How an Obscure Company Took Down Big Chunks of the Internet

Posted by in category: internet

Early Tuesday morning, large portions of the web sputtered out for about an hour. The downed sites shared no obvious theme or geography; the outages were global, and they hit everything from Reddit to Spotify to The New York Times. (And yes, also WIRED.) In fact, the only thing they have in common is Fastly, a content-delivery network (CDN) provider whose predawn hiccup reverberated across the internet.

You may not have heard of Fastly, but you likely interact with it in some fashion every time you go online. Along with Cloudflare and Akamai, it’s one of the biggest CDN providers in the world. And while Fastly has been vague about what specific glitch caused Tuesday’s worldwide disruptions, the incident offers a stark reminder of how fragile and interconnected internet infrastructure can be, especially when so much of it hinges on a handful of companies that operate largely outside of public awareness.

Humans Can Learn How to ‘Echolocate’ in Just 10 Weeks, Experiment Shows

Echolocation for humans. Original post https://journals.plos.org/plosone/article


With enough training, most humans can learn how to echolocate, using their tongue to make clicking sounds, and interpreting the sounds of the echoes that come back, reflected from the surrounding environment.

In as few as 10 weeks, researchers were able to teach participants how to navigate obstacles and recognize the size and orientation of objects using the rebounding calls of their clicks. The experiment involved 12 participants who’d been diagnosed as legally blind during their childhood, and 14 sighted people.

Windows Container Malware Targets Kubernetes Clusters

Posted by in category: cybercrime/malcode

“Siloscape”, the first malware to target Windows containers, breaks out of Kubernetes clusters to plant backdoors and raid nodes for credentials.

Windows containers have been victimized for over a year by the first known malware to target Windows containers. The ongoing campaign pierces Kubernetes clusters so as to plant backdoors, allowing attackers to steal data and user credentials, or even hijack an entire databases hosted in a cluster.

The malware was discovered by Unit 42 security researcher Daniel Prizmant. He dubbed it Siloscape, which he pronounces “Silo escape.” The malware pries open known vulnerabilities in web servers and databases so as to compromise Kubernetes nodes and to backdoor clusters.

Study links blood cell mutations to increased infection risk with age

Posted by in categories: biotech/medical, genetics

New research suggests age-related changes in blood cell chromosomes are a marker of impaired immunity.

A person’s risk of severe infections increases dramatically as they grow older, but scientists do not yet understand how age might be linked to weakened immunity. Now, research shows that certain age-related changes in are associated with a higher risk of a range of severe infections including severe COVID-19, other pneumonias, and sepsis.

Researchers analyzed genetic and clinical data from nearly 800000 patients from around the world. They discovered that people with a specific type of acquired rearrangement in the chromosomes of their cells, called mosaic chromosomal alterations (mCAs), were nearly three times more likely to develop sepsis and two times more likely to get pneumonia than those without mCAs. These genetic changes accumulate in blood cells with age and often indicate a common condition in the elderly called clonal hematopoiesis.
