Die Wörter, die die japanische Polizei in den sozialen Medien untersucht, um die Rekrutierung von Online-Kriminellen zu bekämpfen

Since several months, Japan is facing a brand new type of crime. Social networks are used to recruit people with no criminal records for odd jobs. However, these individuals end up being forced into committing crimes.

In the Japanese media, the word “yami baito “has appeared everywhere in the past few weeks. “Yami”, means dark, and “baito”,work but in the context of a small task. “yamibaito” could be translated to shadow work. Some criminals are not even located in Japan. They post job ads for easy, well-paid jobs on social media networks such as X, Signal, or Telegram. They never mention that they are committing a criminal act. The mission is to move suitcases or parcels from one locker at a major station to another, or collect money from an elderly woman’s home. Protected messages are used to give these seemingly innocent missions. The person giving the order is never seen. The suitcase may contain drugs or other stolen items, while the granny who gave you the money was previously conned. It’s then a matter of escalated crime.

Blackmail by criminal networks

They encourage their employees, who are often shadowy figures in the network to continue committing crimes. Since they already know the addresses of their recruits, and sometimes their parents’, when young, as well, they can use blackmail to force them into committing further crimes. They then launch more violent attacks. Recently, there have been several robberies in Tokyo of stores selling second-hand luxury items. The young people had never met before, but they all met up at the same place to attack an antique store. The same order had been sent to them all on Signal.

Police have been looking into a number of “saucissonnages”, or violent attacks, near Tokyo since September. In mid-October, a 75-year old man was found dead at his Yokohama home. The man had been tortured and tied up. Investigators suspect that these suspects were also recruited from a distance for these “yamibaio”.

The police, in response to the increase of these crimes, have hired artificial intelligence experts to develop a program that can read all messages posted on social media to detect job offers considered suspicious. It tracks X, or comments on YouTube videos in order to detect possible cases.
