Last Chance: MacBook Air, Dell XPS 13 or $600 off with SANS Online Training Ends December 7

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.

TOP VULNERABILITY THIS WEEK: A 0-day was discovered in Java by researchers who saw it being used in several distinct exploit kits. While Oracle has released a patch, which includes requiring users to click an applet to run it by default, US-CERT has advised everyone who does not need Java to disable it in their browser immediately.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Java 0-day attack exploited in the wild
Description: Researchers last Thursday discovered a 0-day attack against the latest version of Java being exploited in the wild by a series of exploit kits, with owners of multiple kits claiming responsibility for having added the attack to their kit first. After US-CERT released an advisory recommending that anyone who does not use Java regularly disable it immediately, Oracle issued a patch on Sunday, which included a change to Java's security settings that would require users to click on an applet to allow it to run. While experts are praising that settings update as a proactive defensive mechanism, researchers from Immunity on Monday noted that the patch issued by Oracle - while effective against attacks currently in the wild - did not completely resolve one of the underlying issues with this bug, leaving the door open for further attacks in the future. The VRT strongly recommends following US-CERT's guidance on the issue and disabling Java if possible, while being vigilant on patches if it must be left enabled.

Title: Ruby on Rails vulnerability could be largest server-side web bug in years
Description: A pair of remotely exploitable vulnerabilities were discovered in the popular Ruby on Rails web programming framework last week, one of which allows for code execution in default installations with the permissions of the application running Rails code. While estimates on the number of vulnerable sites vary, experts agree that number could easily be north of 1 million systems, making this one of the most widespread server-side exploits in years. An official patch has been issued (including a patch for the popular Metasploit framework, which was itself vulnerable), and system administrators are urged to patch immediately, as exploits are known to be circulating in the wild.

Title: Anonymous takes down MIT sites after suicide of Aaron Swartz
Description: Well-known activist Aaron Swartz, while awaiting trial on charges related to allegations that he had made publicly available the entire subscription-only section of the JSTOR database of scholarly journals and a large section of copyrighted documents at MIT, took his own life last Friday. Amid allegations that he was driven to suicide by overly zealous prosecution, Anonymous defaced several MIT sites in a show of support for Swartz and his crusade for online openness, and a petition has surfaced to remove the federal prosecutor handling the case for being overly zealous in his prosecution. The case raises questions about copyright prosecution in the 21st century, particularly in light of the fact that Swartz was facing a 35-year sentence even after JSTOR had asked the federal government to drop its prosecution and allow them to pursue civil action instead.

Title: Researchers discover "Red October" worldwide cyber espionage campaign
Description: Kaspersky Labs released a major report this week on a highly sophisticated, long-term malware campaign designed to infiltrate diplomatic circles and collect data valuable to both state and private actors. According to their analysis, which has held up well to scrutiny from independent researchers, the campaign has been running since at least 2007, and includes Chinese-created exploits and malware code from Russian-speaking engineers. The malware was delivered via highly targeted spear phish, and used a variety of exploits in MS Office and other file formats to break into victim machines. While the total number of infected hosts was low, this discovery helps to highlight the extreme danger high-profile organizations face from online espionage in the modern era.
