GlobeImposter

aka: Fake Globe
URLhaus      

GlobeImposter is a ransomware application which is mainly distributed via "blank slate" spam (the spam has no message content and an attached ZIP file), exploits, malicious advertising, fake updates, and repacked installers. GlobeImposter mimics the Globe ransomware family.
This malware may prevent execution of Anti-Virus solutions and other OS related security features and may prevent system restoration.
