How an Emerging Industrial Protocol Family Could Put OT at Risk
New research shows how attacks against some unprotected TSN protocols could allow attackers to disrupt or manipulate physical processes
A denial-of-service vulnerability in Siemens Desigo DXR and PXC Controllers allows attackers to send malformed BACnet packets that stop affected devices from responding, requiring a device reset or reboot to restore functionality. Multiple versions across the DXR2, PXC3, PXC4, PXC5, and PXC7 product lines are affected, with CVSS score 4.3 (Medium severity). Siemens has released patched versions and recommends immediate updates, along with implementing network segmentation and access controls for these critical infrastructure control devices.

Ukrainian hacktivists exploiting the bugs, but TrueConf's reach stretches well beyond home turf
Microsoft has confirmed a maximum severity remote-code execution vulnerability in Entra ID that is being actively exploited in the wild. The company states the flaw has been fully mitigated and requires no further action from customers.
Researchers have identified a new attack technique called Cryptographic Context Injection that encrypts malicious instructions to evade safety guardrails in AI models including Grok and Gemini. The method works by concealing harmful prompts until they are decrypted within a trusted execution environment, effectively bypassing existing content filtering mechanisms. This vulnerability highlights a novel attack vector against popular large language models that defenders should monitor.
