Students sitting their Year 12 exams are warned not to fall for "fabricated" claims their tests are available for purchase online following a hack.
The Victorian Curriculum and Assessment Authority's website remained inactive on Thursday after a hacker gained access to the site.
In a message posted to the website on Wednesday night, the hacker claimed to have distributed exam papers to hundreds of students.
But the assessment body has warned those claims were "fabricated" and designed to take advantage of students sitting exams.
"There is no evidence at all that any VCE exams have been accessed or leaked," a VCAA spokesperson said in a statement.
"These are false claims designed for financial gain from the exploitation of anxious students."
Word of the hack broke shortly before 6pm, when an unauthorised message appeared on VCAA's corporate website.
The hacker, who goes by "DaggerElite," claimed to have obtained VCE exams via secure printing services used by the exam body.
According to screenshots shared online, the hacker thanked students for purchasing the exams and the website's "dogshit" security standards.
They also claimed to have hacked the website of a law firm, whose email they said they used to distribute the exam papers.
The message was soon taken down from the website and replaced with an alert that read the site was undergoing maintenance.
Social media forums were soon inundated with discussions about the hack, with many students quick to suggest it was likely a scam.
The website remained inactive early on Thursday afternoon, preventing students from accessing study materials stored on the site.
VCAA chief executive Andrew Smith said the authority had been working overnight and had engaged with schools to restore access to those materials.
"It's disappointing and concerning that somebody was able to get into our website," he told ABC Melbourne radio.
The matter has been referred to Victoria Police, whose Cybercrime Squad is leading investigations.
No sensitive student data is stored on the website and VCE examinations are expected to continue as normal, the assessment body said.
The hack is the latest in a string of headaches for the government-run body.
A 2024 blunder led to some exam questions being leaked in identical or similar online practice materials.
Premier Ben Carroll, then education minister, took responsibility for the mistake, admitting nearly half of that year's VCE exams were affected.
In April, the Victorian government unveiled a $222 million commitment designed to restore confidence in the state's exams.
In relation to the latest incident, he said exams would continue as normal, adding his sympathies were with students.
"I've done Year 12, it's stressful enough when you are trying to get through your AFL grand final of studies," he told reporters on Thursday.
