13 Dec 2024Patchstack is one of the largest open-source vulnerability disclosers in the world. For example, in 2023 more than 70% of new WordPress vulnerabilities were originally published by Patchstack. This focus on research enables us to deploy vulnerability protection rules faster than anybody else.
Patchstack vPatching auto-mitigates security vulnerabilities even when there's no official patch available. It's the fastest and most effective way to eliminate new security vulnerabilities without sacrificing performance.
Hackers automate attacks against new security vulnerabilities to take over as many websites as they can before users have time to patch and update. The attacks are opportunistic and victims are not chosen - everyone is a target.
We recommend reaching out to your hosting provider for server-side malware scanning or use a professional incident response service. Don't rely on plugin based malware scanners as they are commonly tampered with by malware.
