A digital rights group spoke on Monday.

It said spyware from an Israeli company was used on the phone of the head of Belgrade University.

His name is Vladan Djokic.

He has been a big voice in almost two years of protests against Serbia's leader, Aleksandar Vucic.

Serbia has an important election this weekend.

People see it as a fight between the student protest movement and Vucic.

His right-wing Serbian Progressive Party has ruled for 14 years.

The Citizen Lab group studies spyware attacks.

It said it can confirm with "high confidence" that Djokic's phone was infected with NSO Group's Pegasus spyware in 2026.

It worked with the SHARE Foundation.

That is also a digital rights group in Serbia.

In September, digital rights groups said at least 14 activists and students had their phones hacked.

The phones had spyware, including Pegasus.

Another study is happening now.

It will check if the phone of associate prosecutor Rade Bajic was also hacked.

Bajic got an Apple Threat Notification on his phone in August.

He had worked on possible corruption around a building project.

The project was linked to U.S. President Donald Trump's son-in-law.

The project was later canceled.

Djokic wrote on Instagram that the hacking was a "serious attack on my privacy, security and the integrity of the post of rector."

He said it was another try to scare people.

He said it was meant to stop any critical view and public action.

Serbian authorities did not comment right away.

They have denied they were behind such attacks.

The attacks were first reported in 2024.
