  Ransomware attack are successful mostly against MS Active Directory and Ourlook based setups.

    That’s hilarious. Big corporation apparently can’t afford basic cybersecurity. Always pinching pennies.

    Anyway, any big organization should encrypt their core systems to prevent ransomware attacks. Individuals should too. It’s just good practice.

      Encryption alone won’t prevent ransomware to encrypt it again. The original files need to be readable after all, so they are either unencrypted at boot or appear unencrypted to the (infected) client by machine/session key management. Nevertheless, adding an addittional, "“hostile” encryption layer will make them unreadable. The reasonable thing would be not to use a monocultural, standard setup that is known to be vulnerable to that kind of attack and first of all to get rid of fucking Outlook which has always been a dumpster fire.

        Oh man, I always thought if your drive was already encrypted that a hostile actor couldn’t encrypt it for ransomware. I don’t know where I read that but it was a long time ago and I guess someone lied to me, but it’s whatever.

        So what’s the vulnerability that would be exploited, something about using the swap space to get into the encrypted drive? Or does the attack apply to the outside of the container? I’m curious cause I’m working on hardening my own system currently and I want to make sure I’m not leaving any gaps in my blind spots
