Summary
SFR said a July cyberattack briefly exposed some fibre-internet customers' postal addresses, email addresses and phone numbers, though it did not disclose how many people were affected.
The breach hit a tool used to manage and analyze fibre connections; SFR said it cut access to the system immediately, added security measures and notified France's data watchdog CNIL.
Passwords and banking details were not compromised, but SFR warned affected customers to watch for phishing emails, texts and calls using their real contact information.
The disclosure adds to a broader French hacking wave after the tax office and land registry said up to 600,000 customers' details were stolen, and the Education Ministry was also breached.
Prime Minister Sébastien Lecornu has called an emergency meeting on cybersecurity as pressure grows over France's defenses against repeated attacks.
With French telecoms suffering massive breaches throughout 2025, what hidden vulnerabilities in internal tools are hackers exploiting to steal millions of identities?
SFR claims banking details were safe, but could the stolen contact data be the missing puzzle piece for devastating social engineering attacks?
Why did it take SFR over a month to notify customers of the breach, leaving millions vulnerable to highly convincing phishing scams?
