Compromised Plugins: This Is What’s Going On

A supply chain attack is a sophisticated form of cyberattack where hackers infiltrate a system by compromising a trusted third-party source, such as a software vendor. In this case, the attackers targeted the source code of popular WordPress plugins, embedding malicious code that could execute on any site using the compromised plugin. This method allows hackers to bypass traditional security measures, as the compromised plugins are seen as legitimate updates by WordPress sites.

The primary issue lies in the fact that these compromised plugins have been distributed through official channels, making it difficult for users to identify the malicious versions. The attack not only affects the security of websites but also poses a significant threat to user data and privacy.
