The French telecommunications company Orange, one of the largest telecom operators in the world, reports the discovery of a compromised system within its network.
On July 25, 2025, the compromised system was detected and isolated from the rest of the company’s network by specialists from the Orange Cyberdefense division, which focuses on cybersecurity issues.
It is reported that this caused disruptions primarily affecting French Orange customers. The issues are expected to be resolved today, July 30.
“On Friday, July 25, Orange Group detected a cyberattack on one of its information systems. Upon receiving the alert, with the support of Orange Cyberdefense, our teams were fully mobilized to isolate potentially affected services and minimize the consequences,” the company said in an official statement. “However, these actions to isolate the systems resulted in disruptions to some services and management platforms for our business clients, as well as affecting a number of consumer services, mainly in France.”
The company has already informed the relevant authorities about the cyberattack. It is also emphasized that, at present, the investigative team has not found any evidence that any data may have been stolen during the breach.
Orange does not associate this incident with any specific hacker group. However, it clearly resembles a series of large-scale breaches affecting telecommunications companies worldwide, including AT&T, Verizon, Lumen, Charter Communications, Consolidated Communications, and Windstream (1, 2, 3). The FBI and CISA attribute these attacks to the Chinese cyber-espionage group Salt Typhoon.
