Ransomware Data Recovery Swindon

You come in to find all of your documents with an unusual extension and a ransom demand in each folder, with the criminals claiming their decryptor is the only way out. The drives usually say otherwise. Drives from encrypted PCs, servers and NAS devices in Swindon and Royal Wootton Bassett are examined here for all the lawful routes to recovery, and paying money to the attackers will never be one of them.

We provide a free diagnostic on every ransomware job. Every job gets one fixed quote in writing before the work starts.

In most cases you only pay if we recover your data. Electronic and mechanical failures and chip-level work are 50% upfront, with the balance only if we recover your data, while BitLocker, ransomware, DVR and forensic jobs are paid upfront once you accept the fixed quote. You'll find full pricing on the data recovery cost page.

// top 20 faults we recover from

The twenty ways they fail

Each ransomware job begins with matching the symptoms to what caused the issue, and these twenty cover almost everything that passes through our doors.

Whole PC encrypted

Every user folder was locked in one overnight run, which is the single-machine attack that keeps a constant flow of jobs coming onto our intake shelf.

NAS shares encrypted

Synology and QNAP boxes connected to the internet are popular with attackers, but the snapshots underneath the shares tend to survive the attack.

ESXi datastore swept

Hypervisor strains encrypt the datastore one VMDK at a time, which means a whole virtual estate goes offline at once from the same attack.

Partial encryption of big files

Some families are built for speed, so they only encrypt the front portion of each large file, and the remaining portions of databases and archives can still be used.

Shadow copies purged

Before encrypting, the malware runs vssadmin, and deleted restore points can sometimes be carved back out of free space.

Backup drive hit too

The USB 'backup' was plugged in at the time, so it could be reached and it got encrypted too, but earlier versions and remnants still count.

Double extortion

Data theft happened before the files were locked and publication is being threatened. As such, we scope what left the network for the insurers and the ICO.

Boot-locked machine

A ransom screen is shown instead of Windows, so the drive is removed and imaged, and the data is examined beneath the lock.

Databases caught mid-write

SQL and Exchange files that were caught mid write end up partially encrypted, and salvage then works page by page from the captured image.

Still-live infection

If a NAS re-encrypts every restore, the device is still under the attacker's control, so it's isolated first and recovery then happens from images only.

Strain nobody recognises

The unknown extension is fingerprinted against the strain databases to find the family it belongs to and any published weakness.

Note without encryption

Scareware displays ransom demands over files that are still intact, and some runs crash early, so a bench check works out whether you have suffered an actual loss or just a fright.

Akira / LockBit business hits

The current heavyweights of corporate attacks run thorough deletion passes that still don't remove everything.

STOP/Djvu home infections

It gets in through cracked downloads, and where an older offline key variant is involved, there is a free decryptor that is applied lawfully.

Encrypted copy, deleted original

Some ransomware families make a duplicate copy of your files and then delete your original, which leaves the original sitting in free space, ready to be carved out.

RDP door left open

Dharma and Phobos still get in through exposed Remote Desktop, and the encryption follows within hours of the login.

Cloud sync pushed it upstream

OneDrive and Drive dutifully synced the encrypted data over the good data, so version history and remnant data are checked at both ends.

Hyper-V estate locked

Host-based VHDX encryption takes all of the guests down at once, but due to quirks in partial encryption, the guests can often still be rebuilt.

Exfiltration without encryption

Nothing is actually locked, but all the data has been copied and there is extortion by threat of a leak, so forensic scoping becomes the focus rather than recovery.

Backup rotation caught mid-cycle

The single disk that was connected on the night of the attack was the one that got hit. The sets that were out of rotation, along with carved remnants of data, fill the gap.

What the attack actually did

The malware worked through your storage encrypting the files one after another using entirely standard encryption. AES was used to encrypt the content of each file, and the AES keys were then sealed under an asymmetric key, with the private half staying with the attackers. The odd extension is the signature added by that particular strain, and a note is left once the run is complete. Serious families will also search for shadow copies, reachable backups and any shares the compromised account could get to, hence the smug tone of the demand. What it never admits is what the run missed, and there is almost always something.

The lawful ways back

There is no lab anywhere in the world that can brute force properly built encryption, so if any firm tells you otherwise, they are selling you a story. Realistic work looks for where the attack fell short. That could be snapshots and shadow copies the purge missed, backups the malware couldn't get to, originals that were deleted rather than encrypted when the strain worked on a copy, temporary files and fragments recovered from slack and free space, broken NAS or RAID structures rebuilt until clean data shows through, and the small number of families with published flaws that let a free decryptor be applied lawfully. Your free assessment will show which of these ways out apply in your situation.

Our position on paying

We do not pay ransoms, we don't pass messages to attackers, and we will never encourage a client to pay. Giving an attacker money pays for their next campaign, guarantees you nothing, and criminal decryptors have a habit of wrecking the very files they claim to release. What we give you is every technical route tried, along with a written record of what came back and what stayed lost. If insurers and advisers later push a company towards negotiating, that decision is up to them. Our role was to make sure the technical answer came first.

