On a related note, how safe is it to do a Google search of your password?

This is actually a really interesting idea. I'd love to know how possible it would be for someone to scrape recent google searches, somehow. I'd think it would be relatively safe, but I'm still hesitant.

How many mail clients load those by default nowadays? Gmail doesn't, Thunderbird doesn't.

Um, Gmail does: https://support.google.com/mail/answer/145919?hl=en > Gmail automatically shows you the images in your messages It does have an option to turn it off, but the default is on. They will load up the image themselves, then serve it from their domain, but, as the help information shows, that still indicates an "open", it's just that all the information on who opened the email (IP address, etc) would be wro…

I believe gmail is caching these images on their own servers.

EDIT: I get what you're saying. I guess the count would depend on how long Google caches that image- or do they load it on a per email basis?

Yep, we're on the same page. The wording they use is "In some cases, senders may be able to know whether an individual has opened a message with unique image links." but I'd expect the tracking URLs themselves to be unique (most are, they are tied to an email so they know who opened the email and who didn't) so they would most likely bypass this cache. I expect the "some cases" refers to the ones where it simply gives you a count of people who opened your email, and does it by simply having a generic tracking URL.

Nice work! At a glance, the email you sent out does look sort of spammy. If you plan on doing it again you might get better feedback by making it a bit more human - ie "I'm just a guy/gal trying to help yall out - hope you don't use this password everywhere because someone posted it to pastebin.... - have a good one!" or something like that. Out of curiosity - what did you use to scrape pastebin?

I created a Twitter bot called @dumpmon (recently suspended for no apparent reason) that scraped paste sites looking for password dumps and tweeting if one was found. You can find the code here: http://github.com/jordan-wright/dumpmon . Here are some stats if anyone is interested in what it collected over approx. 2 years: http://jordan-wright.com/blog/2015/05/26/two-years-of-at-dum...

I remember chatting with you a while back as I was also working on a pastebin scraping project. http://github.com/shayanjm/pasteye

Glad to see dumpmon is still going strong :)

Shameless self-plug - I built a "pastebin scraper as a service" platform, and released it here: https://github.com/shayanjm/pasteye

Took much inspiration from dumpmon, but distributed it so users can choose their own sensitivity settings.

Sending unsolicited automated emails, even for good, may be considered rude as well.

Really? Do people seriously have this notion? Yes, sending actual spam is rude. But an unsolicited automated email can easily be deleted, especially if it's one time. I would never associate "rude" with that, maybe "annoying" at worst.

For me:

Unsolicited automated email = Spam.

Unsolicited semi-automated (i.e. fill in the blanks) email = Spam.

Unsolicited personal email actually written by a human = OK.

Followup to unsolicited email because I didn't reply to the first one = Very rude. Instant blacklist of sender.

Is there any reliable way to do this? Most mail clients will block receipt-type stuff by default...

I believe the trick is to put a hidden, 1px image in the email. Then you can track how many times it was requested.

I'm familiar with the tracking image "trick" but I assumed most email clients wouldn't load those by default. The other comments seem to indicate I was wrong. :(

This is a cute experiment, but unfortunately the integrity of the service is is easily corrupted. The biggest problem is being prone to misinformation. There's nothing to prevent people from posting arbitrary e-mail lists to pastebin, with purported matching passwords, as an effort to provoke your service to cry wolf. A few suggestions to harden the service: - provide integrity when sending the message by including a…

It is... just not on Twitter anymore. The account was suspended about a week or two ago and I haven't heard anything back on my appeal from Twitter.

I think scarecrowbob is right, but it would be very ironic if his site's DB pass was compromised ;)

It should be back now- that took much longer than I expected.

Down again for me :( Good news is you're very popular! :D
