k As part of an attempt to cope with the spread of the corona virus, authorities began to use technological means that allow the retroactive telephone retrieval of contractors to identify their course in the days before the onset of symptoms and to instruct those in their vicinity to enter the isolation. But Israelis quickly emerged looking for a way to avoid such surveillance.

Many citizens have begun to move their smartphone into flight mode and even leave without it while staying outside their home. Remember, hundreds of Israelis have recently received messages from the Ministry of Health as having come in contact with Corona patients following their cellphone pickup - and have been asked to enter the 14-day isolation.

One of the Israelis referring to the new method wrote on his Facebook page, "Everyone I know goes out of the house with a mobile off or on a flight mode, otherwise we will find ourselves with arbitrary isolation orders." In another post posted on Facebook that went viral, it says: "Put on flight status and then the dictatorship will not be able to follow us." Another Israeli who is apparently back from abroad, Story posted on Instagram where he showed followers that he had left home and put the smartphone into flight mode.

So can this method really prevent you from getting the message from the Ministry of Health? The answer is unequivocal. "We don't know everything, but it probably works by accessing cellular antennas and actually lets you see by phone numbers who connected to the same cell at the same time, and thus finding out who was next to a sick person in Corona," says Idan Stambolchik, head of attack development team In the acrylic, "technically, if we reach a situation where a person puts the smartphone into flight mode, there is a chance that he will be able to evade the same regional spelling because he did not contact the same cell, which means that the ISA will not be able to locate the phone number. His being in the same location. On the technical level it can work. But tell you if it can work 100 percent of the time - there's no telling. They don't reveal too much information about the tools and there's a reason for that. "

On the other hand, some think that a flight situation will not save you from the isolation at all. "In my estimation, transferring to a flight situation could possibly prevent the police from following up, but not from the ISA," said Advocate Jonathan Klinger, attorney general for the Digital Rights Movement. "The ISA has the authority to obtain data from any technology system by law, from looking at security cameras and through information requests from Google."

Klinger adds that "the ISA has the legal tools, I don't know if they have the technological tools. According to the regulations, they are allowed to contact anyone and receive the information from them, including let us contact you and ask you for an IP address from the readers. "

We contacted the ISA for a reference, but there they refused to comment
