High Frequency Trading isn't new... http://en.wikipedia.org/wiki/High-frequency_trading This past June, a news article caused a $28million dollar gain: "If you’re a high-frequency trader, a few milliseconds is a big deal. And in this case, a 15-millisecond head-start meant that $28 million in shares traded hands before the number was even published, http://qz.com/91242/the-15-millisecond-head-start-that-led-to-28-million-in-trades/" This shouldn't come as a surprise that companies in the business of making money will do everything that they can to (drum roll...) make money

You're missing the gist of it here. The reality on production server is, most are locked down from egress attacks. This does not stop, minimize, and or deter an attacker from hitting you up with a client side attack on a non-production machine, passing a hash, then to and from trusted sources until it gets out: Attacker --> client side --> workstation workstation --> attack --> production server production server workstation workstation --> via SSL --> attacker. This would fill a wiki page so I will stop there. There was a point to be made without me having to spell things out

I believe there is more going on to this than you would understand. For example, the Zeus/Qakbot strain always downloads a file. Most times it will be randomized. For arguments sake, lets say it was named nbc.exe. What Zeus/Qakbot did was communicate out via IE. Even though the nbc.exe was the application responsible for running the show, the communications portion was done via good ole GET and POST via HTTPS. At issue with detecting nbc.exe where Zeus/Qakbot was/is concerned, is the fact that the operators of the malware were/are changing the executable N amount of hours. So most AV systems wouldn't even detect it. So no... IPS/IDS here means nothing. Blacklisting *may* have worked to stop the communication, but even then a fast flux would have trumped that.

Any IDS/IPS is only as good as its signatures. The problem with these devices is that attackers can use a flurry of heuristic tactics to completely bypass these systems as well as DLP. There is a difference had you mentioned SIEM which *may* have worked if there were vigilant analysts looking at logs repeatedly. In order to understand why IDS/IPS' fail, you need to understand attacks. At any point in time, when I perform pentests, I ALWAYS start off sending a barrage of data to generate junk. This is done for a few reasons: 1) it tests responses from DFIR teams and 2) allows me to get in under the radar. Now when you state: "machines communicating encrypted data to site out on the Internet is something that IDS applications are designed to detect" you're 10000000% wrong. Any IPS/IDS admin doing this is giving themselves a headache. Do you have any idea how many false positives it would generate from employees going to log into say Gmail, their banks, or anything else using SSL.

While I understand WHY the USPS would do this, I wonder how much money they've spend on storing data (the photos) all the while cutting the hours of employees due to budget cuts, etc. as for the comment by Bruce Schneier: "whether it was a postal worker taking down information or a computer taking images, the program was still an invasion of privacy." I disagree. There is a difference between taking an address down and reading your mail. I don't see Bruce complaining about UPS, FedEx, etc. doing the same. Get over it
