Imperva, a Data Security firm, announced today the release of study analyzing 32 million passwords recently exposed in the Rockyou.com breach. Imperva’s Application Defense Center (ADC) analyzed the strength of the passwords in a report, Consumer Password Worst Practices, that analyzes 32 million passwords to help consumers and website administrators identify the most commonly used passwords they should avoid when using social networking or e-commerce sites.

The report identifies the most commonly used passwords:
In a statement issued yesterday, the German Federal Office for Security in Information Technology recommends that all Internet Explorer users switch to an alternative browser. They may resume using Explorer after a fix is issued by Microsoft for a critical vulnerability that has been implicated in the Chinese cyber attack against Google.
Affected are the versions 6, 7 to 8 Internet Explorer on Windows systems XP, Vista and Windows 7 Microsoft has released a security advisory in which it discusses ways of minimizing risk and is already working on a patch to close the security gap. The BSI expects that this vulnerability will be used in a short time for attacks on the Internet.
According to the statement from BSI, even running Internet Explorer in “protected” mode is not enough to prevent a hacker from exploiting this security flaw.
Researchers of the Cryptology and Information Security group of the Centrum Wiskunde & Informatica (CWI) in Amsterdam with partners from Germany (BSI and Bonn University), France (INRIA Nancy), Japan (NTT) and Switzerland (EPFL) have broken a 768-bit RSA key by finding its prime factors. This new record demonstrates the vulnerability of 768-bit RSA keys.
The first 512-bit RSA key was broken in 1999, in 2005 followed by the first 663-bit key. Extrapolating this trend, it is reasonable to expect that 1024-bit keys will exhibit a similar degree of vulnerability within the next decade as 768-bit keys do now.
The 768-bit factored key is an integer of 232 digits. During a timeframe of 2.5 years many thousands of CPUs on a large number of different locations were deployed to break this key. The total amount of computing power used is equivalent to 1700 2.2 GHz CPUs during one year.

The latest «State of the Internet 2009» report issued by CA, Inc. profiles the top online threats from 2009. The study, based on data compiled by CA’s Global Security Advisor researchers, found that rogue security software, search index poisoning, social networks and cybersquatting were among the most notable online threats of 2009.
CA security researchers also offer predictions for the top Internet threats for 2010, including an increase in “malvertising” and the potential for another big computer worm outbreak like Conficker.
