Alright, I'll bite. Saw this script making the rounds on a few security subreddits. The pitch is always the same: "Leverage ThreatConnect's API to pull adversary behavior data for your own analytics!" Sounds great in theory. Free intel, automation, all that.
But let's cut through the hype. Has anyone here *actually* run this in a production cloud environment and looked at the downstream cost impact? Because I've seen scripts like this before. They run on a cron job, pull massive JSON blobs every hour, store them in S3 for "historical analysis," and then process them with some serverless function that nobody sized correctly.
Before I even look at the script's efficacy, my immediate questions are:
* What's the data volume per API call? Are we paginating through thousands of IOCs per run?
* Where is it writing this data? Straight to a managed database? That's a cost center right there.
* Is it running in a container on a fixed-size EC2 instance (wasteful) or as a Lambda with uncontrolled execution time (potential for nasty surprises)?
Everyone gets excited about the "what," but in FinOps, we obsess over the "how" and "how much." This script could be a fantastic tool, or it could be a $300/month line item that nobody budgeted for because it was just a "quick Python script." I'm deeply skeptical of any tool that doesn't bake in cost controls from the first line of code.
So, if you're using this thing, speak up. I want to see real numbers. What's your AWS bill look like after a month of this running? Did you use Spot instances for the processing? Are you leveraging Savings Plans on the underlying compute? Or are you just burning credits?

You've hit on the exact operational blind spot I see constantly. Even if the data volume seems manageable at first, the real cost driver is the transformation and storage layer.
I reviewed a similar project that pulled from a different threat intel API. The team didn't consider that each 'behavior' object was nested with ten sub-fields. Their "light processing" Lambda unmarshaled the entire payload, extracted two fields, and wrote both the raw and processed JSON to DynamoDB. The read/write capacity costs were an order of magnitude higher than the Lambda execution itself.
Your question about pagination is critical. If the script doesn't implement exponential backoff on API 429s, you're not just looking at cost, but at getting your API key throttled or revoked during an actual incident when you need the data most.
