At the recent DefCon conference in Las Vegas, researchers opened many of the top commercially available gun safes with simple tools like a straw or a paper clip, and in one case, just by shaking it a bit. The investigation began after the researchers, Toby Bluzmanis, Marc Tobias and Matt Fiddler, learned that certain Stack-On safes, issued to some law enforcement officials to secure their firearms at home, could be opened simply by jiggling the doorknob. They then performed tests and found that the magnetic pin that open the door when the correct combination is entered could be triggered by gently bouncing the safe.
One of the researchers had his three-year old open the safe simply by lifting it a few inches off the ground and dropping it, a technique very similar to the "smack" method that Alex Lewis showed us a few months ago on common digital safes. They also tested three different models of Stack-On PS Biometric safes that featured a combination keypad, biometric fingerprint reader and key bypass. All three can be opened easily by pushing the fingerprint reader in, and using that hole to insert a wire or paper clip to move the solenoid that opens the lock.
Meanwhile, the Stack-On PC, which apparently meets TSA airline firearms guidelines, can be opened by removing the rubber plate on top of the buttons, and inserting a small pick into the button recesses to reach the locking mechanism. Alternatively, you could also use a screwdriver to insert a metal shank into the safe to reach the reset button, which would allow you to reset the combination.
The Stack-On PDS drawer safe can be opened by tearing a small hole in the soft plastic plate on the front. From there, a wire can be used to move the solenoid. The key-based bypass lock could be hacked instead using simple paperclip methods. The Stack-On QAS has space around the safe door that can fit a flat piece of metal, or even a drinking straw, which can be used to trigger the locking mechanism.
Once again, the key bypass lock is even easier, opening by applying a little pressure with a screwdriver and turning it. It's not just Stack-On safes either though, the research team opened models by Bulldog, GunVault and Amsec with similar methods, and all of them presented the same vulnerabilities. For example, Bulldog BD could be opened with the metal shank method, or by inserting a coat hangar into the battery port, causing it to short out and open.
The Gun Vault GVS, obviously designed to hold firearms, is crackable by once again peeling off a cheap rubber cover, and pushing a wire through the exposed holes on the top.
It should be noted that almost all of these methods don't do any permanent damage to the safe, and therefore can be performed without the owner ever noticing the break-in.

Neither Dunhams or Stack On would honor their guarantee. They are swindlers just like Stack On knowingly selling less than worthless Chinese safes. I am contacting all large merchants and urging them to stop selling these defective from the factory safes. I am hoping the Government will force a total recall of these products.
That all sounds great, until you find out that you can open this safe—and pretty much every safe like it—in a matter of seconds using only a magnet. A rare earth magnetto be precise. Nowadays, most rare earth magnets are made of neodymiumbut there still may be some from the '70s kicking around which were made of a samarium-cobalt alloy.
Just be warned that neodymium magnets are extremely powerfuland can quickly wreck your electronics seriously, they'll destroy and hard drive or phone almost instantlyor even lead to bodily injury or death if you're not careful. Now, watch as Mr. Locksmith gets this thing open in no time.
How to Open a Liberty Combination Safe
All you have to do to open up the safe is take your trusty sock and magnet device, then attach it to the safe. Well, it's actually not quite that easy. Many of these inexpensive safes use a nickel solenoid to activate the locking mechanism. So, you'll need to locate the solenoid. There isn't too much surface area to these safes, and it should be on the front door, so just slide the magnet around using the sock until you're able to open the safe.
You used to have to bounce these kinds of safes around to get them open. That was simple enough, but this method is quieter and won't leave any signs of damage. Now, you might be wonder about why we need the gym sock at all.
Technically, you don't, but these magnets are very strong, and the sock makes it easier to move the magnet around and detach it when you're done. If you've ever had a small neodymium magnet on your fridge, then you know what I mean. Not only does this method make it easy to bust into a safe or a standard push button lock on a doorit also won't leave any trace of intrusion, as long as you're careful.
