### Using similar endpoints
If you are attacking the `/api/v3/sign-up` endpoint try to perform bruteforce to `/Sing-up`, `/SignUp`, `/singup`...
Also try appending to the original endpoint bytes like `%00, %0d%0a, %0d, %0a, %09, %0C, %20`
2022-08-31 22:35:39 +00:00
### Blank chars in code/params
2021-07-26 10:54:04 +00:00
2022-08-31 22:35:39 +00:00
Try adding some blank byte like `%00, %0d%0a, %0d, %0a, %09, %0C, %20` to the code and/or params. For example `code=1234%0a` or if you are requesting a code for an email and you only have 5 tries, use the 5 tries for `example@email.com`, then for `example@email.com%0a`, then for `example@email.com%0a%0a`, and continue...

2022-08-31 22:35:39 +00:00
### Changing IP origin using headers
2021-07-26 10:54:04 +00:00
```bash
X-Originating-IP: 127.0.0.1
X-Forwarded-For: 127.0.0.1
X-Remote-IP: 127.0.0.1
X-Remote-Addr: 127.0.0.1
2020-08-25 08:42:39 +00:00
X-Client-IP: 127.0.0.1
X-Host: 127.0.0.1
X-Forwared-Host: 127.0.0.1
#or use double X-Forwared-For header
X-Forwarded-For:
X-Forwarded-For: 127.0.0.1
```
If they are limiting to 10 tries per IP, every 10 tries change the IP inside the header.
2022-08-31 22:35:39 +00:00
### Change other headers
Try changing the user-agent, the cookies... anything that could be able to identify you.
2022-08-31 22:35:39 +00:00
### Adding extra params to the path
2021-07-26 10:54:04 +00:00
If the limit in in the path `/resetpwd`, try BFing that path, and once the rate limit is reached try `/resetpwd?someparam=1`
2022-08-31 22:35:39 +00:00
### Login in your account before each attempt
2021-11-28 11:01:58 +00:00
Maybe if you **login into your account before each attempt** (or each set of X tries), the rate limit is restarted. If you are attacking a login functionality, you can do this in burp using a Pitchfork attack in **setting your credentials every X tries** (and marking follow redirects).
