TOP VULNERABILITY THIS WEEK: The US House of Representatives

Intelligence Commitee urged American companies on Monday to stop doing
business with Huawei Technologies and ZTE Corp citing fears that China
could use their equipment to engage in espionage.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Huawei and ZTE labeled cyberthreats by US House of
Representatives Intelligence Commitee
Description: The US House of Representatives’ Intelligence Commitee
urged American companies on Monday to stop doing business with Huawei
Technologies and ZTE Corp citing fears that China could use their
equipment to engage in espionage. China has called the accusations
baseless and said that that the report “is merely based on subjective
conjecture and untrue foundations.”

Back in 2008, Huawei’s attempt to buy a major stake in 3Com Corp. was
blocked by the US government citing security concerns. Huawei is one of
the largest telecom gear suppliers in the world.

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 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. 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: Even more attacks against US banks
Description: According to security firm RSA and based on their analysis
of “underground chatter”, an international group of cybercriminals is
plotting a campaign to steal money from online accounts of thousands of
consumers at over 30 major U.S. banks. The gang is allegedly in process
of recruiting 100 botmasters who would each be responsible for the
control of bots similar to the Trojan “Gozi”. Each botmasters will be
financially backed by an investor in order to acquire the hardware and
software necessary to conduct the attacks. This could end up being the
largest coordinated attack on U.S. financial institutions to date.
