KnowBe4 says attackers are abusing trusted services like DocuSign, SharePoint, Adobe Sign, Dropbox and Google Drive to send phishing emails that look legitimate. In its analysis of 544,000 threat emails between June and August 2026, LOTS techniques accounted for 53,000 emails, with DocuSign and QuickBooks making up nearly two-thirds of that volume. The post says these emails can bypass security gateways because they come from real platforms. Windows users and small offices should be careful with document-share and payment messages, even when the sender looks trustworthy.
