My company own some PCs and laptops. The firmware and hardware may have been modified. It is a waste to dispose of that many PCs and laptops.
Are there any scans or anything I could do to determine what PCs or laptops have been compromised?
If there is nothing I could do to determine that, are there parts that could be reused because they cannot be modified?
