China-Linked Threat Actors Weaponize New Vulnerabilities in Under a Day

China-linked threat actors deployed the critical React2Shell exploit operationally within a day of disclosure. Analysis of first-half 2026 data shows that 88% of exploited vulnerabilities were compromised within 48 hours of public availability, demonstrating rapid attacker adoption cycles.

Why it matters: Security teams managing internet-exposed applications need expedited patching processes since adversaries now exploit most disclosed vulnerabilities within two days, and nation-state actors move even faster.
