Cars, Security & a Peek into my Life

Had a Good Dead Drop Idea

What’s a “dead drop” – to secretly pass an item to someone, without having to meet with them directly.

How it works – I deposit the item in a pre-determined location, then in another pre-determined location, leave a signal that I have done so. Maybe this signal is a chalk mark on a wall, a pot of red flowers on my balcony, or I blog something specific.

So!

What if the dead drop was a supply closet, inside a bathroom, inside a retail space?

Both genders could enter without arising suspicion, and there cannot be cameras inside a bathroom.

Would an employee ever find a USB key in here? Nope.

Tada!

 

 

Using a Freezer Faraday Cage to Protect from Theft

New York Times journalist Nick Bilton’s Prius was almost stolen electronically three times, so he goes looking for an answer. He finds a clue from a Toronto Police warning, which leads him to a guy in Switzerland, who explains what likely happened.

The attack – boost the car’s keyless entry signal range to trick it into unlocking.

The defence – store keys in a makeshift Faraday cage (like a freezer) where signals cannot get in or out.

This was my Friday news story for the paper.

Cadillac’s CT6’s 1st-of-its-Kind Security System

Found on Cadillac’s all-new flagship luxury sedan – the CT6.

How it works:

It uses the many cameras mounted around the car’s perimeter.

When the security sensors detect either the sound of breaking glass, or the car being moved, the cameras record 360-degrees around the car, then save the footage to the car for later retrieval to a memory card.

Seems obvious how to defeat the system – the thief deletes the footage. However, GM is at the forefront of WiFi in cars, so I expect soon for the video to be uploaded to the cloud, or sent to the owner’s phone.

Why Change your Password Every 3 Months?

At work, you’re probably required to change your password every 3 months or so.

Why? To restrict access.

It’s to kick out an attacker that may already be inside your system.

That’s it; simple and logical eh.

Because remember the golden rule – it’s not IF you’re compromised, it’s WHEN (more here)

Small business owners – it’s good practice to do this at least once every 3 months, ideally more. And when you do, be mindful of this sad stat – the more often employees are required to change passwords, the higher the chance it will be both written down, and super crappy, example: Summer2014 and Winter2015

A good password looks like this:
M{c^TJ.`?W@Y?I6i1@O%yq4?o

Today is World Backup Day

Although really, everyday should be backup day. Here, I made a list:

The Minimal to Backup

– password manager file (you have one right)
– contacts
– calendar
– bookmarks

Things to remember:

– always backup twice – here

– do big backups in chunks  – here

– if you’re using the cloud, here’s what your data looks like this

– and if everything goes west, data can still be recovered from this
