Alternate Data Streams (ADS) are a feature in NTFS which are often seen as a liability in infosec circles. They have been used to obscure malware and rootkits, making it difficult to detect their presence. However, these same qualities that make ADS attractive to malware developers also makes ADS an interesting avenue for securing critical data. In this talk I'll demonstrate the initial release of ShaDOS, a PowerShell module that can create a secret file system inside of a Windows installation. This can both keep information safe from unauthorized access and prevent data exfiltration.
