A ransomware simulation drill tests whether your staff freeze, forward the ransom note to three people, or follow the plan when a fake attacker starts locking down files — and in 2026, most Australian businesses still find out the answer during a real incident instead of a rehearsed one.
TL;DR
- Run a ransomware simulation drill for staff within 90 days — untested incident response plans fail when it counts.
- Get executive sign-off before the trigger event, or the drill gets mistaken for a real breach.
- Score detection and reporting time, not just who clicked — ransomware spreads after the click.
- Debrief within 48 hours; lessons fade fast without a fast recap.
- Quarterly cadence beats a once-a-year drill for building real muscle memory.
Why this matters
A phishing simulation tells you who clicks a bad link. A ransomware simulation drill tells you what happens next — whether the person who clicked reports it in five minutes or sits on it for two days while a fake payload spreads across the network. That gap is where real ransomware incidents turn from a contained event into a company-wide shutdown.
Most security awareness programs stop at click-rate reporting. If your organisation has never run a full ransomware simulation, you don't actually know your mean time to report, and you don't know whether IT and frontline staff will coordinate under pressure. Training staff to recognise cyber security threats builds the baseline; a simulation drill tests whether that training holds up when the scenario feels real.
Ransomware in 2026 rarely arrives as an obvious executable. It shows up as a fake invoice, a compromised vendor login, or a lookalike login page that harvests credentials before the encryption stage even starts. A drill built around a single obvious "you've been hacked" screen misses that entire attack chain.
What you'll need
- A defined attack scenario with 2-3 realistic entry points (phishing email, fake software update, compromised shared drive link)
- A sandboxed test environment or a small group of decoy machines — never run detonation on production systems
- A fake lock-screen or ransom-note template that looks credible but is clearly logged as a drill in your systems
- IT and helpdesk staff briefed and on standby, but not the general staff population
- An incident response runbook to measure staff actions against
- A scoring rubric covering detection time, reporting time, and escalation accuracy
- Executive and legal sign-off in writing before the trigger date
The steps
1. Get executive sign-off and put it in writing
A ransomware simulation drill without leadership sign-off is a liability, not a training exercise. Executives need to approve the scenario, the timing, and the fact that some staff will genuinely believe systems are down. Put the sign-off in an email thread, not a verbal nod — if a manager escalates the "incident" to the board mid-drill, you need proof this was authorised. Skipping this step is the single most common reason drills get shut down halfway through.
2. Define the scenario and the inject points
Pick one realistic entry vector per drill rather than five at once — a compromised vendor invoice email is more useful than a generic "ransomware is here" popup. Build in 2-3 inject points across the simulated timeline: the initial email, a fake internal alert 20 minutes later, and a simulated "files are encrypting" notification at the 45-minute mark. This staged approach mirrors how ransomware actually unfolds and tests whether staff report early or wait for confirmation.
3. Build the detonation trigger
Use a fake lock-screen or a decoy file set that renames itself with a ransomware-style extension on a small number of sandboxed test machines only. The trigger should look convincing enough to create urgency but must log clearly as a drill in your endpoint monitoring so it never gets escalated to a real breach response team by mistake. Test the trigger on one machine first — a broken detonation script undermines the entire exercise.
4. Brief IT and helpdesk, not frontline staff
Your helpdesk and IT security team need to know the exact date, time, and scope so they can distinguish the drill from a real incident on their monitoring dashboards. General staff should not know the date — surprise is what you're measuring. Running stealth phishing simulations without alerts covers the same principle for phishing campaigns and applies directly here: tip off too many people and the data is worthless.
5. Run the drill and time every response
Launch the scenario and start a stopwatch on two numbers: time to first report, and time to escalation past the initial reporter. In 2026, a strong benchmark is under 10 minutes to first report and under 30 minutes to full IT escalation for a mid-sized team. Anything past 60 minutes on either metric signals a gap in either awareness or your reporting process, not just staff attentiveness.
6. Score against the runbook, not just outcomes
Compare what staff actually did against your written incident response runbook line by line — did they unplug the machine, did they email IT instead of calling, did they warn colleagues before reporting officially. A drill that only tracks "did they click" misses the entire back half of the incident, which is where ransomware actually does its damage.
