Background
Cisco Talos reports that this wiper overwrites file-system-related artifacts with random data produced on the fly. It enumerates the attached storage media, spawns a dedicated thread for each drive and volume across every recorded path, and overwrites those artifacts using randomly generated bytes. The wiper also pulls several NTFS file-system attributes and overwrites them too. On top of that, PathWiper wrecks files on disk by overwriting them with randomized bytes.
