“We detected the payload… but the breach started three weeks earlier.”
That was the opening line in my report after investigating a ransomware incident where the encryption event was just the final act — not the breach itself.
After 20+ years in cyber threat intelligence and red teaming, I’ve learned one thing:
🔐 Ransomware is not just malware. It’s a business model. A campaign. A process.
In this article, I’ll break down:
Why most defenses detect ransomware too late
How attackers really operate
What defenders should focus on instead
💣 1. The Payload Is the Loudest — But the Last
In most of the ransomware cases I’ve worked on, the payload (the actual encryption tool) was the noisiest part of the operation.
But it wasn’t the beginning.
✅ Initial access came through:
Phishing with PowerShell macro
RDP brute force
Misconfigured VPN
The attacker lived in the system for days to weeks, often escalating privileges, mapping shares, and deploying backup scripts before launch.
🕵️ 2. Ransomware Groups Operate Like Red Teams
You’ll recognize the techniques if you’ve worked on red team or penetration test engagements:
Discovery with net view and whoami /all
Credential dumping using Mimikatz or LSASS
Lateral movement via PsExec or RDP
Scheduled tasks to persist C2 and backup toolkits
They follow MITRE ATT&CK like a playbook.
🛡️ 3. Defenders Need to Hunt Precursor Behavior
You’re not going to win by detecting ransomware binaries.
You’ll win by detecting what comes before:
Suspicious PowerShell activity in user temp folders
Unusual service installs
Remote WMI execution
SMB enumeration from user workstations
Sudden spike in internal RDP connections
These are defender gold.

“If your first alert is the ransomware payload, you’re already too late.”
