@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.

@RISK: The Consensus Security Vulnerability Alert

Vol. 13, Num. 32

Providing a reliable, weekly summary of newly discovered attack vectors, vulnerabilities with active exploits, and explanations of how recent attacks worked.




TOP VULNERABILITY THIS WEEK: Attacks against the version of Firefox distributed in the Tor Browser Bundle were discovered in the wild this week, with a payload that sent users' MAC addresses to an IP address presumed to be controlled by the federal government. The announcement comes as a major blow to Tor, previously presumed to be the most secure way to preserve anonymity on the Internet.

1) August 21 Webcast! Managing Identities in the Cloud Without Sacrificing Corporate Control: A Review of McAfees Web-Focused Identity Tools, featuring Dave Shackleford


Title: Firefox 17 bug exploited to de-anonymize Tor users
Description: A Javascript bug in Firefox version 17.0.7, the version released as part of the Tor Browser Bundle, has been observed being exploited in the wild with a payload that de-anonymizes the infected user. Tracking information collected by this malware was then sent to a hard-coded IP address in northern Virginia; speculation has run rampant among the security community about the ultimate owner of the address, with signs pointing towards the federal government. While a fix for the bug enabling the attack is available, the issue highlights the difficulty of ensuring anonymity on the Internet, even when using supposedly secure services such as Tor.

Title: OpenX server packages backdoored since November 2012
Description: An announcement this week from the OpenX ad server team noted that a backdoor had recently been discovered in their official source code distributions, and that the backdoor has been present since November 2012. While packages have since been cleaned, exploitation is occurring in the wild, with attacks consisting of simple POST requests to a specific file that allow for remote code execution on the infected server. Users are urged to follow simple instructions being provided by the community for checking their servers, and cleaning any that are infected immediately.

ClamAV: Backdoor.OpenX.CVE_2013_4211

Title: APT1/Comment Crew discovered breaking into a honeypot of a water plant
Description: A security researcher at Trend Micro detailed last week at Black Hat how the now-notorious Chinese hacking group known alternately as APT1 or the Comment Crew was discovered this past December breaking into a decoy water plant, which they were able to gain complete control over. The other attacks against industrial honeypots showed the ease with which attackers can compromise such systems, and raises the very real possibility that municipalities around the world are already compromised by live attackers.

Title: Android weblogin shown to be vulnerable to trivial social engineering attacks
Description: Researcher Craig Young of Tripwire demonstrated last week at Defcon how Android applications which request permissions to interface with the Google applications suite can take tokens which grant access to one service, such as YouTube, and then use them throughout the Google ecosystem, granting attackers the ability to change passwords, alter domain services, access email and calendars, etc. While Google has already made some fixes that require additional authentication beyond weblogin tokens for sensitive operations, many issues remain; additionally, the app used to demonstrate the problem was deployed successfully on the Google Play store, demonstrating how easy it would be for a malicious application to exploit this ecosystem weakness.

Title: Java Applet ProviderSkeleton Insecure Invoke Method
Vendor: Oracle
