Create a Console Session from IAM Credentials - Hacking The Cloud How to use IAM credentials to create an AWS Console session.

Got IAM creds but tired of wrestling with CLI flags? You can spawn an AWS Console session using aws-vault. Temporary creds work directly, long-term creds need sts:GetFederationToken first. Heads up: this is noisy in CloudTrail.

GCP Cloud Workstations Privilege Escalation - Hacking The Cloud Break out of a Cloud Workstations container through an exposed Docker socket, then access project credentials from instance metadata.

ICYMI: A look at how a familiar container escape pattern shows up in GCP Cloud Workstations. We trace a path from a container to service account.

If you’re using Cloud Workstations, this is a useful model to keep in mind.

Get IAM Credentials from a Console Session - Hacking The Cloud Convert access to the AWS Console into IAM credentials.

AWS Network Firewall Egress Filtering Bypass - Hacking The Cloud Bypass AWS Network Firewall Egress Filtering using SNI spoofing and Host Header manipulation.

AWS Network Firewall checks SNI and Host headers but never verifies the actual destination IP. Attackers can bypass egress filtering by spoofing legitimate domains while routing traffic to malicious IPs.

Break LLM Workflows with Claude's Refusal Magic String - Hacking The Cloud How Anthropic's refusal test string can be abused to stop streaming responses and create sticky failures.

In case you missed it, did you know Claude models have a "magic string" to test when a model refuses to respond? If that string enters prompt context, it can be abused to break LLM workflows until context is reset.

It's the EICAR test string of the AI age. Details:
