Ransomware Recovery & Decryption

Encrypted does not
always mean lost.

A-Lab investigates ransomware incidents and recovers data from encrypted databases, backups, virtual machines and enterprise storage. We analyse how the ransomware works, find its weakness and rebuild your data. There is no need to contact the attackers.

Ransomware incident

Immediate actions after a ransomware attack

The first hour decides how much data comes back. Most of it is about what not to do.

Full first-hour checklist

Isolate, do not power off

Unplug the network cable or disable Wi-Fi on affected systems. Do not reboot, format or reinstall. Memory and disks hold the evidence that makes recovery possible.

Keep the note and the encrypted files

Do not rename files, delete the ransom note or remove encrypted backups. Do not run decryptor tools found online. Identification must come first.

Send samples to start incident response

The ransom note plus two or three encrypted files on WhatsApp. Within hours you know the family, what is recoverable and the fixed price. No need to contact the attackers.

Plain-language explainer

What actually happens in a ransomware attack

Ransomware is malicious software that encrypts your files so they cannot be opened, then demands payment for the key. Modern groups also steal your data first and threaten to publish it. The attack is rarely a single event. It is a chain of steps that can run for days or weeks before the encryption you finally see.

Laboratory services

Post-ransomware recovery, end to end

From the first hour of the incident to verified, working data. Every engagement starts with a free assessment and a fixed quotation.

Incident response

We identify the ransomware family from the ransom note and encrypted samples, establish what is recoverable and give you a clear plan within hours.

  • Strain identification
  • Recoverability report
  • Fixed quotation, no obligation

Data decryption

We study the encryption implementation, locate flaws such as weak key generation or partial encryption, and build tools that restore your files without the attackers' key.

  • Documents, archives, mail stores
  • PCs, servers, NAS and RAID
  • Folder structure preserved

Forensic storage recovery

When files were deleted, overwritten or damaged during the attack, our laboratory recovers them from the underlying storage using forensic techniques.

  • Deleted and shadow-copy data
  • SAN, NAS and RAID arrays
  • Physical and logical damage

Database repair

Encrypted or corrupted databases are reconstructed page by page so ERP, accounting and CRM systems run again with your real records.

  • Microsoft SQL, MySQL, PostgreSQL, Oracle
  • Partially encrypted MDF / IBD / DBF files
  • Integrity verification after repair

Virtual machine restoration

Hypervisors are the primary target of modern ransomware. We decrypt and rebuild virtual disks so whole environments return to service.

  • VMware ESXi (VMDK), Hyper-V (VHDX)
  • Proxmox, KVM, Citrix, Nutanix
  • Boot-ready machines delivered

Backup recovery

Backups are usually encrypted first. We repair Veeam VBK/VIB chains, Windows Server Backup, Acronis and tape images so restore points become usable again.

  • Veeam, Acronis, Commvault formats
  • Damaged backup catalogues
  • Tape and LTO media
Environments

What we recover after a ransomware attack

Ransomware rarely stops at documents. These are the systems that arrive in the laboratory most often.

File servers and NAS

Windows file servers, Synology, QNAP and NetApp. Encrypted shares, snapshots and RAID arrays.

Virtual machines

VMware ESXi, Hyper-V, Proxmox, Nutanix. Encrypted VMDK and VHDX disks rebuilt to a bootable state.

Databases

Microsoft SQL Server, MySQL, PostgreSQL, Oracle. Page-level repair of the data files behind ERP, accounting and CRM.

Backups

Veeam, Acronis, Commvault, Windows Server Backup, NAS snapshots and tape. Encrypted backup chains reconstructed.

Mail and collaboration

Exchange databases, Outlook PST archives, SharePoint and document management systems.

Workstations

PCs, laptops and external drives hit by STOP/Djvu, Phobos, Dharma and other small-business strains.

Our approach

Every ransomware leaves clues. We find the weakness and use it.

Ransomware is software written under pressure by criminals. It contains mistakes: weak random-number generation, reused keys, partial encryption of large files, traces left in memory and on disk. Our engineers study the exact build that hit you and turn those mistakes into a recovery method. When no public decryptor exists, we develop our own.

This is a forensic engineering problem, not a negotiation. It is why there is no need to contact the attackers.

Before you pay

Why contacting the attackers is the weakest option

Paying a ransom is a transaction with an anonymous criminal group. It is not a recovery plan. Public research on UAE organisations shows that most companies which paid were attacked again, often within a month, and with a higher demand.

  • No guarantee that a working decryptor is delivered
  • Decryptors supplied by attackers are often slow, buggy and corrupt large files
  • Stolen data is frequently leaked or sold regardless of payment
  • Payment marks you as a proven, paying target
  • Regulatory and sanctions exposure for the payer

Contacting the attackers

  • Negotiation with criminals
  • Payment first, results unknown
  • Attacker tool may fail on databases and VMs
  • Data still in criminal hands
  • Repeat attacks are common

A-Lab forensic recovery

  • No contact with the attackers
  • Verify recovered data first, pay after
  • Purpose-built tools per case
  • Clean, verified delivery media
  • Entry-point report to prevent repeat

FAQ

Ransomware recovery questions

In most cases, yes. Recovery comes from weaknesses in the ransomware's encryption, from the internal structure of large files such as databases, virtual disks and backups that are only partially encrypted, and from storage-level recovery of data the attackers deleted. The free assessment tells you which route applies to your case before you decide anything.

The ransom note, two or three encrypted files of different types and sizes, the encrypted extension, and a short description of the environment. Send it on WhatsApp.

Assessment takes a few hours. Recovery ranges from one to two days for a small office to a week or more for large virtualised environments. Critical systems are prioritised so the business can restart first.

No. Payment does not guarantee a working decryptor, attacker tools often corrupt large files, stolen data is frequently leaked anyway, and paid victims are attacked again. Obtain a recovery assessment before any decision about payment.

Usually not. Backup containers are large and modern ransomware encrypts only parts of large files, so Veeam chains, VHDX files and SQL dumps are frequently rebuilt. Do not delete them.

The assessment is free. A fixed quotation follows, based on the family, the volume of data and the systems involved. Payment is made only after you have verified the recovered data. No recovery, no fee.

Work happens on isolated laboratory systems. An NDA is signed on request and working copies are wiped after you confirm delivery. Consultancies and MSPs can engage us on behalf of clients confidentially.
