There are DoD standards for this. Mostly for SECRET level. Containers for SECRET level material are supposed to be tamper-evident, but not extremely resistant to attack. Filing cabinets must have welded and painted joints, and good locks. It's possible to pry open a secure filing cabinet, but the damage will show. See page 5.3.1 of [1].

The U.S. Navy does authorize label-type seals but rates their security as "minimal". See page 6.3 of [2]

Defense Counterintelligence Agency has some security seal guidelines.[3] Probably outdated.

There are "tamper-evident seals with residue." If you remove them, it makes a visible mess. [4] They also have bar-coded serial numbers. A well-resourced attacker with a lot of access time and a preliminary run to get a look at the seals and have duplicates made could probably remove and replace those. If you're facing that level of threat you probably shouldn't have anything of interest in an unattended laptop.

When the Americans secretly captured and dissembled a Soviet satellite, one of the night’s many challenges was replacing a plastic seal covering some part.

  The engine had been removed, “but its mounting brackets, as well as the fuel and oxidizer tanks, were still in place,” recalled Finer. That was when they hit a problem. The only way to see inside the machinery was to remove a four-way electrical outlet, but it was encased behind a plastic seal bearing a Soviet stamp. The team needed to leave the spacecraft exactly as they found it. But if the Soviets noticed a missing seal, the game would be up. Could they make a replacement in the middle of the night?
   … “My technicians were working all that night,” Zambernardi recalled. “That night we developed 280 photographs. We also had 60 samples of valves. We had samples of the fluid, rocketry fluid, or what have you.”
   As they put the assembly back together, the CIA car returned: inside was a perfect counterfeit Soviet seal. They could now reseal the panel and conceal their theft.

What a good read!

I’d like to think that the counterfeit was the result of an early prototype of 3D printing. But in reality, it was probably the work of a mole or the office of disguise.


And now the US complains about chinese intellectual tefts. How the world turns...

> Zambernardi also controlled a team of mercenaries he called Rudos—“tough guys”—from Mexico’s corrupt and violent Federal Judicial Police. They made treasonous Americans “disappear,” according to Mexican journalist and TV personality Jaime Maussan, who interviewed Zambernardi for a 2017 book about the mission, Operación LightFire.

the extrajudicial killings of american citizens under the directions of an american institution are mentioned so casually, one is tempted to skipped them and move to the interesting part of the story.


DoE (Sandia iirc) was the premier defensive seals lab in the US but shortly after 9/11 they removed most of their open documentation from the internet.

CIA has the main seals defeat capability in USG.


If the WestWorld S3 darknet "crime app" does not already exist, it could emerge from global fusion center coopetition with organized crime, or the economics of APT actors where on-demand, competitive teams for local tampering can support multiple remote attackers.
