Pirated digital copies of the blockbuster film The Odyssey are being used to hack into viewers' computers, according to new research by cybersecurity company Bitdefender.

"Internal Bitdefender insights show that users have already tried to download malicious executables disguised as the movie," the multinational cybersecurity firm said in a statement.

The Odyssey has not yet been released online, while IMAX screenings remain sold out widely for weeks ahead in many locations.

"Only days after The Odyssey became one of the biggest movie launches of the year, cybersecurity researchers have already observed fake pirated copies distributing the Lumma Stealer malware," the statement continued.

This raises significant cybersecurity concerns, as it could allow online attackers to gain access to thousands of consumers' laptops, particularly as several illegal sites present files posing as legitimate video downloads of the film.
