LiteSpeed Cache, a popular caching plugin utilized by over five million WordPress sites, is designed to enhance page load times, improve user experience, and boost search engine rankings. 

However, security experts at Automattic’s security team, WPScan, have observed a significant increase in malicious activities targeting WordPress sites with versions of the LiteSpeed Cache plugin older than 5.7.0.1.
