Computer-Related Neck Pains? Try an Acupressure Pillow

Do you ever get neck pains after sitting in front of the computer for too long? If so, you’re not alone. According to a recent study, nearly two-thirds of Americans experience some form of neck pain each year. And with the average person spending over eight hours a day staring at a screen, it’s no wonder that so many of us are suffering.

But there is some good news. If you’re looking for a way to relieve your computer-related neck pain, you may want to try an acupressure pillow. Acupressure is an ancient Chinese healing practice that involves applying pressure to specific points on the body. And according to Traditional Chinese Medicine, there are certain points on the neck that can help relieve pain.

The best part about acupressure is that it’s completely safe and there are no side effects. So if you’re looking for a natural way to ease your neck pain, an acupressure pillow may be just what you need. 

Symptoms of Computer-Related Neck Pain

There are a few different symptoms that are associated with computer-related neck pain. If you’re experiencing any of the following, it may be time to try an acupressure pillow:

Mantis – the most powerful botnet to date

Mantis - the most powerful botnet to date
Mantis - the most powerful botnet to date

In June 2022, we reported on the largest HTTPS DDoS attack that we’ve ever mitigated — a 26 million request per second attack - the largest attack on record. Our systems automatically detected and mitigated this attack and many more. Since then, we have been tracking this botnet, which we’ve called “Mantis”, and the attacks it has launched against almost a thousand Cloudflare customers.

Cloudflare WAF/CDN customers are protected against HTTP DDoS attacks including Mantis attacks. Please refer to the bottom of this blog for additional guidance on how to best protect your Internet properties against DDoS attacks.

Have you met Mantis?

We named the botnet that launched the 26M rps (requests per second) DDoS attack "Mantis" as it is also like the Mantis shrimp, small but very powerful. Mantis shrimps, also known as “thumb-splitters”, are very small; less than 10 cm in length, but their claws are so powerful that they can generate a shock wave with a force of 1,500 Newtons at speeds of 83 km/h from a standing start. Similarly, the Mantis botnet operates a small fleet of approximately 5,000 bots, but with them can generate a massive force — responsible for the largest Continue reading

8 enterprise storage trends to watch

The data storage industry is experiencing a major transformation driven by multiple factors, including the need for security, speed, efficiency, and lower costs. IT research firm Gartner recently predicted 23-times growth in shipped petabytes through 2030, a trajectory that promises to radically reshape and redefine current data center and IT operations. To stay on top of the storage game, keep a close eye on these eight trends.1. DNA storage DNA, when used as a data storage medium, promises a far higher capacity and more resilient storage environment than traditional storage architecture. DNA storage allows molecular-level data storage, archiving information directly into DNA molecules.To read this article in full, please click here

Hedge 138: The Robustness Principle

Most network engineers take it as a “given” that the robustness principle is the “right way” to build protocols and networks—”be conservative in what you send, and liberal in what you receive.” The idea behind the robustness principle is that implementations should implement specifications as accurately as possible, but they should also accept malformed and otherwise erroneous data, process the best they can, and drop the bits they cannot process. This should allow the network to operate correctly in the face of defects and other failures. A recent draft, draft-iab-protocol-maintenance/, challenges the assumptions behind the robustness principle. Join Tom and Russ as they discuss the robustness principle and its potential problems.

OpenSSL Heap Memory Corruption Vulnerability Fixed

Ever since CVE-2022-2274, didn’t reach Heartbleed levels of ick, but it was more than bad enough. What happened was that the OpenSSL 3.0.4 release introduced a serious RSA bug in X86-64 CPUs supporting the AVX512 IFMA instructions. This set of CPU single instruction, multiple data (SIMD) instructions for floating-point operations per second (FLOPS) was introduced in 2018. You’ll find it in pretty much every serious Intel processor, from Skylake to AMD’s forthcoming Zen 4. In other words, it’s probably in every server you’re currently running. Is that great news or what? Memory Corruption The problem is that RSA 2048-bit private key implementations fail on this chip architecture. Adding insult to injury, memory corruption results during the computation. The last straw? An attacker can use this memory corruption to trigger a remote code execution (RCE) on the machine. Exploiting it might not be easy, but it is doable. And, even if an attack isn’t that reliable, if it’s used to hit a server that constantly respawns, say a web server, it Continue reading
