Sophos is just re-hashing the DM report. I hate blog spam.

Ok, we changed to that from http://nakedsecurity.sophos.com/2019/03/22/sacked-it-guy-ann..., in keeping with the guidelines' call for original sources (https://news.ycombinator.com/newsguidelines.html).

AWS have services to back up your data. Anything that a human or automation can touch can be obliterated instantly. This includes your live, staging and disaster recovery sites.

Important data must be backed up where humans and automation can't remove it. A vaulting policy / data retention policy is also useful.

does aws actually have that. everythings an API on aws right? so couldnt someone just send the delete backup command to whatever backup service aws has?

You send your backups to another AWS account, that has distinct access credentials another responsible party holds (separation of duties), and policies that inhibit the backup source account from deleting or modifying the backups in the target account.

You should practice restores. You should be able to stand your infra back up from anywhere with an Internet connection.

Data protection account is a good idea, but if your main IT person is malicious before such an account gets implemented it won’t matter.

Trust but verify. Having a third party audit and provide findings (if you’re not technically capable as an owner) is cheaper than going out of business.

No 2FA? Totally Incompetent.

He just used his account ¯\_(ツ)\_/¯
