| How Safe is Your Password? |
| This article appeared in Lifehacker.
Internet standards expert, CEO of web company iFusion Labs,
and blogger John Pozadzides knows a thing or two about
password security—and he knows exactly how he'd hack the
weak passwords you use all over the internet. | | If you invited me to try and crack your password, you know
the one that you use over and over for like every web page
you visit, how many guesses would it take before I got it?
Let's see… here is my top 10 list. I can obtain most of this
information much easier than you think, then I might just be
able to get into your e-mail, computer, or online banking.
After all, if I get into one I'll probably get into all of them.
1. Your partner, child, or pet's name, possibly followed
by a 0 or 1 (because they're always making you use a number,
aren't they?)
2. The last 4 digits of your social security number.
3. 123 or 1234 or 123456.
4. "password"
5. Your city, or college, football team name.
6. Date of birth – yours, your partner's or your child's.
7. "god"
8. "letmein"
9. "money"
10. "love"
Statistically speaking that should probably cover about 20%
of you. But don't worry. If I didn't get it yet it will
probably only take a few more minutes before I do…
Hackers, and I'm not talking about the ethical kind, have
developed a whole range of tools to get at your personal
data. And the main impediment standing between your
information remaining safe, or leaking out, is the password
you choose. (Ironically, the best protection people have is
usually the one they take least seriously.)
One of the simplest ways to gain access to your information
is through the use of a Brute Force Attack. This is
accomplished when a hacker uses a specially written piece of
software to attempt to log into a site using your
credentials. Insecure.org has a list of the Top 10 FREE
Password Crackers right here.
So, how would one use this process to actually breach your
personal security? Simple. Follow my logic:
* You probably use the same password for lots of stuff
right?
* Some sites you access such as your Bank or work VPN
probably have pretty decent security, so I'm not going to
attack them.
* However, other sites like the Hallmark e-mail greeting
cards site, an online forum you frequent, or an e-commerce
site you've shopped at might not be as well prepared. So
those are the ones I'd work on.
* So, all we have to do now is unleash Brutus, wwwhack,
or THC Hydra on their server with instructions to try say
10,000 (or 100,000 – whatever makes you happy) different
usernames and passwords as fast as possible.
* Once we've got several login+password pairings we can
then go back and test them on targeted sites.
* But wait… How do I know which bank you use and what
your login ID is for the sites you frequent? All those
cookies are simply stored, unencrypted and nicely named, in
your Web browser's cache. (Read this post to remedy that
problem.)
And how fast could this be done? Well, that depends on three
main things, the length and complexity of your password, the
speed of the hacker's computer, and the speed of the
hacker's Internet connection.
Assuming the hacker has a reasonably fast connection and PC
here is an estimate of the amount of time it would take to
generate every possible combination of passwords for a given
number of characters. After generating the list it's just a
matter of time before the computer runs through all the
possibilities – or gets shut down trying.
Pay particular attention to the difference between using
only lowercase characters and using all possible characters
(uppercase, lowercase, and special characters – like
@#$%^&*). Adding just one capital letter and one asterisk
would change the processing time for an 8 character password
from 2.4 days to 2.1 centuries.
How I’d Hack Your Weak Passwords
Remember, these are just for an average computer, and these
assume you aren't using any word in the dictionary. If
Google put their computer to work on it they'd finish about
1,000 times faster.
Now, I could go on for hours and hours more about all sorts
of ways to compromise your security and generally make your
life miserable – but 95% of those methods begin with
compromising your weak password. So, why not just protect
yourself from the start and sleep better at night?
Believe me, I understand the need to choose passwords that
are memorable. But if you're going to do that how about
using something that no one is ever going to guess AND
doesn't contain any common word or phrase in it.
Here are some password tips:
1. Randomly substitute numbers for letters that look
similar. The letter ‘o' becomes the number ‘0′, or even
better an ‘@' or ‘*'. (i.e. – m0d3ltf0rd… like modelTford)
2. Randomly throw in capital letters (i.e. – Mod3lTF0rd)
3. Think of something you were attached to when you were
younger, but DON'T CHOOSE A PERSON'S NAME! Every name plus
every word in the dictionary will fail under a simple brute
force attack.
4. Maybe a place you loved, or a specific car, an
attraction from a vacation, or a favorite restaurant?
5. You really need to have different username / password
combinations for everything. Remember, the technique is to
break into anything you access just to figure out your
standard password, then compromise everything else. This
doesn't work if you don't use the same password everywhere.
6. Since it can be difficult to remember a ton of
passwords, I recommend using Roboform for Windows users. It
will store all of your passwords in an encrypted format and
allow you to use just one master password to access all of
them. It will also automatically fill in forms on Web pages,
and you can even get versions that allow you to take your
password list with you on your PDA, phone or a USB key. If
you'd like to download it without having to navigate their
web site here is the direct download link. (Ed. note:
Lifehacker readers love the free, open-source KeePass for
this duty, while others swear by the cross-platform,
browser-based LastPass.)
7. Mac users can use 1Password. It is essentially the
same thing as Roboform, except for Mac, and they even have
an iPhone application so you can take them with you too.
8. Once you've thought of a password, try Microsoft's
password strength tester to find out how secure it is.
By request I also created a short RoboForm Demonstration
video. Hope it helps…
Another thing to keep in mind is that some of the passwords
you think matter least actually matter most. For example,
some people think that the password to their e-mail box
isn't important because "I don't get anything sensitive
there." Well, that e-mail box is probably connected to your
online banking account. If I can compromise it then I can
log into the Bank's Web site and tell it I've forgotten my
password to have it e-mailed to me. Now, what were you
saying about it not being important?
Often times people also reason that all of their passwords
and logins are stored on their computer at home, which is
safe behind a router or firewall device. Of course, they've
never bothered to change the default password on that
device, so someone could drive up and park near the house,
use a laptop to breach the wireless network and then try
passwords from this list until they gain control of your
network — after which time they will own you!
Now I realize that every day we encounter people who
over-exaggerate points in order to move us to action, but
trust me this is not one of those times. There are 50 other
ways you can be compromised and punished for using weak
passwords that I haven't even mentioned.
I also realize that most people just don't care about all
this until it's too late and they've learned a very hard
lesson. But why don't you do me, and yourself, a favor and
take a little action to strengthen your passwords and let me
know that all the time I spent on this article wasn't
completely in vain.
Please, be safe. It's a jungle out there. |

