Insights on how to reduce noise in AWS Access Analyser

Review

Recently I read an interesting article:

https://aws.amazon.com/blogs/security/how-to-prioritize-iam-access-analyzer-findings/

Well, I don’t expect it to be interesting for most of people.

But for people that are in charge of security reviews of company AWS accounts and review AWS Access Analyser - it makes life much simpler.

Basically it shows a way to mute repeated false postitives. For example when you use SSO all new SSO users will be shown in AWS Access Analyser - that probably not a good thing. Especially if you have a lot of those.

Then you can just go to Archive rules - and auto archive SSO users :)

More details are in the article.

Review of Fake ransomware article

Review

Recently I read an interesting article on fake ransomware:

Fake ransomware gang targets U.S. orgs with empty data leak threats: https://www.bleepingcomputer.com/news/security/fake-ransomware-gang-targets-us-orgs-with-empty-data-leak-threats/

That was quite fascinating insight in social engineering in cyber crime world: that fake ransomware is quite widespread and popular.

Why work hard on hacking somebody servers if you can just claim that you stole the data and demand the ransom? :)

Surprisingly effective tactic. So to say - lean approach in the world of ransomware gangs.

Review of Design your life for happiness with Elizabeth Dunn

Review

Recently I listened to an interesting TED talk:

https://www.ted.com/talks/the_ted_interview_design_your_life_for_happiness_with_elizabeth_dunn

That was quite interesting insight in happiness causes. It seems that we are wired to be happy when we share, when we give, when we help each other.

Other insights:

  • people that buy time with money are usually happier
  • people who don’t use their smartphone during together meal are happier

One more brick to the happiness in life :)

Review of TED talk about AI LLM being smart and stupid

Review

Recently I listened to an interesting TED talk suggested by our CEO:

https://www.ted.com/talks/yejin_choi_why_ai_is_incredibly_smart_and_shockingly_stupid

That was quite interesting insight in strength and weaknesses of AI LLM like ChatGPT.

  • Large Language Models(LLM) training date is huge but reasoning is still quite weak.
  • LLM sustainability is an open question
  • LLM think what next word to say, not what to say.
    • And that’s why they hallucinate.
  • Even before watching this talk I got impression of LLM as super/very hardworking and at the same time very low intelligence system.
  • AI Scientist in a talk tells that we should work on more intelligent models, idea is replace quantity with quality have a lot of downsides.
  • So LLM is not something to fear, it’s something to stay and be useful. But we can do much better AI systems in future :)

How to add showcmd to spacevim

How to display commands that you type in Normal mode in statusbar

As a novice in vim I would like to visually see which command I’m typing when I use VIM.
It appears not so straightforward in SpaceVIM as it already have pretty much magic around configuration.
When I wrote this documentation I used spacevim version 2.1.0 and neovim version 0.9.
