The Guardian says a late December 2022 cyber incident that caused the British newspaper to shutter its offices for weeks was caused by ransomware and informed staff Wednesday that hackers have accessed their data.
An email sent to its staff from Guardian Media Group CEO Anna Bateson and Editor-in-Chief Katharine Viner said the attack was likely triggered by a phishing email.
The newspaper did not provide details of the exposed data, although it clarified that no personal data of its readers or staff in its U.S. or Australian offices has been affected.
Their email also said the organization expects to restore some of the affected networks within two weeks. The Guardian notified the U.K. Information Commissioners’ Office and the police of the data breach and that the organization is working with security experts to understand the extent of the damage.
The newspaper has meanwhile asked its employee to continue to work from home until February as it restores the impacted systems.
