GhostRedirector Hits 65 Windows Servers with IIS Module

🔍 Researchers at ESET disclosed a previously undocumented campaign named GhostRedirector that has compromised at least 65 Windows servers mainly in Brazil, Thailand and Vietnam. The intruders deployed a passive C++ backdoor, Rungan, alongside a native IIS module, Gamshen, which selectively alters responses for Googlebot to perform SEO fraud. Initial access appears linked to SQL injection and abuse of xp_cmdshell, with subsequent PowerShell retrievals from a staging host.
