About KillerScan

Open-source network scanner for Windows with device discovery, port scanning, service identification and live monitoring.

What's new in 1.8.3

Changed
- Refreshed the bundled MAC vendor database to 58,575 assignments.
- Scan History and Scan Profiles open wide enough to show every date in full. Dragging the sidebar narrower draws their text up to 15% smaller before it is cut off.
Fixed
- The theme and language menus open beside their own rail buttons instead of at the corner of the device list.
- A thin black line no longer shows under the title bar. The film grain now covers the whole bar.
- The dot in a selected radio button sits in the middle of its ring, and radio buttons and checkboxes line up with the capitals of their labels in Killer Sans UI and on 98SE.
