A hacker group claims to have gained access to data from thousands of SIM cards through a complex cyberattack targeting Schepisi Communications, a renowned Australian-based telecommunications company. On its website, this company claims to be associated with telecommunications giant Telstra, providing phone numbers and cloud storage services.
The claims of these hackers appear to be true, as the company’s official platform has been out of service for days. In addition, internal sources mention that company executives have already received a ransom note in which hackers claim to have accessed all kinds of confidential information, including SIM cards, payment details and contracts, among other records.
In this regard, Telstra has already confirmed a cybersecurity incident affecting one of its distributors, without explicitly naming Schepisi Communications: “We have contacted the affected company, so we are aware of access to certain confidential information,” a Telstra spokesperson said. The representative of Tesltra added that the company has strict guidelines established for access to the personal data of its customers for the purposes permitted by law, in addition concluded its message ensuring that the affected systems are not connected to Telstra’s networks.
Moreover, some of the documents exposed on dark web as an extortion method show what appear to be names and phone numbers of some affected customers. The leak also includes information from Schepisi’s business customers, including companies such as Nestlé, some radio stations and financial services companies based in Australia.
Schepisi’s official platforms show that Schepisi offers access and support to Telstra’s services, working primarily with business customers. These services include advice on migrating documents from physical servers to cloud storage units, as well as complementary services.
