According to the prosecutor's office, the hacker attack on October 11 hit large supermarket chains.

As a result of the attack, "the food spoiled significantly and about 20 fires broke out."
In a statement on Monday, the Paris prosecutor's office said its cybercrime unit had opened a judicial investigation into charges that include "fraudulently interfering with an automated data processing system and causing harm by dangerous means to people, both crimes committed as part of an organized group."
On Monday, Iranian authorities did not immediately respond to statements by French prosecutors.
