Former Australian Prime Minister Tony Abbott had his phone number and passport details obtained by a hacker after posting a picture of his boarding pass on Instagram.
Hacker Alex Hope said he uncovered Abbott's details from his Qantas boarding pass in just 45 minutes.
He then spent months attempting to contact Abbott to alert him of the security breach.
Qantas said it had now updated its cybersecurity protocols.
Abbott posted an image of a boarding pass for his flight from Sydney to Tokyo on 21 March on his Instagram account, thanking the crew.
Hope said he received a message from a friend daring him to hack the former prime minister as they had recently been discussing the dangers of posting your boarding pass online.
The hacker explained in a blog post that he was able to find Abbott's information because his booking reference was printed on the boarding pass.
