You Don't Have to Outrun the (Fancy) Bear

   Two hikers are walking through the woods.  They come around a bend in the trail into a clearing where they can take a break, when suddenly a bear steps out of the woods and roars.  One hiker quickly bends down to tighten his boot laces.  The other hiker says, "what are you doing? You can't outrun a bear!".  The first hiker says, "I don't have to outrun the bear, I only have to outrun you!".

   One of the biggest changes in information security over the past two decades has been with the attackers.  Rather than the old stereotype of a hoodie-wearing loner in the basements with Mountain Dew, Twinkies and old computers, today's attacker is typically trained, smart and well-funded.  Instead of defacing websites for fun and notoriety, attacks today are a business.

   It's a simple risk/reward equation.  There is a cost to any attack.  Email-based attacks are very inexpensive to launch.  Developing sophisticated malware is expensive.  And the more expensive an attack is pull off, the higher the potential gains need to be to make a profit.

   Information security is very complex.  It's as much an art as it is a science.  There are basic things that everyone should do, like patching systems and using strong, long passwords.  And then there are complex solutions to complex problems that need to be artfully implemented to compliment the way people do their work.

   There are so many high profile breaches in the news.  Some of these are the result of highly skilled and motivated attackers going after a specific target.  But many more are "crimes of opportunity".

   As I see it, there are basically three kinds of online attacks:

Still Can't Live With 'Em


   It's US Cyber Security Month and, like clockwork, we have Yahoo! in the news again telling us that the worst case from the past just keeps getting worster (I can make up words, can't I??? :-).  They are now counting their breached accounts at over 3 billion!  How many people are there in the world these days?...  Last year at this time, they announced the breach of 500 million Yahoo! account passwords and other info (while announced in 2016, the breach actually took place in 2014, and is not the same as the password breach they had in 2012! - yes, I know... it's hard to keep up!).  In honor of both Cyber Security Month and Yahoo!, I'm re-running a post I wrote in... wait for it... 2012!  Not only is everything I wrote in that post 100% relevant today, but I even commented on that 2012 Yahoo! breach.  The more things change, the more they stay the same.  Happy Cyber Security Month!


   They're dead.  They're here to stay.

   They're safe.  They're breached.

   They're encrypted.  They're visible.

   They're complex.  They're too simple.

   Once again, the topic we love to hate... Passwords!  And, you know what else???  It's also that greatest of holiday celebrations... US Cyber Security Month!

   Passwords are a mess!  A "good" password has these features:
  • hard to create
  • hard to remember
  • hard to enter
  • probably has to be changed as soon as you memorize it
  • plus other inconsistent, random rules depending upon the site

   Perfect!

Equi-Fail!

   Or maybe we should say Equi-Fiasco!

   By now you've certainly heard about the Equifax breach including leaked social security numbers and other personal information on over 143 million people.  And there's plenty more info to come with this one as the facts continue to get uncovered.

   I certainly don't mean to be jumping on the bandwagon here.  There has already been so much coverage of this breach, but it is a big deal.  And, while I've seen a number of articles on what to do now, I haven't seen any that really cover everything you must do to protect yourself.

   Let's do that now!

   The bottom line is this... it's 2017... no one can or will protect your personal information.  You must take appropriate steps to protect yourself.  And here they are... in no particular order... the top-10 things you should do to protect your personal and financial information:

World Password Day and Teen Power

   Thurs May 4, 2017 is World Password Day!  I know that's coming up fast, but don't worry, you still

have time to plan your celebration.  No, that's not the day when you share your password with the world.  Nor is it about changing your bank password from 123456 to 1234567.

