ClipboardShield – A Clipboard Firewall for Windows (FOSS)
I’d like to introduce ClipboardShield [1], a free open-source clipboard firewall for Windows 10/11. It helps protect against clipboard hijacking attacks [2], where malicious apps silently read or modify clipboard contents (e.g., replacing copied cryptocurrency addresses to modify the recipient and steal user’s funds or stealing sensitive data like passwords). How it works: - Define rules to allow or block clipboard access for specific apps. - Prevent unauthorized apps from reading or modifying clipboard contents. - Open-source and community-driven – contributions are welcome! - Since…
What it does
In the maker’s words, at launch
I’d like to introduce ClipboardShield [1], a free open-source clipboard firewall for Windows 10/11. It helps protect against clipboard hijacking attacks [2], where malicious apps silently read or modify clipboard contents (e.g., replacing copied cryptocurrency addresses to modify the recipient and steal user’s funds or stealing sensitive data like passwords). How it works: - Define rules to allow or block clipboard access for specific apps. - Prevent unauthorized apps from reading or modifying clipboard contents. - Open-source and community-driven – contributions are welcome! - Since many people copy and paste passwords, crypto addresses, and other sensitive data, ClipboardShield adds an extra layer of security by letting you control which applications can access the clipboard. Get Started: - GitHub repository: <https://github.com/CoinFabrik/ClipboardShield> - Quickstart guide: <https://github.com/CoinFabrik/ClipboardShield/blob/master/RE...> - First release (includes source code and binary installer): <https://github.com/CoinFabrik/ClipboardShield/releases/tag/2...> ClipboardShield uses a system-level hooking engine to manage clipboard access without interfering with normal usage [3].

We are longtime members of HN and this is our only submission requesting feedback from the HN community on our product, Clipboard which we have been developing for the past year. Clipboard is a service to save anything online using a bookmarklet or browser extension (think Dropbox for content on the web). Clipboard is built using open source technologies, including Riak, Redis, NGINX, Node.js, and jQuery. One of our core differentiators is how we preserve the visual look and functionality of the original source, which is evident in the sample clips from github here:…

- IMI made my commercial clipboard manager open source because it's right2025 · ▲6
Hey HN, Clipboard managers handle sensitive data such as passwords, personal notes, API keys, etc. To trust one you need to be sure that it doesn't send your data to third parties or store it on remote servers. With closed-source apps, you have to take the developer’s word for it. As a software engineer, I don't like that. Transparency matters. So, I decided to make my commercial clipboard manager open source. Anyone can inspect the source code, verify that data stays local and never leaves the user's device. Anyone can build the app from source and use it. At the same time, the app is still…
