Collection

Once attackers complete discovery and understand the environment, their next step is to gather the data they want to steal.

This phase is called collection.

Collection is when attackers locate, stage, and prepare sensitive information for theft — often quietly and over time.

Think of it like a burglar who:

finds the file cabinets
opens drawers one by one
stacks valuables neatly
and prepares everything for a quick exit

They’re not stealing yet.
They’re organizing what they plan to steal.

Digitally, attackers perform collection by:

searching shared drives for sensitive files
locating databases and backups
copying documents into staging folders
compressing large data sets
scraping email inboxes
gathering credentials or tokens
preparing archives for data exfiltration

Why this matters for insurance:
Collection is the quiet stage before the breach becomes public.
It’s where attackers gather:

customer data
financial records
intellectual property
employee information
authentication secrets

If a company lacks internal visibility — especially through EDR, SIEM, or a well‑run SOC — collection often goes completely unnoticed.

And once data is collected, exfiltration is only a step away.

When a company says, “We don’t think any data was taken,” the real question is:

“Did the attacker collect anything — and would you have seen it if they did?”

The takeaway:
Collection is the staging phase before data theft.
If you detect it early, you can prevent a breach from escalating into regulatory, legal, and reputational fallout.

Pop Culture Parallel:
In The Italian Job, the crew spends significant time gathering and organizing the gold before making their escape. Collection works the same way in cyber incidents — preparation before the exit.

Real‑World Example:
During the 2020 SolarWinds attack, threat actors quietly collected emails and documents from targeted organizations for months before exfiltrating them — demonstrating how long collection can occur before anyone notices.
