Over 70% of all known WordPress vulnerabilities were originally published by Patchstack in 2023 and hundreds of popular plugins such as Elementor, RankMath and WProcket have set Patchstack as their official security partner.
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.
