Apple updates iOS and Apple TV
Apple sent out 3 bulletins and OS updates today (iOS 6.1.3, iOS 7.0.6, and Apple TV 6.0.2) all fixing a bug that would potentially allow SSL/TLS connections to be vulnerable to undetected man-in-the-middle attacks. All three updates share the same CVE number CVE-2014-1266. The Apple Security updates page does not yet appear to have the updates listed there, but they should be there shortly (may be there by the time you read this). If you have an Apple device running iOS 6 or 7 or Apple TV, you should probably apply these updates ASAP.

UPS Malware Spam Using Fake SPF Headers
The "Sender Policy Framework" is a simple system to identify which mail servers are allowed to send e-mail on behalf of your domain. We have talked about this (and other standards like DMARC, DKIM) before.
These systems are usually implemented on your mail gateways. The outbound gateway will sign e-mail using your domain key (for DKIM). The receiving mail gateway will check if the headers are present and correct. The mail gateway will then add a special header with the result of the check, and this special header is then used by spam filters to decide if to keep the e-mail (or not).
It appears that spammers are learning and found a way to fool some badly configured mail gateways and spam filters. The spammer will add a header indicating that the e-mail passed the SPF validation. William sent us a sample of a UPS themed e-mail that included a malicious attachment. It included the following headers:
Subject: UPS Delivery Notification Tracking Number : <random string>

The red line indicates that the e-mail passed SPF validation. However, if you are checking the UPS.com SPF record:

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
