Multiple hackers claim responsibility
In late September 2023, multiple malicious actors claimed to have stolen data from Sony, with 3.14GB of data allegedly belonging to Sony posted on dark web hacking sites. Two different malicious actors claimed to have stolen data from the technology company.
One of the groups, RansomedVC, claimed to have stolen 260GB during a cyber attack against Sony. The group made attempts to sell the data for $2.5 million. The other group, MajorNelson, refuted RansomedVC’s claims and leaked a sample of the data for free.

Sony has suffered several data breaches in the past, including a major breach in 2011 that exposed the personal information of millions of users. In August 2017, a hacker group accessed Sony’s social media accounts and deleted data from Sony systems using a variant of the Shamoon virus.
In July this year, Clop ransomware group used the MOVEit vulnerability to launch large-scale attacks. Sony discovered the attack three days later and discovered unauthorized downloads. Sony later temporarily disconnected the Internet and fixed the related issues.
Impact of the breach
The breach has potentially exposed the personal information of over 6,000 people, specifically 6,791 Americans. The leaked data include names, addresses, Social Security numbers, and dates of birth.
