This repo contains a cleanup script to remove the effects of the malware attack caused due to salt vulnerabilities on our platform. The CVEs for the vulnerabilities are:

• CVE-2020-11651
• CVE-2020-11652

• If you had iptables or ufw rules on the device, you need to manually add them back.
• Run cleanup.sh to undo the actions of the malware.
• Verify that /tmp/salt-minions and /var/tmp/salt-store have been removed.
• Verify that /var/spool/cron/crontabs/root does not have any unknown entries.
• Check memory usage by using free -mh or htop. If the memory usage is not reduced, please do a reboot.

If you have apparmor enabled, execute the following to disable it from running, just in case:

• profile salt-store /var/tmp/salt-store { }' | tee /etc/apparmor.d/salt-store
• apparmor_parser -r -W /etc/apparmor.d/salt-store

If you had selinux enabled, please enabled it by running:

    rm /etc/selinux/config
    echo SELINUX=enabled >/etc/selinux/config
    setenforce 1

The sa.txt is the script that was run by the malware. Unfortunately, it's not possible to automate the recovery entirely. Here are a couple of points you need to look for:

• Your docker images might be removed and your running containers could be stopped. You'll need to install them again.
• If you had any of the following packages, you will need to reinstall it:
  • aliyun
  • bcm-agent

Please contact [email protected] for any clarifications or help

P.S. If you see errors such as iptables not found or firewalld not found, please ignore it. It just tries and fails if it doesn't exits