7. Debrief within 48 hours
Hold the debrief within two days while memory of the drill is still sharp. Cover what worked, where the runbook broke down, and what staff misunderstood about the escalation path. Communicating a data breach to non-technical staff is the right template for framing this debrief in plain language rather than security jargon that half the room tunes out.
8. Feed findings back into training and policy
Update your onboarding materials, your escalation policy, and your next simulation scenario based on what broke this time. A drill that produces a report nobody reads is a wasted exercise — the value sits entirely in the fixes that follow.

Troubleshooting
- Staff panic and mass-forward the alert. Set clear reporting instructions in the initial security awareness onboarding — one designated contact, not a reply-all thread. Rerun the same scenario in 90 days to check if the fix worked.
- IT disables the fake payload before the timer runs. Brief IT to let the drill run its full duration unless a genuine safety issue appears; cutting it short means you never measure the full response chain.
- Nobody reports anything at all. This is your worst-case finding and the most valuable one — it means your reporting channel is unknown or distrusted, not that staff are careless. Designing an escalation path for repeat clickers gives a structure to fix this before your next drill.
- Executives push back on running it again. Bring the timed metrics from the last drill to the conversation — a 45-minute escalation gap is a harder argument to dismiss than a general request for "more training."
- Remote staff miss the drill entirely. Stagger the trigger across time zones or run a second wave a week later specifically for remote and distributed employees so the sample isn't skewed toward the office.
- The drill gets mistaken for a real breach. This happens when IT wasn't briefed properly in step 4 — always confirm the on-call security contact has the exact trigger time in writing before launch.
Tools and resources
- A written incident response runbook staff can be scored against
- A scoring rubric covering detection time, reporting time, and escalation accuracy
- Cyber security training for new employee onboarding to make sure new hires aren't drilled before they've had baseline training
- A debrief template that avoids technical jargon for non-security staff
- A quarterly drill calendar so the exercise doesn't slip to "whenever we remember"
What to do next
Once the first ransomware simulation drill is scored and debriefed, the next move is proving the value upward. Briefing executives on security awareness outcomes turns your timed metrics into a report leadership will actually read and fund the next round for.
FAQ
What is a ransomware simulation drill for staff?
It's a controlled exercise that mimics a ransomware attack — a fake phishing email, a decoy lock-screen, or a simulated file-encryption alert — to test how staff detect, report, and escalate the incident. Unlike a phishing simulation, it measures the full response chain, not just the click.
How often should you run a ransomware simulation drill?
Quarterly drills in 2026 build stronger response habits than a single annual exercise. Repetition is what fixes reporting delays, not one big event staff forget within a month.
Is a ransomware drill different from a phishing simulation?
Yes — a phishing simulation measures click rates on a fake email, while a ransomware drill extends the scenario to test detection, reporting speed, and IT escalation after the initial compromise. Most organisations run phishing simulations but skip the ransomware follow-through entirely.
Who should be told about the drill in advance?
Only IT, helpdesk, and the executive sponsor need advance notice of the exact date and scenario. General staff should not know in advance, or the drill stops measuring real behaviour.
What's a good response time benchmark for a ransomware drill?
Under 10 minutes to first report and under 30 minutes to full IT escalation is a strong benchmark for a mid-sized team in 2026. Times beyond 60 minutes on either metric point to a gap in awareness or reporting process.
Can a ransomware drill be run on production systems?
No — detonation should always happen on sandboxed or decoy machines, never production systems, to avoid real data loss or downtime. The scenario should look real to staff without any actual risk to live infrastructure.
How do you score a ransomware simulation drill?
Score against your written incident response runbook: time to detection, time to report, and whether escalation followed the correct chain rather than informal channels. Click rate alone is not a sufficient score for a ransomware-specific drill.
What happens if staff fail the drill badly?
A poor result is the reason to run the drill, not a reason to cancel the program — it identifies exactly where the runbook or training needs revision before a real incident exposes the same gap. Rerun a modified version of the same scenario within 90 days to confirm the fix worked.
One last thing
The most useful number from a ransomware simulation drill is never the click rate — it's the gap between when someone noticed something wrong and when they actually told IT. Most organisations that measure this for the first time in 2026 find that gap sits closer to an hour than the 10 minutes they assumed, and that single number is usually enough to get budget approved for the next drill.
