Bouygues Telecom prévient actuellement pas moins de 6,4 millions de clients d’un accès non autorisé à certaines de leurs données personnelles… mais aussi bancaires. Attention donc aux risques de phishing et de prélèvements sur vos comptes.

Après une fin d’année 2024 et un début 2025 sur les chapeaux de roues pour les fuites de données, la situation s’était un peu calmée, mais ce fut de courte durée. L’été est chargé, avec des incidents cyber chez Louis Vuitton, France Travail, Allianz Life, Pandora et maintenant Bouygues Telecom.

On y retrouve des informations personnelles telles que les coordonnées, des données contractuelles liées à votre abonnement, des données d'état civil ou celles de l'entreprise si vous êtes un professionnel, ainsi que les IBAN sur la partie bancaire. Toutefois, « les numéros de cartes bancaires et les mots de passe de vos comptes Bouygues Telecom ne sont pas impactés ».

En octobre, Free aussi avait été victime d’une fuite de données personnelles, avec des IBAN. Quelques semaines auparavant, c’était RED by SFR, là aussi avec des données bancaires.

Les risques liés à la fuite d’IBAN
L’IBAN (International Bank Account Number) est l’identifiant international de votre compte bancaire, rattaché à une institution financière dans un pays (il commence par FR pour France, DE pour Allemagne…).

Selon la Banque de France, « communiquer son RIB n’est pas risqué en soi ». Mais « comme pour tout document contenant des informations personnelles, il convient de bien identifier la personne à laquelle vous communiquez un RIB. Un escroc pourrait utiliser ces informations de manière malveillante (ex : usurpation d’identité) », ajoute l'institution.

De son côté, Bouygues Telecom assure qu’une « personne qui détient un numéro IBAN ne pourrait pas émettre de virement sans votre accord ». À juste titre, l’opérateur prend soin d’ajouter que, concernant les prélèvements, c’est plus compliqué : « il est normalement nécessaire que le titulaire du compte signe un mandat SEPA, mais on ne peut pas exclure qu'un fraudeur parvienne à réaliser une telle opération en se faisant passer pour vous ».

En effet, lorsque la signature consiste en un SMS ou un email, une usurpation d’identité est facile à mettre en place.
Bouygues Telecom conseille donc à ses clients de vérifier les prélèvements et d'appeler la banque en cas de doute : « Sachez que la règlementation bancaire prévoit que vous puissiez vous opposer pendant 13 mois à tous les prélèvements effectués sans votre accord sur votre compte bancaire ».

Les cyberattaques sont « très fréquentes et n'épargnent » personne
L’opérateur ne donne pas de détails sur la cyberattaque. Il précise simplement avoir bloqué l'accès, renforcé la surveillance « et mis en œuvre des mesures complémentaires nécessaires ». L’entreprise rappelle aussi que les cyberattaques sont « très fréquentes et n'épargnent aucune entreprise »… un argument repris récemment par Pandora, dans une communication pour le moins surprenante.

Comme l’y oblige la loi, la CNIL a été informée de la situation. De plus, une plainte a été déposée auprès des autorités judiciaires.

Le risque en pareille situation, sans parler des prélèvements sur votre compte, est d’être la cible de phishing. Des pirates peuvent utiliser les données récoltées pour se faire passer pour Bouygues Telecom ou votre banque, afin de récupérer des données supplémentaires.

Luxembourg probes reported attack on Huawei tech that caused nationwide telecoms outage | The Record from Recorded Future News https://therecord.media/luxembourg-telecom-outage-reported-cyberattack-huawei-tech

therecord.media (01.08.2025) - Authorities in Luxembourg said a nationwide telecommunications outage in July was caused by a deliberately disruptive cyberattack. Huawei networking products were reportedly the target.
Luxembourg’s government announced on Thursday it was formally investigating a nationwide telecommunications outage caused last week by a cyberattack reportedly targeting Huawei equipment inside its national telecoms infrastructure.

The outage on July 23 left the country’s 4G and 5G mobile networks unavailable for more than three hours. Officials are concerned that large parts of the population were unable to call the emergency services as the fallback 2G system became overloaded. Internet access and electronic banking services were also inaccessible.

According to government statements issued to the country’s parliament, the attack was intentionally disruptive rather than an attempt to compromise the telecoms network that accidentally led to a system failure.

Officials said the attackers exploited a vulnerability in a “standardised software component” used by POST Luxembourg, the state-owned enterprise that operates most of the country’s telecommunications infrastructure. The government’s national alert system, which officials had intended to use to warn the population about the incident, failed to reach many people because it also depends on POST’s mobile network.

POST’s director-general described the attack itself as “exceptionally advanced and sophisticated,” but stressed it did not compromise or access internal systems and data. POST itself and the national CSIRT are currently forensically investigating the cause of the outage.

Although the government’s statements avoid naming the affected supplier, Luxembourg magazine Paperjam reported the attack targeted software used in Huawei routers. Paperjam added that the country’s critical infrastructure regulator is currently asking any organisations using Huawei enterprise routers to contact the CSIRT.

Remote denial-of-service vulnerabilities have previously been identified in the VRP network operating system used in Huawei’s enterprise networking products, although none have recently been publicly identified. Huawei’s press office did not respond to a request for comment.

The Luxembourg government convened a special crisis cell within the High Commission for National Protection (HCPN) to handle the response to the incident and to investigate its causes and impacts, alongside the CSIRT and public prosecutor.

The CSIRT’s full forensic investigation is intended to confirm how the attack happened, while the public prosecutor will assess whether a crime has taken place and if a perpetrator can be identified and prosecuted.

The incident has also accelerated Luxembourg’s national resilience review, a process already underway before the attack. Authorities, concerned that a single point of failure had such a dramatic disruptive effect, are now reassessing the robustness of critical infrastructure, including fallback procedures for telecom and emergency services.

Luxembourg is also exploring regulatory changes to allow mobile phones to automatically switch to other operators’ networks during telecom outages, a practice already used in countries like the United Kingdom, Germany and the United States for emergency calls.

Russian hackers were inside Ukrainian telecoms giant Kyivstar's system from at least May last year in a cyberattack that should serve as a "big warning" to the West, Ukraine's cyber spy chief told Reuters.

The hack, one of the most dramatic since Russia's full-scale invasion nearly two years ago, knocked out services provided by Ukraine's biggest telecoms operator for some 24 million users for days from Dec. 12.
