Kernel-level device drivers that carry a valid vendor signature but contain publicly documented security flaws, which attackers load deliberately because the operating system still trusts the signature.

Rolled out in endpoint security pitch decks to make "we maintain a blocklist of old driver files" sound like counterintelligence work against state actors.

• Threat Actor Glamour: Framing a published vulnerability list and a blocklist as active counterintelligence.
• Signature Theater: Leaning on the word "signed" to make the problem sound exotic, when the fix is keeping a list current.

“Our platform continuously mitigates known-vulnerable third-party signed drivers across the enterprise fleet.”

“We blocked a list of outdated driver files that attackers use to gain admin access, even though the files are properly signed.”
