Typical use case for Egress-Assess is to copy this tool in two locations. One location will act as the server, the other will act as the client. Egress-Assess can send data over FTP, HTTP, and HTTPS.
|
||||
|
||||
To extract data over FTP, you would first start Egress-Assess’s FTP server by selecting “–ftp-server” and providing a username and password to use:
|
||||
To extract data over FTP, you would first start Egress-Assess’s FTP server by selecting “--server ftp” and providing a username and password to use:
|
||||
|
||||
./Egress-Assess.py –ftp-server –username testuser –password pass123
|
||||
./Egress-Assess.py --server ftp --username testuser --password pass123
|
||||
|
||||
Now, to have the client connect and send data to the ftp server, you could run...
|
||||
|
||||
./Egress-Assess.py --ftp --username testuser --password pass123 --ip 192.168.63.149 --ssn
|
||||
|
||||
./Egress-Assess.py --client ftp --username testuser --password pass123 --ip 192.168.63.149 --datatype ssn
|
||||
|
||||
Also, you can setup Egress-Assess to act as a web server by running....
|
||||
|
||||
./Egress-Assess.py --http-server
|
||||
./Egress-Assess.py --server https
|
||||
|
||||
Then, to send data to the FTP server, and to specifically send 15 megs of credit card data, run the following command...
|
||||
|
||||
./Egress-Assess.py –http –data-size 15 –ip 192.168.63.149 –cc
|
||||
|
||||
|
||||
Upcoming Changes
|
||||
================
|
||||
|
||||
1. Make Egress-Assess modular so users can easily extend the tool to support additional frameworks and data types.
|
||||
./Egress-Assess.py --client https --data-size 15 --ip 192.168.63.149 --datatype cc