| Emails you should be careful about opening |
| I have been receiving lots of emails recently saying I
have been “tagged” or from a client inviting me to
join “my life”
Please be very careful and think before opening or
replying to these types of email. | See this article from the NY Times which explains what these emails are about (you may need to click on “skip the ad” at the top right to go straight to the article).

| April 1st - the "conficker worm" may strike |
| CBS's 60 Minutes features a story you may be interested in
watching about the menace lurking on the Internet that
could affect your PC and maybe your bank account.
A new generation of hidden computer viruses and worms are
hiding on internet websites and invading the PCs of
millions of Americans, threatening to steal financial
information or cripple computers with multitudes of spam.
Threats like the new worm known as Conficker - which
experts say will be given new instructions on April 1 -
are worrying security experts, who wage war against the
evolving viruses that are often the creation of foreign
cyber gangs. | No-one knows for sure what, if anything, Conficker will do.
It would be prudent to make sure your antivirus
has not expired and is up-to-date and you have run the
latest Windows Updates, available at
www.update.microsoft.com
I recommend these antivirus applications:
VIPRE from www.sunbeltsoftware.com and NOD32 (the
antivirus, not the security suite) from www.eset.com |

| The end of the Road for XP |
| Many of you have ordered new desktops and laptops through
me in recent times.
In which case, you will know that, in general, I recommend
getting Windows XP over Windows Vista for a variety of
reasons which have been well publicized.
|
I just heard that your last chance to order a ThinkPad Notebook or ThinkCenter Desktop from Lenovo (formerly IBM) with XP pre-installed is May 20th. After that, all systems from Lenovo can only be ordered with Vista.
An XP downgrade DVD may be available to order separately - for a price - but don’t count on it!
Dell have said that they will be selling a Vista Bonus Pack with their systems - which will come with the option to run XP or "upgrade" to Vista until 2010.
Sony plan to sell a few laptops with XP preloaded until the end of June.
Microsoft have said that XP will not be available to purchase after June 30th (except preinstalled on ultra-portable low-powered laptops that are incapable of running Vista such as the Asus Eee)
If you were thinking of buying a new system (and its not an Apple) then this your last opportunity to get XP. |
