What it detects

This rule detects the creation of a Run key registry value pointing to the WannaCry payload tasksche.exe, establishing persistence at user logon. The malware writes this value under the CurrentVersion Run key to survive reboots. Presence of a tasksche.exe reference in an autostart location is a high-confidence indicator of WannaCry infection.
