Researchers Can Generate RSA SecurID Random Numbers Flawlessly
Fluffeh writes "A researcher has found and published a way to tune into an RSA SecurID Token. Once a few easy steps are followed, anyone can generate the exact numbers shown on the token. The method relies on finding the seed that is used to generate the numbers in a way that seems random. Once it is known, it can be used to generate the exact numbers displayed on the targeted Token. The technique, described on Thursday by a senior security analyst at a firm called SensePost, has important implications for the safekeeping of the tokens. An estimated 40 million people use these to access confidential data belonging to government agencies, military contractors, and corporations. Scrutiny of the widely used two-factor authentication system has grown since last year, when RSA revealed that intruders on its networks stole sensitive SecurID information that could be used to reduce its security. Defense contractor Lockheed Martin later confirmed that a separate attack on its systems was aided by the theft of the RSA data." -
Cache On Delivery — Memcached Opens an Accidental Security Hole
jamie spotted this eye-opening presentation (here's a longer explanation) about how easy it is to access sensitive data on many sites using memcached, writing "If you already know what memcached is, skim to slide #17. The jaw-drop will happen around slide #33. Turns out many websites expose their totally-non-protected memcached interface to the Internet, including gowalla, bit.ly, and PBS."
