#Analytics #Threat_Research An analytical review of the main cybersecurity events for the week (May 09-16, 2026) 1⃣  EntryPoint Hijacking // The technique introduces a stealthy approach to code injection, as it doesn't rely on API calls that create a new thread within the process context, and it is independent of the attack chain 2⃣ RCE in VSCode Copilot Chat // A TOCTOU flaw in VSCode Copilot Chat agent 3⃣ Simple bypass of the link preview function in Outlook Junk folder 4⃣ QEMUtiny - memory corruption vulnerability in QEMU's implementation of CXL Type-3 device emulation 5⃣ NGINX CVE-2026-42945 Vulnerability // The vulnerability lives in ngx_http_rewrite_module, which is part of every standard NGINX build... 6⃣ AMD EPYC CPU OP Cache Corruption // The issue remains unfixed in AMD EPYC 7002 series processors... 7⃣ Critical vulnerability in the Linux pidfd subsystem // CVE-2026-46333 8⃣ Vulnerabilities in dnsmasq allow DNS Cache Poisoning and Root Code Execution // CVE-2026-4892, CVE-2026-2291, CVE-2026-4893, CVE-2026-4891, CVE-2026-4890, CVE-2026-5172 9⃣ π RuView - WiFi sensing platform that turns radio signals into spatial intelligence ]-> Analytical review (May 02-09, 2026)

We audited 1,620 OpenClaw skills. The ecosystem's safety scanner labels 91% of confirmed threats "benign." [full reports linked] https://oathe.ai/engineering/we-audited-1620-ai-agent-skills: 1. OpenClaw 2026.2.23 shipped security updates: HTTP headers, symlink escape rejection, XSS sanitization in image galleries, API key redaction in OTEL logs. 2. A pure instruction-layer attack that overwrites your agent’s identity with an AI “girlfriend” persona — anti-transparency rules, anti-jailbreak defenses, emotional manipulation mechanics. 3. This reflects both the prevalence of credential-targeting behavior and a known tendency of the LLM grader to flag legitimate credential configuration (API key requirements, OAuth token handling) as potential harvesting. @secharvester

Google API Keys Weren't Secrets. But then Gemini Changed the Rules. https://trufflesecurity.com/blog/google-api-keys-werent-secrets-but-then-gemini-changed-the-rules: 1. Depending on the model and context window, a threat actor maxing out API calls could generate thousands of dollars in charges per day on a single victim account. 2. To understand the scale of this issue, we scanned the November 2025 Common Crawl dataset, a massive (~700 TiB) archive of publicly scraped webpages containing HTML, JavaScript, and CSS from across the internet. 3.
