WiFi in Cars is Coming this Summer

I’ve written about it at work, but this was my first experience using it in real life.

For more details, read my column from February.

1 – it functions much like the Hotspot feature on a cel phone: car broadcasts WiFi > passengers connect to car > go online

Securing your car will be similar to securing your home WiFi.

2 – choose this option, WPA2
3 – don’t bother with WEP
4 – if you check this, please leave my blog

Because remember, you are legally responsible for Hotspot users.

Blog tag = WiFi Security

About the HeartBleed Vulnerability

What is it

It is not a virus, it’s a bug in OpenSSL. It is potentially the largest vulnerability in the history of the internet, affecting an estimated two-thirds of secure websites worldwide.

Heartbleed is:

The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.

As security expert Bruce Schneier says ”‘catastrophic’ is the right word. On the scale of 1 to 10, this is an 11.”

Very basically - an attacker can move in and out, stealing sensitive data and passwords, and leave zero trace.

Sites that have little lock icon in the URL bar are what’s affected, seen when using HTTPS (like email, Facebook or banking).

What to do

Everyone: change any passwords that may use OpenSSL. Mashable has a list of affected sites here.

Small Business Owners: you need to call your IT guy now. Now. If you are taking credit cards, or any sensitive or private data, you have a responsibility to protect your customers who have trusted you.

A Rant

This Shangri-lala land we’re living in will soon end, maybe with a massive, worldwide compromise, that will force us to change the way the way we conduct ourselves online.  One day, you’ll tell your grandchildren, when people’s passwords were all the same 

This Heartbleed bug is the beginning of that. Go change your passwords.

Why I Don’t Like Airport WiFi

For years from airports, I’ve tweeted as much:

During a recent trip, I had to send a file out, so was forced to connect.

This is what happened in Chicago O’Hare (ORD):

1 – Boingo is a recognized hotspot provider, okay, I’ll connect to that.

Nope, it’s not working. Oh no, this file needs to go… I have to connect to…

2_Free_ORD_Wi-fi  Based on the shady name of this network, I bet I’m about to be MITM’d

3 – Yes I was

***

The Attack

It’s called a Man-in-the-Middle (MITM) attack.

The WiFi network I connected to is likely not affiliated or provided by the airport. Instead, it’s probably an antennae poking out of someone’s backpack.

Using a clever WiFi name, the attacker poses as a legitimate network > I connect to it > now all my traffic is run through the attacker’s computer first, before going out to the internet >as it goes by, the attacker grabs passwords, reads stuff, etc.

(I’ll better explain a MITM attack in the near future)

The Defence

Don’t go online at the airport.  It’s one of the most hostile network in the world.  This environment provides nefarious characters anonymous access to sharpen their skills.

If you must go online, avoid entering passwords, accessing sensitive data, and certainly no online banking.

Okay? Okay.

NOTE – this could be because I was already connected to Google+ , then I automatically attempted to reconnect and I was associated to the captive portal yet, although I was getting a suspicious certificate error, it’s because I was being redirected to the captive portal for login first, and that new IP didn’t resolve to “plus.google.com” that is my browser saying woah. Possibly.

LinkedIn Invites are Great for Spreading Malware

Fake LinkedIn invitations are one of the most effective methods of getting a human to click a malicious link.

This type of attack, a phishing attack (or a more targeted, spear phishing attack) works because who doesn’t want to increase their LinkedIn number up to that magical 500+. Plus, LinkedIn is maybe the most reputable of all the social media networks, so that reputation is exploited.

Additionally, LinkedIn is a business-oriented social media site, therefore, most use occurs on a computer attached to a corporate network.  And that’s more valuable to a thief than a lone, personal computer.

The Attack

You receive an email, “Let’s connect!”

It looks like a real, and safe, LinkedIn invitation.

Click on “View Profile” > goes to a fake site > where a virus / malware / etc is waiting >  that’s then installed onto your computer > now the attacker has a way into your machine > and potentially the corporate network it’s attached to.

The Defence

I rely on 2 things – my gut, and LinkedIn’s security (note this method is not 100% fail-safe.)

1 – hmm, I have never heard of this human, and something about the name / company makes my gut say wait….

2 – I open a new browser, go to LinkedIn > Invitations > is the same name on my list there?

If yes: click around to verify identity, check for connections in common, and lots of Googling.

If no: delete the email

***

Don’t be shy to ask for more clarification, proof of identity, reply with “do I know you, and how?”

And always listen to your gut, the best defence against social engineering
