Description
Brain Cipher ransomware surfaced in mid-2024, rapidly gaining notoriety after a high-impact attack on Indonesia’s National Data Center, which disrupted over 160 government services including immigration systems. The group operates with a double-extortion model, encrypting data using a LockBit 3.0-based payload (Salsa20/RSA hybrid) and threatening leaks via a Tor-hosted portal. Distinct behaviors include encrypting both file contents and filenames, and customizing encrypted file names with appended random extensions. Initial access methods include phishing and purchases from initial-access brokers. Ransom demands have ranged from tens of thousands up to $8 million USD, though victims have sometimes been offered decryption keys without payment. Victims span sectors such as government, healthcare, education, media, and manufacturing across Southeast Asia, Europe, and the Americas.
