How to Use a Password Manager

A strong password looks like this:

That’s difficult to brute force, and a dictionary attack won’t work on it… but how do you remember this?

You don’t – your password manager does.

Here, I made a fake one to show you, this is inside my manager.

How it works:

1 – make 1 master password, like 25 characters long, write it down on paper, and ideally, memorize it
2 – use that master password to log into the manager. That’s it, no more remembering from here on
3 – use the password generator to create a unique password for each site you log into

Add login information, notes, click okay to save.

Each time you log into a site, you’ll go to your manager, copy the password, back to your browser, paste, done.

4 – routinely backup the database, and store it on 2 USB keys in 2 locations (why? Here.)

Which manager program to use?

Here’s a shopping list:

– 256 encryption minimum, AES-256 (Advanced Encryption Standard)
– ideally the backup file is encrypted
– has the ability to exclude certain characters when generating passwords
– can sync between devices
– be wary of plugins that are independent of any software
simple is best! It’s like a car – the more features it has, the more there is to break

Possible Programs:

– KeePassX – open source

– 1Password – (a Canadian company!)

– Password Safe – open source

Important: this is not an endorsement any of these programs, do your homework

Auto Security 40 Years Ago

If I was blogging about auto security back then, here’s what I’d be saying.

– when parking, turn off the ignition and take the key with you

– when returning to your parked car, make sure both your licence plate and VIN number plate aren’t missing

– remember to add a gas line shut-off lock

– they had car alarms back then

Why an 8-Character Password is Not Enough

Take a common password8 characters in length, composed of 1 word, 1 numbers and 1 punctuation mark:

The Attack

Using a script (a program that automatically executes tasks instead of a human), the script starts to guess all possible 8-character password combinations. This will take about 3 days.

This is a brute force attack – very little elegance, just plain old grinding it out.

The More Sophisticated Attack

Using a dictionary attack, again the attacker runs a script, but this time instead of random guessing, dictionaries of words are tried first, specifically, the most common password words are tried.

See yours in here?

The Defence

Choose 3 obscure words, string them into a sentence separated by punctuation and numbers.

Never Call when This Happens

Kind’ve clever eh: a real-sounding URL, “Support for Apple”, and a toll-free number, how nice for someone else to foot the bill.

The Attack

Pop-up window appears > you call the number > whomever answers is skilled with words > you’re tricked (social engineered) into doing something stupid, like providing a password or downloading a malicious file.

The Defence

Never call. This will never happen.

Defeat New Car Tech by Using a Wire & Wedge

I was locked out of my car at the airport a few weeks ago, and had to call for help.

A gentleman showed up with these primitive tools, and as I watched I realized how ironic that all the electronic this and automatic that can be defeated using a wire and rubber wedge.

How it works:

1 – jam the wedge between the door’s window jam and frame, creating a gap
2 – slide the wire through the gap
3 – use the J-hook on the end of the wire to unlock the door

Sorry for the grainy photos, it was like:

Guy – woah wait, are you filming this?
Me – no no, they’re just photos, it’s okay.
