Piercing a key selling point of commercial cloud computing services, computer scientists have devised a hack that allows an attacker using Amazon's EC2 platform to steal the secret cryptographic keys of other users. . The proof-of-concept attack is significant because Amazon Web Services and many other cloud service providers already blocked a previous key-recovery attack on co-located virtual machines that was unveiled in 2009. The paper was one of the first to highlight the security risks that come when someone uses the same physical piece of hardware as an advanced attacker. Cloud providers and makers of cryptography and virtual-machine software patched many of the weaknesses that made the attack possible. As a result, many of the techniques that gave the 2009 attack a high degree of accuracy are no longer possible. .

Researchers have warned of a vulnerability present on an estimated 10 percent of Android phones that may allow attackers to obtain highly sensitive credentials, including cryptographic keys for some banking services and virtual private networks, and PINs or patterns used to unlock vulnerable devices.. The vulnerability resides in the Android KeyStore, a highly sensitive region of the Google-made operating system dedicated to storing cryptographic keys and similar credentials, according to an advisory published this week by IBM security researchers. By exploiting the bug, attackers can execute malicious code that leaks keys used by banking and other sensitive apps, virtual private network services, and the PIN or finger patterns used to unlock handsets..

When Kaspersky Lab last week spotted code-signed Trojan malware dubbed Mediyes that had been signed with a digital certificate owned by Swiss firm Conpavi AG and issued by Symantec, it touched off a hunt to determine the source of the problem. . The answer, says Symantec's website security services (based on the VeriSign certificate and authentication services acquisition), is that somehow the private encryption key associated with Conpavi AG certificate had been stolen. The link for this article located at Network World is no longer available. .
