A ransomware attack can be one of the most damaging cybersecurity incidents faced by an individual or organization. Ransomware can encrypt documents, databases, accounting data, images, virtual machines, shared folders, network drives and backups, leaving users unable to access critical information.

However, seeing encrypted files does not automatically mean the data is permanently lost.

Depending on the ransomware variant, backup architecture, cloud storage configuration and condition of the affected systems, recovery may be possible through:

• Clean offline or immutable backups
• Cloud file version history
• Microsoft OneDrive or SharePoint recovery
• Vendor or security-researcher decryption tools
• Windows Volume Shadow Copies, when still intact
• Application-level backups
• Virtual-machine snapshots or backups
• NAS snapshots
• File recovery techniques in limited scenarios
• Professional ransomware incident-response and forensic recovery services

The most important rule is:

Do not immediately format, reinstall, delete encrypted files or pay the ransom. Preserve the affected environment until you understand what happened and what recovery options are available.

CISA recommends preserving relevant evidence where practical and restoring clean systems and data from offline backups while taking precautions against reinfection.

1. What Happens During a Ransomware Attack?

Ransomware is malicious software designed to deny access to systems or data, commonly by encrypting files.

A typical ransomware incident may involve several stages:

Initial access → privilege escalation → credential theft → network discovery → backup discovery → lateral movement → data theft → security-tool disruption → file encryption → ransom demand

Modern ransomware attacks can therefore be considerably more complicated than simply finding a malicious .exe file on one computer.

Attackers may attempt to compromise:

• Windows workstations
• Windows Servers
• Active Directory
• File servers
• NAS devices
• Shared folders
• Database servers
• Hypervisors
• Virtual machines
• Backup servers
• Cloud credentials
• Remote Desktop servers
• VPN accounts

Some ransomware operators also steal data before encryption and threaten to publish it. Therefore, successful file recovery does not necessarily mean the entire security incident has been resolved.

2. First Action: Isolate the Infected Computer

If ransomware is actively encrypting files, containment is more urgent than file recovery.

Immediately isolate affected computers from the network.

Disconnect:

• Ethernet cables
• Wi-Fi
• VPN connections
• Network shares
• External USB drives
• Backup drives
• NAS connections
• Mapped drives

If multiple computers are affected, consider isolating affected network segments.

Do not reconnect the machine merely to download a recovery program.

Use another known-clean computer to research the ransomware and obtain trusted recovery tools.

3. Do Not Immediately Delete the Encrypted Files

Encrypted files may still be useful.

A decryptor could become available later, even if one is unavailable today.

For example:

Original file:

Accounts.xlsx

Encrypted version:

Accounts.xlsx.locked

Another ransomware family might produce:

Accounts.xlsx.xyz123

Keep copies of encrypted files, particularly important business data.

Ideally, maintain:

Copy 1: untouched evidence/archive

Copy 2: working copy for recovery/decryption testing

Never test unknown decryptors against the only copy of important encrypted data.

4. Preserve the Ransom Note

Do not immediately delete the ransom note.

It may contain information useful for identifying the ransomware family.

Common ransom-note filenames may resemble:

README.txt

RECOVER_FILES.txt

HOW_TO_DECRYPT.txt

DECRYPT_INSTRUCTIONS.html

RESTORE_FILES.txt

Preserve the note for forensic analysis.

Do not use contact details or links in it merely to investigate the ransomware unless your incident-response process specifically requires doing so.

5. Record the Encrypted File Extension

Look at several affected files.

For example:

invoice.xlsx.abcd

database.bak.abcd

photo.jpg.abcd

Record the new extension.

Also check whether filenames themselves were changed.

This information, combined with the ransom note, can help identify the ransomware family.

6. Determine the Scope of the Attack

Before restoring anything, determine what has been affected.

Check:

• Local drives
• File servers
• Network shares
• NAS storage
• External drives
• Backup repositories
• Virtual machines
• Database servers
• OneDrive
• SharePoint
• Cloud storage
• Remote Desktop servers

For organizations, create an inventory such as:

System	Status	Data Status	Backup Available
Accounting Server	Encrypted	Critical	Yes
File Server	Encrypted	Critical	Yes
PC-01	Encrypted	Medium	No
PC-02	Clean	Safe	Yes
NAS	Partially affected	Critical	Snapshot available

This prevents an unstructured recovery effort.

