XMLRPC or WP-Login: Which do Brute Force Attackers Prefer

XMLRPC compared to wp-login as an attack target in WordPress. Which is more frequently attacked and how to protect your site against brute force attacks.

Regarding US XMLRPC and Amazon —  

One possibility is that 36 servers at Amazon EC2 have been compromised and they have been used to launch a very rapid and wide-spread brute force attack during the past 2 weeks. That attack generated over 144 million failed login attempts across the sites we monitor.

An alternative theory is that a developer may be using EC2 to host an application that is trying to sign into WordPress websites using XMLRPC. The application may not handle bad user credentials correctly and may just keep retrying.

Cloud Shell Rumors Hint Thin Client Model for Windows – Windows Enterprise Desktop

“What would be more interesting is if Microsoft is truly trying to make a version of Windows for the masses that runs in the cloud and then streamed locally to your machine, much like a thin-client, but the details around Cloud shell are still a bit foggy.”

VNC over WebSocket tunnel. Practical tutorial for the remote office

Interactive desktop environments can be remotely accessed by using many technologies. Virtual Network Computing (VNC) is one of these.

In-depth article detailing exactly how to do VNC over WebSocket tunnel.  And excellent writeup/tutorial!

 

Excerpt: 

To evaluate if the WebSocket is a viable solution, we used VNCPlay[a], a set of tools to measure interactive performance. VNCPlay includes a VNC client that allows to record an interactive session and replay it under different system configurations. During the replay, the session output is saved into a log file. Two or more session logs can be fed to an analysis tool, included in VNCPlay, that produce response time statistics, which can be further elaborated. Response times to user activities are considered a good measure of interactive performance.

We built a test environment, composed of 3 LANs, that represent our “internet LAN”, the local network and the remote office network, and corresponds to the central, left and right parts in the figures above, respectively. The local and office LANs access to the internet LAN through two ZeroShell[b] router devices, each one configured to NAT the internal addresses to the router’s internet LAN address and to serve as default gatewayfor the internal LAN. The local LAN hosts the VNC client and the tunnel server with a port forwarding rule on the router to allow to connect to the tunnel server from the internet LAN. Similarly the office LAN hosts the tunnel client program and the machine running VNC server.

We used VNCPlay to record a test session, over a direct connection to the target machine with a Linux Mint OS.

Thin Client, a solution for schools

Working as an IT Manager (or even worse, to be in charge of a computer lab) at a school is a demanding work. Each teacher has his own needs.

Working as an IT Manager (or even worse, to be in charge of a computer lab) at a school is indeed a very demanding work.

 

As you can imagine, every teacher has his own needs and really many of them. Plus, their highly probable lack of IT knowledge is not very helpful for us,  technical assistants.

The problems that I am dealing with are more or less always the same:

 

1. Installation of multiple PC with many software (every teacher wants his or her own programmes that later are  used by students).

2. Heterogeneous and diverse PC parks (which means different installations and difficulties even for drivers and basic services).

3. Security issues (open USB ports, shared passwords).

4. High PC failure rates as apparently students don’t care too much to take a proper care of them.

So, what can we do? Is it possible to change this situation?
