The Times of Israel reports: “Iranian hacker group Handala infiltrated panic buttons in some 20 kindergartens Sunday morning, using the systems’ loudspeakers to broadcast rocket sirens and Arabic songs supportive of terrorism.

The systems, run by electronics firm Maagar-Tec, were disconnected, and the company said it was looking into the incident. The matter was also referred to the National Cyber Directorate.

Using another of the same company’s systems, Handala also sent intimidating text messages to tens of thousands of people, the Directorate said, adding that the messages posed no danger and that recipients should simply block the sender.

Handala also claimed to have broken into the National Security Ministry’s command and control system, and stolen from the ministry’s servers four terabytes of internal communications, video recordings, confidential documents and personal records of all police officers and firefighters.

The hacker group posted pictures that appeared to show a control panel for bomb shelters in central Israel, registrars of local police forces’ vehicles, police officers with their weapons, and civilians’ private gun licenses…”
