Spectre rears its ugly head again as researchers show some RISC-V chips are susceptible
Researchers have demonstrated that RISC-V processors are vulnerable to Spectre attacks, revealing that the microarchitectural threat persists across different CPU instruction set architectures. The finding underscores that speculative execution vulnerabilities continue to pose security challenges nearly a decade after Spectre was first disclosed, suggesting that architectural defenses remain incomplete across diverse processor designs.

Encrypted Prompts Bypass AI Safety Guardrails in Grok and Gemini
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.
