5 Days Left to Save $200 on SANS Miami 2016

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: Moving approximately 10 days after in-the-wild exploits were discovered, Microsoft this week patched CVE-2013-1347, a remotely exploitable IE8 issue for which Metasploit and other public exploit code exists. This month's patches included fixes for 32 other CVEs across 10 bulletins, including issues exploitable with the bochspawn tool presented as Syscan 2013 last month.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Microsoft Tuesday release fixes IE8 0-day, 33 total CVEs
Description: The recently discovered IE8 0-day, which has been circulating with weaponized exploit code for over a week now, was patched in this week's Microsoft Tuesday release. The patches, which cover 33 CVEs across 10 bulletins, include fixes for a number of "double fetch" kernel-level vulnerabilities disclosed in Mateusz Jurczyk and Gynvael Coldwind's Syscan 2013 talk, as well as several other remotely exploitable issues for which no public code is yet available. Administrators are urged to patch promptly, as further exploits are likely to appear in the wild in the short term.

Snort SID: 26569-26572, 26622-26642
ClamAV: N/A

Title: ColdFusion 0-day appears in the wild
Description: A trivially exploitable (from a web browser) vulnerability appeared in the wild, complete with sample exploit code, for all versions of ColdFusion last week. The vulnerability, which can result in disclosure of administrative credentials, results from a common misconfiguration, and can easily be fixed by either applying the recently supplied patches from Adobe or locking down potentially vulnerable servers.

Title: Regents of University of Louisiana site compromised, served Sirefef malware
Description: Typical of a long-term trend in the current threat landscape, the web site of the Regents of the University of Louisiana was recently compromised via a Wordpress vulnerability, and used to serve the notorious Sirefef malware to anyone visiting the site. Wordpress administrators are urged to lock their sites down as tightly as possible, and to consider running IDS signatures such as Sourcefire SID 26618, which detect malicious executables being served from within your protected network, to help respond to incidents like these promptly.
