--- ## Mass APP_KEY discovery via cookie brute-force
Because every fresh Laravel response sets at least 1 encrypted cookie (`XSRF-TOKEN` and usually `laravel_session`), **public internet scanners (Shodan, Censys, …) leak millions of ciphertexts** that can be attacked offline.
Key findings of the research published by Synacktiv (2024-2025):
* Dataset July 2024 » 580 k tokens, **3.99 % keys cracked** (≈23 k)
* Dataset May 2025 » 625 k tokens, **3.56 % keys cracked**
* >1 000 servers still vulnerable to legacy CVE-2018-15133 because tokens directly contain serialized data.
* Huge key reuse – the Top-10 APP_KEYs are hard-coded defaults shipped with commercial Laravel templates (UltimatePOS, Invoice Ninja, XPanel, …).
The private Go tool **nounours** pushes AES-CBC/GCM bruteforce throughput to ~1.5 billion tries/s, reducing full dataset cracking to <2 minutes.
