Dozens of Canadian firms have paid money for a year to hackers to regain control of their data being drawn off.
A study in Canada and three other countries by Osterman Research, a company based in Black Diamond, in Washington, concluded that 44 of the 125 Canadian companies anonymously surveyed had been victims of extortion computer during the previous 12 months.
Hackers engaged in these activities prevent computer users to access data they deserve and require payment in return for a recovery.
Of the 44 Canadian victims, 75% have paid ransoms amounts between $ 1,000 and $ 50,000. Eleven firms had to stop their activities for a while to fix it.
The study found that one of the sectors most frequently targeted by hackers activities is health care because access to computer data on patients is often essential to medical treatments are offered.
The study of Osterman Research was published by Malwarebytes, a California company dedicated to the protection against threats on the Internet.
