Japanese police have brought in, questioned, and charged a 13-year-old female student from the city of Kariya for sharing browser exploit code online.
The code was a mere prank that triggered an "unclosable" popup when users accessed a certain link, Japanese news agency NHK reported yesterday.
The popup could be closed in some browsers --such as Edge and Firefox on desktop-- but couldn't be closed in others, such as Chrome on desktop and the majority of mobile browsers.
The popup was hosted in several places online, and police say the teenager helped spread the links (archived page here --don't access on a mobile device).
The teenage girl did not create the malicious code, which had been shared on online forums by multiple users for the past few years.
NHK reported that police also searched the house of a second suspect, 47-year-old man from Yamaguchi, and are also looking at three other suspects for the same "crime" of sharing the link on internet forums.
