Lethal Lock Ransomware vil kryptere dine filer
Under vores analyse af nye malware-prøver stødte vi på en ransomware-variant kendt som Lethal Lock. Denne ransomware krypterer filer og tilføjer dens udvidelse (".LethalLock") til deres filnavne. Derudover genererer Lethal Lock en løsesumseddel ("SOLUTION_NOTE.txt") og ændrer offerets skrivebordsbaggrund.
For eksempel omdøbes filer krypteret af Lethal Lock som følger: "1.jpg" bliver til "1.jpg.LethalLock", "2.png" bliver til "2.png.LethalLock" og så videre. Løsesedlen starter med at anerkende brud på serversikkerheden af "LETHAL LOCK", en cyberentitet. Den beskriver krypteringsprocessen som yderst indviklet og advarer om, at det er næsten umuligt at gendanne filer uden dekrypteringsnøglen. Det truer med permanent datatab og øjeblikkelig handling, hvis løsesummen ikke betales inden for 72 timer.
Instruktioner til at nå kundesupport via Telegram (@lethallock) og overføre 25 bitcoins for at få dekrypteringsnøglen er inkluderet.

Hvordan kan du beskytte dine data mod Ransomware-angreb?
Beskyttelse af dine data mod ransomware-angreb kræver en flerlags tilgang til sikkerhed. Her er flere strategier, du kan implementere:
Sikkerhedskopier dine data regelmæssigt: Sørg for, at du har regelmæssige sikkerhedskopier af dine vigtige filer gemt på en sikker placering, der ikke er direkte tilgængelig fra dit primære netværk eller system. På denne måde, hvis du bliver offer for et ransomware-angreb, kan du gendanne dine filer fra backup uden at betale løsesummen.
Hold din software opdateret: Sørg for, at al software på dine systemer, inklusive operativsystemer, antivirusprogrammer og applikationer, er opdateret med de seneste sikkerhedsrettelser. Sårbarheder i forældet software kan udnyttes af ransomware-angribere.
Brug antivirus- og anti-malware-software: Installer velrenommeret antivirus- og anti-malware-software på alle dine enheder, og hold dem opdateret. Disse programmer kan hjælpe med at opdage og blokere ransomware-trusler, før de kan forårsage skade.
Aktiver e-mailfiltrering: Implementer e-mailfiltreringsløsninger for at blokere mistænkelige e-mails og forhindre dem i at nå din indbakke. Dette kan hjælpe med at reducere risikoen for at blive ofre for phishing-angreb, der distribuerer ransomware.
