Some observations on this file:

0. This is a file of SHA1 hashes of short strings (i.e. passwords).

1. There are 3,521,180 hashes that begin with 00000. I believe that these represent hashes that the hackers have already broken and they have marked them with 00000 to indicate that fact.

Evidence for this is that the SHA1 hash of 'password' does not appear in the list, but the same hash with the first five characters set to 0 is.

  5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 is not present
  000001e4c9b93f3f0682250b6cf8331b7ee68fd8 is present

Same story for 'secret':

  e5e9fa1ba31ecd1ae84f75caaa474f3a663f05f4 is not present
  00000a1ba31ecd1ae84f75caaa474f3a663f05f4 is present

And for 'linkedin':

  7728240c80b6bfd450849405e8500d6d207783b6 is not present
  0000040c80b6bfd450849405e8500d6d207783b6 is present

2. There are 2,936,840 hashes that do not start with 00000 that can be attacked with JtR.

3. The implication of #1 is that if checking for your password and you have a simple password then you need to check for the truncated hash.

4. This may well actually be from LinkedIn. Using the partial hashes (above) I find the hashes for passwords linkedin, LinkedIn, L1nked1n, l1nked1n, L1nk3d1n, l1nk3d1n, linkedinsecret, linkedinpassword, ...

5. The file does not contain duplicates. LinkedIn claims a user base of 161m. This file contains 6.4m unique password hashes. That's 25 users per hash. Given the large amount of password reuse and poor password choices it is not improbable that this is the complete password file. Evidence against that thesis is that password of one person that I've asked is not in the list.

Again and again, people who use Airbnb to 'hack' the rental market get little sympathy from me when the chickens come to roost. If your landlord was interested in running a tenement home/boarding house/hotel, they wouldn't sign you into a year-long lease. Also, and I know this has been hashed out before on these comment threads but he's grossing $30k a year on the back of his landlord. The landlord has every right to be upset and take action.

The author of the post seems shocked that he's in violation of anything. Perhaps he'd like to share excerpts of his lease before he feigns such shock.

Come on, the guy lives alone in a 3+ bedroom apartment in Brooklyn. We all know he signed that lease specifically to run a pseudo-hotel business under the guise of an Airbnb profile. He whines that he can't afford to live in the New York rental market without roommates; so get roommates or move somewhere cheaper.

BTW, the author is a professional writer who (gasp!) has a brand new startup to plug.

edit: It sounds like this guy has a sincere love for the experiences and newfound social life he's found when acting as an ambassador for his city. His heart is in the right place. He would make a great Couchsurfing host and probably make even greater, long-lasting relationships.

Now there's a great idea! Provide your password to some random site purporting to check if your password's been compromised.

My favorite Ray Bradbury memory is the time he came to my school to talk about his books and ended up yelling at my English teach for trying to find hidden meaning that wasn't there just for the sake of busywork. RIP Mr. Bradbury.
