U.S. CERT Issues Alert on DNS Amplification Attacks

Neil Schwartzman writes to report that U.S. Cert issued Alert TA13-088A on Friday March 29, 2013. "It is a solid how-to guide to test for, and remediate DNS configurations that can be used for Distributed Denial of Service attacks." more

Cryptography is Hard

In the debate about "exceptional access" to encrypted conversations, law enforcement says they need such access to prevent and solve crimes; cryptographers, on the other hand, keep saying it's too complicated to do safely. That claim is sometimes met with skepticism: what's so hard about encryption? After all, you learn someone's key and just start encrypting, right? I wish it were that simple - but it's not. more

Wow! BIND9 9.10 Is out, and What a List of Features!

Today the e-mail faerie brought news of the release of BIND9 9.10.0 which can be downloaded from here. BIND9 is the most popular name server on the Internet and has been ever since taking that title away from BIND8 which had a few years earlier taken it from BIND4. I used to work on BIND, and I founded ISC, the home of BIND, and even though I left ISC in July 2013 to launch a commercial security startup company, I remain a fan of both ISC and BIND. more

Online Drug Traffic and Registrar Policy

Last month I published an article called "What's Driving Spam and Domain Fraud? Illicit Drug Traffic" which explained how the many of the troublesome online crime issues are related to the online sale of narcotics and dodgy pharmaceuticals. Since this article was published we have witnessed one of the largest international law enforcement efforts against online drug traffic (Operation Pangea II)... more

Client-based WDS: Providing Application Acceleration in Mobile and VPN Environments

Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more

How Hard Is It to Deploy DKIM?

It's coming up on two years since the DomainKeys Identified Mail (DKIM) standard was published. While we're seeing a certain amount of signed mail from Google, Paypal, and ESPs, there's still a long way to go. How hard is it to sign your mail with DKIM? The major hurdle might seem to be getting mail software that can sign outgoing mail. more

Researches Demonstrate How IPv6 Attacks Can Bypass Network Intrusion Detection Systems

With the increasing popularity of IoT devices and the added interest of transition to IPv6, a whole new range of threat vectors are evolving that allow attackers to set up undetectable communications channels across networks. more

P2P as a New Spam Medium, Moving From PoC to Full Operations

Spam on P2P networks used to be mainly with advertising inside downloaded movies and pictures (mainly pornographic in nature), as well as by hiding viruses and other malware in downloaded warez and most any other file type (from zip archives to movie files). Further, P2P networks were in the past used for harvesting by spammers. Today, P2P has become a direct to customer spamvertizing medium. This has been an ongoing change for a while. As we speak, it is moving from a proof of concept trial to a full spread of spam, day in, day out... more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

RIPE NCC Publishes Case Study of youtube.com Hijack

As you may be aware from recent news reports, traffic to the youtube.com website was 'hijacked' on a global scale on Sunday, 24 February 2008.
