The Black Energy malware family has a long and storied history dating back to 2007. Originally a monolithic DDoS platform, significant advancements were made in 2010 including support for an extensible plugin architecture that allowed Black Energy 2 to more easily expand beyond DDoS into other activities such as info-stealing, web-based banking attacks, spamming, etc.
This report examines, in-depth, a new Black Energy 2 plugin (ntp.dll) that allows “BE2” botnets to launch true distributed NTP reflection/amplification attacks. This is significant for a couple of reasons:
In detailing the relatively impressive technical implementation of this new BE2 DDoS attack plugin, this report provides some excellent general networking insights, an understanding of what it takes to really pull off a reflection/amplification attack on the Windows platform, and a somewhat humorous look at some prior attempts by other malware Continue reading

I’m facing a mini scaling challenge with Cisco SPAN (Switched Port ANalyzer) session and thought it would be good to share it with you fine folk. SPAN Challenge A 3750X switch is currently SPAN-ing a 10Gbps interface to a 1Gbps egress port. A … Continue reading

The idea for this post came from someone I was working with recently. Thanks Fan (and Carson, and Shree) :-)
In Service Software Upgrade (ISSU) is a method of upgrading software on a switch without interrupting the flow of traffic through the switch. The conditions for successfully completing an ISSU are usually pretty strict and if you don't comply, the hitless upgrade can all of a sudden become impacting.
The conditions for ISSU on the Nexus 5000 are pretty well documented (cisco.com link) however, there are a couple bits of knowledge that are not. This post is a reminder of the ISSU conditions you need to comply with and a call out to the bits of information that aren't so well documented.

When AMP (Accelerated Mobile Pages) was first announced it was right inline with Google’s long standing project to make the web faster. Nothing seemingly out of the ordinary.
Then I listened to a great interview on This Week in Google with Richard Gingras, Head of News at Google, that made it clear AMP is more than just another forward looking initiative from Google. Much more.
What is AMP? AMP is two things. AMP is a restricted subset of HTML designed to make the web fast on mobile devices. AMP is also a strategy to counter an existential threat to Google: the mobile web is in trouble and if the mobile web is in trouble then Google is in trouble.
In the interview Richard says (approximately):
The alternative [to a strong vibrant community around AMP] is devastating. We don’t want to see a decline in the viability of the mobile web. We don’t want to see poor experiences on the mobile web propel users into proprietary platforms.
This point, or something very like it, is repeated many times during the interview. With ad blocker usage on the rise there’s a palpable sense of urgency to do something. So Google stepped Continue reading
