    Used to be that ransomware only looked at hard drive C:, and then any other mapped drives like D:, E:, F: etc., but now a newly discovered strain called CryptoFortress was discovered yesterday by security researcher Kafeine that has stolen the look & feel of TorrentLocker but is a whole new malicious strain. It would be a bit much to call this a new generation, but it certainly is a powerful new feature.

    CryptoFortress includes the new and nasty feature of being able to encrypt files over network shares even if they are not mapped to a drive letter. Normally when ransomware encrypts your data it does so by retrieving a list of drive letters on a computer and then encrypting any data on them.......

    On a different thread of Tony's, he could have done with installing that Crypto Monitor! :biggrin:
    However, reading up on how Crypto Monitor works, I would think it has a good chance of trapping even that latest one.
    I have taken some notice of it and downloaded the free version, once I install it I can report on my impression of it at some later date.

    Nathan does say that CM does detect and trap CTB Locker.
    I actually joined 'Nathans' testing team for Crypto Monitor.
    I was testing it on the new Win10.
    We actually went through quite a few changes before arriving at the version you now see.
    Although we did work with the Pro version, I have opted to just install the free version now.
    It actually does what it says on the tin.

    Tony I am putting Crypto Prevent and Unchecky now on every computer I service and explaining how to update Crypto Prevent. I have to get that into my 6 step memo for success I leave everyone and tell them iof they do all those things faithfully, they will not get reinfected.
