Window Zero
EXPOSURE GAPWindow 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
sharpoffice.com.au zoominfo.com/c/sharp-office/1306869482 Sharp Office is one of Australia's longest-running B2B office suppliers — heritage dating to 1935 (John Sharp Business Systems, Sydney), merged with Stafford Menser in 2011 into Sharp Office Systems Pty Ltd, HQ in Ingleburn NSW, serving clients Australia-wide. It's a one-stop B2B platform: 25,000+ stationery SKUs, office furniture, print & copy (HP, Canon, Ricoh, Kyocera), laptops/tech, plus Managed Print Services and managed IT — "one bill, one delivery, one invoice" for businesses. Its moats: ISO 9001:2015 + EcoVadis certification, NSW government supplier status, credit accounts with 14-day terms and personal account managers. Not related to Japan's Sharp Corporation — a fully independent Australian house. Bottom line: a 90-year-old quiet institutional survivor that evolved from typewriters to managed IT, winning government and club contracts through reliability rather than flash.
