Memory

Memory access is provided by the MemoryService class. Each debugger has its own instance, which can be used through its memory attribute.

Reading / Writing 8-bit values

Signed

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(-128, 127)
>>> dbg.memory.write_int8(address=address, value=value)
>>> print(value, dbg.memory.read_int8(address=address))

Unsigned

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(0, 255)
>>> dbg.memory.write_uint8(address=address, value=value)
>>> print(value, dbg.memory.read_uint8(address=address))

Reading / Writing 16-bit values

Signed

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(-32768, 32767)
>>> dbg.memory.write_int16(address=address, value=value)
>>> print(value, dbg.memory.read_int8(address=address))

Unsigned

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(0, 65535)
>>> dbg.memory.write_uint16(address=address, value=value)
>>> print(value, dbg.memory.read_uint8(address=address))

Reading / Writing 32-bit values

Signed

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(-2147483648, 2147483647)
>>> dbg.memory.write_int32(address=address, value=value)
>>> print(value, dbg.memory.read_int8(address=address))

Unsigned

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(0, 4294967295)
>>> dbg.memory.write_uint32(address=address, value=value)
>>> print(value, dbg.memory.read_uint8(address=address))

Reading / Writing 64-bit values

Signed

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(-9223372036854775808, 9223372036854775807)
>>> dbg.memory.write_int64(address=address, value=value)
>>> print(value, dbg.memory.read_int8(address=address))

Unsigned

>>> import random
>>> address = dbg.address.from_string('VM:0x0')
>>> value = random.randint(0, 18446744073709551615)
>>> dbg.memory.write_uint64(address=address, value=value)
>>> print(value, dbg.memory.read_uint8(address=address))
