I am working on firmware update file prod-build-Isat2-V02.00.03-DFU.fp2
.
I extracted it and I've got some bin files. I analyzed these binary files with binwalk:
binwalk -E RDA-533.bin
The entropy of these bin files didn't give any information and when I opened these files with IDA, it didn't give subblocks and functions. It seems these files are compressed or encrypted. How can I analyze these bin files as efficiently as possible?
