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 Metasploit module emerged this week for a vulnerability silently patched by Microsoft in their July bulletin set. While the vulnerability is restricted to Internet Explorer 8, the publication of a simple exploit ensures that it will be used in the wild immediately.

47% of surveyed organizations have suffered a cyber-attack in the past year with a frightening 13% saying they do not even know if they have been attacked. These are among the results of the 2013 Cyber Security Study. Gain insight into the latest cyber security trends and download the report today

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Microsoft releases huge pile of patches
Description: Microsoft's monthly patch release this week contained a whopping 47 CVEs, spread across 13 total bulletins. Only a single one of the vulnerabilities was listed as having been previously disclosed, with no note on in-the-wild exploitation on any of the bugs. The patches, which run the gamut from privilege escalation to remote code execution, are certain to present fertile ground for attackers going forward, with exploits likely to emerge for at least some of the bugs in the near future.

Title: Silently patched Internet Explorer 8 exploit now has Metasploit module
Description: After being discovered by security researcher Orange Tsai earlier this year, and discussed at Hitcon 2013, a bug in Internet Explorer version 8 is gaining new life this week, with a fully functional Metasploit module for the attack being made public. Though the issue was silently patched in Microsoft bulletin MS13-055 this July, the widespread availability of a working attack makes it considerably more likely that exploitation will occur in the wild in the near future.

Title: Dropbox presents ASLR bypass for other programs when installed
Description: An independent security researcher this week made public a surprising consequence of running the popular Dropbox file-sharing software: doing so, at least on 32-bit systems, presents an ASLR-free zone for exploiting other high-risk applications, such as web browsers or file sharing clients. Specifically, Dropbox injects itself in DLL form into open windows, and as such can be used by exploits targeting the injected processes for code execution techniques that are typically mitigated by ASLR. Mitigation includes using EMET to force ASLR on all processes system-wide.
