Verdict:	Malicious activity
Threats:	Play aka PlayCrypt ransomware group has been successfully targeting corporations, municipal entities, and infrastruction all over the world for about three years. It infiltrates networks via software vulnerabilities, phishing links and compromised websites. The ransomware abuses Windows system services to evade detection and maintain persistence. Play encrypts user files and steals sensitive data while demanding a ransom. Ransomware is a type of malicious software that locks users out of their system or data using different methods to force them to pay a ransom. Most often, such programs encrypt files on an infected machine and demand a fee to be paid in exchange for the decryption key. Additionally, such programs can be used to steal sensitive information from the compromised computer and even conduct DDoS attacks against affected organizations to pressure them into paying.
