Sorry, but I can't find any "Download Sensitive File" rule: https://github.com/falcosecurity/rules/tree/main/rules

Each action must match a specific existing rule and have the same name
(I apologize because I know this convention is not documented).

So my question is: which rule is this event targeting? 🤔

[h4l0gen]

@leogr , oh i wasn't aware of this

Each action must match a specific existing rule and have the same name
(I apologize because I know this convention is not documented).

then this event doesn't belong to any specific rule. I just created it as per security concern.

@leogr i came across this rule Launch Remote file copy tools in container in https://falco.org/docs/reference/rules/default-rules/
this rule has also procedure of copying content of file. If you like i can convert this PR to Launch Remote file copy tools in container rule.
