Offensive Security Internship
il y a 2 semaines
Apple System-on-Chips (SoCs) implement multiple security mechanisms to ensure platform integrity against a broad spectrum of threats, including hardware fault attacks. These attacks are sophisticated techniques where adversaries intentionally introduce physical disturbances to disrupt normal processor operation, causing exploitable errors that can reveal sensitive data or bypass critical security mechanisms. While Apple SoCs demonstrate strong resilience against these attack vectors, our hardware security teams maintain continuous research efforts to ensure sustained protection against evolving threats. Laser Fault Injection (LFI) currently represents the most effective technique for disrupting SoC operation, but it requires expensive equipment and specialized chip preparation that are only accessible to well-equipped laboratories. Additionally, this technique cannot be effectively applied to mixed logic-memory stacking architectures where the logic (CPU) package is positioned beneath the memory package. Electromagnetic Fault Injection (EMFI) does not suffer from these limitations and is increasingly recognized as a cost-effective alternative approach. The objective of this internship is to advance the state-of-the-art in EMFI attacks against advanced semiconductor technologies like those employed in Apple products. The ultimate goal is to use these research findings to further strengthen Apple's hardware security implementations and ensure the best protection against emerging fault injection techniques.
Description
This internship provides an exceptional opportunity to work with cutting-edge hardware attack methodologies against state-of-the-art semiconductor technologies. The 6-month program is scheduled to take place in Paris during 2026 and will be conducted using a specialized test chip platform where selected software and hardware countermeasures have been disabled to permit comprehensive analysis and precise characterization of attack effects. The internship program will begin with comprehensive training on existing Electromagnetic Fault Injection (EMFI) techniques, applying these methodologies against test devices with direct CPU access. The second phase will focus on advancing EMFI capabilities through systematic setup and technology optimizations, including improvements to injection probe resolution and reductions in electromagnetic pulse duration. The final phase will involve evaluating these enhanced attack methodologies on SoCs with stacked DRAM architectures to quantitatively determine how this configuration affects attack effectiveness and success rates. Throughout the internship, you will work alongside other hardware security researchers on your missions
Minimum Qualifications
- Experience in physical attacks
- Knowledge of electromagnetism fundamentals
- Knowledge and experience in analog electronic and microprocessors architecture
- Great analytical and presentation skills.
Preferred Qualifications
- Proficiency in switching power supply techniques
