How to Restore Data After Ransomware

Restoring data after a ransomware attack typically means cleaning the computer of any malware, verifying that you have secure backups, and then restoring your clean data from these backups, all while avoiding paying the ransom.

 

How to Restore Data After Ransomware

 

When your files have been locked or encrypted by ransomware, the first step is to ensure the malware is completely removed from your system. This is usually done by booting into a safe mode or using a trusted bootable antivirus to scan and clean your system. Only after confirming that the system is clean should you attempt any data recovery.

If you have backups, which are copies of your data stored on separate media or cloud services, you should verify that these backups are safe and not infected. It’s important that your backups were created before the attack occurred. In cases where backups aren’t available or are compromised, you may need specialized data recovery tools and professional help.

When putting your data back, follow these steps:

  • Disconnect and isolate: Immediately disconnect the affected system from networks to prevent the spread of the ransomware to other devices.

  • Clean your system: Use a reputable antivirus or malware removal tool to thoroughly remove any threats remaining on your computer.

  • Verify your backups: Check that your backup files are intact and from before the attack. This means confirming that the data is not corrupted or influenced by any malware.

  • Restore data safely: Once your system is cleansed, begin restoring your data from the verified backup files to a secure, updated system.

  • Update security measures: After restoration, apply all necessary updates, change passwords, and implement stronger security policies to prevent future attacks.

  • Consider expert review: We recommend reaching out to a readiness-assessment firm like OCD Tech to review your security posture, ensuring your systems and backups are resilient against potential future threats.

If no backups exist, it is crucial to recognize that restoring data successfully becomes far more complicated, and paying a ransom does not guarantee data return. Instead, you may need to use advanced recovery techniques or consult with a cybersecurity professional for forensic recovery options. Always ensure to report such attacks to law enforcement as part of a coordinated response to cybercrime.

Remember that prevention is key; regularly backing up your data and keeping your security software up to date are your best defenses against ransomware attacks.
