It starts like any other morning — except for the IT admin, who logs in first.
You check the monitoring dashboard and see a few alerts: elevated CPU usage, a couple of failed logins, then a string of disconnected endpoints. At first, it looks like routine noise. Maybe a patch failed overnight. Maybe a script hung.
But then you try to remote into a system and get no response. You check the file servers: shared drives are inaccessible and offline. Support tickets start pouring in. Files won’t open. Apps are crashing. Then a user sends a screenshot:
Coveware by Veeam Insight: These messages are designed to create pressure. But the worst outcomes usually happen when organizations rush into decisions before assessing their options.
This is what ransomware looks like in real time.
It doesn’t arrive with a loud warning. It unfolds quietly, spreads fast, and can take an entire organization offline before most people realize what’s happening.
At Coveware by Veeam, we’ve seen this play out thousands of times. Here’s what the first moments of an attack really feel like, from the inside out.
The Calm Before the Storm
The first signs are subtle: a lagging system, a file that won’t save, a shared folder gone missing. Antivirus crashes and restarts. On the surface, it looks like routine IT noise.
But under the hood, ransomware executables are already running, silently encrypting systems. Most launches are timed for overnight or early morning hours to avoid detection. By the time the workday begins, the damage is already well underway.
Coveware by Veeam Insight: One of the most common mistakes is assuming early symptoms are isolated glitches. That assumption often costs the organization its containment window.
Encryption Hits the Core
This isn’t about a single user’s laptop. Encryption malware goes after your core infrastructure: shared files, databases, authentication systems, even backups.
Files become unreadable or disappear entirely. Applications crash because dependencies are corrupted. Cloud sync tools replicate encrypted versions. Systems that once worked together start failing in unison.
Coveware by Veeam Insight: In many incidents, the full scope isn’t understood until multiple systems fail in ways that seem unrelated, until someone connects the dots.
Operations Grind to a Halt
As encryption spreads, business stops.
File shares go dark. CRMs and ERPs won’t load. Communication platforms break down. Authentication systems collapse. Business units can’t function because the systems they rely on no longer exist.
In manufacturing, lines stop. In healthcare, care is delayed. In finance, trades stall and compliance systems fail.
Coveware by Veeam Insight: Most organizations don’t realize how interconnected their systems are until one attack takes them all down at once.
First-Hour Missteps Make Things Worse
Panic as fast as the malware. Users reboot machines or unplug them from the network. IT starts restoring from backups without confirming the threat is contained. Security isn’t looped in quickly enough.
Evidence gets wiped. Recovery paths get corrupted. Scope becomes impossible to define.
Coveware by Veeam Insight: Teams that have trained and tested their playbooks respond with clarity. The first hour is when discipline matters most.
Panic, Confusion, and the Communication Breakdown
With internal systems offline, communication breaks down. Email, chat, and ticketing are gone. People turn to phones or personal devices. Rumors take over.
“Is this just IT?”
“Is this a nation-state?”
“Should we call legal?”
Executives get partial information. Security teams are overwhelmed. Coordination collapses.
Coveware by Veeam Insight: Chaos is normal in the early minutes of an incident. but strong crisis communication plans and clearly defined roles reduce confusion and restore order faster.
Key Takeaways from the Front Lines
After supporting thousands of ransomware cases, here’s what we’ve seen again and again:
- Encryption is fast. You won’t have hours to figure it out.
- User behavior matters. A single misstep can complicate response and recovery.
- Playbooks must be tested. Plans that only exist on paper don’t hold up under real pressure.
The organizations that recover fastest aren’t the ones with the biggest budgets. They’re the ones that prepared.
Final Thought
The real impact of ransomware isn’t just encrypted files; it’s the loss of control, visibility, and coordination across your entire business.
No one is immune, and no one responds perfectly. But preparation through training, real-world exercises, and hard-won lessons makes the difference between a controlled incident and a prolonged crisis.
In the first hour, what you do matters. After that, it’s about how well you’ve planned.
