𝗥𝗲𝗮𝗰𝘁𝟮𝗦𝗵𝗲𝗹𝗹 𝗗𝗮𝘆 𝟰: Over the last few days, the exploit activity around React2Shell has kept thousands of security teams working non-stop. We’re seeing mass exploitation attempts and a rapid evolution of attack techniques across the Internet. 1️⃣ WAF vendors responded quickly, but the bypasses came even faster. To their credit, nearly all major WAF vendors released initial mitigation rules within the first day of disclosure. But in the past 24 hours, we’ve seen verified bypasses of these standard rules across multiple vendors. Not because the vendors aren’t trying - but because of the inherent limitation of WAF vendors against these types of exploits. Key limitations we’re seeing in the wild: • Request size inspection caps preventing full payload evaluation • Generic patterns that fail as attackers mutate payload structure • Rules that can’t adapt to the unique behavior and context of each application WAF vendor rules are, by design, general purpose. React2Shell is not. 2️⃣ This is exactly the attack class Miggo ADR + WAF Copilot was built to defend against. Our approach is defense-in-depth by design: • WAF Copilot automatically generates application-specific rules, not generic ones • ADR’s DeepTracing sensor detects and blocks attacker behavior even when the WAF is bypassed • Combined, they cover both the “known” exploit signatures and the evasive techniques emerging now This is why runtime intelligence matters. And why generic perimeter rules aren’t enough. 3️⃣ We’ve set up https://lnkd.in/d9A5CTjP a community resource to help you keep up. Miggo’s research team is continuously generating, validating, and publishing per-vendor WAF rules using WAF Copilot. The page includes: 1. Attack Indicators to look for in your logs 2. Custom WAF Rules per vendor (more vendors being added hourly) 3. Updated analysis as new exploits emerge If your team needs help evaluating your exposure or hardening your defenses, we’re here - reach out to me or anyone on the team. #ADR #WAFcopilot #WAF #React2Shell
