Window Zero
EXPOSURE GAP
Window Zero is the time the breach stayed in the open before
anyone said so — the gap between when the attack was first discovered
on the operator's leak site (t1) and when it was publicly disclosed (t2).
The wider this window, the longer victims, staff and customers were exposed with no warning.

Attack Summary
In the early 1970s, MMWEC worked to gather and focus the collective strength of municipal utilities on issues and developments that were threatening the viability of public power in Massachusetts. Joint action led to the acceptance of municipal utilities into the New England Power Pool in 1973, giving municipals the right to joint ownership in the large, regional power plants under development by private utilities.
