Ilham Negara, who was taking his girlfriend's mother for surgery at Dharmais Cancer Hospital in West Jakarta on Saturday morning, was perplexed when he discovered he could not get a queue number for admission.
Suffering from stage 2 cervical cancer, his girlfriend's mother was scheduled for surgery on Monday and was advised to stay at the hospital for two days prior to the surgery.
When Ilham proceeded to take the queue number he was greeted by an unusual message on the computer's display saying "Ooops, your files have been encrypted!".
The red background display was equipped with a digital timer to inform the reader how many hours were left before the files were deleted by the hacker, as well as a ransom statement, which stated they must send US$300 (S$421) worth of bitcoin, or around Rp 4 million (S$421) to a site address to recover the encrypted files.
