  • This release adds a credential-free scan to remotely check for the Microsoft MS17-010 (WannaCrypt, WannaCryptor, WannaCry) vulnerability and indicates whether the patch has been applied. This is a follow-up to our May 15th release showing full SMB enabled status and is arguably a much more important feature.

New in Slitheris Network Discovery 1.1.219 (May 16, 2017)

  • Added an SMBv1/v2 detection feature to help our users individually discover whether SMBv1 or SMBv1 exists on PCs, servers or other devices that use SMB. allows IT security professionals to perform a remote credential-less check for SMBv1 existence when choosing to disable the deprecated SMBv1 protocol. Users may wish to do this as an extra precaution due to the historic May 2017 ransomware known as WannaCryptor (aka WannaCry). It can also be used to verify SMBv2 exists on NAS’s or other specialized network devices prior to performing removal of SMBv1 on various Windows systems.
