This week's leaks came out of an airline, big-box retail, the European Union, a website-building company, the auto industry, and South Korea's foreign ministry. These were mostly internal documents, and several surfaced before the organization had said anything publicly:
- Southwest Airlines' 737 MAX 7 rollout plan leaked

November 4, 2026
A file containing personal details of the presidential delegation turned up on a malware-scanning website, and the ministry is investigating whether someone inside the government uploaded it.
Why it matters...
Nobody has said how South Korea's presidential delegation file got out. It turned up on a website that scans files for malware, and the ministry is still investigating who put it there. The other six are easier to trace: an aircraft rollout plan handed to an aviation writer, a photo of a store notice posted on Reddit, two EU drafts that reached reporters before they were final, a layoff memo seen by a business outlet, and a photo of a planning document posted on a car blog. Whether the route ran through a reporter's inbox, a Reddit thread or a malware scanner, each document ended up somewhere it was never meant to be.
EchoMark embeds unique, invisible watermarks in documents, emails, images, and screens. When those watermarks are embedded before information goes out, they deter would-be leakers. When something does leak, investigators have the evidence to trace it back to the copy it came from.