7. Preserve Evidence Before Major Changes

For serious business incidents, consider preserving forensic evidence before rebuilding systems.

CISA recommends capturing, where feasible, system images and memory from representative affected devices and preserving relevant logs and malware-related evidence.

Potential evidence includes:

• Disk image
• Memory capture
• Windows Event Logs
• Firewall logs
• VPN logs
• EDR logs
• Antivirus logs
• Authentication logs
• Suspicious executables
• Ransom notes
• Scheduled tasks
• Registry changes
• PowerShell logs
• Remote-access logs

This evidence may help determine how attackers entered the network and whether persistence remains.

8. Identify the Ransomware Variant

Correct identification is extremely important.

Do not download random programs claiming:

"Universal Ransomware Decryptor"

There is no universal decryptor capable of decrypting every ransomware family.

Identification may involve:

• Encrypted file extension
• Ransom-note filename
• Ransom-note contents
• Email addresses in the ransom note
• File naming pattern
• Malware sample
• Security-product detection
• Incident-response analysis

Once the family is identified, investigate whether a legitimate decryptor exists.

9. Check the No More Ransom Project

One of the most useful resources for ransomware victims is the No More Ransom project.

No More Ransom Decryption Tools

Its decryptor collection includes tools for numerous ransomware families. The project also warns that malware should be removed before decryption so files are not repeatedly encrypted.

Important

A decryptor designed for one ransomware family should not be assumed to work against another.

Always verify:

• Ransomware family
• Ransomware version
• Supported extension
• Tool developer
• Tool documentation

Create a backup of encrypted files before attempting decryption.

10. Recovery Method 1: Restore from Offline Backups

A clean backup is generally the safest and most reliable ransomware recovery method.

However, do not immediately connect your backup disk to an infected computer.

First ensure that the ransomware has been removed or that recovery is taking place on clean systems.

CISA specifically recommends maintaining offline, encrypted backups and regularly testing their integrity because ransomware may attempt to encrypt or delete backups that remain accessible from compromised systems.

A good recovery process is:

Contain → Investigate → Eradicate → Rebuild/Clean → Verify → Restore

not:

Encrypted → Connect backup immediately → Restore

The second approach risks encrypting the backup as well.

11. Check Multiple Backup Generations

Do not assume the newest backup is safe.

Suppose backups exist for:

• Monday
• Tuesday
• Wednesday
• Thursday
• Friday

and ransomware was discovered Friday.

The initial compromise might have occurred days earlier.

Attackers sometimes remain inside networks before launching encryption.

Therefore, verify backup integrity and determine an appropriate recovery point.

12. Scan Backups Before Restoration

A backup can contain malware even if the backed-up documents themselves are not encrypted.

Before restoring production systems:

1. Establish a clean recovery environment.
2. Patch the operating system.
3. Update security software.
4. Scan backup contents where appropriate.
5. Check suspicious executables and scripts.
6. Restore a small sample.
7. Verify applications and data.
8. Perform full restoration.

13. Recovery Method 2: OneDrive Recovery

Organizations using Microsoft 365 may have additional recovery possibilities.

Microsoft states that Microsoft 365 subscribers can use Restore your OneDrive to undo file and folder actions within the previous 30 days, including situations where files were corrupted or infected by malware.

Possible recovery methods include:

• Restore your OneDrive
• Recycle Bin
• Previous file versions
• SharePoint document-library recovery

Microsoft's official instructions are available here:

Microsoft – Restore Your OneDrive

This can be extremely useful when ransomware encrypted files inside a locally synchronized OneDrive folder and those changes synchronized to the cloud.

14. OneDrive Recycle Bin Recovery

If ransomware or an attacker deleted files rather than merely encrypting them, inspect the OneDrive Recycle Bin.

Microsoft notes that deleted OneDrive files or folders may be recoverable from the Recycle Bin.

Do this before assuming deleted cloud files are permanently lost.

15. Recovery Method 3: File Version History

Cloud-storage systems may preserve earlier versions of files.

