Ransomwareis one of the most dangerous cyber threats today.
Attackers encrypt your files and demand payment to restore access.
In many cases, even if the victim pays the ransom, the attackers still wont release the files.
If your backups are unprotected, you could lose everything.
This guide explains how to protect your backups from ransomware.
Traditional ransomware only encrypts current files, and it’s possible for you to restore them using backups.
Modern ransomware proactively searches for and encrypts/deletes backups to ensure you cannot recover files.
Here are the 4 common methods that ransomware attacks your backups.
Attack backup software vulnerabilities
Many systems have security vulnerabilities that ransomware exploits.
Unpatched backup software, default passwords or weak credentials, and excessive privileges may cause the backups being attacked.
Lurk in your box and attack the backups
Advanced ransomware does not encrypt immediately, but infects backups first.
After entering the system, it remains silent (days or even weeks).
During this period, it infects all backups.
Eventually triggers encryption, cause all backups unrecoverable.
Ransomware also target cloud backups
Cloud backups(such as Google Drive, Onedrive, etc.)
are not completely secure.
Ransomware can use leaked cloud credentials to delete backups, disable version control, and encrypt synchronized cloud backups.
They steal data first including sensitive information in backups, and encrypt backups.
Then, threaten to release data.
Even if you recovers the files, you may still be forced to pay the ransom.
6 Key Strategies to Protect Backups from Ransomware
How to prevent your backups from ransomware attacks?

Step 4: ClickOptionsand go to theBackup Optionspart.
Click thePasswordtab and enable password protections.

Isolation is a key requirement at protecting nackups from ransomware.
This could well be done provided internally by separate backup networks and separate admin.
Secure Backup Access
To prevent your backups from ransomware attacks, you should secure bakup access.
This post shares several no-cost protections to help you take a proactive approach to response how to prevent ransomware.
Determine which systems are affected and isolate them immediately.
Isolate infected devices from the local online grid to prevent further spread.
