โ ๏ธ **Threshold**: **Medium/High**. It requires **social engineering** or user interaction. ๐ค The victim must be **tricked** into calling Help Workshop to process the malicious file.โฆ
๐ฃ **Public Exploit**: **Yes**. Exploit-DB ID **3149** is available. ๐ A C++ PoC visualization is also linked (`cnt-expl1.cpp`). ๐ Wild exploitation is possible if the exploit is distributed.
Q7How to self-check? (Features/Scanning)
