The International Criminal Court (ICC) reported it experienced a cyber incident affecting its information systems.

“At the end of last week, the International Criminal Court’s services detected anomalous activity affecting its information systems. Immediate measures were adopted to respond to this cybersecurity incident and to mitigate its impact,” the organization wrote.

The ICC, headquartered in The Hague, Netherlands, is the first and only permanent international court with jurisdiction to prosecute individuals for the international crimes of genocide, crimes against humanity, war crimes and the crime of aggression.

Established in 2002, the organization is currently investigating crimes against humanity in Ukraine. In March 2023, the court issued arrest warrants for Russia’s President Vladimir Putin and Commissioner for Children’s Rights in the Office of the President of the Russian Federation Maria Lvova-Belova, both accused of the war crime of unlawful deportation of Ukrainian children from occupied areas of Ukraine to Russia.

The ICC didn’t reveal the nature of the incident or whether any data had been stolen.

The court said it “continues to analyze and mitigate the impact of the incident” adding that “priority is being given to ensuring that the core work of the Court continues”.
