The BEAST attack on some TLS implementations made major news when it was disclosed, showing that attackers could intercept and decrypt SSL-protected sessions in real time, breaking a significant portion of the confidentiality model of the protocol. Vendors rushed to patch and implement mitigations. That was in 2011. Nearly three years later, Siemens is pushing […]

Google has patched a long list of serious security vulnerabilities in Chrome, including at least 19 highly rated flaws. The company patched a total of 31 vulnerabilities in Chrome 34 and paid out more than $28,000 in rewards to researchers who reported bugs to Google.
