Deleted originals
Many strains write an encrypted copy, then delete the original. We carve those originals back off the disk before they're overwritten.

How files come back
Six ways to restore data without a key.
Ransomware is designed to look final. In practice, attacks leave gaps — and our engineers know where to look.
Shadow copies & snapshots
Windows Volume Shadow Copies, NAS snapshots and VM snapshots that the attack missed or only partly deleted.
Partly encrypted files
To work fast, many strains encrypt only part of each file. Large databases, Tally data, virtual disks and videos can often be rebuilt from the untouched parts.
Known free decryptors
Some variants have published keys or flaws, such as those listed by the No More Ransom project. We test them safely on copies, never on your originals.
Backups & cloud versions
Damaged backup drives, NAS backup jobs, old disk images and OneDrive or Google Drive version history.
Database & Tally repair
SQL Server, MySQL, Tally, Busy and QuickBooks files rebuilt from recovered fragments and checked for consistency.
Our policy
We don't pay criminals. We out-work them.
Paying a ransom funds the next attack, may expose you to legal risk, and doesn't guarantee a working key — attackers' decryptors are often slow, buggy or never arrive.
No ransom payments, no negotiation
We never contact attackers, pay ransoms or act as a go-between.
Forensic images first
Every affected drive is imaged before anything else. All recovery work happens on the copies.
Clean, confidential handover
Restored files are scanned before return, under NDA, and your data never leaves our secure facility unencrypted.
What you receive
Your files back — and the full picture.
You'll know exactly what was recovered, what couldn't be, and what to fix so it doesn't happen again.
- Restored files in their original folder structure, on a new clean drive
- A file-by-file status list: fully restored, partly restored, or not recoverable
- The ransomware strain identified, with the indicators we found
- An incident report for insurance, auditors or CERT-In on request
- Practical next steps: offline backups, patching and access controls
Honest answer: a file that's fully encrypted, with no surviving original, snapshot, backup or known decryptor, can't be opened without the attacker's key. Our free assessment shows you what's recoverable, file by file, before you pay anything.

Ransomware recovery FAQ
Questions people ask us.
Straight answers about restoring files after a ransomware attack.
Hit right now? Send us the ransom note for a free first assessment.
Ask on WhatsAppCan files encrypted by ransomware be recovered without paying?
Often, yes. Many ransomware strains delete the original files after writing encrypted copies, encrypt only part of each file, or leave shadow copies and backups behind. Data Doctor Hub recovers deleted originals, rebuilds partly encrypted files, restores snapshots and backups, and applies known free decryptors where they exist. A free assessment shows what is recoverable before any payment.
Do you pay the ransom or negotiate with the attackers?
No. Data Doctor Hub never pays ransoms, contacts attackers or negotiates on a customer's behalf. Recovery is done only with technical methods, working on forensic copies of the affected drives.
Which ransomware variants can you recover from?
Data Doctor Hub works with files hit by LockBit, Phobos, Makop, STOP/Djvu, Dharma (CrySIS), Mallox, Akira, BlackCat (ALPHV), Medusa, Babuk, Conti, QNAP DeadBolt and Qlocker, and others. What can be restored depends on how the specific attack behaved, not just the variant's name.
Is there a free decryptor for my ransomware?
Sometimes. Security researchers publish free decryptors for some variants, many listed on the No More Ransom project. Data Doctor Hub identifies the exact variant from the ransom note and an encrypted sample, and tests any available decryptor safely on copies of your files.
What should I do immediately after a ransomware attack?
Disconnect infected systems from the network, or power them off if you can't isolate them. Don't reinstall Windows, format drives, run clean-up tools or rename encrypted files. Keep the ransom note, don't contact the attackers, and call a recovery specialist. Report the crime on the 1930 helpline or at cybercrime.gov.in.
Can encrypted Tally, SQL Server or other database files be restored?
In many cases. Large database and Tally files are often only partly encrypted, so their data can be rebuilt from the unencrypted parts and checked for consistency. Deleted originals and older copies on the same drive are also searched.
Our NAS (QNAP or Synology) was hit. Can the data be recovered?
Often, yes. NAS attacks such as DeadBolt or Qlocker frequently leave snapshots, unencrypted remnants or recoverable originals on the disks. The drives are removed and imaged in the lab, and the RAID volume is rebuilt from the images.
How long does ransomware recovery take, and what does it cost?
Data Doctor Hub aims to complete the free assessment within 24–48 hours, and business-critical cases are prioritised. The quote depends on the number of systems, the data volume and the method needed, and it is confirmed before work starts. If nothing can be recovered, there is no charge.
Should I report a ransomware attack?
Yes. In India, report it on the National Cyber Crime Helpline 1930 or at cybercrime.gov.in. Organisations may also need to report cyber incidents to CERT-In within 6 hours of noticing them. Data Doctor Hub can provide an incident report to support these reports and insurance claims.
