    SFR data breach controversy

    Issue disclosure

    SFR confirmed a data breach exposing personal information of some fibre customers, detected by its security teams on July 2, involving an internal tool used to manage and analyse fibre connections. SFR said it disabled the account used to access the tool, blocked and monitored the IP addresses involved, notified the CNIL and filed a complaint with the public prosecutor. Cyberattaque.org reported that a database containing around 2.1 million records was accessed, a figure SFR has not confirmed.
