Execute commands by sending JSON? Learn how unsafe deserialization vulnerabilities work in Ruby projects
Can an attacker execute arbitrary commands on a remote server just by sending JSON? Yes, if the running code contains unsafe deserialization vulnerabilities. But how is that possible? In this blog post, we’ll describe how unsafe deserialization vulnerabilities work and how you can detect them in Ruby projects.

Sign-in with World ID: XSS and ATO via OIDC Form Post Response Mode
Recently, Tools for Humanity partnered with the German HackerOne Club to run a one-week virtual and in-person Hacking Meetup. In the course of the meetup, a critical vulnerability within the Sign-in with World ID implementation was found, which affected the OpenID Connect form_post Response Mode and could allow malicious actors to take over end-user accounts at third-party applications that utilize the Sign-in with World ID mechanism. The vulnerability was addressed within a few hours after triage.

AVSS Report: System Security Adversarial Capability Preliminary Evaluation of iOS, Android, and HarmonyOS - Kernel
As consumers, when faced with five different brands and models of smartphones or ten different smart cars, it’s difficult for us to determine which one can effectively prevent our privacy from being stolen or maliciously accessed, such as our location or even hearing our conversations inside the car. Even as ordinary consumers, we currently have no way of knowing. As technology professionals who have long studied in APT(Advanced Persistent Threat) attacks, we understand that these devices can ultimately be compromised in the face of advanced persistent attacks.
Private Cloud Compute: A new frontier for AI privacy in the cloud
Secure and private AI processing in the cloud poses a formidable new challenge. To support advanced features of Apple Intelligence with larger foundation models, we created Private Cloud Compute (PCC), a groundbreaking cloud intelligence system designed specifically for private AI processing. Built with custom Apple silicon and a hardened operating system, Private Cloud Compute extends the industry-leading security and privacy of Apple devices into the cloud, making sure that personal user data sent to PCC isn’t accessible to anyone other than the user — not even to Apple. We believe Private Cloud Compute is the most advanced security architecture ever deployed for cloud AI compute at scale.

No Way, PHP Strikes Again! (CVE-2024-4577)

Becoming any Android app via Zygote command injection
We have discovered a vulnerability in Android that allows an attacker with the WRITE_SECURE_SETTINGS permission, which is held by the ADB shell and certain privileged apps, to execute arbitrary code as any app on a device. By doing so, they can read and write any app’s data, make use of per-app secrets and login tokens, change most system configuration, unenroll or bypass Mobile Device Management, and more. Our exploit involves no memory corruption, meaning it works unmodified on virtually any device running Android 9 or later, and persists across reboots.
