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

Welcome to The Macomb Group! We’re proud to be a leading wholesale distributor of pipe, valves and fittings for the Midwest region and beyond.Founded in 1977 and acquired by the current owners in 1991, The Macomb Group has differentiated itself from competitors by continually expanding our operations to provide unbeatable specialty services, a huge inventory, energy-efficient solutions, and exceptional customer service.We pride ourselves on being a family and friend oriented business which started long before 1991. Our CEO Bill McGivern and Executive Vice President Keith Schatko first met while playing little league together. Years later, as fate would have it, both Schatko and McGivern were working at what was then known as Macomb Pipe & Supply to help pay for college tuition. Although they knew they wanted to become business owners, they also knew how important warehouse operations were to the success of a company so they learned all they could. They started by sweeping floors, packing orders, familiarizing themselves with the products and working the sales counter. When the time came, McGivern and Schatko, together with then-partner Doug Howe purchased the company.SITE: https://www.macombgroup.com Address 6600 East 15 Mile RoadSterling Heights, MI 48312Phone: (586) 274-4100Fax: (586) 274-4125
