Ransomware Data Recovery

Sometimes. Ransomware decryption without the attacker's key works only for families with a known weakness or published keys. For the rest we recover the data another way: many families encrypt only part of each large file, so databases, virtual disks and backups can often be rebuilt from the parts that were never encrypted. The free assessment tells you which applies.

We work on copies, never the originals. We identify the family and measure how much of each file is really encrypted, then recover from what survived: intact database pages, the contents of virtual disks, backup blocks, shadow copies and deleted originals. Small files that were encrypted completely usually cannot be recovered without the key, and we say so.

No. Ransomware removal means cleaning the malware off the systems; ransomware recovery means getting the data back. Have the recovery assessed first: reinstalling or cleaning a server before it has been imaged can destroy data that was still recoverable.

Isolate the affected systems, keep the ransom note and a few encrypted samples, and do not restart or reinstall. We assess the samples free of charge, tell you what is recoverable, recover the data from images of the disks and return it verified. Rebuilding and hardening the systems follows once the data is safe.

Often. ESXi ransomware and Hyper-V ransomware usually encrypt the large VMDK and VHDX files only in part, because encrypting them completely takes too long. The file systems and databases inside can frequently be rebuilt from the parts that were not encrypted; that is what Hyper-V ransomware recovery and ESXi recovery consist of.

It depends on the variant. Some families have known weaknesses or published keys; most do not. Where technically feasible, we investigate available recovery and decryption options and tell you clearly what is realistic before any chargeable work.

We advise against it as a first option. Payment doesn't guarantee working decryption, may be restricted in your jurisdiction, and funds further attacks. Recovery options should be assessed first.

Often, yes — through backups, storage-level remnants, partial-encryption recovery or, for some variants, published decryption keys. We assess every available source before payment is even considered.

Restore onto clean, isolated infrastructure — never back into the compromised environment. We image affected systems first, then recover onto separate storage so nothing is restored into a network that may still be compromised.

Often, yes. Partially encrypted backups, storage-level remnants and snapshots frequently contain recoverable data. This is exactly what the assessment determines.

Speed, mainly. Fully encrypting a multi-gigabyte database, virtual disk or backup file takes real time per host, and most operators are racing to hit as many systems across a network as possible before defenders notice and start isolating them. Encrypting just a file's header and a handful of blocks is usually enough to make it unusable to the application that owns it — which is all the attacker needs for leverage — while leaving most of the actual data untouched underneath. That gap is exactly what partial-encryption recovery works from.

No contact with attackers is needed. A copy of the ransom note and a few encrypted samples help identify the variant.

A ransom note or a couple of encrypted file samples are usually enough. Free identification services like ID Ransomware and the No More Ransom Project (a Europol-backed initiative) can often name the exact family from those samples, and their site also lists free decryptor tools for variants that have been publicly broken. We check those first — no reason to pay for what's already free — before moving to file-level or backup recovery for the variants that don't have one.

Yes. We preserve images and logs in a forensically sound manner and can provide documentation of what was affected and recovered.

Isolate affected systems from the network immediately — disconnect, don't reboot or shut down, and don't restore or run cleanup tools yet. Those actions can destroy the exact evidence and remnants that make recovery possible. Preserve the ransom note and current state, then get an assessment before deciding anything else, including whether to involve law enforcement or your insurer.

No. We assess your case and tell you what is recoverable before you pay anything.

Then you do not pay for the recovery — no data, no charge.

Yes. We sign a non-disclosure agreement before you send any data.

Yes. We assess and recover ransomware-encrypted servers, databases, VMs and backups for organizations across these and other Indian cities — most of the work is image-based and remote, with secure courier for physical storage and on-site incident response available where the situation calls for it.

Assessment starts immediately on contact, regardless of city, since the work is image-based rather than requiring an engineer to already be on-site. For Chennai and other major Indian metros, on-site incident response can also be arranged where the situation calls for it, alongside the remote assessment already under way.

Yes. AS is a data recovery company whose main work is ransomware recovery services: recovering data from ransomware-encrypted servers, databases, virtual machines and backups. We are not a negotiation firm and we do not sell decryptors.

Our ransomware recovery experts identify the ransomware, measure how each file was encrypted, and recover the data the encryption did not reach. Clients also use us as a ransomware recovery consultant alongside their own IT team or incident responder: we answer the question of what is recoverable while they rebuild.

Yes. Business ransomware recovery is most of what we do, from a single accounting server to enterprise ransomware recovery across ESXi hosts, SAN storage and backup repositories. The ransomware recovery solutions differ by case: database extraction, virtual disk recovery, backup recovery or file repair.

They are two jobs. Ransomware removal means cleaning and rebuilding the systems, and that is ransomware incident response, done by your IT team or a responder, with our incident response support where needed. Ransomware attack recovery of the data itself is our core work.

Not in the sense of breaking the encryption: modern ransomware cannot be decrypted without the attacker's key. Where a public decryptor exists we use it. Otherwise ransomware file recovery comes from the parts of large files that were never encrypted, and from backups and shadow copies. Small files that were encrypted completely cannot be recovered without the key.

Often in large part. Ransomware server recovery starts from the encrypted disks or virtual disks: we read the file systems, databases and backups inside them around the encrypted regions. Encrypted server data recovery works best when nothing has been formatted or reinstalled since the attack.

Ransomware database recovery is our speciality. Database files are large, so they are usually only partly encrypted, and the tables can be extracted from the intact pages. We do this for SQL Server, Oracle, MySQL and SAP HANA: SQL database ransomware recovery, MySQL ransomware recovery and SAP HANA ransomware recovery follow the same principle with engine-specific tools.

Yes. NAS ransomware recovery covers Synology, QNAP and similar devices. VMware ransomware recovery and ESXi ransomware recovery work on the encrypted VMDK files of the datastore. Veeam ransomware recovery, and ransomware backup recovery in general, reads the data blocks that are still intact inside encrypted VBK and other backup files.

Worldwide, remotely, from our lab in India. We provide ransomware recovery services in India, the UK, the USA, Dubai and the rest of the UAE, Saudi Arabia and other countries. Files are uploaded over an encrypted channel or media is shipped to the lab; we have no offices abroad.

A disaster recovery plan restores systems from clean backups. Ransomware disaster recovery fails when the backups were encrypted too, and that is the point at which data recovery from the encrypted files becomes the only route. We also help test backups so that the plan works next time.
