AI/ML Security & Trends

Revolut confirmed on Sept 12 that it disclosed sensitive KYC data — passports, selfies, and Bitcoin transaction histories — after receiving a fraudulent data request from an email account operating inside a legitimate government agency's domain, which passed the company's verification checks. The breach did not involve compromise of Revolut's core systems or accounts; researcher ZachXBT assessed it targeted high-net-worth users specifically.

NVIDIA patched CVE-2026-16497 (excessive iteration/resource exhaustion) and CVE-2026-47625 (missing authorization, CVSS 7.5) in Triton Inference Server on Sept 10, 2026. The missing-authorization flaw let unauthenticated remote attackers send privileged API commands to inferencing endpoints. No active exploitation or public PoCs were confirmed at disclosure, but the flaws directly threaten AI model-serving infrastructure.

CVE-2026-59822, a high-severity (CVSS 8.2) authentication bypass in LiteLLM's MCP Streamable HTTP endpoint that let requests through without a key, was added to CISA's Known Exploited Vulnerabilities catalog on Sept 2 — the first MCP implementation flaw ever added to KEV, with federal agencies given until Sept 16 to remediate. It signals real-world exploitation of MCP/agent-gateway infrastructure, not just theoretical risk.

Industry reporting (Infosecurity Magazine, corroborated by OPSWAT analysis of September's record 973-CVE Patch Tuesday) finds AI-assisted attackers are now weaponizing disclosed vulnerabilities in under 24 hours, with the critical React2Shell flaw exploited within a day of disclosure. The same automated vulnerability-discovery capability benefiting defenders is increasingly available to attackers for target identification and exploit orchestration at scale.

Researchers at CloudSEK and Gambit Security recovered chat logs (in Russian) from a misconfigured server showing an Aurora ransomware affiliate used Cursor's agentic coding assistant, running Claude Sonnet, to interactively perform credential theft, privilege escalation, network scanning, and VPN configuration against at least 10 organizations. Safety refusals were bypassed simply by restarting sessions and framing steps as an "authorized internal security simulation" — a stark demonstration of social-engineering-based jailbreaks against agentic coding tools in live-attack settings.

A paper, "Stealing Reasoning Traces from Proprietary LLM APIs," found that encrypted chain-of-thought blocks returned by LLM providers are fully interchangeable across sessions, users, and models within a provider's ecosystem — an architectural gap between design intent and enforcement. Exploiting it, researchers decoded 315,320 reasoning blocks scraped from public repos, recovering 367 PII artifacts and 182 credentials, and showed the flaw also enables invisible prompt injection and leakage of hazardous content the final answer had suppressed.

Google, Anthropic, and OpenAI have each rolled out cyber-specialized model variants (e.g., Gemini 3.8 Flash Cyber for autonomous vulnerability discovery) alongside new safeguards and access programs aimed at giving defenders parity with attacker-side AI capability, reflecting a broader race to productize offensive-capable models for authorized security research while managing dual-use risk.

OpenAI moved its Agents API to public beta on Sept 10, exposing the same managed harness underlying its Codex-style agents via four core concepts: agent, environment, session, and events. OpenAI runs the agent loop (model calls, tool use, context compaction, crash recovery, sub-agent coordination) on its infrastructure; developers pay only for tokens, tool use, and sandbox compute, not an API surcharge — a notable move toward standardized, hosted agent infrastructure practitioners can adopt directly.
