Ransomware encryption key generation using hardware data
A recently granted patent (Publication Number: US12008102B2) outlines a computer-implemented method for determining data sources that provide seed parameters for generating an encryption key by a ransomware algorithm. The method involves introducing the ransomware algorithm into a target computer system and monitoring application programming interface (API) calls made to the operating system to identify specific API calls for retrieving data about the hardware components of the system. This data is then used as seed parameters for the encryption key generation.
The patent further details the components that can be included in the data about the hardware components, such as reference numbers, identifiers, versions, dates, times, addresses, serial numbers, or unique information. The method also involves using a process monitor to track the operating system API calls. Additionally, the patent describes a computer system and a non-transitory computer-readable storage medium storing a computer program element that can execute the method outlined in the patent. The monitoring of API calls is emphasized to be done before the encryption key is generated, with the detection of increased storage activity signaling the commencement of the encryption key generation by the ransomware algorithm.
