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 trivially exploitable remote root vulnerability exists in the Kindle Touch built-in browser. Based on its support for the NPAPI, commands can be injected with root-level privileges with no authentication, simply by visiting a web page. Exploits are presumed to already exist in the wild.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Remote Root Exploit in Kindle Touch
Description: The built-in browser for the Kindle Touch integrates support for the Netscape Plugin API, a modern cross-browser scripting language. Unfortunately, it is implemented in such a way that it allows injection of commands into the browser with root privileges. While the API is poorly documented, and few public details about exploitation currently exist in the wild, exploits will be trivial to write and should be presumed to exist at this point.

Snort SID: 23616, 23617
ClamAV: N/A

Title: Arbitrary Remote File Upload in Wordpress Invit0r Plugin
Description: The WordPress Invit0r plugin, which can be used to invite Yahoo contacts to visit your blog, has an arbitrary remote file include vulnerability. While it has been pulled from the official Wordpress plugins site, multiple public exploits exist and are being actively used in the wild. While this particular plugin is not especially notable, it highlights the ongoing challenge of securing Wordpress and other CMS systems, and the dangers created by such sites being exploited and used to host malware.

Snort SID: 23484, 23485
ClamAV: N/A

Title: ZeroAccess Trojan Continues To Spread
Description: The ZeroAccess trojan/rootkit, a particularly nasty piece of malware that was first discovered in the wild in early 2012, is today considered by some to be one of the top threats to end-users in the wild. The Sourcefire VRT has been following this malware recently, and has new signatures for command-and-control traffic generated by infected systems. As this malware has been known to cause users to exceed bandwidth caps and be charged by their ISP directly, users both corporate and private are encouraged to check their systems for signs of infection regularly.

Snort SID: 23492, 23493
ClamAV: Trojan.ZeroAccess-1 - Trojan.ZeroAccess-693

Title: Use of XML Templates To Embed Malware In PDFs
Description: The Sourcefire VRT has received multiple reports of malicious PDFs being distributed in the wild that embed their malicious content inside of an XML tempalte within the PDF. After extensive testing across thousands of PDF files, both malicious and benign, the VRT has determined that the number of legitimate uses of this functionality in the field today is so low that detection of such documents generically is a useful way to detect new malware variants. As always, users are highly encouraged to keep their PDF parsing applications up-to-date at all times.
