Dutch prosecutors confirmed yesterday that Donald Trump’s Twitter account was hacked in October.
This is despite denials from both the White House and Twitter at the time that any such reports were true.
It was ruled yesterday that Victor Gevers was acting "ethically" in hacking into the US President's account and so would not face any criminal charges.
He managed to access the account by successfully guessing the password as "MAGA2020!".
Newstalk's technology correspondent said that the "ethical hack" was done to prove a point, rather than for malicious reasons like sending inflammatory tweets or messages or editing the profile.
She told The Pat Kenny Show that the incident should be a reminder for social media users to be vigilant with their own accounts, particularly passwords.
Jess said: "It's a good reminder never to have an obvious password, you're better off having something obscure that isn't one of your catchphrases.
"You should have it in different forms in terms of the capitalisation, exclamation points, different stars etc.
She added that the hack is particularly significant given that "a lot of politics is now taking place on Twitter".
"Much of what's happening in the world is now being played out on social media," she said.
"So for people to roll their eyes to the skies and say this is no big deal, it is a big deal because we know, particularly with Donald Trump, that's where a lot of politicking takes place.
"While there's no further action being taken in this particular instance, again it's a worrying reminder that people need to have an ever so slight amount of cop-on."
