Sécurité décentralisée, niveau 1970. Pour injecter un triple zéro (000) dans la matrice de ce terminal Burroughs, il faut littéralement tourner une clé physique.
C'est le protocole "Cold Storage" le plus stylé de l'histoire. Pas de hack possible sans crocheter du bronze. 💾🔐

📰 FBI Warns 'Silent Ransom Group' (Luna Moth) is Sending Operatives In-Person to Steal Data
FBI WARNING 🚨: 'Silent Ransom Group' (aka Luna Moth) is sending operatives IN-PERSON to offices, posing as IT support to steal data via USB if remote hacks fail. Law firms, healthcare & finance targeted. #SocialEngineering #PhysicalSecurity

The cameras are already on the wall.
Turn existing installs into monitored CCTV - and keep the customer relationship yours.
AI-prefiltered events, multi-operator locking, keyholders clearing their own alerts in real time.
Integrates with Immix, Sentinel, CONXTD - or run it yourself.

What's stopping you adding monitoring to your existing base?

The FBI is warning US law firms about a cybercrime group that exfiltrates data physically — in person. Not a phishing kit, not a zero-day: human presence on-site. A reminder that threat modeling stops too early when it ends at the network perimeter. #infosec #threatintel #physicalsecurity

Camera, edge, or cloud analytics - each has a different cost, latency, and accuracy profile.
Camera: lowest cost at scale, fixed at firmware.
Edge: upgrades as algorithms improve, works across 200+ camera manufacturers.
Cloud: best for verified alarms, highest cost per camera.TetherX runs all three on one platform, one timeline, one bill.
Which layer do you lean on most for multi-site deployments?

I attended the AITP Chicago Security SIG tonight at RSM and left with one clear takeaway: a $200 device called Flipper Zero can clone your building access badge and bypass the physical security your organization worked so hard to set up. FBI Chicago Intelligence Analysts and an InfraGard board member explained how these devices work and where organizations are vulnerable. The room was full of security professionals, many of whom had that familiar look, realizing a threat they thought was unlikely is actually much closer to home.
Here are a few key points from tonight:
・ You can buy Flipper Zero on Amazon, and teenagers are posting demo videos on YouTube. If your physical security plan assumes attackers need special equipment, that assumption is no longer true.
・ Most enterprise security programs barely address RF-based attacks on access control systems. We invest heavily in endpoint protection and network monitoring, but the badge reader by the server room often gets overlooked.
・ Mitigation is practical. Encrypted credentials and multi-factor physical access are real solutions. Most organizations just haven’t made them a priority because the threat seemed remote.If you’re a CISO or CIO and haven’t reviewed your physical access controls for RF-based attacks, now is a good time to add it to your to-do list.
Thank you to AITP Chicago, the FBI, InfraGard, and RSM for a great discussion.https://aitpchicago.com/event-6680905

Hardware shortages are killing deals. Quotes expire, lead times stretch, clients walk. 🔧
TetherX runs on whatever you can source - spare servers, refurb gear, even a Raspberry Pi. Quote Monday, install Friday.
Same platform. Same features. Any hardware, any camera brand, any site size.
No forklift upgrade when stock returns. Just scale.
What's the longest lead time that's cost you a job recently?

Physical Security Lapses Expose Sensitive Servers
Your cybersecurity is only as strong as the physical locks on your servers - and a recent case where a server-room lock proved laughably easy to bypass is a stark reminder of this often-overlooked vulnerability. Leaving sensitive servers exposed is like leaving a car with cash in the console unlocked - it's an open invitation…

Why a Locked Floppy Disk Could Be Safer Than a Modern Network
Photo by CCDBarcodeScanner, licensed CC BY-SA 4.0 via Wikimedia Commons.Dear Cherubs, in the 1990s, office security had the elegance of a locked drawer and the threat model of a very determined coat thief. Floppy disks were the workhorses of the era, and Britannica notes they were popular from the 1970s until the late 1990s, made of flexible plastic coated with magnetic material. Before the internet became an everyday business utility, many workplaces were still mostly offline; Pew Research found that in 1995 only 14% of U.S. adults had internet access, and 42% had never heard of it.
THE LOCKED-BOX LOGIC
If your payroll files, drafts, and backups lived on removable media, the cleanest security move was physical control. Put the disks in a cabinet, lock the cabinet, and hope nobody on the third floor had a master key and a curious streak. It was a blunt system, but it worked because access was local, slow, and obvious. If someone needed a copy, they usually had to walk over, ask, sign something, and maybe endure a suspicious look from whoever guarded the supply room.
That is the part people forget when they romanticize the old days. The security was not magical; the attack surface was just tiny. To steal the data, someone usually had to be in the building, or at least within arm’s reach of the media. Annoyingly low-tech, yes. Also annoyingly effective.
MODERN SECURITY, NEW PROBLEMS
Once files moved onto networks and cloud systems, the game changed. NIST defines intrusion detection as monitoring events in a system or network for signs of possible incidents, and says intrusion prevention systems can also try to stop them. CISA says firewalls shield computers and networks from malicious or unnecessary traffic, while NIST says cryptography is used to protect sensitive digitized information during transmission and while in storage. In other words: the modern office traded one locked box for a whole stack of digital locks, alarms, and panic buttons.
Of course, the modern setup has its own virtues. Data can be backed up automatically, shared instantly, and protected with layered controls that the floppy-disk era never needed. NIST’s storage-encryption guidance still says organizations should physically secure devices and removable media, which is a polite way of saying: the box still matters, even when the box now lives in a server rack. Security did not become less important; it became more complicated, which is basically the same thing with extra meetings.
So yes, a locked plastic box full of floppies could be safer than a badly configured internet-facing system. But that is not because the past was wiser. It is because the past had fewer doors, fewer windows, and fewer strangers trying every handle on the planet at once. Security has always been a trade-off between convenience and control; we just used to do the math with keys instead of passwords.

A little work kvetching here, but willing to be contradicted by people in the know:
It is my experience that there are only two tiers of physical access control integrators: certifiably high-security operations, and everyone else.
...and my ongoing ~2 decades worth of experience with varied providers of the latter category is that they all seem to be awful without exception.

An interesting read on physical car security for keyless entry and engine starts.
https://paigehai.github.io/blog/my-keyless-car-got-stolen-so-i-worked-out-how-they-did-it/
But I doubt that any of the current mitigation techniques will in broad practice bear any fruit because ... people love the convenience. That's why they buy that sh*t. That's why they use Gmail, etc.
And manufacturers aren't moving fast (or at all), and definitely not on vehicles already sold.
In my books, the main problem mainly originates between the ears of people/customers.
