On June 20, 2024, the Indonesian data center experienced a severe ransomware attack by the group Brain Cipher, impacting approximately 210 critical government services, including customs and immigration. This led to significant delays for travelers at airports.

Initially demanding an $8-million ransom, Brain Cipher later released the decryptor for free. Group-IB's High-Tech Crime Investigation team has provided insights into the group's previous activities and tactics, revealing their use of ransom notes and data leak threats as extortion methods. The Brain Cipher group has been active since at least April 2024 and shows connections to other ransomware entities such as EstateRansomware and SenSayQ.
