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. WannaCry is a famous Ransomware that utilizes the EternalBlue exploit. This malware is known for infecting at least 200,000 computers worldwide and it continues to be an active and dangerous threat. WannaCry ist eine bekannte Ransomware, die die EternalBlue-Schwachstelle nutzt. Diese Malware ist dafür bekannt, dass sie mindestens 200.000 Computer weltweit infiziert hat, und sie ist weiterhin eine aktive und gefährliche Bedrohung. Malware Trends Tracker >>>
