Cloudy With a Chance of Breaches – Part 1
Cloud security mistake #1: free CDN for hackers. (More in the extended version.)
Devs love the cloud. They spin up a bucket, push code, and brag about “shipping fast.” Then an auditor shows up and discovers your S3 bucket named test-prod-final-v2 is wide open to the internet. Congrats—you just built a free CDN for hackers.
Best Practice #1: Stop Leaving Storage Buckets Public
Quick Check:
AWS (S3): look for buckets with
AllUsersorAuthenticatedUsersAzure (Blob): check containers with public access ≠
NoneGCP (GCS): buckets with IAM bindings for
allUsers
Quick Fix:
AWS: Turn on account-level S3 Block Public Access.
Azure: Disable container public access, enforce via Policy.
GCP: Enforce
storage.publicAccessPrevention=Enforced.
That’s it. Ten minutes and you’re no longer on Have I Been Pwned’s guest list.

Best Practice #2: Firewalls that love everyone (a.k.a. 0.0.0.0/0 is not your friend)
Best Practice #3: IAM gone wild (users without MFA, service accounts with god mode, old keys floating around like your AOL password)
