Good morning. Thomas Morgan here from the ABC's breaking news team. Today we can reveal dozens of employees from the big four banks have had their login details stolen by tailor-made malicious software. In the worst-case scenario, it has the potential to leave banks' internal systems wide open.

But first, with the Coalition's costings set to be released this morning, we can reveal how Angus Taylor intends to save $40 billion. That, and plenty more from the campaign trail leads this morning.

It's day 34 of the campaign. Expect plenty of political posturing from both sides when the Coalition unveils its budget costings later today. The ABC understands Shadow Treasurer Angus Taylor will reveal $40 billion savings to the budget bottom line in a bid to claim the mantle of better economic managers. He'll achieve that by axing a number of Jim Chalmers' "off-budget" projects. You can follow today's events as they unfold on our politics live blog . Here's what else we're tracking today: 

• Analysis by David Speers: There's a huge number of voters out there who still haven't made up their mind about who to vote for, writes the ABC's political lead. That has stirred hope in the Coalition and nervousness within Labor.
• How the Greens rebranded: The party that once seemed so dedicated to the single theme of environmentalism has quietly shifted gears. Nowhere can this be seen more clearly than in Adam Bandt , whose first speech to parliament contained no mention of the key theme he's now campaigning on — rental affordability.
• Environmental commitments: There's quite the contrast between Labor and the Coalition when it comes to nature this election, with Peter Dutton vowing to target "green tape" if elected. Both parties might not get their way though, if a hung parliament comes to pass.
• We've wrapped up the ABC Your Say project. After tens of thousands of contributions, a broad theme has emerged — you want politics to be big picture, bold, and to bring about structural change. Disappointed with the campaigns run by Labor and the Liberals, some dissatisfied voters say they're voting for neither of them for the first time.
• One apparent contributor to ABC Your Say is the NT's Administrator, Hugh Heggie. Despite holding a "non-partisan" and "publicly neutral" role as a Crown representative, a personal email address of his submitted an entry appearing to express support for Labor.

'Infostealer infections': Our national technology reporter Ange Lavoipierre can reveal this morning that cybercriminals have stolen almost 100 staff logins from our Big Four banks. Cybersecurity experts warn those leaked logins are "like the open gate", that could be used to gain access to their internal corporate networks. 

India-Pakistan: Our South Asia reporters have met the cross-border communities trapped in a spiralling crisis following last week's deadly militant attack in Kashmir. Both countries have cancelled visas and restricted border crossings, tearing apart families in the process.

Papal conclave: As senior figures gather to decide the next Pope, some of the most influential cardinals won't even be inside. Today our Europe bureau lifts the lid on the delicate balance playing out inside the Vatican for those who aspire to lead the Catholic Church.

• House prices are continuing their upward march. The latest monthly data shows home values rose in every capital city in April, with rents not far behind. Despite that, there are signs the global picture, and a federal election at home, are having an impact.
• The US economy unexpectedly shrank between January and March. Donald Trump has told Americans to "be patient", deflecting blame from his tariffs to his predecessor Joe Biden.
• King Charles has opened up about his "frightening" cancer experience. But in his most candid remarks since being diagnosed last year, he also said "that the darkest moments of illness can be illuminated by the greatest compassion". Today marks a year since he returned to work following his illness. 

— Pop star Katy Perry says she is shrugging off criticism of her 11-minute journey to space. 

She goes on to call her online detractors "unhinged and unhealed".

Finally this morning, let's swivel back to the election, and specifically those pieces of paper most people barely read as they head into their polling centre.

We've dug through the how-to-vote cards in all 150 electorates to find out who the parties want to see elected, if it's not their own candidate. It's turned up some interesting results, but of course, the only person who controls your preferences is you.

That's it for this morning. Thanks for your company. We'll be back at the same time tomorrow.

Thomas and the ABC News Digital team.

Cybercriminals have stolen and shared almost 100 staff logins for Australia's Big Four banks, putting those businesses at a higher risk of mass data theft and ransomware attacks, cyber security researchers say.
