SFR hit by new cyberattack, data of 3.6 million subscribers leaked

PatternExternal actor · Hacking · Confidentiality impact

The French telecommunications operator SFR was reportedly hit by a new cyberattack on November 24, 2024, with the hacker collective Near2tlg claiming to have compromised the personal data of 3.6 million subscribers. The stolen data, including names, addresses, and phone numbers, was initially offered for sale for 500 euros in cryptocurrency but was later published for free after SFR denied the new attack. The attack reportedly exploited a vulnerability in SIBO360, an internal management software used by SFR. SFR, however, attributed the incident to a previous leak from September 2024.

    CTIVD: AIVD en MIVD verwerken persoonsgegevens in bulkdata onrechtmatig

    The Dutch intelligence services, AIVD and MIVD, have unlawfully processed personal data in bulk datasets, according to a ruling by the Committee for the Supervision of the Intelligence and Security Services (CTIVD). The report, published on July 1, 2026, states that groups of employees had unauthorized access to personal data, and large quantities of data were stored for too long. The bulk datasets, sometimes containing millions of records, include names, phone numbers, location data, social media data, and communication content, sourced from government agencies, commercially available datasets, or stolen datasets offered by criminals. The CTIVD has issued thirteen recommendations to improve the situation.
