#Zoomposium with Prof. Dr. #Arieh #Ben-#Naim: “Demystifying #Entropy

Information about the person and his scientific work

In another installment of our “Zoomposium series” on the topic of #physics and its #limits, my colleague Axel Stöcker from the “Blog der großen Fragen” and I had the opportunity to interview the renowned Israeli physical chemist Prof. Dr. Arieh Ben-Naim on the exciting topic of “Demystifying Entropy”.

Arieh, who was born on July 11, 1934, held a chair in #Physical #Chemistry at the Hebrew University of Jerusalem for over 40 years, with his main field of research being the theory of the #structure of #water, aqueous solutions and hydrophobic-hydrophilic interactions. He was mainly concerned with theoretical and experimental aspects of the general theory of #liquids and #solutions. In recent years, he has advocated the use of #information theory to better understand and advance #statistical #mechanics and #thermodynamics.

In this context, he has also worked intensively on the question of the nature and underlying principle of the phenomenon of #entropy, which he has published in numerous often cited but also controversially discussed popular science books.

The basic tenor of all his publications and lectures is that we need a new basic understanding of the phenomenon of entropy. In Arieh's view, entropy, which originally stems from the laws of #thermodynamics and in particular the 2nd law, has been misused and incorrectly transferred as a #concept to other areas of #physics, #biology and everyday #life.

In this respect, it was finally time (bon mot) to ask the author himself about his ground-breaking theses, which cast a different light on the #phenomenon of entropy or perhaps better said, bring entropy back to its place of origin.

The interview we conducted with him is in English.

My computer is dying. Heat problem. A fan is failing.
 The part is discontinued. the laptop is only 5 years old. Having trouble finding the exact part# for the fan assembly even on like Ebay and Amazon and Alibaba. Can't afford new computer. Need new glasses too. Can't afford them either. can't afford my insurance premiums either. might just cash in my IRA. It's tanking with the stock market anyway.

It struck me this morning that money is like energy, and like energy you can inject more of it into a system to lower the total entropy of the system, but without it the entropy just keeps increasing. Conversely as DOG(e)(gy) sucks money out of the US system, the entropy is increasing at a really fast rate, and goddess knows where the chaos will lead us.

anyway. this text is from my Patreon. I usually post art i'm working on, not just thoughts about the sorry state off my finances. but anyway if you want to join please do. there's a free option, even.

MalChela Updates: New Features and Enhancements

It’s been just over a week since MalChela was initially released and already here have been a number of updates.

mStrings

In the previous post, I walked through the new mStrings function. I think this is one of my favorites so far. It extracts strings from a file and uses Sigma rules defined in YAML against the strings to evaluate threats and align results to the MITRE ATT&CK framework.

For fun I pointed it at an old WannaCry sample . I had a proud papa moment at the positive network IOC detection.

Check for Updates

Next came a function to automatically check the GitHub repo for updates and encourage a git pull to grab the latest… because apparently I can’t stop myself and this project will just keep growing, as my sleep keeps dwindling. Personally I found it ironic that you have to update in order to get the update telling you that updates are available… but it will work for all future updates as they come. So go ahead and update why don’t you.

New File Analyzer module

Most recently a File Analyzer module has been added. Give it the path to your suspect file and it will return back:

  • SHA-256 Hash
  • Entropy (<7.5=high)
  • A RegEx detection for packing (mileage may vary)
  • PE Header info if it’s a PE
  • File Metadata
  • Yara Matches (any rules in yara_rules folder in workspace)
  • If there’s a positive match for the hash on VirusTotal (leverages the same key as previously in MalChela with the Virus Total / Malware Bazaar lookup)

Lastly, you’re given the option of whether or not you want to run strings on the file, or return to the main menu.

I really like the idea of using this as a possible first step in static analysis. Run this first and opt for strings. Things look interesting there, throw it into mStrings. Positive match on VirusTotal – use the malware hash lookup and get a more detailed analysis. Use the results from mStrings to craft a YARA rule and add it to your repo for future detections.

#DFIR#Entropy#Hash

"Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world than a reflection of our growing ignorance. Embracing that truth is leading to a rethink of everything from rational decision-making to the limits of machines."
