RUCTF 2014 Quals Forensics-100 [Secret host]

Forensics-100
We intercepted configs and dump. What were they hide on http://10.100.0.1/?

Search for password and username for the openvpn connection using the MDMP crash dump.
Using "strings" command or using Hexdump you can find these username and password.

So we got the username : SuperPuperRoot and password : VeryStrongSecret

Install openvpn here.

You need to place the certificate file and the config file(Extracted from the configs and dumps) in "openvpn configuration file directory" like this.
