Setting up my macOs development environment for 2022

By the third or fourth week of November was the only time I realized I was hacked. Tinkering on my mac’s logs and system files showed that the attackers started observing what I was doing between the last week of Febrary to the first week of March. Ill try to write all four exploits that the attackers did in a different blog post. In the meantime, this article details the custom “hack” I set on my mac for additional protection. This may or may not work for everyone. Duplicate at yer own risk.

Things I did:

• Install XCode and CLI tools
• Deactivate remote management sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -deactivate -stop
• Remove Desktop Sharing sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -deactivate -configure -access -off
• Remove Apple Remote Desktop Settings

sudo rm -rf /var/db/RemoteManagement ; \
sudo defaults delete /Library/Preferences/com.apple.RemoteDesktop.plist ; \
defaults delete ~/Library/Preferences/com.apple.RemoteDesktop.plist ; \
sudo rm -r /Library/Application\ Support/Apple/Remote\ Desktop/ ; \

No VSCode, right? I decided to use GitHub codespaces instead of coding in my Mac. I’ll most-likely write another article to talk about my GitHub codespaces set-up. Cheers!
