The thegentlemen ransomware group listed Sharp Office on its data leak site on 2026-09-07. Country: AU Sector: Professional Services Domains named: sharpoffice.com.au, zoominfo.com Claim as published on the leak site: 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.
