NIST’s new password security rules beg a question …..

August 16, 2017

How long does it take to hack a 16-character password?

=======

Last week, NIST ((the National Institute of Standards and Technology) issued new guidelines for password security.

After a review, NIST concluded that its former rules — passwords to include upper and lower case letters, numbers, special characters — made logins more complicated but didn’t materially improve online security.

Now, NIST is recommending using long, easy-to-remember phrases instead of relatively short strings of mixed letters, numbers and characters.

The rationale: the longer the string, the harder it is to crack.

For example some researchers concluded that it would only take 3 days to crack a password like “Tr0ub4dor&3” —  but over  550 years to crack the password “CorrectHorseBatteryStaple”

Oh really?

The story reminded me of a prior HomaFiles post that reported on a hacking test.

Hackers were given 1 hour to crack more than 16,000 cryptographically hashed passwords.

Her are the (frightening) results …

BleachBit: Hillary’s gift to criminals …

How many times have you seen clips of the police confiscating a suspect’s computer for forensic analysis?

Pretty common on Forensic FIles, CSI and the 11 o’clock news, right?

And, the punch line is always the same …

The perps try to delete files & browsing histories, but unknowingly leave behind evidence.

Oops.

Well, thanks to Team Hillary, FBI documents and a shout-out by Congressman Trey Gowdy, criminals now have no excuse for not covering their tracks.

Gotcha: How long does it take to hack a 16-character password?

First, how many of us have a 16-character password?

If the over-under is 1, I’m betting the under.

Still, let’s pretend that that your passwords are 16-characters long – a mix of capital and lower case letters, numbers and special characters.

Here’s how long it takes to crack it …

How long does it take to hack a 16-character password?

You gotta start scratching your head a bit when the Dept. of Defense gets its Twitter account hacked and issues an internal directive to change social networking passwords.

Not obvious to me why the DOD even has a Twitter account, and laughably frightening that they didn’t already have a policy for frequent password changes.

The fiasco reminded me of a competition to see how long it would take uber-hackers to crack 15,000 15-character passwords

Online: Covering your online tracks …

December 20, 2012

It’s no secret that there are no secrets on the internet.

Google an item and related ads start appearing on seemingly all websites you visit.

Post something on Facebook, and suddenly ads become a lot more personal.

Pick up the phone during election season and the caller mysteriously knows your’ political hot buttons.

As we posted before, if you think that you’re being followed around on the net … you’re right.

So how do you avoid having your browsing linked to your real identity online?