And speaking of careful, once again, neodymium magnets are extremely dangerous —we literally cannot stress this enough. They are very powerful, and can quickly do harm to you or others around you, so stay focused when you're using them. Well, that's all you need to go out and get cracking.On Friday, though, a hacker known as Plore presented strategies for identifying a safe custom-selected keycode and then using it to unlock the safe normally, without any damage or indication that the code has been compromised.
At Defcon, researchers regularly give talks about picking and hacking locks, and there's even a whole "lock picking village" where people can learn basic skills or share sophisticated techniques. But there are always new locks to investigate and what makes Plore's techniques interesting is what they lack: any physical or even algorithmic sabotage.
Plore used side-channel attacks to pull it off. These are ways of exploiting physical indicators from a cryptographic system to get around its protections.
These aren't the most robust locks on the market by any means, but they are known to be pretty secure. Safes with these locks are the kind of thing you might have in your house. In practice, Plore was able to defeat the security of two different safe locks made by Sargent and Greenleaf, each of which uses a six-digit code.
They are the lock manufacturer of choice on Liberty brand gun safes, among others, and safes featuring those locks are widely available at major stores," Plore told WIRED.Oracle session sql text
Plore said he didn't have time before Defcon to try his attacks on other lock brands, but he added, "I would not be particularly surprised if techniques similar to those I described would apply to other electronic safe locks, other electronic locks in general e.
For the Sargent and Greenleafa lock developed in the s and still sold today, Plore noticed that when he entered any incorrect keycode he could deduce the correct code by simply monitoring the current being consumed by the lock. And from that we learn something about the state of the lock," Plore explained. As the lock's memory checked the input against its stored number sequence, the current on the data line would fluctuate depending on whether the bits storing each number in the code were a 0 or a 1.
This essentially spelled out the correct key code until Plore had all of its digits in sequence and could just enter them to unlock the safe. Bafflingly easy. For the second demonstration, he experimented with a newer lock, the Sargent and Greenleaf Titan PivotBolt.
This model has a more secure electronics configuration so Plore couldn't simply monitor power consumption to discover the correct keycode. He was able to use another side-channel approach, though, a timing attack, to open the lock.
Plore observed that as the system checked a user code input against its stored values there was a 28 microsecond delay in current consumption rise when a digit was correct. The more correct digits, the more delayed the rise was.
This meant that Plore could efficiently figure out the safe's keycode by monitoring current over time while trying one through 10 for each digit in the keycode, starting the inputs over with more and more correct digits as he pinpointed them. Plore did have to find a way around the safe's "penalty lockout feature" that shuts everything down for 10 minutes after five incorrect input attempts, but ultimately he was able to get the whole attack down to 15 minutes, versus the 3.Liberty Safe Torture Test 🔥
They're going to use a crowbar or a hydraulic jack from your garage or if they're really fancy they'll use a torch," Plore said. We see other systems that have these sorts of lockout mechanisms. WIRED reached out to the company for comment but hadn't heard back by publication time. Even though no one would expect this type of affordable, consumer-grade lock to be totally infallible, Plore's research is important because it highlights how effective side-channel attacks can be.
They allow a bad actor to get in without leaving a trace. And this adds an extra layer of gravity, because not only do these attacks compromise the contents of the safe, they could also go undetected for long periods of time.A Liberty safe provides solid protection for your valuables.
Liberty goes to great lengths to ensure their safes are durable and reliable. Unfortunately, even the sharpest of people may forget how to open their safe when they need to get into it. It's easy to learn the how to open manual, motorized electronic, and direct drive electronic locks.
Turn the dial right, passing the second number of your combination twice and stopping on it the third time. Turn the dial left, passing the third number of your combination once and stopping on it the second time. Center the handle between the left and right stop points. Failure to do so can prevent the lock from opening. Enter the six digit combination to your lock, followed by the pound sign.
