[net-security] all need Authentication most need Domain Controllers 'n hackers love it

Background:
Domain Controllers are devices responsible for maintenance of data about all corporate user accounts, software resources and user ACLs. So, specific vulnerability assessment was required for them. We were supposed to assess the Domain Controllers with a more intense vulnerability scan cycle.

Execution Method:
Similar to previous task, we first scanned using NMap, and then launched NeXpose Scans on the domain servers one by one.
The scan result showed that all the machines ran the exploitable services and we tried testing those using Metasploit and tools specific to the identified vulnerability.
Here, we especially checked for User Account Enumeration and found most of the Domain Controllers to be vulnerable to CIFS Vulnerabilities, resulting in enumeration of all User Accounts with their details.

Tools/Technology Used:
NMap, Rapid7's NeXpose, Metasploit, SNMP Fuzzer, SNScan, Hunt, SuperScan, User2SID, SID2Use

[net-security] Internal Network Scan : major NeXpose work

Background:
Even if a network has strong intrusion detection and prevention mechanism implemented, it is as safe as machines present within the network. If any network device within the network is infected with Trojan, Virus or even running a vulnerable service; it could lead to the compromise of entire network.

Execution Method:
Rapid7 team of Metasploit, have a network vulnerability assessment tool named 'NeXpose'.
It has a huge, regularly updating database of exploits and vulnerabilities to be tested against limited set of machines in its Community Version.

First start scanning the subnets with the best network scanner, NMap revealing some interesting information about Machines, Ports and services running on those ports.

Next, launch NeXpose Scans for all machines identified in the first step in small batches. Here, NeXpose will again do some NMap like testing and a lot more extra self-checking of whether certain exploit is useful against the machine.
Keep a record of all machines with exploitable services and tried hacking those using Metasploit and tools specific to vulnerabilities.


Also use tools like SNMPFuzz, Hunt mainly on server like machines... say AD Server, etc.; you could get lucky anytime.
