RANSOMWARE ATTACK SIMULATIONS

Ransomware simulation: see if you survive the attack before it really comes

We safely replay the full ransomware scenario: from entry through lateral movement to an encryption attempt, without destroying data. You test your backups, EDR, segmentation and the team’s real response time.

WHY IT MATTERS

A backup nobody has tested under pressure is an assumption, not a control

Ransomware is today the most common cause of costly downtime. Most companies assume they have backups and that they will work. A simulation tests that assumption before a real attack does.

We replay the attack chain the way ransomware groups do: we get in, escalate privileges, hunt for backups and critical systems, and finally run a harmless equivalent of encryption. All to measure whether and when someone stops it.

WHAT WE DO

The full scenario, with no real damage

01
Entry and escalation
We gain a foothold and raise privileges, just like a real ransomware group.
02
Backup hunting
We check whether the attacker reaches your backups and whether they are isolated.
03
Encryption test
We run a harmless encryption equivalent to measure detection and response.
04
Recovery assessment
We verify whether and how quickly you can recover critical systems.

No real data is encrypted or destroyed. We define scope and markers before we start.

OUR APPROACH

A real scenario, zero real loss

The value of a ransomware simulation lies in the realism of the attack chain, not in destroying data. We replay every stage but replace encryption with a safe marker that lets us measure impact without risk.

The most important questions are not about encryption itself but what precedes it: did the attacker reach the backups, did segmentation stop them, how fast did the team notice. We answer those with evidence.

COMPLIANCE

Proof of readiness for the most common crisis scenario

Testing ransomware resilience maps to regulatory requirements on business continuity and incident response.

NIS2
Evidence of the ability to detect, respond and maintain continuity.
DORA
Validation of operational resilience and post-incident recovery plans.
ISO 27001
Confirmation that backups and response processes are effective.

STANDARDS & CERTIFICATIONS

We work to recognized methodologies, not gut feeling

Every project is run by certified pentesters and based on public standards. That makes the result repeatable, auditable and comparable across vendors.

HOW WE DO IT

A scenario run in stages

01
Scoping
We define scope, markers and boundaries before we start.
02
Entry
We gain a foothold via a realistic route.
03
Movement and escalation
We raise privileges and hunt for critical systems and backups.
04
Encryption test
We run a safe marker and measure the response.
05
Report
We document the timeline, gaps and continuity recommendations.

EVIDENCE

Numbers behind every promise

Every test is run by certified pentesters, and we document the result with reproduction steps, evidence and a verified remediation path. Proof, not a promise.

After fixes are deployed we confirm in writing that the gaps are closed. We do not vanish once the PDF is sent.

KNOWLEDGE

Ransomware attack simulation in practice

What a controlled ransomware simulation is

A ransomware simulation reproduces the full course of a real attack, from initial access to the moment an attacker would be ready to encrypt the data. We do it in a controlled way, without destroying files and without risk to business continuity.

The goal is not to prove that ransomware works, because that is known. The goal is to check whether your company stops such an attack before it reaches the encryption stage.

How we reproduce a ransomware attack

We recreate the typical chain: gaining access, privilege escalation, lateral movement and preparation for mass encryption and data exfiltration. We map every stage to MITRE ATT&CK and document it with evidence.

We stop just before causing real damage, but after passing through all the steps that lead to it. This way you know how far an attacker would get and at which point they could be stopped.

What we check: whether you stop the attack in time

We check three things that really decide survival of an attack: whether you detect it, whether segmentation limits its spread and whether your backups truly allow recovery. That is far more than a list of vulnerabilities.

It often turns out that backups exist but are reachable from the same network the attacker already controls. We surface such gaps before a real attack exploits them.

What you get and when to do it

The report describes the course of the simulation, the detection points, weak spots in segmentation and backups, and a concrete strengthening plan. We add a business summary with a realistic loss scenario.

A ransomware simulation is worth running if you are concerned about this class of attack or want to verify a continuity plan in practice, not just on paper. It is one of the best tests of readiness for a real crisis.

FAQ

Common questions

Do you encrypt our data?

No. Instead of real encryption we use a harmless marker that lets us measure detection and response with no damage to data.

What does the simulation test besides encryption?

Above all what precedes it: the entry route, escalation, access to backups, segmentation and the team’s time to detect and respond.

Is it safe for production?

Yes. Risky actions are agreed in advance and run in a controlled way, with no data destruction and no real downtime.

Do you also test recovery from backups?

Yes, on request we verify the real recovery process for critical systems and measure how long it actually takes.
