Verdict: Malicious activity
Threats:

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.
