At least two of Indonesia’s major hospitals have been struck in the “ransomware” cyber attack that infected computers globally. Dharmais Hospital and Harapan Kita Hospital in Jakarta are affected by the ransomware, said Semuel Pangerapan, a director general at Indonesia’s Communication and Information Ministry. Cyber extortionists tricked victims into opening malicious malware attachments to spam emails that appeared to contain invoices, job offers, security warnings and other legitimate files. The ransomware encrypted data on the computers, demanding payments of $300 to $600 to restore access. The attack, which leverages hacking tools believed to have been developed by the US National Security Agency, has infected tens of thousands of computers in nearly 100 countries.
