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.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

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.

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.

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.
