replyTo be fair, Ghidra was released in 2019 and in general knowledge was still hard to find even back in 2010 I feel (well, compared to 2026 in the age of AI)
replyBefore that there was, and still is, IDA Pro. Works largely the same but costs a lot, on the order of $1000/seat/year. Useless for hobbyists unless pirated, but reasonable if it's your job. Probably had academic discounts.
replyAlso a few free-but-cut-down versions like 5 (which still recognizes MS-DOS executables). I'm not going to recommend downloading it from any of the locations mentioned here but it's out there: https://reverseengineering.stackexchange.com/questions/19179...
