Password Books Make Comeback as Low-Tech Security Option
In a world where digital security breaches are on the rise, a simple, low-tech solution is making a surprising comeback: password books, now available for just AU$4.90 at AusPost branches in Australia. These compact books offer a practical, old-school way to store your credentials - but do they offer a secure solution?

@nvisosecurity brings the CAV – Covert Access Vault back!
Tired of talks? Try breaking into the box.
Spoiler: it won’t be easy 😏
Real physical access fun is back!

Would you leave your ID card with a stranger?
Many companies ask visitors to do exactly that.
Jack's Rant #5 asks whether this common practice actually improves security—or creates new risks.

Public transit hubs are high-density environments for physical social engineering and threat actors.
To mitigate risk, audit your physical security vectors: use RFID-blocking gear, secure assets with mechanical locks, and keep your firmware updated. Read the full system breakdown: https://securelylife.com/fire-escape-drills-for-kids/ #TransitSecurity #InfoSec #PhysicalSecurity #PersonalSafety

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. 💾🔐

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

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

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.

Caetra new release v1.2.0; added new shield that reacts when a webcam turns it on/off.
With this shield we are trying to avoid privacy leaks from you and others, among possible security visual breaches like harvesting information about your surroundings. Do not forget to cover your webcam with a nice cat sticker :3

The suspected rail sabotage in northern Italy highlights a recurring challenge: protecting physical infrastructure during high-profile global events.
With fires, damaged signaling components, and hours-long delays reported, the incident underscores how transport systems remain exposed to disruption even without advanced technical methods.

By now uses CanaryToken and-or TelegramBot to send notifications
I have in mind some TODOs, one of them is about monitor accelerometers, if someone has accelerometers sensors on the laptop, please send DM I'm very hype to implement this feature.

An interesting read on physical car security for keyless entry and engine starts.

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.
