Cyberattaque against Auchan, Bouygues Telecom, Orange, Doctolib, Air France … How to fight the explosion of data flights

The announcement. Therefore, Thursday, by Auchan of the theft of personal data from several hundred thousands of loyalty accounts illustrates the trivialization of a now massive phenomenon: the multiplication of cyber attacks targeting French economic and institutional actors. Moreover, Names, first names, postal and electronic addresses, telephone and loyalty cards are part of the stolen information. However, The group ensures that banking data and passwords are not affected and that the incident has been circumscribed. For example, But this episode. cyberattaque against auchan, bouygues telecom, However, which occurred a few months after a similar attack in November 2024, recalls how much the digital security of the big brands remains fragile.

The Auchan case is added to a list that continues to lie down. In early August, more than six million Bouygues Telecom customer accounts were compromised, with leaks including bank details this time. Doctolib underwent an intrusion in June having exhibited 2.6 million medical profiles. Orange, Free and SFR or Air France have also seen several hundred thousands of their affected subscribers. Local communities. hospitals and administrations are not spared: the Simone Veil de Cannes Hospital was paralyzed in 2024 by a ransom, and the Family Allowance Fund had to face a large -scale compromise.

The figures give the measurement of the phenomenon: in 2024. near one in two French enterprise experienced a major cyber attack and 42 % of cyberattaque against auchan, bouygues telecom, them underwent a data theft, up eleven points compared to 2023. The average cost of a violation now reaches 3.59 million euros, with particularly affected sectors such as pharmacy, financial services or energy. These intrusions, less numerous but more targeted, lead to identity usurpations, financial losses and damage to reputation.

Sometimes not detected flights for weeks

To this intensification is added a qualitative mutation: the growing use of artificial intelligence by cybercriminals. Automation of flaws. discreet data exfiltration for several months, reinforced camouflage in the face of conventional defenses: AI makes attacks more stealthy and more difficult to counter. According to recent data, 67 % of data flights in 2023 have remained undetected for more than a hundred days. But artificial intelligence can also become an asset for defenders. by strengthening the productivity of operational security centers, prioritizing alerts and identifying abnormal behavior impossible to cyberattaque against auchan, bouygues telecom, identify manually.

For the National Agency for Information Systems Security (ANSSI), awareness must be collective. “The Cyber ​​threat has become a social phenomenon. which requires society’s answers as a whole,” said The dispatch Last December its director, Vincent Strubel. The experience of the Olympic. Paralympic Games has shown that the joint mobilization of the State, companies and private operators could constitute an effective barrier. It is still necessary to prolong this dynamic.

The defense tracks are known: generalization of so -called “zero trust” architectures. where no access is granted by default, continuous monitoring of network behavior, reinforced by automated analysis, secure backups and regularly tested, team training and user awareness of phishing and false messages. So many levers which, combined with close cooperation between public and private, can slow down the climbing of cyber attacks.
