Re: "exfiltrating"? WTF does that mean?
Exfiltrating is the term used in security when an attacker sends stealthily out the data she has stolen in a system. The objective is to avoid detection. This terminology is widely used when describing Advanced Persistent Threats (APT), which is what this article describes. RSA published last year an excellent report on this topic.