After pressing each number the lock will electronically chirp and the red LED on the keypad will momentarily light up. Listen for the sound of the lock retracting. After hearing the lock retract you have six seconds to open the door. If you don't open it within six seconds the lock will reengage and you will have to start over. When you hear the lock retract, turn the handle and open your safe.

Step 1 Make sure the arrow on the outer rim of the dial is aligned with the top of the dial. Step 2 Turn the dial left at least four times before stopping on the first number of your combination. Step 3 Turn the dial right, passing the second number of your combination twice and stopping on it the third time.
Step 4 Turn the dial left, passing the third number of your combination once and stopping on it the second time. Step 5 Turn the dial right until the dial stops, usually around 87 on the dial, and open your safe.
Step 1 Center the handle between the left and right stop points. Step 2 Enter the six digit combination to your lock, followed by the pound sign. Step 3 Listen for the sound of the lock retracting. Step 1 Center the handle between the stop points to make sure the lock will open. Step 2 Turn the keypad counterclockwise until it stops.Nice attack against electronic safes:. Plore used side-channel attacks to pull it off.
These are ways of exploiting physical indicators from a cryptographic system to get around its protections. Here, all Plore had to do was monitor power consumption in the case of one safe, and the amount of time operations took in other, and voila, he was able to figure out the keycodes for locks that are designated by independent third-party testing company Underwriter's Laboratory as Type 1 High Security.
These aren't the most robust locks on the market by any means, but they are known to be pretty secure. Safes with these locks are the kind of thing you might have in your house. Tags: hackingsafesside-channel attacks. I wonder how you can design these to prevent side channel attacks. My first thought would be salted hash, but the hash can still be recovered, and with a six digit numeric code it won't take long to brute force, especially since you would want a very long battery life for something like this which limits the use of key stretching algorithms.
I don't know a lot about electronic circuitry, but it seems to me that if you can design it to store both the hash and the one's complement of the hash, and then compare them both in parallel, then the power consumption should not vary. It sounds like these side channel attacks could be prevented by storing all six digits of the combination in an internal buffer regardless of the correctness of each digit, then running the computation to determine if the digits are correct or incorrect once the sixth digit is entered.
That way, the processing time for each digit is the same as they are entered because the digit is simply being stored regardless of correctness. If you also make sure your compare function does not have an early abort meaning you always check all six digits and 'OR' a bit indicating correctnessyou can keep the time used by the compare function identical--giving no hints as to which digit is wrong--and you minimize current variations during compare.
Looks like a major design blunder, for the lock to process the input piecemal instead of storing the input and processing it just once at the end.
Also I don't understand why the processing is done in microseconds rather than after maybe a one-second delay. You would expect from analogy of picking mechanical safe locks that these attack modes would be well understood. Any power consumption should only be for charging the batteries in the safe. Otherwise, no power draw when the combination lock is being manipulated during which time, power draw for charging is turned off.
Further, as the article points out, these locks are fitted on certain gun safes. The devious bastard in me fantasizes about flitting around the country, cracking said safes wherever found, piling lethal contents on the floor under a note: "Your safe isn't". I'm unfamiliar with the implementation of these locks. JeffP, It looks like these locks have the battery accessible when the safe is locked.
That does make sense you don't get locked out permanently if the battery runs outbut it makes it rather easy to do side-channel attacks.
I would want to have the battery on the inside of the device. Preferably it would be rechargeable, but charging it would disable the unlock feature while it is charging. SoWhatDidYouExpect came to the same conclusions about charging. It makes sense if you think about it. I have a whole bunch of electronic punch key safes that I've built computers in and I can tell you for free even the manufacture of the mechanics is fairly ropey, especially if it's main feature is an A60 fire rating.
The second hint is that UL rating like many other ratings is based on standardised tests. So in all probability "the design was to the test" But there is another issue that tends not to get talked about with electronic locks and that is "What do you do about a flat battery? Anyone who has a transistor radio or other battery powered device will know that battery life is dependent on several factors such as use and temprature. Battery failure would in a secure design be either the first or second biggest "customer service issue" along with "forgetting the combination".The dehumidifiers have thicker prongs and it catches on the contacts of the new outlet kit.
