Last Day for MacBook Air, Dell XPS 13, or $600 Off with Online Training

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: Last week's new Java 0-day, CVE-2013-1493, has been spotted in the wild in Cool Exploit Kit, and is likely to work its way into other kits in the near term. Users who have not or cannot patch should consider using their browser's "click to play" solution, if available, which would require a user to click on an applet to allow it to run, thereby taking attacks like these from automatic after a click to a state where further user interaction is required for exploitation.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Recent Java 0-day Added To Cool Exploit Kit
Description: Researchers have spotted last week's Java 0-day in the high-end Cool Exploit Kit, marking a shift from originally being a targeted attack to a mass-market one. The vulnerability is likely to appear in other exploit kits as details on exploitation become more widely available in the underground; users are urged to patch immediately if they have not already. Those who have not patched should also strongly consider Click-to-Play if available in their browser, which requires users to actually click on an applet to allow it to run, helping to minimize harm from drive-by exploit attempts.

Title: Microsoft Releases Patches for 20 CVEs
Description: Microsoft dumped another large Patch Tuesday on the Internet this week, with 7 bulletins covering a total of 20 CVEs. While none of the bugs are currently being exploited in the wild, the slew of user-after-free bugs in Internet Explorer are likely to be targeted by attackers in the coming weeks, as reverse engineers have a chance to examine and break them apart. Users are urged to patch as soon as feasible.

Title: TP-Link Router HTTP Backdoor
Description: An advisory was released on Monday detailing how to gain a shell on certain TP-Link routers, popular in the SOHO market, simply by querying a specific URL on the device. While it was unclear at the time of publication whether this could be accessed only while on the internal network, this is the second remote shell problem with that type of router in the last year; users may wish to consider switching models at the next feasible opportunity.

Title: New Attack on TLS Disclosed
Description: Researchers at the Royal Holloway University of London released on Wednesday details of a new attack against TLS when RC4 is used as a block cipher. While not as severe as previous attacks such as BEAST - this new attack can only recover 220 bytes of cleartext data from a packet, and then only after at least 2^24 sessions have been analyzed - this further flaw in the protocol pushes TLS/RC4 one step further towards obsolescence. Patches are currently under development by impacted vendors; users are urged to use different cyper suites wherever possible in TLS transactions.
