r/Safes

I know this Safe is a throwaway, but I’m trying to salvage it for a customer.
I’m wanting to avoid damaging the boltwork. I know I could pick the tubular lock, but it might be even cheaper than a standard one that might pick won’t fit in. Anyone familiar with a Dp?
Thanks

The vault two floors under the Antwerp Diamond Center was the diamond trade's gold standard, in a city that handles roughly 80 percent of the world's rough diamonds. The control stack:

• Combination lock, 100M+ possible sequences
• Separate keyed lock
• Multi-tonne steel door
• Magnetic field sensor on the door
• Seismic sensor for drilling or force
• Light detector
• Infrared heat-and-motion sensor
• Doppler radar sweeping the chamber
• Camera coverage on the approaches
• Private guard force monitoring the whole apparatus

Ten controls, each independently credible, and the industry's assessment was that the stack was effectively absolute. Dealers stored inventory there specifically because nobody believed it could be opened.

Over the weekend of 15-16 February 2003 a crew opened it without tripping anything, forced roughly 100 of about 160 safe deposit boxes, and left with north of $100 million. No weapons, no violence, no forced entry into the building. It wasn't discovered until staff came in Monday morning and found emptied boxes and missing tapes.

What each control actually fell to

The IR heat-and-motion sensor — the layer specifically designed to catch a warm body moving in a dark room — was temporarily blinded with a film of ordinary hairspray, long enough for someone to reach it and physically disable it.

The magnetic contact on the door, which should have fired the instant the door broke its field, was defeated by holding the two halves together with aluminum and tape so the field never opened.

The light detector was covered. The combination had been captured weeks earlier by a concealed camera recording the dial being turned.

The University of Washington security group made the point that lands hardest here: taken individually, the exploit against each of the ten high-tech controls looks trivial to the point of absurdity.

Why that's the interesting part rather than the funny part

The stack was never ten independent defenses. It was ten expressions of one shared assumption — that no attacker would get close enough, for long enough, to study the set.

An IR sensor is formidable if you meet it by surprise in the dark. It's a can of hairspray if you've known its make and position for two years. A magnetic contact is unbeatable if you don't know it exists and a strip of tape if you do.

The stack's real security was a sum of surprises. Remove surprise and the layers stop multiplying difficulty and start merely adding to a to-do list. Ten controls became a sequence of known problems with known answers, and the arithmetic changed from multiplicative to additive.

That's the failure mode, and it's the one the industry eventually internalised the hard way — which is why the impenetrable perimeter got abandoned in favour of assume-breach, continuous monitoring, and blast-radius limitation.

The access model

Leonardo Notarbartolo didn't break in to study the vault. He rented in it.

For roughly two and a half years he posed as a diamond merchant with an office and a safe deposit box in the building, which gave him an unremarkable reason to come and go and to descend to the vault whenever he liked. From inside, he filmed the door and its controls with a concealed camera, took notes on guard schedules and the brand names of the locks and safes, and at some point obtained building blueprints. He carried all of it back to Turin and built a complete model of the target.

He defeated the vault by being welcomed through it, repeatedly, until he understood its controls better than the firm that installed them. The taxonomy for that is a decade old now — legitimate access, long dwell, extensive reconnaissance, single objective, exfiltration in one event — but Antwerp is the physical-world version, and it predates the vocabulary by years.

The control that was actually missing

Everything in the stack was a prevention control. The vault could be opened, and there was no meaningful capability to notice that it had been.

It was opened, occupied for around two hours, comprehensively looted, and closed again — over a weekend, with nobody watching, and the only record of any of it walked out the door in a bag. Detection lag was roughly 40 hours, and detection when it came was a human noticing empty boxes.

Ten prevention controls, zero response capability, and log integrity that depended on the logs being physically present in the building the attacker was inside.

The cleanup

They engineered every step of the intrusion and none of the exit.

The evidence bag was supposed to be burned. One crew member, left alone with it, convinced himself he heard someone coming, scattered the contents across a patch of ground off the E19 and fled. The land belonged to a retiree with a documented hatred of litterers and a habit of reporting illegal dumping.

Within about 48 hours he found the pile and called the police. Recovered from it: a Diamond Center videotape, envelopes from the building, payment stubs, a business card belonging to the crew's electronics specialist, a discarded SIM card, a supermarket receipt whose timestamp let investigators pull store camera footage of one of the crew, an invoice for a low-light surveillance system naming Notarbartolo as the purchaser, and a half-eaten salami sandwich carrying his DNA.

Notarbartolo drew ten years. Others got five apiece. Several participants were never identified. Almost none of the diamonds were recovered, because loose stones are fungible, anonymous, and effectively untraceable once they re-enter the flow through Antwerp and Mumbai and Tel Aviv.

The attack was the engineered part. The cleanup was the part that generated attributable artifacts, which is more or less exactly how sophisticated intrusions get attributed now — not by failing to get in, but by reusing infrastructure, leaving metadata, or otherwise producing the digital equivalent of a sandwich with your DNA on it.

The question I'd put to this sub: the Antwerp stack failed because ten controls shared one assumption and nobody stress-tested the assumption rather than the controls. In practice, how often does a layered architecture get audited for correlated dependency — where the layers look independent on the diagram but all rest on the same premise about attacker dwell time, or the same identity provider, or the same assumption that a tenant with valid credentials isn't the threat? I've seen plenty of control-by-control audit. I've seen much less "what single assumption, if false, degrades all of these at once."

I’m looking at getting a safe for valuables and irreplaceables. My main concern is fire, not theft. Nearly all the safes I’ve seen in my initial searches have electronic locks rather than combos or other mechanisms. If there is a serious house fire, would these locks not melt or become unusable? I suppose combination locks have similar risk but it seems less so. Anyone have any guidance? Or direct experience?

It’s a Hollon RG-22E White Republic and it comes with a S&G spartan electronic lock. I believe I can have it switched for a S&G Spyproof combination lock for free, but not 100% sure.

If it is free, I think I’d like a combination lock because I feel like they’re more secure against burglary attacks. I just feel like the electronic locks are so much more vulnerable due to hacking, manipulating wires, all that stuff. (I’m no expert but hopefully you get what I’m saying).

A couple of things I’m NOT concerned about are being able to get into the safe quickly (digital), or someone looking over my shoulder (spyproof combination). I’m just looking for the most reliable security from attacks.

Thank you all for your advice. I’d love to hear about any stories, feedback, or experiences you guys might have had with the two models listed above

I want to get a safe rather than a cabinet, was wondering my house has a wood floor with a crawl space and I have a garage with 4 inch slab but the temperature fluctuates heavily and obviously don’t want condensation build up on my investment not sure what to do the best choice would be the garage but for one it’s like 200 feet away from the house not sure where to put one if I got one the one I was looking at was the browning field and stream 33 gun safe
