Phoenix-Rowhammer-Attack-CVE-2025-6202

تتناول هذه المقالة التهديدات الأمنية التشفيرية النظامية التي يشكلها هجوم Phoenix Rowhammer CVE-2025-6202، والذي يمكنه استخراج المفاتيح الخاصة من ذاكرة DDR5 عبر التلاعب بالبتات على مستوى العتاد. في السنوات الأخيرة، أدى التطور الديناميكي لتقنيات العملات المشفرة إلى زيادة اعتماد أنظمة الأصول الرقمية...

DDRop: Active Memory Interposer Attacks on Confidential VMs by Dropping DDR5 Writes

Trusted Execution Environments TEEs are increasingly deployed in the cloud to protect sensitive workloads through hardware-enforced isolation, remote attestation, and transparent memory encryption. However, to meet memory performance and size demands, modern TEEs omit cryptographic freshness...

New DDRop Attack Breaks Intel TDX and AMD SEV-SNP Confidential Computing

Researchers have disclosed a new hardware attack, called DDRop , that breaks the memory protection in Intel and AMD confidential computing by silently dropping writes to a server's memory, so the processor keeps reading old encrypted data as if it were current. The attack requires an attacker who...
