The DOUBLEPULSAR backdoor is detected on the remote Windows host.
PVS 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.
Remove the Double Pulsar backdoor and disable SMBv1.
