Hackers don't just want your data anymore. They want your backups. ๐จ
Ransomware operators have changed their strategy. They know that if they just encrypt your live database, you can just restore it from yesterday's backup and ignore them. So, their new primary target? Your backup repositories. If they delete or encrypt your backups, you lose your only leverage. You either pay the ransom, or you lose your company.
The Fix: WORM Architecture (Write Once, Read Many)
The only real defense against this is configuring immutable backups. This means once your backup data is written to a drive, it is cryptographically locked. Nobodyโnot a rogue script, not a hacker, and not even you (the sysadmin)โcan delete or modify it until a specific timer (like 14 days) runs out.
How to build it without going broke:
Most companies just dump their backups into AWS S3, but when disaster strikes and you need to download terabytes of data, AWS hits you with insane "egress fees."
A much smarter, cost-effective way is to host your own backup vault. By provisioning an isolated, high-performance Dedicated Server, you get unlimited traffic and a flat monthly rate.
We recently built an incredible tech stack for this using two open-source powerhouses:
MinIO: A self-hosted S3 alternative that we use to enforce "Compliance Mode" Object Locking.
Restic: A tool that encrypts all your data locally (AES-256) and deduplicates it before sending it to the vault.
If you are a sysadmin, dev, or just a tech enthusiast looking to secure your infrastructure, you can copy our exact bash scripts, cron jobs, and Docker configurations.
