The National Cyber and Crypto Agency (BSSN) of the Republic of Indonesia conducted an investigation and found that this attack was caused by the “Brain Cipher Ransomware”, a latest development of Lockbit 3.0. The attack occurred because the Windows Defender security feature was reactivated on June 17, 2024, allowing malicious activities to occur. BSSN also found that the attack was carried out using phishing techniques, where the attackers sent emails containing malicious files to PDNS staff.
