Fingerprints cloning in Samsung Galaxy S5

RSA conference is being held in San Francisco, where security researchers from FireEye revealed a security flaw related to the fingerprint sensor embedded in the Samsung Galaxy S5 and other smartphones running Android - allows cybercriminals to make duplicate user's fingerprints. According to Tao Wei and Yulong Zhang from FireEye, although mobile manufacturers have taken numerous steps to ensure the integrity and confidentiality of biometric systems, but still there is a possibility to clone users' fingerprint which can aid further attacks. This would give opportunity to hacker to get user-level access and run a program as root to steal information from the affected Android phones. In the case of Samsung Galaxy S5, all you need is to have system-level access. Android 5.0 Lollipop or above are unaffected to this issue.

LESS Admin rights result LESS Microsoft flaws

UK security firm Avecto states that if you want to mitigate critical vulnerabilities in Microsoft applications. All you need is just to remove admin rights from users. Exploitation requires admin privileges for almost 97% of Windows flaws; 99.5% of Internet Explorer and 95% of Office applications.
