SSl stripping with SSLstrip and Arpspoof

SSL Stripping is a technique by which a website is downgraded from https to http. With standard SSL man-in-the-middle attacks, users have to click through the SSL certificate warning. Depending on the browser, this can be an involved process that is difficult, if not impossible, for a user to ignore. Most readers can probably think of a time they clicked through a security warning and continued to the page despite their better judgment. With SSL stripping, we man-in-the-middle the HTTP connection before it is redirected to SSL and add SSL functionality before sending the packets on to the web server. When the web server replies, SSL stripping again intercepts the traffic and removes the HTTPS tags before sending the packets to the client.

Remote desktop with Apache Guacamole

A few days ago I hired a server to build a lab and play around with some configuration scenarios. I decided to run it on free version of VMware ESXi hypervisor. It was easy to deploy few VMs there, but standalone ESXi and it’s console is not the best way to connect and manage vitrual machines. Unfortunately, there is no free version of vCenter, which could I use to manage machines. After few minutes of searching for solution in google, I found something calles Guacamole – a clientless gateway, which supports standard protocols like VNC, RDP, and SSH, and allows to access your remote desktops via web browser.
