Don't Miss Pen Test Hackfest Summit & Training, November 2-9 near DC!

Newsletters: @RISK

@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

@RISK: The Consensus Security Vulnerability Alert

Vol. 13, Num. 39

Providing a reliable, weekly summary of newly discovered attack vectors, vulnerabilities with active exploits, and explanations of how recent attacks worked.



MOST PREVALENT MALWARE FILES 9/17/2013 - 9/24/2013

TOP VULNERABILITY THIS WEEK: Active exploitation of last week's Internet Explorer 0-day is continuing in the wild this week, with live exploit code beginning to appear on security research sites as of Tuesday. Since the public availability of exploit code generally leads to mass exploitation of broad-based vulnerabilities such as this one, administrators should assume that exploit kits and the like will incorporate the bug this week, and ensure that they have applied Microsoft's official FixIt while awaiting a full patch.

Title: Attacks against Internet Explorer 0-day continuing in the wild
Description: Despite a major wave of publicity following the discovery last week of a 0-day remote code execution flaw in Internet Explorer, and the release of a workaround by Microsoft, in-the-wild exploitation of the flaw (CVE-2013-3893) is continuing to take place, with security vendor FireEye releasing an in-depth report about attacks occurring specifically in Japan. Live exploit code began appearing on public security research sites by Tuesday of this week, and worldwide exploitation by exploit kits and other large-scale vectors is likely to begin occurring well before the October 8 release of Microsoft's standard patch cycle. System administrators are urged to ensure that Microsoft's temporary fix has been applied immediately.

Title: Apple iPhone TouchID broken
Description: The Chaos Computer Club - one of the planet's oldest hacking organizations - was declared the official winner of a bounty program that sprung up over the weekend to crack the new touch ID authentication system in new iPhone 5 hardware, after the group successfully lifted a print, replicated it with commonly available technology, and gained access to a phone protected by the system. The contest featured its share of hacker drama, after a pledge of $10,000 to the crowd-funded bounty was made by a venture capitalist who later reneged on his promise, after having received considerable media coverage for the pledge.

Title: Fake iMessage for Android surfaces, sends data to China
Description: An unofficial Apple iMessage client appeared in Google's Android market this week, with tens of thousands of downloads before being pulled by Google. Several security researchers independently noted that the application sent copies of all of the user's data to an IP address in China without any warning to the end user. While the developer of the app insisted that the data being sent was for legitimate purposes, the episode shows how easy it is for rogue apps to harvest huge amounts of data from unsuspecting users even in relatively well-policed markets such as Google Play.

Title: Java reflection attack allows remote code execution on Android < 4.2
Description: Security research firm MWR InfoSecurity released an advisory this week detailing a reflection attack against the addJavaScriptInterface functionality offered by the Android operating system's WebKit component, which allows developers to define methods which can be called by JavaScript. Although the original intent of the functionality was to expose only clearly defined methods, a trivial sequence of calls could allow full command execution by malicious web pages if any methods are exported at all through this interface. While the issue has been fixed in Android 4.2, MWR's research shows a wide array of popular apps and ad networks still vulnerable to attacks.
