Hacker Who Feigned Russian Hacktivist Persona Faces Up to a Decade in Prison

A California man whose theft of a terabyte of company data from Disney led the media and entertainment conglomerate to eschew Slack pleaded guilty in Los Angeles federal court to two felony charges.

Santa Clarita resident Ryan Mitchell Kramer, 25, acknowledged gaining access to a Disney employee’s computer and threatening him with publishing stolen data under the guise of a fake Russian hacktivist group called “NullBulge.”
Talks between Kramer and the Disney employee collapsed after the employee stopped responding, leading Kramer on July 12, 2024 to post 1.1 terabytes of data taken from Disney Slack channels, as well as the employee’s bank, medical and personal information. The Wall Street Journal first reported the breach, finding the leaked cache included revenue figures for Disney products as Disney+ and ESPN+ and apparent cloud infrastructure login credentials. The company in an August 2024 regulatory filing admitted the hack occurred but said it did not have a material impact on its operations.
Kramer gained access to the Disney employee’s computer by posting software online onto platforms including GitHub that purported to make artificial intelligence-generated art. SentinelLabs in July 2024 found Nullbulge – who in fact was Kramer – seeding online platforms including Hugging Face and Reddit as well as GitHub with back doored software. Kramer exfiltrated data onto a Discord channel, the cybersecurity company found.
Kramer’s plea agreement shows that Kramer used access to the employee’s laptop to access Disney Slack channels.
“We are pleased that this individual has been charged and has agreed to plead guilty to federal charges. We remain committed to working closely with law enforcement, as we did in this case, to ensure that cybercriminals are brought to justice,” a Disney spokesperson said in a statement distributed to press.
Kramer faces a maximum sentence of 10 years imprisonment plus three years of supervised released and a fine of $500,000 or more. He pleaded guilty to one count of accessing a computer and obtaining information and one count of threatening to damage a protected computer.
The incident appears to have soured the Disney company on Slack, with the Wall Street Journal reporting last September that the company began a transition to “streamlined enterprise-wide collaboration tools,” as an internal memo described it.