Suppose ransomware changed:

Report.xlsx

at 3:15 PM.

A clean version may exist from:

10:00 AM
Yesterday
Three days earlier

Instead of attempting cryptographic recovery, restoring a clean historical version may solve the problem.

This can be particularly valuable for:

• Office documents
• Accounting exports
• PDFs
• Project files
• Shared documents

16. Recovery Method 4: Windows Previous Versions

Windows can sometimes provide earlier versions of files through Volume Shadow Copy technology.

Right-click an affected file or folder and check:

Properties → Previous Versions

If snapshots survived the attack, previous versions may be available.

However, many ransomware families attempt to remove shadow copies, so this method should be considered a possible recovery path rather than a guaranteed solution.

17. Check Volume Shadow Copies

An administrator can inspect available shadow copies using:

vssadmin list shadows

You can also inspect VSS writers:

vssadmin list writers

Do not execute commands that delete shadow copies during ransomware recovery.

For example, avoid destructive commands involving:

vssadmin delete shadows

until the incident has been fully investigated.

18. Recovery Method 5: NAS Snapshots

If ransomware encrypted a mapped NAS share, investigate whether the NAS maintains snapshots.

Many enterprise and business NAS platforms support snapshot technologies.

A snapshot from before the encryption event may allow administrators to restore:

• Shared folders
• User directories
• Databases
• Department folders
• Project data

However, first isolate and secure the compromised credentials or endpoint responsible for the original attack.

Otherwise, restored NAS data may simply be encrypted again.

19. Recovery Method 6: Virtual Machine Backups and Snapshots

For ransomware affecting virtual servers, investigate:

• Hypervisor snapshots
• VM-level backups
• Image backups
• Replica servers
• Disaster-recovery copies
• Storage snapshots

Examples include environments based on:

• Hyper-V
• VMware
• Proxmox
• Cloud virtual machines

A clean VM backup may allow substantially faster recovery than rebuilding a complex server manually.

But snapshots should not be treated as the only long-term backup strategy.

20. Recovering Databases

Database recovery requires special care.

Affected systems might contain:

• Microsoft SQL Server
• MySQL
• MariaDB
• PostgreSQL
• ERP databases
• Accounting databases

Look for:

• Full database backups
• Differential backups
• Transaction-log backups
• Application backups
• Replicas
• Cloud backups
• Offline backup copies

Do not simply copy encrypted database files over a newly installed database server and expect them to work.

Follow the database application's supported restore procedure.

21. Recovering Accounting and ERP Data

Ransomware affecting accounting systems can cause serious operational disruption.

Potential targets include:

• Tally data
• ERP databases
• GST data
• Payroll
• Inventory systems
• Billing software
• SQL databases

Search for backup copies on:

• Dedicated backup servers
• External disks
• NAS
• Cloud backup
• Offsite storage
• Application backup folders

Before restoring accounting data, verify both the data backup and the application environment.

22. Can Antivirus Decrypt Ransomware Files?

Usually, antivirus software performs a different function.

Antivirus or EDR may:

• Detect ransomware
• Quarantine malware
• Stop malicious processes
• Block known behavior
• Detect persistence
• Remove malicious files

But removing ransomware does not automatically decrypt already-encrypted files.

Think of the process as two separate problems:

Problem 1: Remove the attacker/malware

Problem 2: Recover the encrypted data

Both must be addressed.

23. Should You Run Antivirus Before Recovery?

Security scanning is important, but timing matters in serious incidents.

For a home PC with limited business significance, a trusted antivirus scan may be appropriate after isolation.

For a business server or widespread attack, immediately deleting everything detected by antivirus could destroy useful forensic evidence.

Organizations should consider preserving evidence first and then performing eradication under an incident-response plan.

24. Can File Recovery Software Recover Ransomware Files?

Sometimes—but this is often misunderstood.

Programs that recover deleted files generally cannot decrypt cryptographically encrypted data.

However, some ransomware implementations may:

1. Read the original file.
2. Create an encrypted copy.
3. Delete the original.

If the deleted original data remains recoverable and has not been overwritten, forensic file-recovery software may potentially retrieve some original files.

