*** Cisco Unified Computing System E-Series Blade Servers Cisco Integrated Management Controller SSH Denial of Service Vulnerability ***
---------------------------------------------
A vulnerability in the Cisco Integrated Management Controller (Cisco IMC) SSH module of the Cisco Unified Computing System E-Series Blade servers could allow an unauthenticated, remote attacker to cause a denial of service condition.
The vulnerability is due to a failure to properly handle a crafted SSH packet. An attacker could exploit this vulnerability by sending a crafted packet to the SSH server running on the Cisco IMC of an affected device, which could result in the Cisco IMC becoming unresponsive. The operating system running on the blade will be unaffected.

*** Why Google Is Pushing For a Web Free of SHA-1 ***
---------------------------------------------
An anonymous reader writes: Google recently announced Chrome will be gradually phasing out support for certificates using SHA-1 encryption. They said, "We need to ensure that by the time an attack against SHA-1 is demonstrated publicly, the web has already moved away from it." Developer Eric Mill has written up a post explaining why SHA-1 is dangerously weak, and why moving browsers away from acceptance of SHA-1 is a lengthy, but important process.

*** 'Google Dorking' - Waking Up Web Admins Everywhere ***
---------------------------------------------
Last July, the US Department of Homeland Security warned of a new kind of criminal attack: 'Google dorking'. This refers to asking Google for things they have found via special search operators.

*** How a DNS Sinkhole Can Protect Against Malware ***
---------------------------------------------
The Domain Name Service (DNS) is an integral part of Internet access. It translates human-recognized domain names into computer-readable IP addresses in order to facilitate online communication and connection between devices. ... And one of the best ways to gain control is via DNS itself, in order to disrupt malware transmission at the very point of connection. A DNS sinkhole, or sinkhole server, gives organizations this control in order to prevent internal access to malicious websites.

*** Threat Spotlight: 'Kyle and Stan' Malvertising Network Threatens Windows and Mac Users With Mutating Malware ***
---------------------------------------------
Once the victim gets redirected to the final URL, the website automatically starts the download of a unique piece of malware for every user. The file is a bundle of legitimate software, like a media-player, and compiles malware and a unique-to-every-user configuration into the downloaded file. The attackers are purely relying on social engineering techniques, in order to get the user to install the software package. No drive-by exploits are being used thus far.

*** Modern anti-spam and E2E crypto ***
---------------------------------------------
... asked me to write up some thoughts on how spam filtering and fully end to end crypto would interact, so its all available in one message instead of scattered over other threads. Specifically he asked for brain dumps on: - how does antispam currently work at large email providers - how would widespread E2E crypto affect this - what are the options for moving things to the client (and pros, cons) - is this feasible for email?

*** Research Finds No Large Scale Heartbleed Exploit Attempts Before Vulnerability Disclosure ***
---------------------------------------------
In the days and weeks following the public disclosure of the OpenSSL Heartbleed vulnerability in April, security researchers and others wondered aloud whether there were some organizations - perhaps the NSA - that had known about the bug for some time and had been using it for targeted attacks. A definitive answer to that question may never come, but ...
