Weekly infosec news summary for 2016.10.02 – 2016.10.09
This was an uneventful week for enterprise defense.
- TalkTalk fined $500K over last year’s cyber attack: TalkTalk was hacked last year, causing its stock to drop (see my analysis from then here). It has finally been fined, receiving nearly the maximum fine possible.
Conference materials and publications

- MacOS Hardening Guide: Jonathan Levin, author of "MacOS and iOS Internals, Volume III: Security & Insecurity" which will be released this coming week, has released his appendix, the MacOS Hardening Guide. This doesn't provide a lot of actionable steps, but lays out some general thoughts on things that can be done, such as recompiling the kernel, which is open-source, and setting SECURE_KERNEL to 1.
- The Container Revolution: Reflections After the First Decade: This talk from the Hashiconf conference (focused on devops tools), discusses the three decades of containerization.

- Yahoo secretly scanned customer emails for U.S. intelligence: The summary of the story as presented in the news is that Yahoo execs complied with a court order to install some special government software to scan customer emails, which Alex Stamos, the CISO at the time, didn't know about until his security team discovered it, causing him to quit. Privacy debates and surveillance laws aside, the important take-away here is ensuring you have policies and technical controls in place to identify changes to your production infrastructure, and being able to detect "inside threats" like this, which may even involve teams of people.