Success depends on:

• HDD versus SSD
• TRIM status
• Overwriting
• Filesystem
• Ransomware behavior
• Disk activity after infection

On SSDs with TRIM enabled, deleted-file recovery may be much less successful.

25. Avoid Excessive Disk Activity

If deleted-file recovery is being considered, minimize writes to the affected disk.

Avoid:

• Installing numerous programs
• Downloading large files
• Running unnecessary updates
• Copying data onto the affected disk
• Defragmenting
• Repeatedly modifying files

Every write can potentially overwrite recoverable deleted data.

For high-value cases, work from a forensic image or cloned disk rather than the original storage device.

26. Never Recover Files Back to the Same Drive

If using file-recovery software, save recovered data to another physical storage device.

Example:

Affected disk:

C:

Recovery destination:

E:\RecoveredData

Do not recover:

C: → C:

because writing recovered files onto the source disk can overwrite other recoverable data.

27. Do Not Rename Encrypted Files Randomly

Changing:

accounts.xlsx.locked

to:

accounts.xlsx

does not decrypt the file.

The internal contents remain encrypted.

Similarly, changing extensions from:

.encrypted

to:

.docx

will not restore a document.

Keep original filenames and extensions unless the documentation for a verified decryptor specifically instructs otherwise.

28. Test Decryption on Copies

Never begin decryption against the only available encrypted dataset.

Instead:

1. Copy several encrypted files.
2. Include different file formats.
3. Keep originals untouched.
4. Run the legitimate decryptor against test copies.
5. Open the resulting files.
6. Verify their contents.
7. Check file sizes.
8. Validate important databases separately.

Only after successful testing should large-scale decryption be considered.

29. Do Not Trust Random "Decryptor" Websites

Ransomware victims are attractive targets for secondary scams.

Avoid downloading unknown recovery programs from random websites promising:

• Guaranteed decryption
• Universal decryptor
• Instant ransomware recovery
• 100% recovery
• Secret master key

Prefer reputable security vendors, government cybersecurity organizations and established projects such as No More Ransom.

30. Should You Pay the Ransom?

Paying should not be treated as a normal recovery method.

Payment does not guarantee:

• A working decryptor
• Complete file recovery
• Deletion of stolen data
• No future extortion
• No reinfection
• That attackers retained the required key

Organizations should involve management, legal counsel, cybersecurity specialists, insurers where applicable, and appropriate authorities when dealing with extortion decisions and regulatory obligations.

31. Rebuild Versus Clean the Existing System

For significant ransomware incidents, rebuilding compromised systems from trusted media can provide greater confidence than merely deleting detected malware.

A recovery process may involve:

1. Preserve evidence.
2. Wipe compromised operating-system disks where appropriate.
3. Reinstall from trusted installation media.
4. Apply updates.
5. Install drivers.
6. Install applications.
7. Deploy endpoint protection.
8. Apply security policies.
9. Restore clean data.
10. Test applications.
11. Reconnect under controlled conditions.

CISA recommends restoring data to clean systems while taking care not to reintroduce infected systems into the recovery environment.

32. Change Passwords After a Ransomware Attack

Assume credentials may have been compromised, particularly in a network-wide incident.

Consider resetting:

• Domain administrator passwords
• Local administrator passwords
• Microsoft 365 accounts
• Google Workspace accounts
• VPN credentials
• RDP credentials
• Backup administrator accounts
• NAS accounts
• Database accounts
• Firewall accounts
• Cloud administrator credentials
• Service accounts where appropriate

Password changes should ideally be performed from known-clean systems.

Enable MFA wherever supported.

33. Investigate the Original Entry Point

Restoring files without fixing the original security weakness can lead to another attack.

Investigate possible entry points such as:

• Exposed Remote Desktop
• Stolen VPN credentials
• Phishing email
• Malicious attachment
• Unpatched server
• Vulnerable web application
• Weak administrator password
• Compromised remote-support software
• Stolen session/token
• Malicious PowerShell
• Exploited firewall or VPN appliance
• Compromised third-party account

Recovery is incomplete until the entry point and persistence mechanisms have been addressed.

