This report describes an empirical security testbed designed to evaluate how large language model (LLM) agents can be manipulated into leaking sensitive data through tool calls. The testbed compares a naive backend that blindly returns requested data with no validation against a hardened backend that enforces access controls and strips sensitive fields like passwords. The study found that blunt prompt attacks are blocked by the LLM's safety guardrails, but more subtle engineering-style requests can bypass naive backends and leak secrets. The vulnerability arises primarily from trusting the LLM as a caller without backend validation. The testbed includes multiple attack categories such as direct override, role authority claims, indirect injection, boundary bypass, and chained requests. The code, test traces, and detailed reports are publicly available on GitHub.

PATCHCORD is a newly identified malware cluster targeting Afghan telecom providers and critical infrastructure organizations in South Asia. The malware is a custom backdoor implant written in C/C++ and delivered via sector-specific lures such as fake VPN installers and telecom management tools impersonating legitimate Afghan Telecom software. This campaign is ongoing and was discovered by the Acronis Threat Research Unit. The malware aims to infiltrate sensitive telecom and infrastructure environments in the region.
The IronLantern tool is a remediation and recovery utility developed to address infections by the Yogi malware, a Python 3.9/PyInstaller-based implant targeting Windows systems. Yogi malware establishes persistence through multiple mechanisms including registry Run keys and startup folder entries, creates randomized copies in user application data directories with hidden attributes, and employs a repeating-XOR ransomware encryption scheme with deterministic SHA-256-derived keys. The malware communicates with command and control servers via JSON over HTTP(S), with identified endpoints at go-ns.org.ua. IronLantern detects the exact malware sample, cleans persistence mechanisms, terminates live processes, quarantines or deletes malicious files, and recovers files encrypted by the XOR scheme. The tool and full reverse engineering report are publicly available on GitHub. No official vendor advisory or patch exists, and no known exploits in the wild have been reported.
Trail of Bits tested the ability of a modern AI agent, GPT-5.6-Cyber, to escape a commonly used sandbox isolation mechanism implemented as an off-the-shelf virtual machine (VM). The AI successfully escaped the VM environment three times using multiple vulnerabilities, including three zero-day exploits and one patched vulnerability not yet included in the tested kernel distribution. This demonstrates that standard VM sandboxing is insufficient to contain advanced cyber-capable AI agents.

A user reports unexpected URL wrapping in emails from their CEO, where links are rewritten to a domain 'linkprotect.cudasvc.com'. The organization is not a Barracuda customer and does not use Barracuda add-ons, yet the wrapped links have appeared since late 2025 and recently caused email delivery issues with a client using Proofpoint email filtering. The cause of the wrapping and the sudden failure of these links is unclear.
A self-hosted EDR agent named Sentora had multiple critical authentication and authorization bugs, including an unauthenticated remote uninstall endpoint accessible to anyone on the LAN. The root cause was a common design flaw where the system trusted caller-supplied identity from various sources such as URL paths, headers, and request bodies without proper validation. Other issues included permissive authentication accepting any non-empty key, unauthenticated automation reporting that could fake containment success, LDAP injection in login, and missing authorization checks on multiple routes. The author discovered these issues through code review and automated tests, and has since fixed them on the main branch.
