    How to prevent disk encryption (block ransomware)?



    The Sunday NY Times Week in Review (Jan 4, 2015) had an article about someone’s mother having to pay Bitcoin ransom in a ransom malware encryption attack.

    At home, what should I do to prevent a ransom encryption attack, in addition to Avast AV (on my home Win 7 Pro 64-bit and my home XP Pro SP3) or Windows Defender (on my home Win 8.1 Pro 64-bit)?

    One of the readers asked whether there’s an app that prevents encryption of a disk or partition unless there’s confirmation at the keyboard (like a UAC prompt). Sounds like a good idea - is there any way for me to add this?

    Thanks.


    (PS and FYI – I have Windows Defender on my 8.1 because Avast 2015 uses up the entire capacity for hardware-assisted virtualization, which I intend to play with later. Similarly, on my 7, I still have Avast 2015 but I have turned off its “Enable hardware-assisted virtualization” for the same reason. Finally, on my XP, I have Avast 2015 and have left ON its “Enable hardware-assisted virtualization” because, on XP, there’s no interference with HAV. But probably not relevant to my question.)

    The best defense is using your head when surfing. You may also be interested in this:

    I would recommend HitmanPro wich will automatically before the Cryptolocker can do anything, prevent it from even packing up and getting to ecrypt your HDD/SDD.

    Also an up-to-date and OS without any component store issues- I got stung badly on my old PC when I couldn't repair corruption and there were holes in my defences and I had a few heavy problems. The greatest threat is people still opening suspicious email attachments and getting attacked that way.

    The best protection against any kind of infection, especially ransomware is to back your data up on a regular basis. This way, if your pc is really infected, you can simply wipe the system drive plus drives that are encrypted and restore your images of the system and your data partitions. Just make sure you use external drives for your backups and disconnect them after the backup process so they are not encrypted too when/ if a ransomware infects your pc.

    Altac and others - thanks for your wise suggestions. Question:

    If I back up data using Cubby or Sugarsync and I'm hit with a ransomware encryption, is it possible my backups will also be infected? I ask because MAYBE the Cubby or SugarSync backup ALSO appears as a "drive" on my PC.

    Thoughts?

    Both pieces of software you mentioned are unknown to me. But to be on the save side I recommend you using a imaging solution like Paragon Backup, EasUs Backup, Acronis True Image... to make images of all the partitions which contain valuable data. Plus I would frequently make images of your Windows drive so in case you actually get hit by a malicious program you can easily restore your Windows system. I'd definitely use an external hd for this. Synching important files as a backup is fine but in case you get hit by a reallly nasty virus you want to have images on an external hd that is not constantly connected to the pc and thus not infected.

    ... and keep the backup drive DISCONNECTED at all times, except when either making a new backup of a still clean machine or restoring data to a newly cleaned and rebuilt system. If you leave the backup connected or reconnect it to a infected machine you can loose its data as easily as that on the main drive.

    Yep, as inconvenient as it might seem, backing up your data is the only real protection. AV software, firewalls, malware cleaner... are all ok but without an appropriate backup strategy your data will never be save.

    This gets into ethics, but the more people pay to 'save' their stuff from criminals, the more criminals target others to get them to do the same. You pretty much condemn another to share your fate.
