Adobe issued a security update April 7 that addresses what the software maker calls 'critical vulnerabilities' in its Flash Player that could allow intruders to take control of a victims computer.
The vulnerability affects Flash running on Windows, Mac, Linux, and Chrome OS operating systems. Trend Micro, one of the companies involved in spotting the issue, said that the vulnerability was found to be spreading what is been called the 'Locky ransomware.' Ransomware is a type of malware (malicious software) that essentially holds a victims computer hostage. The attacker typically blocks off access to the system until a sum of money is paid over the Internet.
