Trusseldatabase Malware Mimikatz

Mimikatz

Med GoldSparrow i Malware
Oversæt til:

Mimikatz eller Hacktool. Mimikatz er ikke klassificeret som et højrisikoværktøj, selvom det kan give en hacker adgang til en maskine ved at ødelægge bestemte muligheder i et Windows-operativsystem. Når en computer angribes af Mimikatz, kan dens controllere indsprøjte DLL'er i tilfældige processer, eksportere sikkerhedscertifikater, gendanne almindelig tekstadgangskoder fra Windows, deaktivere visse login og sikkerhedstjenester, slette nogle privilegier og unddrage sig et par gruppepolitiske indstillinger.

Hvis du har mistanke om, at Mimikatz kan have inficeret din computer, er der en nem måde at kontrollere den på: Brug en dedikeret scanner, fordi den kan registrere og fjerne Mimikatz. Men hvis du ikke er inficeret af det og ønsker at træffe foranstaltninger for at undgå infektioner, er der nogle strategier, du kan implementere, såsom at kontrollere kilden og pålideligheden af e-mails fra ukendt afsender, vær forsigtig, når du deler filer, del ikke med meget information om instant messengers, som kan forhindre utallige problemer, herunder blevet inficeret af mere alvorlige trusler.