34. Check for Persistence

Attackers may leave mechanisms allowing them to return.

Investigate:

• Scheduled Tasks
• Windows Services
• Startup folders
• Registry Run keys
• Local users
• Domain users
• Administrator-group membership
• Remote-access software
• PowerShell scripts
• WMI persistence
• Browser extensions
• Startup scripts
• Group Policy changes

Simply removing the ransomware executable may not remove the attacker.

35. Verify Active Directory

If ransomware affected a Windows domain environment, investigate Active Directory carefully.

Review:

• Domain Admins
• Enterprise Admins
• Newly created accounts
• Password changes
• Group membership
• Group Policy
• Domain controllers
• Authentication logs
• Service accounts
• Remote logins

If domain-level administrative credentials were compromised, restoring file servers alone may not be sufficient.

36. Check Backup Infrastructure

Attackers frequently target backups.

Review:

• Backup administrator logins
• Backup repositories
• Backup retention
• Deleted recovery points
• Changed backup jobs
• Disabled backup services
• NAS snapshots
• Cloud backup accounts

Do not assume a backup is trustworthy merely because the backup job reports Successful.

Actually test restoration.

37. Recommended Recovery Priority

For a business, restore systems according to business impact.

A practical order might be:

Priority 1 – Identity and Security

• Active Directory
• DNS
• Authentication
• Firewall
• Security monitoring

Priority 2 – Critical Applications

• ERP
• Accounting
• Database servers
• Production systems

Priority 3 – File Services

• Department shares
• Document repositories
• User folders

Priority 4 – Endpoints

• Employee desktops
• Laptops
• Non-critical systems

The exact order depends on organizational dependencies.

38. Recommended Backup Strategy After Recovery

A ransomware incident often exposes weaknesses in backup architecture.

A useful baseline is the 3-2-1 principle:

3 copies of important data

2 different storage types

1 copy offsite/offline

For stronger ransomware resilience, organizations should also consider:

• Immutable backups
• Air-gapped backups
• Backup MFA
• Separate backup credentials
• Restricted backup-console access
• Versioning
• Multiple retention periods
• Automated recovery testing
• Backup monitoring

CISA specifically recommends offline backups because ransomware may attempt to encrypt or delete accessible backup copies.

39. Example Ransomware-Resistant Backup Architecture

A business might use:

Production Server

↓

Daily Backup Repository

↓

Immutable/Protected Backup Storage

↓

Offsite Cloud Backup

↓

Periodic Offline Backup

This provides several recovery layers.

If ransomware reaches production storage, the organization still has independent recovery options.

40. Example Recovery Scenario

Consider a company with:

• Windows Server
• 20 workstations
• Accounting software
• Shared folders
• NAS
• Cloud backup

At 9:00 AM employees discover encrypted files.

A structured response could be:

9:05 AM – Disconnect affected endpoints.

9:10 AM – Isolate server network access.

9:20 AM – Protect backup infrastructure.

9:30 AM – Preserve logs and ransomware evidence.

10:00 AM – Determine ransomware family and affected scope.

11:00 AM – Establish clean recovery network.

12:00 PM – Verify last known-good backup.

1:00 PM – Rebuild critical server.

3:00 PM – Restore accounting/database data.

5:00 PM – Validate critical services.

The actual timeline can range from hours to days or longer depending on attack severity.

42. What Not to Do After Ransomware

Avoid these common mistakes:

Do not format the machine immediately.

Do not delete encrypted files.

Do not connect clean backups to infected systems.

Do not randomly download decryptors.

Do not assume antivirus removal recovered the data.

Do not rename encrypted extensions expecting files to open.

Do not restore the entire network before fixing the entry point.

Do not assume cloud-synchronized files are automatically safe.

Do not immediately destroy forensic evidence in a serious business incident.

Do not trust a backup without testing it.

43. When Professional Recovery Assistance Is Recommended

Professional incident-response or forensic assistance should be strongly considered when:

• No backup exists.
• Multiple servers are encrypted.
• Active Directory is compromised.
• Backup infrastructure was attacked.
• Large amounts of business data are affected.
• Customer or confidential data may have been stolen.
• Critical databases are damaged.
• The ransomware family cannot be identified.
• Legal or regulatory reporting may apply.
• Business operations are severely disrupted.

