Charting the Course For Aruba

By now you’ve seen the news that longtime CEO of Aruba Keerti Melkote is retiring. He’s decided that his 20-year journey has come to a conclusion and he is stepping down into an advisory role until the end of the HPE fiscal year on October 31, 2021. Leaving along with him are CTO Partha Narasimhan and Chief Architect Pradeep Iyer. It’s a big shift in the way that things will be done going forward for Aruba. There are already plenty of hot takes out there about how this is going to be good or bad for Aruba and for HPE depending on which source you want to read. Because I just couldn’t resist I’m going to take a stab at it too.

Happy Trails To You

Keerti is a great person. He’s smart and capable and has always surrounded himself with good people as well. The HPE acquisition honestly couldn’t have gone any better for him and his team. The term “reverse acquisition” gets used a lot and I think this is one of the few positive examples of it. Aruba became the networking division of HPE. They rebuilt the husk that was HP’s campus networking division and expanded it Continue reading

Supermicro launches liquid cooling initiative

Super Micro Computer, a.k.a. Supermicro, is adding a range of liquid cooling solutions to its server products. Working with customers, Supermicro will design, implement and test the latest liquid cooling technologies at the rack level. Customers who implement liquid cooling can improve data center PUE (power usage effectiveness) and TCO by more than 40% by cutting power costs, the company says.The cooling is for new systems coming to market. Like most OEMs that support liquid cooling, Supermicro isn’t recommending retrofits to existing installations. It cites two reasons: One, it would be expensive, as you’d have to drill into the rack and server chassis to make room for the cooling piping. And two, the entire rack or cluster would have to be inactive while the retrofit was being done, and most firms won’t tolerate that.To read this article in full, please click here

Experimental Morpheus CPU is ‘mind-bogglingly terrible’ to crack

To many of us, Morpheus is a character played by Laurence Fishburne in The Matrix movies. To others, Morpheus is the Greek god of sleep and dreams. To others still, Morpheus is a digital synthesizer from the early ‘90s that developed a cult following.The Morpheus we’re discussing today, however, is of far greater relevance to enterprise IT professionals who constantly are searching for ways to protect their networks from the ever-present threat of hackers.Developed by a team at the University of Michigan, this Morpheus is a CPU that ingeniously protects against hacking attempts by using encryption that changes every few milliseconds, which prevents intruders from getting a fix on how a system is set up. This makes cracking the encryption nearly impossible and is sure to drive hackers crazy.To read this article in full, please click here

Syria’s exam-related Internet shutdowns

Syria’s exam-related Internet shutdowns

To prevent cheating in exams many countries restrict or even shut down Internet access during critical exam hours. For most of June Syria is having planned Internet shutdowns during critical exam periods. The exam schedule is as follows:

Syria’s exam-related Internet shutdowns

I’m grateful to a Twitter user for the translation from the original Arabic and collating the data.

Cloudflare Radar allows anyone to track Internet traffic patterns around the world, and it has country-specific pages. The chart for the last seven days of Internet use in Syria as seen by Cloudflare shows two drops to almost zero corresponding to the first two exams on the schedule.

Syria’s exam-related Internet shutdowns

The Internet outage starts at around 0100 UTC (0400 local time) and ends about four and a half hours later at 0530 UTC (0830 UTC). This covers the period before the exams start apparently to prevent any figuring out the answers.

If you want to follow the other outages for the remaining seven exams you can see live data on the Cloudflare Radar Syria page.

Don’t Be Fooled by Agent Tesla’s Football Club Red Herring

Contributors: Subrat Sarkar (T-Rex), Jason Zhang (NSBU TAU)

Agent Tesla is a remote access tool (RAT) that is known for stealing credentials from several applications, including web browsers, VPN clients, and mail and FTP applications. It also supports keylogging, screen grabbing, and other functionality. Since it first came on to the scene in 2014, Agent Tesla has evolved into a fully customizable commercial malware tool, which is readily available on underground markets. Given the huge popularity of the malware, this threat has been thoroughly covered by the threat intelligence community, including our analysis in 2018 [1], our reports on COVID-19 related cyber threats [2] [3], and a recent article describing a surge of infections [4]. More recently, we detected a new wave of Agent Tesla attacks that exhibited some interesting characteristics, such as requesting a connection to top European football club websites.

In this blog post, we first present some of VMware’s NSX Advanced Threat Prevention telemetry and email metadata from the attack. We then provide our analysis detailing the most distinctive aspects of the attack, from the use of well-known European football club websites to key tactics, techniques, and procedures (TTPs).

The Hedge 86: TCPLS

TCP and QUIC are the two primary transport protocols in use on the Internet today—QUIC carries a large part of the HTTP traffic that makes the web work, while TCP carries most everything else that expects reliability. Why can’t we apply the lessons from QUIC to TCP so we can merge these two protocols, unifying Internet transport? TCPLS is just such an attempt at merging the most widely used reliable transport protocols.

Separating Compute And Storage In Hyperconverged Infrastructure
