In an alarming development for French internet users, the country’s second-largest Internet Service Provider (ISP), Free, experienced a significant data breach over the weekend. A group of unknown cyberattackers accessed critical subscriber information, putting the data of nearly 19 million customers at risk. This breach has intensified concerns over the security of personal data held by telecom providers. Here’s a deep dive into what happened, the details of the breach, and the implications for Free’s users and the broader ISP industry.
The Details of the Cyberattack on Free
Who Is Free?
Free, operated by the French telecom company Iliad, is one of the largest ISPs in France, with over 22 million customers. The company is widely recognized for its competitive mobile and fixed broadband services.
When Did the Breach Occur?
According to reports, the cyberattack took place over the weekend, with Free confirming the incident to Agence France-Presse (AFP) on October 26, 2024. The attackers reportedly accessed Free’s internal management system and obtained confidential data on its subscriber base.
How Did the Attack Happen?
A hacker, operating under the alias “drussellx,” managed to infiltrate Free’s internal systems, bypassing its security protocols. Once inside, the hacker retrieved sensitive data and later posted two databases on a dark web cybercrime forum, putting the data up for auction.
Data Compromised in the Breach
Extent of Compromised Information
The stolen databases are reported to contain:
- Personal data on over 19 million subscribers
- International bank account details of more than 5 million users
However, Free has assured customers that sensitive information such as passwords, SMS messages, bank card details, emails, and voicemails were not included in the breach.
Why This Breach Matters
For ISPs, protecting customer information is paramount, as they handle highly sensitive data, including home addresses, billing information, and personal identifiers. This breach highlights the growing sophistication of cyberattacks targeting ISPs.
Recent ISP Targeting by APT Groups
This breach follows a series of ISP attacks worldwide. Advanced Persistent Threat (APT) groups like Salt Typhoon and Evasive Panda have increasingly targeted ISPs, seeking customer data to exploit through phishing and other malware campaigns.
Free’s Response to the Data Breach
Immediate Actions Taken by Free
Free has stated that it is actively investigating the breach and has reported the incident to France’s National Commission for Information Technology and Civil Liberties (CNIL) and the National Agency for the Security of Information Systems (ANSSI). The company is also notifying affected customers via email about the potential data compromise.
Filing a Criminal Complaint
In addition to informing regulatory authorities, Free has lodged a criminal complaint against the unknown perpetrators. By pursuing legal action, the ISP aims to bring accountability and prevent similar incidents in the future.
What Customers Should Know
Customers should expect to receive official communication from Free in the coming days, detailing how they may have been impacted and recommending security measures they can take.
The Growing Cyber Threat Landscape for ISPs
Why Are ISPs Being Targeted?
Cyberattackers are increasingly targeting ISPs due to the wealth of data they handle, including user billing, SMS data, and personal information, which can be lucrative on the black market. Moreover, compromised ISP networks offer attackers a pathway to infiltrate multiple systems, potentially leading to larger, multi-stage cyber campaigns.
Other Notable ISP Attacks
France’s Free ISP is not alone in being targeted by cybercriminals:
- Salt Typhoon Attacks in the U.S.: This APT group has targeted U.S. ISP networks to gather billing information and personal addresses.
- Evasive Panda’s DNS Poisoning Attack: This group exploited software vendor update mechanisms by infiltrating ISPs, allowing them to distribute malware through routine software updates.
Implications for ISP Security
With ISPs increasingly in the crosshairs, these companies are under pressure to enhance security protocols. They are adopting advanced encryption, multi-factor authentication, and real-time threat detection systems to mitigate future risks.
How to Stay Protected as a Free Subscriber
Steps for Users to Protect Themselves
- Monitor Financial Statements: Although no bank card information was compromised, it is advisable to watch for any unusual activity on accounts.
- Avoid Phishing Scams: Be cautious of any suspicious emails or messages pretending to be from Free, especially ones asking for sensitive information.
- Enable Two-Factor Authentication (2FA): Many accounts offer 2FA, which can help secure personal information in case of attempted account access.
What Free Can Do for Future Security
To regain customer trust, Free may consider additional measures such as enhanced encryption, regular security audits, and establishing a clear incident response plan for any future breaches.