   I've written about this in the past.  World Password Day is a day to learn and it's yet another opportunity to take a look at what is protecting your personal information, your financial information, your medical information as well as your internet presence and reputation.  Most passwords provide a thin veil of protection

   On World Password Day, we should at the 4 main problems we can very easily fix:
  1. People choose weak or easily guessable passwords - the simple fix is to choose better passwords!  As I've said many times in the past, when it comes to passwords, size matters!  Make 'em long.  But even if you choose a good password...
  2. Passwords get reused among sites - this is a major problem because the attackers will try stolen passwords at other sites.  And it works.  So choose a unique password for every site on which you have an account.  But...
  3. We can't remember all our passwords - so, as we've discussed in the past, use a password vault.  The vault is a program that will help you choose great passwords, recall those passwords and protect them.  But sometimes that's not enough because...
  4. Even well-chosen passwords can be guessed or hacked - so for extra protection use two-factor authentication (also called multi-factor authentication).  Typically this means using an app on your smartphone as part of the login process.  That means, to break into your account, an attacker would need both your (long, strong) password AND your smartphone.  That's hard for the attacker to do.  And using multi-factor is easy!    Setting up 2-factor authentication is easier than ever before and is in use on many mainstream sites including Google, Facebook and Twitter.  Here's some info on sites offering 2-factor authentication.

   The WPD website has some high level guidance on each of these as well as those great Betty White videos!

   And if those all aren't enough reasons to move to 2-factor authentication, now... that pinnacle of journalism... Teen Vogue, has put out a really good article on the subject!  You can read it here.

   In addition to really good coverage of 2-factor methods and websites, the article also goes into more advanced topics like the use of a physical fob called a Yubikey.

   What is really significant is that this article is directed at a population who both grew up with technology and is used to sharing everything. The key message is that there are good reasons for protecting your information and reputation, even if you don't yet have financial assets or a job.

   So, are you ready to take the World Password Day challenge?  Start slowly.  Get a password vault and start with your most important sites: banks, insurance, investment and social media.  Change the passwords to unique long strong ones.

YAPF (Yet Another Password Fail)

   It's another week and password problems are in the news again!

   In the July 10, 2012 edition of this blog I wrote about the 2012 LinkedIn password breach.  A month earlier, LinkedIn confirmed that a Russian attacker exploited a website vulnerability and downloaded 6.5 million encrypted passwords.  You can read my old post to see why that's a problem.

   Well, some gifts just keep on giving!  Now, nearly 4 years later, a newly posted password dump from this same breach was advertised for sale on a dark web site.  Except that information on over 167 million accounts were for sale!  Of those, over 117 million had both the email and password.  Slightly different math!!!

   So why is this a problem?  Actually it's an old problem and a new problem.  Here are the key issues:
  • Poor password choices - once again, this latest set of stolen passwords shows weak passwords - the top five found passwords were: 123456 (used on over 1 million accounts!), linkedin, password, 123456789 and 12345678
  • Password reuse - since people have accounts on so many sites that need passwords, they tend to reuse them.  The one million people who used 123456 as their LinkedIn password likely reuse that on other sites.
  • Back to Work - are some of these same poor password choices being made on work systems?  Or are some work passwords being used on sites like LinkedIn and potentially included in this breach?

How To Vault (part 1)

   I was recently asked to provide more information on vaults.  I think this is a memorable one :-).


  Well, to be more precise, the question was about password vaults...
you've talked about password vaults and it seems like something should do, but I'm not sure how to start and it still seems a bit scary.
   That is a great question.  We've talked about passwords and password vaults a number of times in the past including here, here and here.

   But why do we even need something like a password vault.  There are a few reasons, and they have to do with the problems passwords pose:

It Wasn't Englebart's Fault! (part 2)

   When we have a post with a "part 1", it probably means we should have a "part 2".  Sometimes other things get in the way!

   A few posts ago we had part 1 of this discussion.  To briefly review, Douglas Englebart was an engineer, inventor and pioneer of the early internet.  He died in 2013.  He was known for a number of key ideas and inventions.  In 1967, he invented a very useful computer device that is a key component in propagating malware and facilitating phishing attacks... the Mouse!

   In part 1 we discussed how malware (malicious software) like viruses get into our computer systems.  Today we'll wrap things up by looking at why it's difficult for our organizations to stop this malware (and why it's difficult to stop this at home).

   Really, the primary issue this stuff is hard to stop is because it's too easy to click on links and attachments.  As we discussed in part 1, as long as we're clicking, we'll have problems.

   But what about anti-virus software?  Anti-virus (or anti-malware or endpoint protection) software has been around for nearly 30 years.  Yet malware problems seem to be getting worse.  (I'll continue to use the term "virus" generically, but I'm really talking about any kind of malware.)
