+Yesterday [a GitHub issue about mismatching hashes coming from this website](https://github.com/monero-project/monero/issues/6151) was opened. A quick investigation found that the binaries of the CLI wallet had been compromised and a malicious version was being served. The problem was immediately fixed, which means the compromised files were online for a very short amount of time. The binaries are now served from another, safe, source. [See the reddit post by core team member binaryfate](https://www.reddit.com/r/Monero/comments/dyfozs/security_warning_cli_binaries_available_on/).
+
+It's strongly recommended to anyone who downloaded the CLI wallet from this website between Monday 18th 2:30 AM UTC and 4:30 PM UTC, to check the hashes of their binaries. If they don't match the official ones, delete the files and download them again. Do not run the compromised binaries for any reason.
+
+We have two guides available to help users check the authenticity of their binaries: Verify binaries on Windows (beginner) and Verify binaries on Linux, Mac, or Windows command line (advanced). Signed hashes can be found here: https://getmonero.org/downloads/hashes.txt.
+
+The situation is being investigated and updates will be provided soon.
