iBasis is a US-based telecommunications company that provides services in the areas of speech processing, mobile data, and Internet-based infrastructures.

More than 1,000 mobile, landline and Internet service providers have partially or completely outsourced their international voice data traffic to the US company.

In addition to Swisscom, Sunrise and Salt, iBasis’ clients also include several global providers such as Skype, Telecom Italia, Vodafone, Verizon and China Mobile.

Hubacher said Swisscom does not have a direct business relationship with iBasis, apart from roaming connections through operators that can use iBasis as a data carrier.

The Swiss provider is in close contact with its partners to verify whether or not Swisscom customer data will be affected.

Switzerland’s second largest telecom operator also said it would work with iBasis in areas such as international calls. Rolf Siebold, a spokesman for Sunrise, told SDA that it was still being investigated whether customer data was affected. Salt has not yet responded to any inquiries.


The cyber attack has temporarily released information about the communications of these providers’ clients on the dark web, writes “Le Temps”.
