Code Execution Through Email: How I Used Claude to Hack Itself

Pynt.io — Sat, 26 Jul 2025 16:27:16 +0000

You don’t always need a vulnerable app to pull off a successful exploit.
Sometimes all it takes is a well-crafted email, an LLM agent, and a few “innocent” plugins.
This is the story of how I used a Gmail message to trigger code execution through Claude Desktop, and how Claude itself (!) helped me plan the attack.

API Discovery: The Why, The How, and 4 Tips for Success

Pynt.io — Sun, 11 May 2025 08:20:05 +0000

What is API Discovery?

API discovery is a process that involves finding and understanding APIs (Application Programming Interfaces) that exist in a system or across multiple systems. APIs are an important building block in software applications. They define methods and data formats that a program should use to communicate with other software or with the operating system.

This is part of a series of articles about API security

Some organizations take a manual approach to API discovery, where a developer or a team of developers goes through every piece of an application’s code to identify and document the APIs. However, many are turning to automated tools that can scan and detect APIs across various systems in a faster, more efficient manner.

API Attacks: 6 Common Attacks and How to Prevent Them

Pynt.io — Sun, 11 May 2025 08:14:19 +0000

What Are API Attacks?

APIs, or Application Programming Interfaces, serve as the communication protocol between different software components. APIs have become foundational to modern software development, enabling different applications and organizations to interact and exchange data.

This is part of a series of articles about API security testing

However, this increased reliance on APIs has also opened up new avenues for cyberattacks. API attacks are a type of cyber threat where a malicious actor exploits vulnerabilities in an API to harm a system. The attacker may gain unauthorized access, manipulate data, or even compromise the underlying server. These attacks can be severe and damaging, as APIs often have access to sensitive data and critical system functions.

API Attacks are not only a threat to the system's security but also to the privacy of its users. They can lead to exposure of private data, identity theft, and even financial loss...

Shadow APIs: Understanding the Risk and 6 Ways to Reduce It

Pynt.io — Thu, 08 May 2025 06:58:07 +0000

What Is a Shadow API?

A shadow API is an application programming interface that is created or used without explicit approval from the organization’s IT or security teams. Shadow APIs can emerge from various sources, including developers experimenting with new features, legacy systems that are no longer officially supported but still in use, or services integrated outside of formal IT channels.

This is part of a series of articles about API security

Unlike official APIs, shadow APIs lack oversight and governance, making them invisible to the security measures typically applied to known and documented APIs. They operate under the radar of standard security and monitoring practices. Because these APIs were not introduced through sanctioned processes, they are excluded from inventory or documentation efforts.

As a result, shadow APIs present significant risks. They are not subjected to regular security assessments, patches, and compliance checks that would normally be part of an API’s lifecycle management in a secure software development environment.

API Security Scanning: Process, Tools, and Best Practices

Pynt.io — Thu, 08 May 2025 06:49:19 +0000

What Is API Security Scanning?

API security scanning refers to the process of identifying and mitigating vulnerabilities within application programming interfaces (APIs). By examining the structure and the data flow of APIs, this process aims to uncover security risks that could lead to unauthorized data access, data manipulation, or service disruptions.

This is part of a series of articles about API Security Testing

Scanning APIs is a critical aspect of securing web applications, which increasingly rely on APIs for their functionality. These scans can be conducted manually or automated through specialized software tools.

What Is the Origin of API Security Testing?

API security testing emerged as a response to the growing reliance on APIs in modern software architectures. As the adoption of APIs increased, they became a prime target for attackers due to the vast amounts of sensitive data and functionality they expose. Initially, security concerns around APIs were addressed within broader application security efforts. However, as APIs became integral to cloud-based applications, microservices, and mobile app development, the need for specialized security testing grew.

Historically, APIs were simple and often internal-facing, which limited their exposure to external threats. But with the rise of open APIs and the increasing interconnectedness of software systems, security testing began to focus specifically on the unique risks associated with API interactions.
