Optus disputes that the cyberattack hack was not sophisticated

The cyber attacker in the 2022 Optus data breach had “a high degree of knowledge” of its confidential systems, the telecoms provider has claimed, as it seeks to refute the communications regulator’s accusations that the hack was unsophisticated.

Optus is being taken to federal court by the communications regulator, alleging it failed to protect customers’ confidential information before it was hit by a cyber attack at 8:17 a.m. on September 17, 2022. The attack lasted until approximately 3:45 a.m. on September 20.
