Hackers target US firms in FastJson RCE zero-day attacks

Attackers are actively exploiting a remote code execution vulnerability in the FastJson Java library to target US firms. The flaw permits code execution without requiring user interaction or special privileges. Exploitation is occurring in the wild against live targets.

Why it matters: Organizations using FastJson in their Java applications face immediate risk of compromise; patching or disabling the library should be prioritized if you have not already assessed your exposure.
