In Mississippi, the United States, in 2019, a man hacked into a Ring camera in a family home that was installed in a child’s bedroom and spoke to her, including repeatedly directing a racial slur at the child and trying to persuade her to misbehave, according to a copy of the video obtained by the Washington Post.
The family was among several users of the smart cameras nationwide who reported that year that their security systems were infiltrated by hackers who harassed them through Ring’s two-way talk function.
In those cases, the Ring users had set the same usernames and passwords on their accounts as had been exposed in a data breach of another service, the company said at the time.
