About this tag
The w3wp tag on WindowsForum.com covers discussions about the IIS Worker Process (w3wp.exe) in the context of security threats and vulnerabilities affecting Windows servers. Recent threads detail the GhostRedirector campaign, a sophisticated SEO fraud backdoor that compromises IIS servers by injecting malicious native modules into the w3wp process to serve altered content to search engine crawlers. Older threads reference Microsoft security bulletins for SharePoint Server, where vulnerabilities could allow remote code execution in the security context of the W3WP service account. These discussions highlight the importance of securing IIS worker processes against both modern backdoor campaigns and historical SharePoint exploits.
