Sony Pictures isn’t the only entertainment giant dealing with a massive breach.

Music icon Madonna quickly released six tracks from her latest album last week after someone stole 13 prereleased recordings—reportedly the entire album—and leaked them to the Internet. The Material Girl is now keeping all of her production material off the networks, requiring her production crew to avoid wireless and deliver files by hand-carrying hard drives, according to an interview with Billboard magazine published on December 21.

“We don’t put things up on servers anymore,” she said. “Everything we work on, if we work on computers, we’re not on WiFi, we’re not on the Internet, we don’t work in a way where anybody can access the information.”

It’s uncertain when the attack happened. A single track from the album, "Rebel Heart," appeared online in November, leading the musician and her manager, Guy Oseary, to castigate the perpetrators. While the stolen music could have been leaked by an insider, the additional release of unpublished pictures of Madonna suggests that online attackers somehow gained access to her personal systems.

“I would be grateful to any @madonna fans that can assist us in finding those responsible for the leak,” Oseary tweeted on November 28. “We appreciate your help.”

The attack reflects the issues in the Sony Pictures Entertainment breach in microcosm. Sony lost control of an alleged 100 terabytes of sensitive business information—including prerelease movies, scripts, e-mail messages, and salary information—after hackers targeted the company. The attacks aimed to punish the company for the planned release of a satirical movie, The Interview, about a comic plan to assassinate North Korea’s leader, Kim Jong-un. The FBI has accused North Korea of the attack on Sony, while the company has pulled its plans to release the movie on December 25. On Friday, President Obama called the Sony Picture’s decision “a mistake.”

While Sony is struggling to secure its network, Madonna and her production crew have essentially gone dark, keeping production systems off the Internet and closely tracking all data, she told Billboard magazine.

“We have photo shoots or video shoots, and everyone has to leave their phone at the door,” she said. “I mean, unfortunately, it sucks, but that’s the way it is. That’s how leaks happen.”

For Madonna, the leak is much more personal. In addition to an alleged 13 songs, the person or people responsible for the compromise posted previously unpublished pictures. Both manager Oseary and Madonna have taken to social media to ask for help in identifying the hackers and not downloading the material online.

“I am asking my true fans and supporters who respect me as an artist and a human to not get involved with the purchasing trading or posting of unreleased images or music,” the musician posted last week to Instagram. “I hope and pray we find the source of the leaks soon. Until then i am grateful for any leads or info and even more grateful for your support and loyalty! Please let me finish my work so i can give you my very best!”
