Taint Shared Content

Adversaries may deliver payloads to remote systems by adding content to shared storage locations, such as network drives or internal code repositories. Content stored on network drives or in other shared locations may be tainted by adding malicious programs, scripts, or exploit code to otherwise valid files. Once a user opens the shared tainted content, the malicious portion can be executed to run the adversary's code on a remote system. Adversaries may use tainted shared content to move laterally. A directory share pivot is a variation on this technique that uses several other techniques to propagate malware when users access a shared network directory. It uses [Shortcut Modification](https://attack.mitre.org/techniques/T1547/009) of directory .LNK files that use [Masquerading](https://attack.mitre.org/techniques/T1036) to look like the real directories, which are hidden through [Hidden Files and Directories](https://attack.mitre.org/techniques/T1564/001). The malicious .LNK-based d
