WannaCry Strikes Big Player’s Computers Across the World
China is one of the most affected nations in Asia with thousands of computers infected by WannaCry.
Renault, a French automobile company, has paused the operations in several of its facilities, while German Railway company Deutsche Bahn have malfunctioned ticket machines and screens after the virus attack. The virus didn’t even spare Interior Ministry of Russia. Dharmais Cancer Hospital in Jakarta, Indonesia’s largest facility, access to patients’ medical records was denied after the attack.
The hacked computers are displaying a note asking for a ransom of US$300 (S$420), threatening that their encrypted data would otherwise be deleted.

WannaCry is a ransomware being sent to the victim’s PC as an infected file via e-mail or URL. Once you open it, the infected code would enter your system. Later, it will lock all the files on your computer with an encryption key. Within few minutes, your files are locked. A message appears on your screen which demands a ransom in a bitcoins to unlock your data. If you don’t pay, your file will be deleted.
