to the underlying host this can allow an adversary access to other containerized or virtualized resources from the host level or to the host itself in principle containerized virtualized resources should provide a clear separation of application functionality and be isolated from the host environment 1 there are multiple ways an adversary may escape from a container to a host environment examples include creating a container configured to mount the host s filesystem using the bind parameter which allows the adversary to drop payloads and execute control utilities such as cron on the host utilizing a privileged container to run commands or load a malicious kernel module on the underlying host or abusing system calls such as unshare and keyctl to escalate privileges and steal secrets 2 3 4 5 6 7 additionally an adversary may be able to exploit a compromised container with a mounted container management socket such as docker sock to break out of the container via a container administration command 5 adversaries may also escape via exploitation for privilege escalation such as exploiting vulnerabilities in global symbolic links in order to access the root directory of a host machine 8 in esxi environments an adversary may exploit a vulnerability in order to escape from a virtual machine into the hypervisor 9 gaining access to the host may provide the adversary with the opportunity to achieve follow on objectives such as establishing persistence moving laterally within the environment accessing other containers or virtual machines running on the host or setting up a command and control channel on the host id t1611 sub techniques no sub techniques ⓘ tactic privilege escalation ⓘ platforms containers esxi linux windows contributors alfredo

restricts certain system calls such as mount in kubernetes environments consider defining pod security standards that limit container access to host process namespaces the host network and the host file system 15 m1042 disable or remove feature or program remove unnecessary tools and software from containers m1038 execution prevention use read only containers read only file systems and minimal images when possible to prevent the running of commands 15 where possible also consider using application control and software restriction tools such as those provided by selinux to restrict access to files processes and system calls in containers 16 m1026 privileged account management ensure containers are not running as root by default and do not use unnecessary privileges or mounted components in kubernetes environments consider defining pod security standards that prevent pods from running privileged containers 15 m1051 update software ensure that hosts are kept up to date with security patches detection strategy id name analytic id analytic description det0219 detection strategy for escape to host an0612 detection of container escape attempts via bind mounts privileged containers or abuse of docker sock defenders may observe anomalous volume mount configurations e g hostpath to or proc unexpected privileged container launches or use of container administration commands to access host resources these events typically correlate with subsequent process execution on the host outside of normal container isolation an0613 detection of linux container escape attempts via syscalls unshare keyctl mount or process execution outside container namespaces defenders may correlate unusual system calls from containerized processes with subsequent process creation on the host or modification of host resources an0614 detection of windows container escape attempts by observing processes accessing host directories symbolic link abuse or privilege escalation attempts defenders may detect anomalous process execution with access to system level directories outside of container boundaries an0615 detection of esxi escape attempts by monitoring for anomalies in hypervisor logs such as unexpected vm operations privilege escalation events or attempts to load malicious kernel modules within the hypervisor environment references docker n d docker overview retrieved march 30