For high-value systems, experimentation can make recovery more difficult.

44. Frequently Asked Questions (FAQ)

Q1. Can ransomware-encrypted files be recovered?

Sometimes. Recovery may be possible through backups, cloud version history, snapshots, legitimate decryptors or limited forensic recovery methods.

Q2. Can antivirus decrypt ransomware files?

Normally no. Antivirus can detect and remove malware, but encrypted files generally require restoration or a ransomware-specific decryptor.

Q3. Should I delete encrypted files?

No. Preserve them because a compatible decryptor may become available later.

Q4. Should I format my computer after ransomware?

Not immediately. First preserve important evidence and encrypted data and determine your recovery options. Rebuilding may later be appropriate.

Q5. Can Windows System Restore recover ransomware files?

Usually System Restore should not be considered a primary file-backup mechanism. Previous Versions or surviving shadow copies may sometimes help.

Q6. Can Previous Versions recover encrypted files?

Possibly, if suitable shadow copies still exist and the ransomware did not remove them.

Q7. Can OneDrive recover ransomware-encrypted files?

Potentially yes. Microsoft provides OneDrive restoration and version/recycle-bin capabilities that may help recover earlier states.

Q8. Can a NAS recover ransomware files?

Possibly. Check whether snapshots, replication or independent backups are available.

Q9. Is there a universal ransomware decryptor?

No. Decryptors normally target specific ransomware families or versions.

Q10. Where can I find legitimate ransomware decryptors?

The No More Ransom project maintains a collection of decryptors from established security organizations.

Q11. Can data-recovery software decrypt ransomware?

Normally no. File-recovery programs may occasionally recover deleted original copies, but they cannot generally break strong ransomware encryption.

Q12. Should I pay the ransom?

Payment does not guarantee successful recovery. Businesses should involve appropriate incident-response, legal and management resources before making decisions concerning extortion.

Q13. Can ransomware encrypt external USB drives?

Yes, if the drive is connected and accessible when the ransomware runs.

Q14. Can ransomware encrypt network drives?

Yes. Accessible mapped drives and network shares can be targeted.

Q15. Can ransomware attack backups?

Yes. This is why offline, isolated or immutable backup strategies are important.

Q16. How do I know whether my backup is safe?

Determine when the compromise began, scan and inspect the recovery environment, and test restoration before returning the system to production.

Q17. Should passwords be changed after ransomware?

Yes, when credential compromise is possible. Prioritize administrator, remote-access, cloud, backup and privileged accounts.

Q18. Can ransomware come back after files are restored?

Yes. If the original vulnerability, compromised credentials or attacker persistence remains, systems can be compromised again.

Q19. What is the safest way to restore ransomware data?

Generally, restore a verified known-good backup into a clean and secured environment after containing and eradicating the threat.

Q20. What is the best protection against ransomware data loss?

Layered protection is strongest: patched systems, MFA, endpoint security, network controls, least privilege, monitoring and multiple tested backups—including an offline or immutable recovery copy.

Conclusion

Recovering files after ransomware is not simply a matter of finding a decryption program.

A successful ransomware recovery requires a structured approach:

Isolate → Preserve → Investigate → Identify → Eradicate → Rebuild → Restore → Verify → Monitor

The best recovery option is normally a clean and independently protected backup. When backups are unavailable, investigate cloud version history, snapshots and legitimate ransomware-specific decryptors before considering more complicated forensic recovery methods.

Most importantly, do not restore data into an environment that remains compromised. A perfectly restored backup can be encrypted again if stolen credentials, malicious persistence or the original vulnerability remain active.

Ransomware recovery should therefore address two equally important objectives:

Recover the data and remove the security weakness that allowed the attack to happen.

Disclaimer

This article is provided for educational and general technical-information purposes only. Ransomware incidents vary significantly, and incorrect recovery actions can result in permanent data loss, destruction of forensic evidence or reinfection. Organizations handling critical, confidential, financial, customer or regulated information should consult qualified cybersecurity, incident-response, forensic, legal and compliance professionals before taking major recovery actions.
