Publicerad 2022-08-26 15:17 CERT-SE:s veckobrev v.34En grekisk leverantör av naturgas, ett franskt sjukhus och en leverantör till flygbolag har den senaste tiden utsatts för utpressningsvirus. Ytterligare organisationer berättar om både försök till och genomförda angrepp och ett felaktigt meddelande om "Luftangrepp, fara" har gått ut i Blekinge. Dessutom blir det som vanligt ett antal fördjupningar och mer tekniska analyser. Trevlig helg önskar CERT-SE!
