Detection Guidance

Detection of this vulnerability involves checking if the Zephyr Project Manager Plugin version is 3.3.201 or earlier, as these versions are affected.

However, specific detection commands are not provided. Patchstack suggests that plugin-based malware scanners may be unreliable and recommends professional incident response services if compromise is suspected. [1]
