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
Built on a family legacy of proud steamfitters dating back to over 100 years, Heritage Mechanical was established in 2012 to provide quality mechanical service to the commercial construction industry. Opening its doors with only three employees and a master plan, the company has since grown rapidly to become one of the fastest growing mechanical construction firms serving the DMV.
