A way to install Alpine Linux on a Scaleway Stardust instance without the use of a rescue image, but by booting into the install image over the network using https://netboot.xyz.

1. Connect to the serial console, using scw instance server console {uuid} zone={zone}

2. Reboot the VM into UEFI settings

   • either by executing systemctl reboot --firmware on the machine
   • or by using scw instance server reboot {uuid} zone={zone} locally and repeatedly mashing the escape key on the serial console

3. Go to Device Manager -> Network Device List -> the only network device -> HTTP Boot Configuration -> Boot URI

log4j RCE Exploitation Detection

You can use these commands and rules to search for exploitation attempts against log4j RCE vulnerability CVE-2021-44228

Grep / Zgrep

This command searches for exploitation attempts in uncompressed files in folder /var/log and all sub folders

sudo egrep -I -i -r '\$(\{|%7B)jndi:(ldap[s]?|rmi|dns|nis|iiop|corba|nds|http):/[^\n]+' /var/log

In most cases, the sudo command displays the error unable to initialize PAM: No such file or directory mostly appears when the pluggable authentication module file /etc/pam.d/sudo has been edited with a typo or an incorrect PAM module.

Via Single-User-Mode > Terminal

If you have an older Mac, you can boot into single-user mode, which allows you to access the command line mode of macOS directly, bypassing the UI.

• Press and hold down the COMMAND + S keys until you see commands being executed in the Terminal.

• Open the sudo file with vi /Volumes/Macintosh\ - Data/etc/pam.d/, fix what's wrong, save and close the file by switching from INSERT to the COMMAND mode with the ESC key, type :wq!, and hit enter.

Open in Visual Studio Code

• Open Automator
• Create a new document
• Select Quick Action
• Set “Service receives selected” to files or folders in any application
• Add a Run Shell Script action
  • your default shell should already be selected, otherwise use /bin/zsh for macOS 10.15 (”Catalina”) or later
  • older versions of macOS use /bin/bash
• if you're using something else, you probably know what to do 😉
