TOP VULNERABILITY THIS WEEK: Adobe code signing infrastructure was

compromised and malware was found in the wild that appeared to be signed
using a valid Adobe certificate. There could potentially be thousands
of malicious files out there that users could be tricked into running
thinking that they are from a trusted source.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Adobe code signing certificate stolen
Description: Not a typical vulnerability, but a vulnerability
nonetheless. Adobe code signing infrastructure was compromised and
malware was found in the wild that appeared to be signed using a valid
Adobe certificate. There could potentially be thousands of malware
samples that users could be tricked into running thinking that they are
from a trusted source.
Adobe plans to revoke all code signed after July 10, 2012 on October 4,
2012 and will have little to no impact on genuine Adobe software. More
information about the impact of the revocation can be found here.

Title: DDoS attacks against US banks
Description: Over the last two weeks, cyberattacks have disrupted the
websites of U.S. banks, including Wells Fargo, U.S. Bank, PNC Bank, Bank
of America and JPMorgan Chase. While a group called “Cyber fighters of
Izz ad-din Al qassam” has claimed credit, citing outrageover 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. 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: Android dialer USSD code execution
Description: A vulnerability can allow an attacker to execute USSD codes
automatically without user permission. Phone running Android 2.3.x ,3.x,
4.0.x and 4.1.x are vulnerable to the USSD attack.
A user could use their phone visit a webpage that contains malicious
code to permanently kill the SIM card or remotely wipe the device. Note
that the remote wipe seems to only affect Samsung devices. Both Google
and Samsung already have patches and are working with vendors and
network operators to push them out to users.
