PWNING THE LADYBIRD BROWSER

Ladybird browser has a bug that allows use-after-free exploitation via a constructor and a malicious handler. Attackers can manipulate the argument buffer to trigger a heap-use-after-free condition, leaking object addresses and potentially achieving code execution by overwriting return pointers. Exploiting this bug involves crafting memory structures to control the renderer and executing malicious code, which requires careful data and pointer manipulation within the browser environment.

MY SIEM-AGNOSTIC CREATIVE PROCESS TO DETECTION ENGINEERING

This post describes a process for understanding a new data source and creating detections for malicious behaviors. The first steps involve reading the documentation to understand the service and brainstorming ideas for what a malicious user might do. Then, examine the logs to determine what is considered regular or anomalous behavior, often utilizing event counts. Finally, plan out what type of detection they will write, write the detection, and then test for success, failure, and edge cases.

TAG YOUR WAY IN: NEW PRIVILEGE ESCALATION TECHNIQUE IN GCP

A new privilege escalation technique in Google Cloud Platform (GCP) exploits IAM Conditions and tagBindings to elevate access for attackers with low-risk roles. By attaching specific tags to resources, attackers can bypass restrictions and gain elevated privileges without directly modifying IAM policies. Organizations should prioritize securing tag permissions to prevent this overlooked escalation path in GCP.
