From Inbox to Intrusion: Multi‑Stage Remcos RAT and C2‑Delivered Payloads in Network

This multi-stage fileless Remcos RAT attack leverages a phishing-delivered JavaScript dropper to trigger a reflective PowerShell loader that executes payloads entirely in memory. The infection chain utilizes obfuscation techniques like rotational XOR and Base64 encoding to reconstruct .NET payloads, significantly reducing the disk-based detection footprint. Stealth is maintained by using aspnet_compiler.exe as a LOLBin to proxy malicious execution and dynamically retrieving the final payload from a remote C2 server.

You Can Use Same Variable Name TWICE?!

🔥 NO WAY! Destructuring allows DUPLICATE variable names in the same statement! const {a, a} = obj is VALID JavaScript! Last one silently wins. ESLint doesn't catch this by default. Tag a dev who needs to see this!

Claude Code Unpacked : A visual guide (ccunpacked.dev)

#webdev #javascript #programming #claude #leak

Those of you who follow me for some time know that I have many creative fields I like and I change between them. So, one of them is game development.

Currently I re-create Super Mario Bros. 3 with the Phaser library in JavaScript. It's fun and I learn more about how Toshihiko Nakago coded Mario's movement.
With those game re-creations I improve the mechanics of my own games.

I know, you should stick to one theme to not confuse your followers. Do you would like me to stick to one area like generative art, drawing, gamedev or sculpting?
Please let me know in a reply.

🐦 When someone shares a link to Twitter…

– Reminds me to check my profile if cached tweets surfaced.

– Then I run `tweet-delete.js` script until it depletes the batch.

– Auto-clicks UI in a loop. Video attached of what it looks like.

For context, I used to have 13k+ followers on Twitter. Left when Musk took over.

Interestingly, I still have 9k followers. I assume others "voted with their feet" too.

Axios – niebezpieczny atak na łańcuch dostaw dużej biblioteki JavaScript

Ataki na łańcuch dostaw stały się codziennością krajobrazu rozwoju oprogramowania. Ostatnie incydenty takie jak atak na LiteLLM czy GlassWorm dobitnie potwierdzają tezę, że cykle wydawania oprogramowania potrafią być permanentnie zepsute. Sytuacji nie poprawia na razie fakt błyskawicznej adopcji generatywnej sztucznej inteligencji, w postaci dużych modeli językowych (ang. LLM), do tworzenia...
