Apple knows how to sell stuff. You buy watches for $500, it has annoying metallic clip which scratches your laptop. You buy a clipless band for additional $100.

OMG C# is the best! Since C# 8.0 you can write ``` using var file = new System.IO.StreamWriter("myFile.txt"); // code ``` Instead of ``` using (var file = new System.IO.StreamWriter("myFile.txt")) { // code } ``` No crazy nesting anymore ❤️

This article isn't about typosquatting or benign "malicious" modules. It's about disclosing the underlying security research and its findings. A really great write-up by Kirill Efimov (@byte89) and the work done by @snyksec's security research team

A short time ago, we started supporting C/CPP here at @snyksec :) 🦮 So we created a non-intimidating introductory to C/CPP vulnerabilities and exploitation (while using a lot of Harry Potter refs UwU) Check it out! snyk.io/blog/unintimid… @snyksec

My writeup on visibly invisible malicious npm packages is out! I invite you to (not 👹) see how such an attack can compromise your systems (and yes - your devs are targeted first) @snyksec snyk.io/blog/visibly-i…
