[ale] Linux Ransom-ware

[Scott Plante]

The article says it goes after backup files too. It seems what you need is either a backup drive or media you manually connect to do backups, or a separate backup server that only accepts new backups and doesn't give the client write access to old backups. I think it might be fairly easy to script something like this, but is anyone aware of an existing backup server software that does this kind of thing? Most of the backup software I've seen assumes you have read/write access to a "backup drive" whether that's a USB, NFS, or other network accessible mount, or of course a tape or dvd that someone manually changes. For all the advantages of removable media, you always have the problem of human error or laziness fouling up your backup regime, so automated is good. 


For a backup server, it would of course be of some limited space. You wouldn't want the push process to be able to just keep pushing junk until your good backups are pushed off. Just a thought that popped into my head in the vein of maybe a push-only backup server is more complicated than I first thought. Seems like some of the issues people have worked out for log servers that accept log messages but are extra hard for hackers to mess with.

Good news; we're all now reminded to back up our files and sites. :)
