Attack Analysis

a11y.text Attack Analysis

Wow! That was a lot of output! Please take some time to read through the output, and try to understand what is happening.

Let’s break down some of the output a bit here.

[*] DNS 10.0.0.100:1284 XID 92 (IN::A ecademy.com)
[*] DNS 10.0.0.100:1286 XID 93 (IN::A facebook.com)

[*] DNS 10.0.0.100:1287 XID 94 (IN::A gather.com)

Here we see DNS lookups occurring. Most of these are initiated by Karmetasploit in attempts to gather information from the client.

Here we can see Karmetasploit collecting cookie information from the client. This could be useful information to use in attacks against the user later on.

Here is where it gets really interesting! We have obtained the password hashes from the system, which can then be used to identify the actual passwords. This is followed by the creation of a Meterpreter session.

Now we have access to the system, lets see what we can do with it.

Wonderful. Just like any other vector, our Meterperter session is working just as we expected.

However, there can be a lot that happens in Karmetasploit really fast and making use of the output to standard out may not be usable. Let’s look at another way to access the logged information. We will interact with the karma.db that is created in your home directory.

Lets open it with sqlite, and dump the schema.

root@kali:~# sqlite3 karma.db
SQLite version 3.5.9
Enter ".help" for instructions
sqlite> .schema
CREATE TABLE hosts (
'id' INTEGER PRIMARY KEY NOT NULL,
'created' TIMESTAMP,
'address' VARCHAR(16) UNIQUE,

'desc' VARCHAR(1024),
'os_name' VARCHAR(255),
'os_flavor' VARCHAR(255),
'os_sp' VARCHAR(255),
'os_lang' VARCHAR(255),
'arch' VARCHAR(255)
);
CREATE TABLE notes (
'id' INTEGER PRIMARY KEY NOT NULL,
'created' TIMESTAMP,
'host_id' INTEGER,
'ntype' VARCHAR(512),
'data' TEXT
);
CREATE TABLE refs (

'ref_id' INTEGER,
'created' TIMESTAMP,
'name' VARCHAR(512)
);
CREATE TABLE reports (

);
CREATE TABLE requests (

'path' BLOB,

);
CREATE TABLE services (

'port' INTEGER NOT NULL,
'proto' VARCHAR(16) NOT NULL,
'state' VARCHAR(255),
'name' VARCHAR(255),
'desc' VARCHAR(1024)
);
CREATE TABLE targets (
'id' INTEGER PRIMARY KEY NOT NULL,
'host' VARCHAR(20),
'port' INTEGER,
'ssl' INTEGER,
'selected' INTEGER
);
CREATE TABLE vulns (
'id' INTEGER PRIMARY KEY NOT NULL,
'service_id' INTEGER,
'created' TIMESTAMP,
'name' VARCHAR(1024),
'data' TEXT
);
CREATE TABLE vulns_refs (
'ref_id' INTEGER,
'vuln_id' INTEGER
);

With the information gained from the schema, let’s interact with the data we have gathered. First, we will list all the systems that we logged information from, then afterward, dump all the information we gathered while they were connected.
