A null session is a connection with a samba or SMB server that does not require authentication with a password. In the demonstration, the user with RID 0x1f4 was enumerated regarding their password properties. Which script should be executed when the script gets closed? Wordlist dictionary. getdispname Get the privilege name Second - attacker opens a socks4 proxy on port 7777 on his local kali machine (10.0.0.5) by issuing: This means that the attacker can now use proxychains to proxy traffic from their kali box through the beacon to the target (attacker ---> beacon ---> end target). MAC Address: 00:50:56:XX:XX:XX (VMware) As with the lsaenumsid, it was possible to extract the SID but it was not possible to tell which user has that SID. Thus it might be worth a short to try to manually connect to a share. It is also possible to add and remove privileges to a specific user as well. | State: VULNERABLE # Search the file in recursive mode and download it inside /usr/share/smbmap, #Download everything to current directory, mask: specifies the mask which is used to filter the files within the directory (e.g. "" This is made from the words get domain password information. -z $2 ]; then rport=$2; else rport=139; fi, tcpdump -s0 -n -i tap0 src $rhost and port $rport -A -c 7 2>/dev/null | grep -i "samba\|s.a.m" | tr -d '.'

Are there any resources out there that go in-depth about SMB enumeration? In the demonstration, it can be observed that the current user has been allocated 35 privileges.

In our previous attempt to enumerate SID, we used the lsaenumsid command.
