Log4j Proved Public Disclosure Still Helps Attackers

A tweet on December 9, 2021, disclosed a zero-day proof-of-concept (PoC) exploit for the vulnerability known as Log4Shell, sparking panic and rapid mitigation efforts. The article emphasizes that public disclosure of vulnerabilities, particularly without vendor patches, only aids threat actors. It argues for a more robust and coordinated disclosure process, such as the vendor-first approach utilized by Google and Microsoft, that keeps PoCs confidential until a vendor patch is available.