// the equipment we use

A professional lab, not software guesswork

Every ransomware case we handle is treated as a forensic incident from the first minute, which means it is isolated, imaged and documented:

Air-gapped imaging bench

Media from an incident is kept completely off the lab network and worked on at an isolated bench, so it can't spread, phone home or carry on encrypting data.

Hardware write-blockers

All incident drives are captured behind write-blockers before they are examined; all recovery is done on the copies and the original drives stay sealed.

VSS / shadow-copy carving

Free space is searched for remaining shadow copies and also NAS snapshot data which the purge missed, and if anything is found, it is rebuilt into usable restore points.

Strain ID & decryptor lookup

From the ransom note and a couple of samples, the family is identified and then checked against reputable public decryptor sources (such as No More Ransom and vendor releases) to see if there is a lawful key available.

Remnant & free-space carving

Unencrypted originals, temporary files and partial copies are carved out of free space: the debris every fast encryption run leaves behind.

Forensic logging & reporting

Strain, blast radius and results are logged throughout, giving you the paperwork that insurers, regulators and your own post-incident review will all ask for.

The honest sources of recovered data

Two commitments in writing before any work starts: no lab on earth can brute-force a strain that has no published weakness, ours included, and no ransom is ever paid or passed on through us. Ransomware falls into the forensic class of work: a free assessment first, then one fixed quote, paid upfront once you accept the fixed quote.

// before you post it

Sending it in — remove the drive if you can

Before anything is posted, unplug the network leads and leave the affected machines alone: no antivirus scans, no reinstalling and no formatting, because each of these wears away the remnants that recovery depends on. Save the ransom note and a couple of encrypted sample files so the strain can be identified, then phone 0800 689 0668 for a quote first and to agree what should be sent. Capture is done on the isolated bench, and recovery only ever works on the copies.

// getting your device to us

Post or courier your device — it's simple

Most customers get a quote first, by phone or with the free online diagnostic, and then post or courier their media to us.

Sending a drive from a computer, laptop, MacBook, iMac, CCTV / DVR or server? Please remove the internal hard drive or SSD and send us just the drive (from a server, every disk, each labelled with its bay), as we don't offer a drive-removal service. We don't recover storage soldered to a motherboard (for example T2 and Apple Silicon Macs and some thin laptops), only drives that can be removed and sent to us. If you're not sure which kind you have, ring us first.

  • Wrap the device in bubble wrap or a padded envelope. An external drive goes whole, in its enclosure with its cable and power supply; bare drives and cards don't need cables.
  • Print and enclose the booking-in & shipping form (PDF) with your name, phone number and a short description of what happened.
  • Get a quote first, by phone or with the free online diagnostic, then post it by Royal Mail Special Delivery or any tracked courier you book yourself, for full insurance in transit.
  • Would you rather hand it over in person? Once you have a quote, you can drop it in at the Oxford lab's reception at the address shown, Monday to Friday, 9am to 5:30pm, no appointment needed.

// ransomware recovery questions

Common questions

Only where the strain allows it: a free decryptor has already been published, or a flaw is already documented, which covers a minority of families (some older STOP/Djvu variants, for example). Sound encryption stays locked to everyone, so the effort shifts to snapshots, backups, deleted originals, carved fragments and rebuilt volumes instead. The assessment tells you which side of that line you're on.
Never, however it's framed. We won't pay, won't act as a go-between and won't recommend paying: it funds crime, promises nothing, and the criminals' own tools regularly corrupt the files they unlock. That decision rests with you, your insurer and your advisers; our job is to recover everything that can be recovered without them.
The drives are assessed free of charge, with the assessment completed within 2 working days of arrival, followed by one fixed written quote. Ransomware falls into the forensic class of work, so it is paid upfront once you accept the fixed quote, before recovery begins, and that quote sets out the realistic scope before you part with anything.
Pull the network cables from everything affected and change nothing else: no reinstalls, no formatting and no clean-up utilities, because each of these wears away the remnants that recovery relies on. Keep the ransom note and a couple of encrypted sample files so the strain can be identified, ring 0800 689 0668 for a quote first, then post the drives, labelled by bay (or the NAS itself if they will not come out), tracked and insured to our Oxford lab. Every step is carried out on forensic images, and your originals stay sealed.
There are fewer firms doing this than the search results suggest, and much of what's advertised is resold negotiation. Swindon Data Recovery runs the work in-house: drives from encrypted PCs, NAS units, servers and virtual estates arrive at our Oxford lab by tracked post or courier from all over the UK, Monday to Friday, 9am to 5:30pm. Our free assessment names your strain and the realistic routes open to you; as this is classed as forensic work, the quote is paid upfront once you accept it, and we never pay or broker a ransom.
