Hackers leaked 190GB of sensitive Samsung data

California-based graphics processor maker Nvidia has confirmed that its networks were hacked. The company witnessed a cyber attack last week where hackers stole data from the company’s servers, including sensitive information and employee credentials. However, along with details about Nvidia, hackers have gained information about South Korean tech group Samsung.

On March 4, 2022, Lapsus$ Group allegedly leaked “a large collection of confidential data from Samsung Electronics”, as reported in a report by bleepingcomputer.com. The hacker group claims that it contains 190GB of data from Samsung which it stole while receiving 1TB of data from Nvidia’s servers. As noted in the report, the data held by Lapsus$ is detailed below.

  • Source code for each Trusted applet installed in the Samsung TrustZone environment used for sensitive operation.
  • Algorithm for all biometric unlock operations.
  • Confidential source code from Qualcomm.
  • Source code for Samsung’s Activation Server.
  • Full source code for the technology used to authorize and authenticate Samsung Accounts, including APIs and Services.

If the information given in the report is indeed correct, that is, if the hackers have this data, then it can cause great harm to Samsung.

The hacker group leaked this information via torrent and said that it will deploy more servers, which will increase the download speed. The data appears to be in three parts – 69.95GB, 30.68GB and 89.59GB. These files contain information about security/defense/knox/bootloader and other items. Apart from this, it contains the source code about the encryption of many devices.
