Beyond the enumeration I show here, it will also help enumerate shares that are readable, and can ever execute commands on writable shares. If in the above example the ttl=127, then it is safe to assume (from this information alone) that the host, 10.10.10.10, is a Linux host. Forbid the creation and modification of files? Adding it to the original post. In the demonstration, it can be observed that the SID that was enumerated belonged to the Administrator of the Builtin users. Depending on the user privilege it is possible to change the password using the chgpasswd command. In the previous demonstration, the attacker was able to provide and remove privileges to a group. In the demonstration below, the attacker chooses S-1-1-0 SID to enumerate.

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. This problem is solved using lookupnames whereupon providing username the SID of that particular user can be extracted with ease. rpcclient $> lookupsids S-1-5-21-1835020781-2383529660-3657267081-1009 [+] User SMB session establishd on [ip] Once proxychains are configured, the attacker can start enumerating the AD environment through the beacon like so: Moving on, same way, they can query info about specific AD users: Enumerate current user's privileges and many more (consult rpcclient for all available commands): Finally, of course they can run nmap if needed: Impacket provides even more tools to enumerate remote systems through compromised boxes. | \\[ip]\wwwroot: A Little Guide to SMB Enumeration. Running something like ngrep -i -d tap0 's.?a.?m.?b.?a. Nowadays it is not very common to encounter hosts that have null sessions enabled, but it is worth a try if you do stumble across one. [hostname] <20> - M 139/tcp open netbios-ssn This command helps the attacker enumerate the security objects or permissions and privileges related to the security as demonstrated below. The next command that can help with the enumeration is lsaquery. The next command to demonstrate is lookupsids.

In the scenarios where there is a possibility of multiple domains in the network, there the attacker can use enumdomains to enumerate all the domains that might be deployed in that network. remark: PSC 2170 Series This is made from the words get domain password information. To do this first, the attacker needs a SID. Once we have a SID we can enumerate the rest. netname: ADMIN$ . quit Exit program This means that SMB is running with NetBIOS over TCP/IP**. Hashes work. Password attack (Brute-force) Brute-force service password. -l, --log-basename=LOGFILEBASE Basename for log/debug files | account_used: guest With --pw-nt-hash, the pwd provided is the NT hash, #Use --no-pass -c 'recurse;ls' to list recursively with smbclient, #List with smbmap, without folder it list everything. timeout connecting to 192.168.182.36:445 | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-0143 But it is also possible to get the password properties of individual users using the getusrdompwinfo command with the users RID. | and SP2, and Server 2003 SP1 and earlier allows remote unauthenticated or authenticated attackers to This can be done by providing the Username and Password followed by the target IP address of the server. logonctrl Logon Control # lines. To look for possible exploits to the SMB version it important to know which version is being used. The group information helps the attacker to plan their way to the Administrator or elevated access. May need to run a second time for success. server type : 0x9a03. logonctrl2 Logon Control 2 samquerysecobj Query SAMR security object It is possible to perform enumeration regarding the privileges for a group or a user based on their SID as well. Learning about various kinds of compromises that can be performed using Mimikatz we know that the SID of a user is the security Identifier that can be used for a lot of elevating privileges and minting tickets attacks. netname: IPC$ This lab shows how it is possible to bypass commandline argument logging when enumerating Windows environments, using Cobalt Strike and its socks proxy (or any other post exploitation tool that supports socks proxying). enumdomgroups Enumerate domain groups and Unix distributions and thus cross-platform communication via SMB. martin slumbers salary, riverbend correctional facility inmates,
