# leakfind
|
|
|
|
```text
|
|
usage: leakfind [-h] [-p [PAGE_NAME]] [-o [MAX_OFFSET]] [-d [MAX_DEPTH]]
|
|
[-s [STEP]] [--negative_offset [NEGATIVE_OFFSET]]
|
|
[address]
|
|
|
|
```
|
|
|
|
Attempt to find a leak chain given a starting address.
|
|
|
|
Scans memory near the given address, looks for pointers, and continues that process to attempt to find leaks.
|
|
### Positional arguments
|
|
|
|
|Positional Argument|Help|
|
|
| :--- | :--- |
|
|
|address|Starting address to find a leak chain from (default: $sp)|
|
|
|
|
### Optional arguments
|
|
|
|
|Short|Long|Help|
|
|
| :--- | :--- | :--- |
|
|
|-h|--help|show this help message and exit|
|
|
|-p|--page_name|Substring required to be part of the name of any found pages|
|
|
|-o|--max_offset|Max offset to add to addresses when looking for leak (default: 72)|
|
|
|-d|--max_depth|Maximum depth to follow pointers to (default: 4)|
|
|
|-s|--step|Step to add between pointers so they are considered. For example, if this is 4 it would only consider pointers at an offset divisible by 4 from the starting pointer (default: 1)|
|
|
||--negative_offset|Max negative offset to search before an address when looking for a leak (default: 0)|
|
|
|
|
### Examples
|
|
```text
|
|
pwndbg> leakfind $rsp --page_name=filename --max_offset=0x48 --max_depth=6.
|
|
This would look for any chains of leaks that point to a section in filename
|
|
which begin near $rsp, are never 0x48 bytes further from a known pointer,
|
|
and are a maximum length of 6.
|
|
```
