companion allegedly hacked as reported by Everest ransomware with details: The database totals over 176 gigabytes
Petrobras more than 90 GB
Everest group has raw seismic navigation data on hand, including ship coordinates, OBN knob positions, DGPS accuracy, and quality check data for the survey lines.
They also have reports on shots and source directions, hydrophone and source depths, barb pressures, metadata on equipment and node configurations, and initial QC reports on system status and measurement accuracy.
In addition, there are processed PDF files summarizing the survey progress, preliminary QC results, and line-by-line conclusions.
Technical details are also included, like distances and directions between sources and nodes, source offsets along and across lines, as well as ship movement parameters and equipment orientation.
If this data leaks early in the project, it could do serious financial losses for the contractor, including take penalties and costs for re-shooting lines.
Moreover, competitors who let access to the data could figure out positioning accuracy, equipment setup, and ship movement patterns, allowing them to replicate or optimize similar models and reduce the companys strategic advantage.
