OUCH! Security Awareness

@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. 12, Num. 39

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



MOST POPULAR MALWARE FILES 9/18/2012 - 9/25/2012

TOP VULNERABILITY THIS WEEK: American financial institutions are being targeted for DDoS attacks, with Bank of America having been knocked offline briefly last week. The perpetrators are unknown, with suggestions ranging from political activists to the Iranian government, but data about the attacks is all over PasteBin, from pre-announcements of attacks to the tool being used by the attackers.

Title: Operation Ababil DDoS Campaign
Description: A DDoS campaign against US financial institutions dubbed "Operation Ababil" has been going on since last week, with new attacks announced on PasteBin as of Tuesday. While a group called "Cyber fighters of Izz ad-din Al qassam" has claimed credit, citing outrage over the same controversial film that has caused riots throughout the Arab world, US officials including Senator Joe Lieberman have insinuated that Iran is actually sponsoring the attacks, questioning the ability of a group of activists to take down major corporations such as Bank of America and Chase. The Sourcefire VRT has intelligence indicating that the attacks, wherever their origin, are using a script dubbed "itsoknoproblembro" (so called because of a status message it displays), which originally surfaced on PasteBin in January of this year.

Title: Symantec Norton Utilities 2006 source leaked on PirateBay
Description: Actors under the banner of Anonymous posted what they claim to be source code for the Symantec Norton Utilities 2006 security suite on PasteBin this week, along with a message deriding the quality of the code that asked Symantec to quit writing "shitty" software. This is the second time this year that Symantec source code has been leaked; in February, code for pcAnywhere was posted after a failed attempt to extort $50,000 from the company.
Snort SID: N/A

Title: Crimeboss Exploit Kit
Description: A relatively new exploit kit dubbed Crimeboss has recently been observed circulating in the wild, exploiting Java vulnerabilities such as the recently patched 0-day CVE-2012-4681. The kit, which is not particularly novel in terms of obfuscation or deployment, is interesting in that it both gives you the opportunity to install Java if you have not done so already, and also delivers an applet which does not attempt to exploit a vulnerability, but merely asks you to run it instead. In addition, the payloads it drops are disguised as image files, bypassing many web filtering techniques for executables in an attempt to boost its success rates.
Snort SID: 24231 - 24234
ClamAV: N/A

Title: CrimeTLS Attack
Description: Security researchers Juliano Rizzo and Thai Duong presented a new way of determining parts of the content of an encrypted message without the need to fully decrypt the message last week at the Ekoparty Security Conference, dubbed the Crime TLS attack. The technique relies on compressed TLS-encrypted data, and revolves around the fact that an attacker who can control a portion of a request will notice a size difference in the compressed data when they have successfully matched their portion of the request with the data that they wish to disclose in the TLS request. While the vulnerability is serious in theory, and has been demonstrated on live systems including Twitter, it can easily be worked around by disabling TLS compression on the client or server side, and as noted by the researchers, only works on around 40% of systems in the wild even without mitigating steps.
