critical Nessus Network Monitor Plugin ID 700059
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The DOUBLEPULSAR backdoor is detected on the remote Windows host.

Description

NNM detected the presence of DOUBLEPULSAR on the remote Windows host. DOUBLEPULSAR is one of multiple Equation Group SMB implants and backdoors disclosed on 2017/04/14 by a group known as the 'Shadow Brokers'. The implant allows an unauthenticated, remote attacker to use SMB as a covert channel to exfiltrate data, launch remote commands, or execute arbitrary code.

Solution

Remove the Double Pulsar backdoor and disable SMBv1.
