Factoring "short-sleeve" RSA keys with polynomials

https://blog.trailofbits.com/2026/06/12/factoring-short-sleeve-rsa-keys-with-polynomials/shortsleevekeys_figure1_hu_49c6698c7e83848f.webp
Researchers discovered hundreds of unique RSA and DSA keys generated by the CompleteFTP software that were vulnerable to factorization due to a bug causing biased bits towards 0. The bug was fixed in 2019, but the researchers found that the proportion of affected keys has plateaued, indicating that many users still have vulnerable keys that need to be regenerated.

How memory safety CVEs differ between Rust and C/C++

Rust's memory safety is more effective in practice than C or C++ because it treats potential vulnerabilities as library bugs, not user code bugs, unless the user explicitly uses the unsafe keyword. This approach allows Rust to scale in practice by automatically ensuring memory safety in safe Rust code, whereas C or C++ libraries can still be misused to introduce memory unsafety.
