Ransomware’s arms race: What banks have to do
Ransomware is on the rise, and it’s more destructive than ever.
On Friday, a hacker group that calls itself Shadow Kill Hackers infected the city of Johannesburg and held its data for ransom. The hackers demanded four bitcoins be paid by Monday at 5 p.m. local time, or they said they would upload the city’s data on the internet. The situation was still up in the air late Monday, with city officials saying they would not cooperate, according to news reports.
