Last week, a vulnerability in Apache Parquet’s Java library CVE-2025-30065 was published, carrying a CVSS score of 10.0. Parquet is widely used in modern data pipelines and analytics systems, including technologies like Apache Spark, Trino, Iceberg, etc. As a result, a malicious actor who is able to deliver
During the last few months, I spent a significant amount of time reviewing system modeling literature and exploring the current advancements in this area of research. Specifically, my goal was to apply advanced machine learning including deep learning techniques to efficiently represent system events in a euclidean space and detect
Writing performant, portable, and correct parallel programs in multiprocessor systems or SMP, where each processor may load and store to a single shared address space, is not trivial. Programmers must be aware of the underlying memory semantics, i.e. the system optimizations performed by the clever beast hardware or cpu.
Spring announced on October 25, 2024, CVE-2024-38821, a critical vulnerability allowing attackers to access restricted resources under certain circumstances. The vulnerability specifically impacts Spring WebFlux's static resource serving. For it to affect an application, all of the following must be true: It must be a WebFlux application. It
Last week, I saw this post (https://www.theregister.com/2024/07/12/cisa_broke_into_fed_agency/) discussing the exploitation of an unpatched Oracle vulnerability. The unnamed federal agency took over two weeks to apply the available patch 😜. When I read the post, I was like: Is RASP or
Vulnerabilities are everywhere and here to stay. Defects can exist in source code or third-party and open-source software. However, not all vulnerabilities pose the same threat, and code that is exploitable in one context may not be exploitable in another. Focusing on what matters is crucial for remediation and prioritization,
In this blog post, I will discuss how one can use eBPF for runtime application security to detect library profile deviations. More specifically we will use stack traces to observe what libraries/functions are active in the stack when a system call is issued. Stack traces are very valuable signals
In this post, we will explore why RASP, or Runtime Application Self-Protection, is not always effective in protecting your Java applications and can be bypassed. Introduction Open source security has long been problematic, yet many organizations continue to overlook its importance. Existing sandboxing solutions such as seccomp and LSMs (SELinux,
Few companies are starting to pave the way for Application and Detection Response (ADR) including Oligo Security, RevealSecurity and Miggo Security. You may find yourself quickly lost in understanding what these solutions aim to tackle. First, each of these solutions likely focuses on what they do best. For example, Oligo
