Ransomware incident analysis and data recovery in Warsaw

Lost data after a ransomware attack?
Your computer, server or NAS now shows extensions such as .locked, .encrypted, .crypt or .[email], and the files will not open?

Dysk i Spółka – Data Recovery Laboratory specialises in ransomware incident analysis, safe recovery of key files and rebuilding business environments after an attack.

We work with clients across all of Poland and also accept courier shipments.

We do not promise “magic decryption”. We take a technical, honest and transparent approach.

What to do right after the attack:

do not keep restarting the server, NAS or computer without a plan
do not delete encrypted files or overwrite the affected media with new data
secure the ransom note, sample files and visible symptoms for technical analysis

Call about ransomwareReport the incident

Call us or send a short incident description. After the first contact we will tell you what to secure and what not to do.

Free standard diagnosis • initial assessment • quote after diagnosis • NDA for confidential cases

What to prepare for the first ransomware call:

the ransom note and file extension
a few encrypted sample files
whether backups still exist

Urgent case? Call immediately — we will explain what to secure first.

Why a trusted laboratory matters in this type of incident:

we assess real chances and risks honestly
we first secure the material for analysis and the environment
for confidential incidents we can work under NDA

As part of incident response, we provide:

1. Full technical analysis of the attack

identification of the ransomware family (LockBit, STOP/DJVU, Hive, BlackCat, DeadBolt and others),
analysis of extensions, ransom notes and file headers,
verification of whether public decryptors or known weaknesses exist for that malware family.

2. Assessment of real recovery options

We check:

whether the data was fully encrypted or only partially encrypted,
whether backups still exist (automatic, hidden or not deleted by the ransomware),
whether snapshots, previous versions or duplicates on other media are available,
whether part of the files remains untouched.

3. Data recovery (without misleading clients)

In practice, we recover:

unencrypted fragments (photos, videos and documents),
data from HDD / SSD / NAS devices that ransomware has only partially damaged,
files that can be reconstructed at binary level (for example damaged .docx, .xlsx, .mov),
data from memory cards and USB drives after hybrid attacks.

4. Helping businesses get back to work quickly

restoring NAS / Synology / QNAP systems after an attack,
loss analysis, post-incident report,
backup and security configuration,
guidance on whether to pay or not pay the ransom (we do not pressure anyone).

5. If decryption is possible, we do it in controlled conditions

This applies to cases where:

when public decryptors are available,
when the ransomware has known cryptographic flaws,
when the key has been recovered from a process or a copy (rare, but it happens).

What we do NOT promise (fair rules)

We do not claim that we can decrypt every ransomware case.
We do not sell “proprietary AES-256 breaking algorithms”.
We do not charge money for empty promises.
If there is no realistic chance of recovery, we say so clearly and immediately, without creating unnecessary costs.

With us, you pay only for real value and honest work.

Signs of a ransomware attack — what you see on your computer

After a ransomware attack, the same warning signs usually appear: file names change, files can no longer be opened and the system displays payment instructions. The key is not to overwrite evidence or make the situation worse.

Files have strange extensions and will not open

If documents and photos no longer work and the names/extensions have changed — do not run “repairs” and do not reinstall the system. We first secure the current state and assess the real recovery options.

A ransom note / payment message appeared in the folders

Disconnect the computer from the network (LAN / Wi‑Fi) to stop the spread. We gather information about the ransomware variant and check the available data-restoration paths.
