The function is in a Module called Check-HaveIBeenPwndStatus & the current function is called Check-HaveIBeenPwndStatus with only the 1 parameter –Account in which you pass your email account across
So you would call it via Check-HaveIBeenPwndStatus –Account ‘bar@foobar.com’ and you’ll either get back 1 of 2 messages – A warning if it is found like the below
WARNING: We have your account foo@bar.com marked as having been pwnd on the following sites 000webhost Adobe Black Hat World Flashback Gawker MPGH Stratfor – Please Check and change your passwords across other sites as soon as you can!
Or you’ll get back the following (obviously with your account details)
Although bar@foobar.com has not been found in this database of PwndSites we advise that you change passwords regularly for any other accounts that may be linked to bar@foobar.com for your own protection
Hopefully adding in this function into a profile script that will run once a month (or week or even daily if you need it) will save you some possible headaches in future.
