6FIEND: I'm not sure the "leaving the front door to your house open" analogies are entirely correct to use in this case.
Labour *PUBLISHED* this information in clear text on the public internet. There was no circumventing of any security. No backdoors access. Credit Card and private membership data should never have been stored on an Internet Webserver in the first place. Let alone in an unencrypted and unsecured form.
The correct analogy is that you took all of your valuable possessions and carried them all out to the street and left them lying beside the kerb. Nobody has to even enter your property to look through or take your stuff. (At least they didn't advertise the fact that they were having the equivalent of an un-manned garage sale ;-)
It is morally wrong to trawl through such material? Probably. Is it fair game to lambast someone for being so irresponsible with data that they have a "duty of care" to protect? ABSOLUTELY.
Like the duty of care in regards to responsible disclosure, anyone who works in the IT industry knows about it??? Rather than maximum political damage right?
