Inloggningslog Event 4625 i mängder
Hej,
Upptäckte idag på min hemmaserver att jag har +37k felaktiga inloggningsförsök i loggern och att det konstant sker nya...:
Kom på det eftersom att mitt konto var "locked-out" från remote access så var tvungen att logga in lokalt. Det har varit så ett bra tag men jag har inte orkat fixa det förens ikväll.
I huvudsak är det login försök mot kontona Admin, Backup och IT:

The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.

IP 194.180.48.174 är inget jag känner till... det IPet står för 99,99% av alla felaktiga inloggningsförsök som görs.
Nu den senaste timmen har det även varit liknande försök ifrån andra ipadresser så som 77.245.107.189, 202.165.25.140, 89.248.192.27, 183.81.32.189, 45.227.254.151, 15.204.218.145, 65.109.108.183 mot konton som Administrator, USER, USER1, JOHN
Någon som försöker bruteforcea sig in i min server eller?
Det finns ingen data på servern. Jag har bara börjat installera "File Browser", Docker och Nextcloud men ingenting är klart eller up n running... så det finns verkligen inget värt att stjäla eller som jag är rädd att förlora.
Vad ska jag göra? Det är ju väldigt jobbigt att konstant bli locked-out också...
