French authorities said they were able to link Iran's Shahid Kaveh group to the hacks.
On 2 November, grocery stores across at least nine other European countries were hit by a suspected cyberattack.
France has alleged that Iran's Revolutionary Guards were behind "unprecedented" cyber attacks on supermarket fridges in the country last month, vowing sanctions on a European level against Tehran.
Swathes of French supermarkets were hit in the 11 and 12 October cyber attacks , which raised the temperatures in their refrigerators, in some cases forcing them to throw away entire inventories of perishable food.
"I can confirm that this attack was carried out by the Islamic Revolutionary Guard Corps (IRGC) of the Islamic Republic of Iran," foreign minister Jean-Noël Barrot said of the cyber attacks.
"This attack is unprecedented in both its scale and its level of aggression," he said on the sidelines of the G7 foreign ministers' meeting in Paris on Tuesday AEDT.
The Paris prosecutor said in a separate statement she had opened an investigation into Shahid Kaveh, a shadowy cyber unit of the IRGC, Iran's ideological army, over the attacks.

"It marks the first large-scale cyber attack aimed at sabotage on our national territory, and it constitutes a major attack on the nation's interests and the security of the French people," said Barrot.
"We will implement sanctions at the European level against all those responsible," he added.
Iranian officials have not publicly commented on the French allegations.
Barrot only directly referred to attacks against French supermarket systems, which he said targeted 700 sites.
However, similar incidents have been reported in other European countries.
On 2 November, grocery stores across at least nine other European countries were hit by a suspected cyber attack on their freezer systems.
The incidents have shaken Europe at a time when officials have warned of the risk of cyber attacks from Russia as European countries press support of Ukraine in its war against Moscow.
In recent days, European air traffic has also been disrupted by false bomb alerts against dozens of flights, although the origin of those threats has yet to be made clear.
The United States and Israel started a war against Iran on 28 February by killing the country's supreme leader, Ali Khamenei.
European countries did not get involved in that conflict, but French officials have accused Iran of spreading misinformation related to the protests that have rocked France over the past month.
How did the hacking take place?
Paris prosecutor Laure Beccuau said in a statement that a judicial investigation had been opened against the head of Shahid Kaveh and his two deputies.
She described the entity as "an offensive cyber unit affiliated with the Electronic and Cyber Centre of the Islamic Revolutionary Guard Corps (IRGC-CEC)".
Little is known the Shahid Kaveh unit, although analysts have long observed that the IRGC, which has a vast network of operations, had actively branched out into cyber warfare in recent years.
Beccuau did not name the three individuals targeted in the investigation.
"A hallmark of this unit's modus operandi is the use of the Persian language and IP addresses that trace back to terminals located in Iran," said the Paris prosecutor.
She said attackers had taken control of the equipment remotely via web interfaces "to initiate abnormal, indefinite defrost cycles".
Meanwhile, security alerts from sensors designed to go off when temperatures exceeded a certain threshold were "simultaneously disabled", she added.
Barrot said France had summoned the Iranian ambassador to Paris "to lodge a very strong protest against this extremely grave act".
"We will take any other necessary and proportionate measures — whether public or otherwise — to respond to this incident and deter anyone who might seek to repeat it," he added.
Speaking after Barrot, EU foreign policy chief Kaja Kallas said "our response should be strong", adding she had just learnt of the attribution of the attack to Iran.
