In most cases as penetration testers, if you can establish a null session to a remote server, you can query it for a ton of information including user names. Initial reports indicate the hacker or hacking group behind the WannaCry campaign is gaining access to enterprise servers either through Remote Desktop Protocol (RDP) compromise or through the exploitation of a critical Windows SMB vulnerability. An attacker who successfully exploited the vulnerabilities could gain the ability to execute code on the target server. This access permits the malware to spread itself laterally on a compromised network.

A local attacker, by sending a specially crafted IPC command, can exploit this to execute arbitrary programs with elevated privileges. A well-known vulnerability within Windows can map an anonymous connection (or null session) to a hidden share called IPC$ (which stands for interprocess communication). Since SMB provides several features such as manipulating files, shares, messaging, IPC and more, it is one of the most attractive services for hackers during enumeration and exploitation phases.
