    BitLocker and DMA and Memory Resilience attacks?


    I an running BitLocker with fully encrypted OS drive with TPM only authentication.

    I have Sleep mode disabled with a setting: Never

    When not using my laptop, I power OFF my system completely.

    My question is, am I still vulnerable to DMA attacks if I shutdown my laptop completely when I am finished using my laptop?

    I read that DMA attacks only occur when the systems are not fully powered down , meaning there are just only Locked with the Windows Logon screen, Sleep mode, or just reboot.

    :)

    BitLocker with TPM mode protection only?


    I have a laptop which is a Dell E6440 and was just wondering if it vulnerable to these DMA attacks through Thunderbolt and Firewire methods.

    Reason asking, is because I have BitLocker full disk encryption turned ON with TPM-Only protection (meaning no PIN).
    Would this be fine or how can I tell if my laptop is vulnerable to DMA or Memory attacks?

    Overall, is it OK to use BitLocker with TPM-only protection or do I need a PIN as well?

    Dma ?

    On my sys. (sys. listed), how do I enable or disable DMA on my Sata drives? I have a Sumsung SH-S203b Dvd recorder (sata) and in the Nero info tool I get a warning that DMA is disabled on this drive. On my old sys. (P4C800-E Deluxe) the Intel raid driver software provided control of dma. On the P5K Deluxe where do I find the drive settings (DMA or PIO) and how would I change them?

    Thank You.

    Appear to have been attacked with Bitlocker


    Bitlocker is part of Windows OS and should not be attacking your computer, is it possible that this is a ransomware attack that mimics Bitlocker? If so you need to find help of a forum that deals with malware. If this is actually Bitlocker that is malfunctioning you may be hooped and have to reformat.
