Google, Yahoo tighten spam filtering

Google and Yahoo are expanding their use of a successful system for identifying spam.The move is part of years-long effort to implement a series of checks designed to figure out if an email really has been sent by the domain it purports to come from.Email spoofing has long been a problem since its easy to forge the "from" address, making it more likely the receiver will believe it came from a legitimate source.By Nov. 2, Yahoo plans to being using DMARC (Domain-based Message Authentication, Reporting & Conformance) for its ymail.com and rocketmail.com services. Next year, Google also plans to move Gmail to a strict DMARC policy, according to a news release.To read this article in full or to leave a comment, please click here

6WIND Offering Accelerated L3 Virtual Appliances

6WIND, a Packet Pushers sponsor, has been helping get the most networking performance from x86 hardware, making the acceleration software that other companies could use to make the most of their standard servers with multi-core CPUs and Linux. 6WIND has recently taken a further step, offering its own VNFs and virtual networking acceleration software packages to end users like you and me. For example, the Turbo Router and Turbo IPSEC appliances compete with virtual routers from Cisco and Brocade. 6WIND will be appearing on the Packet Pushers Priority Queue podcast near the end of October 2015.

Magento says compromised sites haven’t patched older vulnerabilities

Magento said Tuesday there does not appear to be a new vulnerability in its e-commerce platform that is causing some websites to become infected with the Neutrino exploit kit. Some of the affected websites appear to not have patched a code execution vulnerability nicknamed the Shoplift Bug Patch, Magento's security team wrote in a blog post. A patch was released in February. Other Magento-powered sites have not applied other patches, making them vulnerable. The latest attack against Magento was highlighted by Malwarebytes and Sucuri, two security companies, who noticed attacks on the client and server sides.To read this article in full or to leave a comment, please click here

DNSSEC is Open for Beta

DNSSEC logo

Since January, CloudFlare has been running a small, private beta for DNSSEC. Starting today, the DNSSEC beta is open for everyone. To request access, email [email protected].

A Background on DNS and DNSSEC

DNS is the system that lets your browser know which web server to connect to when you request to visit a website. It’s the underlying backbone of the usable internet, and yet, is vulnerable to man in the middle attacks.

In DNS, an attacker sitting in the middle of your connection to the internet can tell your browser to connect to any web server they’d like. Browsers trust any DNS records they receive as a response to a DNS query, because DNS, invented in 1983 before the public consumption of the Internet, does not perform any authentication.

There is a solution. It’s called DNSSEC and it adds cryptographic hashes and signatures for authenticating DNS records. You can read more about DNSSEC and how it works in a previous blog post.

The DNSSEC beta is open to all websites that use CloudFlare for DNS. If you want to be a part of our beta and be one of the first CloudFlare websites with DNSSEC, email us for beta Continue reading

Dell targets hyperscale wannabes with new line of bare-bones servers

Dell has released a new family of servers aimed at companies that want some of the cost savings of using custom-built hardware but without having to do as much of the engineering work.The servers are aimed at what Dell calls the second tier of hyper-scale customers -- those big enough to buy hundreds or even thousands of servers at a time, but who aren't as massive as a Google or a Facebook. That includes smaller Web-scale companies as well as telcos, financial services firms, cloud software companies and others.The Googles of the world design their own hardware to make it as energy- and space-efficient as possible. That means stripping out management software and redundant components, and building resiliency into their software stack rather than the hardware itself.To read this article in full or to leave a comment, please click here

Western Digital self-encrypting external hard disk drives have flaws that can expose data

The hardware-based encryption built into popular Western Digital external hard disk drives has flaws that could allow attackers to recover data without knowing the user password.A team of three security researchers investigated how the self-encryption feature was implemented in several popular Western Digital My Passport and My Book models. Depending on the type of microchip used for the encryption operation, they found design flaws and backdoor-like features that enable brute-force password guessing attacks or even decryption of the data without knowing the password.In some cases they found that the encryption is performed by the chip that bridges the USB and SATA interfaces. In other cases the encryption is done by the HDD's own SATA controller, with the USB bridge handling only the password validation.To read this article in full or to leave a comment, please click here
