these are the operations, dunno if the opcodes are correctops = ["push", "eval", "assign", "append", "pop", "call_Wqfiqb", "weird_thing", "sub", "or", "push_global", "push_null", "goto", "call2", "push_empty_arr", "jne", "xor", "mod", "index", "add", "shr", "je"]key = mem[20] = (globalThis || globalThis.window).location.hostnamemem[20] = mem[99].location.hostname + FQgZw.toString(FQgZw, []) + (mem[63].now(mem[63], []) - start_time) / 8
mem[87] = []
mem[87].append(mem[20])
mem[20] = md5(null, mem[87]) (edited)
