"Microarchitectural attacks threaten the security of computer systems even in the absence of software vulnerabilities. While x86 and ARM CPUs have been extensively studied, the rising popularity of RISC-V CPUs demands a thorough examination of their microarchitectural attack surface. With the standardization of the RISC-V instruction set architecture and the announcement of support for the architecture by major processor vendors, RISC-V CPUs are on the verge of becoming ubiquitous. In this talk, we will show a systematic investigation of the microarchitectural attack surface on the first commercially-available 64-bit hardware RISC-V CPUs..." https://lnkd.in/escXsGKE

#SupplyChainSecurity issues in #firmware are a growing concern, and the impact on #CriticalInfrastructure is alarming. I recently analyzed the UP Xtreme i14 board from AAEON, a common player in advanced industrial and embedded computing platforms. Using our risk.binarly.io platform, I scanned a firmware update for the board released just two months ago (https://lnkd.in/gbkQuQ88). The results? Multiple known vulnerabilities were detected, highlighting a familiar trend of inadequate product security practices among device manufacturers in this space. Unfortunately, this is just scratching the surface of a much larger, escalating problem. #SecureByDesign #ICSsecurity #OTsecurity

🚨 GhostWrite is the latest vulnerability affecting T-Head’s XuanTie C910 and C920 CPUs, exposing devices to severe security risks. This hardware flaw allows attackers to bypass isolation, granting them unrestricted access to device memory and peripheral controls. Even basic protections like Docker or sandboxing aren't enough to stop this deterministic attack, which executes in microseconds. Disabling the CPU’s vector extension mitigates the risk but slashes performance by 50%. This presents a critical trade-off between security and functionality. #CyberSecurity #Vulnerability #RISC_V #HardwareSecurity #GhostWrite #Finstein
