Cabinet minister Christopher Pyne has shrugged off the hacking of his Twitter account, saying it’s a good reminder to keep changing passwords.

The defence industry minister also said there were no implications for national security after the hacked account was used to “like” a gay pornography tweet.

“It’s a good reminder to us all, quite frankly. We need to keep changing our passwords and being aware of not anybody out there wishes us goodwill, unfortunately,” he told Nine Network on Friday, adding that the incident was annoying as well as embarrassing.

Labor frontbencher Anthony Albanese said there was no need for an investigation.

His Twitter account “liked” a pornographic post

“We are satisfied that this is a public Twitter account, there is no connection between the Twitter account and Christopher’s defence portfolio,” he told the network.

On Thursday morning, Mr Pyne tweeted: “I was hacked overnight!”

“Someone tried to hack my social media yesterday. Maybe they are making mischief over the plebiscite?”

He noted he was asleep at 2am when the pornographic image was “liked”.

So concerned was conservative crossbench senator Cory Bernardi that he gave notice of a motion in the Senate calling on the government to report to parliament on the issue.

“Deeply concerned about national security implications of hacking of Pyne’s social media account,” Senator Bernardi tweeted on Thursday.

“Need full investigation and report in case is foreign agent trying to influence elections.”

The post has since been removed from Mr Pyne’s “like” list on Twitter.

It is not the first time a high profile figure has fallen prey to porn-liking hackers.

Earlier this year, the Australian Border Force was asked to explain why Commissioner Roman Quaedvlieg’s Twitter account liked a pornographic tweet.

It came after United States Republican Senator Ted Cruz was also forced to explain his account “liking” a pornographic post in September.

Senator Cruz blamed the “inadvertent mistake” not on hackers but rather “a staffing issue”.
