Threat: Trojan-Dropper.Win32.Daws.etlm  
Vulnerability: Remote Unauthenticated System Reboot  
Description: Daws.etlm drops an executable named "MSWDM.EXE" under Windows dir and listens on UDP port 139. Unauthenticated third-party attackers can send a single uppercase char "D" datagram packet to the infected machine causing it to reboot. Basic testing using other upper/lower case chars from A-Z or numbers 0-9 did not reveal anything else of interest.  
Type: PE32

Vuln ID: MVID-2021-0111
