Cyberattackers have breached a high-profile entertainment and media law firm, infecting the practice with ransomware and stealing files that apparently pertain to its star clients, including Lady Gaga, Madonna, Elton John, Barbara Streisand, Bruce Springsteen, Mariah Carey and Mary J. Blige.
A cyber analyst who requested anonymity provided SC Media with content posted on the Sodinokibi/REvil ransomware group’s website that claims the attackers stole 756 GB of data from the New York-based firm Grubman Shire Meiselas & Sacks.
One sample document that was posted looks to be a contract for a Madonna tour organized by events promoter and venue operator Live Nation. The contract includes one employee’s Social Security Number.
In addition to contracts, leaked data reportedly also includes nondisclosure agreements, phone numbers, email addresses and personal correspondence.
Nicki Minaj, Christina Aguilera, Cam Newton (listed on a folder as Cam New), Ella Mai, Bette Midler, Jessica Simpson, Run DMC, Idina Menzel Priyanka Chopra, Madison Beer, OutKast and Andre 3000HBO’s are among the other artists whose files also appear to haven been taken.
Typically, ransomware attackers will continue to release stolen files in piecemeal fashion until the victim pays up in order to restore their encrypted files and prevent any additional damaging leaks.
SC Media reached out to Grubman Shire Meiselas & Sacks for comment, but has so far not received a reply. However, the law firm officially confirmed the breach to the entertainment publication Variety.
