The package '@shikijs/langs' version 3.22.0 has multiple YARA rule matches related to 'wordpress_xmlrpc' in 'blade.mjs', 'hack.mjs', and 'php.mjs'. The 'powershell.mjs' file also triggered the 'pshome_casing' YARA rule. While these matches suggest potential suspicious behavior, they are not strong enough to classify the package as malware, especially considering the absence of known false positives or legitimate use cases. The 'wordpress_xmlrpc' rule may be triggered due to the package's language support capabilities, and 'pshome_casing' might be related to how the package handles PowerShell syntax highlighting or code analysis. Without further evidence, it's safer to assume these are coincidental matches or part of the package's normal functionality.
