A take on the security news, week 36 / 2015. I summarize some of the news that I considered noteworthy related to information security this week.
Vulnerable babymonitors, Yosemite and Linux hardening guides, Microsoft tracking users, iOS malware, OSX malware and browers soon to end support for RC4


Automating metrics using your ticketsystems API

An interesting idea is that your incident handling system automatically creates issues in your issuetracker when needed. If your ihs automatically creates tickets in your ticketingsystem when a breach, phishing attack or similar is detected, you will get aware of it a lot sooner than if you have to wait for someone create the issues manually.

An example of how it can be solved if you use the open source RTIR incident handling system can be found in the link below.

Interesting reading about how the Linux Foundation are hardening their clients. Most hardening guides are targeting servers so this comprehensive list is worth a reading. The guide is rating the different advices as 'essential', 'nice' and 'paranoid. Implement the advices that suits your environment.

Secureboot, full disk encryption and filtering all your incoming ports are among some of the 'essential' advices you should consider in your environment.

I.e "how to hack" yields: facebbok, wifi and clash of clans on top 3. Your mileage may vary based on when you do the search, your search history and country.


Microsoft backports usertracking to Windows 7 and Windows 8

The arrive of Windows 10 have brought a whole new set of usertracking tools and policies from Microsoft. It is suspected that all the datacollection on Windows 10 is one of the reason that people are not upgrading yet, but stays with their already running Windows 7 or Windows 8.

There is no reason for that anymore since Microsoft now backports the usertracking and "updates" Windows 7/8 so that users can be tracked on those platform too. KB3068708, KB3022345/KB3068708, KB3075249 and KB3080149 are updates that are relevant for usertracking on Windows 7 and Windows 8. It also seems that data goes to at least the following two adresses vortex-win.data.microsoft.com and settings-win.data.microsoft.com, which is hardcoded into the system making it difficult to bypass with the hosts file.

Its time to search for a disable usertracking on windows guide, which there are plenty of.


Malware using the DYLD_PRINT_TO_FILE vulnerability on osx

This is an update of an already existing malware, but updated so it bypass the osx malware blocking list. The malware installs Genieo, VSearch, MacKeeper and point to the AppStore version of Download Shuttle, but the new trick is that when its done with the "legitimate" programs a new image (named installer) is mounted and it asks for access to your Safari Extensions List in your keychain. Instead of waiting for the user to deny this request it goes ahead and control the mouse, clicking accept and then goes ahead installing malicious plugins to your Safari browser.

Apple has now pushed XProtect signatures for OSX.Genieo.C, OSX.Genieo.B and OSX.Genieo. Also note that this malware is asking the user for administrator password as part of the process, so if you dont install unknown software on your machine you should be safe anyway.



OSX Yosemite security and privacy guide

Following the Linux Foundation hardening guide earlier this week I stumbled upon a similar thing for Yosemite. Comprehensive and detailed, pick whatever suits your environment.

Browsers stop support for RC4

Google, Mozilla and Microsoft will stop supporting RC4 encryption starting early next year. The RC4 cipher is old and is proven unsecure in a way that make it trivial to break.

For most cases TLS will pick the strongest cipher (not RC4), but in some cases it will fallback to a less secure cipher. When browser stop support RC4 they will fail instead of downgrade the cipher.

The impact of this is minimal since a very small percentage of browserusers are actually using RC4 anymore.
