Dear All,

1.Will I used same patch MS17-010 for both attacks at user end?

2.What is the difference BTW these two attacks?

3.Will I disable SMBv1?

Re: NETBIOS-SS: Windows SMB Remote Code Execution Vulnerability

@User27622125 

A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server. To exploit the vulnerability, in most situations, an authenticated attacker could send a specially crafted packet to a targeted SMBv1 server. The security update addresses the vulnerability by correcting how SMBv1 handles these specially crafted requests.

 

Yes,  you may plan to disable SMB v1 as prevention measures.

Hi @User27622125 

May I know which signature you are referring that defines implant tool and remote cote execution?

In general, implant tools are used to install the application that could be used for remote code execution. While the execution is launching a malicious activity with the tool installaed.
