[ALERT] ADVISORY ON HELLO (WICKRME) RANSOMWARE
BACKGROUND
A brand new ransomware variant called .hello ransomware or WickrMe Ransomware uses a Microsoft SharePoint 2019 vulnerability (CVE-2019-0604) to enter the victims’ network. From there, the threat actor leverages Cobalt Strike to pivot to the domain controller and launch ransomware attacks.
.hello (WickrMe) ransomware encrypts files and appends the ".hello" extension. For example, it renames a file named "1.jpg" to "1.jpg.hello", "2.jpg" to "2.jpg.hello", etc.
