A 17-year-old boy and a 22-year-old man were arrested by the police investigating Kiberataku in the kindergartens network in London.
The metropolitan police reports that the couple was arrested at the address of residence in Bishops Stortford, Hartfordshire, on suspicion of an abuse of a computer and blackmail.
It is reported that hackers stole photographs, names and addresses of about 8,000 children from the KIDO network.
Forces stated that on September 25, they received a direction from the service of Cybercrime Action Fraud with a detailed description of the attack using the Mount Program.
The detainees are in custody for interrogation.
Will Line, the head of the MET economic and cybercrime department, said: “We understand that messages of this kind can cause serious concern, especially among those parents and guardians who may be concerned about the influence of such an incident on them and their family.
“These arrests are a significant step forward in our investigation, but we continue to work with our partners in order to ensure the prosecution of those responsible for justice.”
Kiberataka for the Kido nursery for the first time attracted the attention of BBC on September 22, when hackers who call themselves Radiant tried to attract the attention of the press to the theft of data as part of their attempts to extort about 600,000 pounds in Bitcoins from the nursery network.
BBC did not report hacking until September 25, hackers began to publish images and profiles of some children on their website in the Darknet that cyber sequperts called the “new minimum” of cybercrime.
The stolen data included the names, addresses and photographs of children, as well as the contact details of parents and guardians.
Hackers directly called their parents about their hacking to force Kido to pay a ransom for removing data. More children's profiles were added, as a result of which the total number reached 20.
Hackers took an unusual step, then blurred the images, as they were concerned about their reputation among other hacker groups.
Then on October 2, they deleted all the stolen data and photos from their site in the darknet and stated that they deleted all 8000 children's files. “Nothing else is left, and this can console the parents,” they said.
The KIDO representative confirmed that the company “revealed the cyberurine and responded to it” and worked with external specialists on the investigation and finding out what happened.
They added: “We quickly informed both our families and the relevant authorities.”