Two simple solutions usually work. Try to plug in another 3-prong plug that has thinner prongs. If it works, that usually spreads the contacts out and the dehumidifier will work.

It that doesn't work, file an angle on the tips of the dehumidifier prongs so that it creates a wedge. Plug it in and if it works problem solved. If that doesn't work, contact Liberty's customer service department at Verify that the combination dial is set at zero before attempting to turn the key. Make sure key is fully inserted before attempting to turn key. Check lock-bolt pressure.

Bolt pressure may be due to out of place interior shelves or improper personal storage i. Redial the complete combination stopping at "0" before reaching "87". Hold dial on "0" while rattling the handle left and right. Then turn the dial right until it stops at about "87". The combination number may have shifted slightly during shipping.
Try dialing 1 up or 1 down from each number in the combination. If it opens with a new number, update your combination in this book and report it to Liberty SafePress 0. Verify that the key-lock is unlocked jagged edge of key will be facing up before attempting to turn dial.
Bolt pressure may be due to out of place interior shelves or improper personal storage. Make sure the door is completely closed and the locking bolts are in the fully extended position. Normally dial tightness varies from safe to safe. Tightness of dial may increase or decrease as dial is being turned. Verify that the dial has completely stopped turning to the right on or about "87" before turning the handle. Corner protectors packaging material may cause undue pressure on the locking bolts.
To alleviate the pressure push in on the door while pulling out and turning the handle to open the safe. If the handle turns partially the bolts may be jammed or caught up. Try rotating the handle back and forth left to right until the bolts free up.
Use a cotton cloth and light oil to rub each chrome locking bolt on the open and hinge side of the door. Verify that the handle has been completely rotated in the open position before opening the door. Check the Allen set screw located on the front center of handle under sticker or side of the handle hub for tightness.
Some safes are installed with a unique handle clutch mechanism.
Improper personal storage or over tightening the door adjusting mechanism may cause the clutch to temporarily engage. Try pushing in on the door while pulling out and turning the handle. You may have to repeat this step several times until door is open. Adjust Door. Also, verify that the handle has rotated completely and that the chrome locking bolts are fully extended.Toggle navigation. Find A Dealer Go. Find A Dealer: Go. HD Quick Vault.
HD Quick Vault open. HD Quick Vault Dimensions. Great gun safe for nightstand. I keep this safe for my home defense pistol next to my bed. Keeps my kids safe And it's easy to access if needed.
Happy with product. I have a Liberty gun safe, so I decided to purchase a Liberty gun vault for my bedroom. I purchased a HD and it worked perfect from the start. My state has strict gun laws about gun storage so I stuck with Liberty. After researching for days and looking at videos of how easy kids can brake into vaults made by other companies.
I opted for this liberty vault, I found the quality of this product superior to the other brands I looked. I have an earlier version of this safe that I bought 10 years ago. As I've always gotten good service from that product, I purchased this safe to replace a biometric unit that I've owned for several years.
Getting that safe to open was an iffy proposition. I'm going back to a more basic unit that I feel I can trust in an emergency. The safe works well and I can access it very quickly. I got the bigger HD for securing my home protection.2020 09 dnkh how to save a life movie soundtrack
The only issue is I got this one because it had a shelf but because of my size hand it gets in the way. I ended up taking out the shelf. My problem now is that I want an upright for other items.
Liberty is know for their quality so, when this came on sale it was a no brainer to buy it. I already have a Liberty gun vault so this will add greatly to firearms collection. I like everything about this safe. It's quick to open and secure when closed. The only issue that I have is the removal shelf.Rtu5024 manual
It is flimsy and bows with weight. Yes I would buy it again. The HD is everything one needs in a handgun vault.Royal enfield classic 350 engine cover
Most of my handguns I keep in my large safe but this one is perfect for keeping one or two readily available yet secure.
