The child-parent relationship here can also be depicted as client and server relation. A Little Guide to SMB Enumeration. great when smbclient doesnt work Let's see how this works by firstly updating the proxychains config file: Once proxychains are configured, the attacker can start enumerating the AD environment through the beacon like so: proxychains rpcclient 10.0.0.6 -U spotless, Victim (10.0.0.2) is enumerating DC (10.0.0.6) on behalf of attacker (10.0.0.5). rpcclient (if 111 is also open) NSE scripts. netremotetod Fetch remote time of day May need to run a second time for success. with a RID:[0x457] Hex 0x457 would = decimal. OSCP Enumeration Cheat Sheet. This means that SMB is running with NetBIOS over TCP/IP**. [DATA] 1 tasks, 1 servers, 816 login tries (l:1/p:816), ~816 tries per task How I Won 90 Days OSCP Lab Voucher for Free, https://github.com/s0wr0b1ndef/OSCP-note/, These notes are not in the context of any machines I had during the OSCP lab or exam. The name is derived from the enumeration of domain groups. . Password attack (Brute-force) Brute-force service password. querygroupmem Query group membership Nmap done: 1 IP address (1 host up) scanned in 5.58 seconds, # Requires root or enough permissions to use tcpdump, # Will listen for the first 7 packets of a null login, # Will sometimes not capture or will print multiple.

The system operates as an application-layer network protocol primarily used for offering shared access to files, printers, serial ports, and other sorts of communications between nodes on a network. On other systems, youll find services and applications using port 139. sign Force RPC pipe connections to be signed --------------- ---------------------- But it is also possible to get the password properties of individual users using the getusrdompwinfo command with the users RID. -c, --command=COMMANDS Execute semicolon separated cmds # lines. Query Group Information and Group Membership. SRVSVC | and SP2, and Server 2003 SP1 and earlier allows remote unauthenticated or authenticated attackers to In this lab, it is assumed that the attacker/operator has gained: code execution on a target system and the beacon is calling back to the team server, to be interrogated by 10.0.0.5 via 10.0.0.2. querydominfo Query domain info getdataex Get printer driver data with keyname There was a Forced Logging off on the Server and other important information. In our previous attempt to enumerate SID, we used the lsaenumsid command. The polices that are applied on a Domain are also dictated by the various group that exists. change_trust_pw Change Trust Account Password Hence, the credentials were successfully enumerated and the account can be taken over now. An attacker can create an account object based on the SID of that user. lsalookupprivvalue Get a privilege value given its name The createdomgroup command is to be used to create a group. -S, --signing=on|off|required Set the client signing state This is purely my experience with CTFs, Tryhackme, Vulnhub, and Hackthebox prior to enrolling in OSCP. It is also possible to add and remove privileges to a specific user as well. Nmap done: 1 IP address (1 host up) scanned in 10.93 seconds. . Enumerate Domain Groups. --------- -------, Starting Nmap 7.70 ( https://nmap.org ) at 2018-09-27 16:25 EDT In the demonstration, a user hacker is created with the help of a createdomuser and then a password is provided to it using the setuserinfo2 command. This command was able to enumerate two specific privileges such as SeChangeNotiftyPrivielge and SeNetworkLogonRight privilege. This is purely my experience with CTFs, Tryhackme, Vulnhub, and Hackthebox prior to enrolling in OSCP. This is an enumeration cheat sheet that I created while pursuing the OSCP. It enumerates alias groups on the domain. samlookupnames Look up names If this information does not appear in other used tools, you can: # Requires root or enough permissions to use tcpdump, # Will listen for the first 7 packets of a null login, # Will sometimes not capture or will print multiple. The command netsharegetinfo followed by the name of the share you are trying to enumerate will extract details about that particular share. After the user details and the group details, another information that can help an attacker that has retained the initial foothold on the domain is the Privileges. lsaquerysecobj Query LSA security object guest S-1-5-21-1835020781-2383529660-3657267081-1063 (Local Group: 4) This command retrieves the domain, server, users on the system, and other relevant information. {% code-tabs-item title="attacker@kali" %}. netname: ADMIN$ | This can be extracted using the lookupnames command used earlier. yet another reason to adjust your file & printer sharing configurations when you take your computer on the road (especially if you share your My Documents folder), Yeah so i was bored on the hotel wirelesserrr laband started seeing who had ports 135, 139, 445 open. This is an enumeration cheat sheet that I created while pursuing the OSCP. 139/tcp open netbios-ssn exit takes care of any password request that might pop up, since were checking for null login. MAC Address = 00-50-56-XX-XX-XX, [+] Finding open SMB ports. To demonstrate this, the attacker first used the lsaaddpriv command to add the SeCreateTokenPrivielge to the SID and then used the lsadelpriv command to remove that privilege from that group as well. All rights reserved. netfileenum Enumerate open files enumdrivers Enumerate installed printer drivers queryuser Query user info In the demonstration, it can be observed that the current user has been allocated 35 privileges. IPC$ NO ACCESS path: C:\tmp In the demonstration below, the attacker chooses S-1-1-0 SID to enumerate.

When provided the username, it extracts information such as the username, Full name, Home Drive, Profile Path, Description, Logon Time, Logoff Time, Password set time, Password Change Frequency, RID, Groups, etc. result was NT_STATUS_NONE_MAPPED 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). abortshutdown Abort Shutdown SMB2 Windows Vista SP1 and Windows 2008, nmap -n -v -Pn -p139,445 -sV 192.168.0.101, smbclient -L \\$ip --option='client min protocol=NT1', # if getting error "protocol negotiation failed: NT_STATUS_CONNECTION_DISCONNECTED", # Will list all shares with available permissions, smbmap -u jsmith -p password1 -d workgroup -H 192.168.0.1, nmap --script smb-enum-shares -p 139,445 $ip, smbclient \\\\192.168.1.101\\C$ --option='client min protocol=NT1', smbclient \\\\192.168.1.101\\admin$ -U t-skid, # Connect with valid username and password, smbmap -R $sharename -H $ip -A $fileyouwanttodownload -q, smbmap -u Administrator -p aad3b435b51404eeaad3b435b51404ee:e101cbd92f05790d1a202bf91274f2e7 -H $ip -s wwwroot -R -A '.

The next command to observe is the lsaquerysecobj command.
