Would a Crypto-Trojan also encrypt a tib file on external drive?
There is a lot of rumor in the press about crypto trojan programs coming hidden in mail attachments which encrypt any data-file on the PC even on network attached cloud drives as reported this week.
What does that mean to my daily USB-backup tib files on external HDDS wich are permanently connected to the PC?
How can I prevent fraude- encryption of backup files- except by switching the HDD.s off after backup- or disconnecting. which would be pretty unmanagable?
Any good advice?
