tl;dr: A hacker breached Romania's National Agency for Cadastre and Real Estate Advertising (ANCPI) using valid credentials, then wiped the country's land registry database and backups after a failed extortion attempt, halting real-estate transactions for a week. The attacker, identified as ByteToBreach (allegedly Algerian national Zakaria Mahdjoub), also leaked stolen employee credentials and internal documents on a hacking forum. ANCPI is rebuilding its network from scratch and appears to have offline backups, joining Poland, Slovakia, Greece, and others whose land registries have been hit in recent years.
