Bruce Schneier writes about how some Chinese hackers are bypassing RSA software token authentication (the title is a bit more broad, implying other forms of two-factor authentication are affected, but the article focuses on attacks against the use of RSA software tokens). This article has a list of tips and tricks for zsh.

I’m assuming that you’ve already gone through the process of getting KVM installed on your Linux host; if you need help with that, a quick Google search should turn up plenty of “how to” articles (it’s basically a sudo apt-get install kvm operation). Next, you need to authenticate the hypervisor to NVP.

Mozilla moves towards multi-factor authentication. In an article reported earlier by SecureWorld News, we covered Microsoft's new "passwordless" technology , which is actually multi-factor authentication (MFA). Now, we need to incorporate something called authentication that integrates with access on the other side.

The fleetctl doesn’t expose any options to configure the SSH connection, and it assumes you’ll be using public key authentication. OS X provides an SSH agent by default, but on Linux systems you will probably have to manually run an SSH agent and add the appropriate SSH key: eval `ssh-agent -s` ssh-add ~/.ssh/keyfile.pem.
