A threaded implemenation of JARM tool.
To run a scan, provide a list of targets together with port in one file. The following examples are all supported:
massJARM.py -i <targetfile> -t <number of threads, default 4>
The format of the input file should include IP/Domain and Port, separated by colon ":", one per line.
The basic process involves:
- Create a list of probes for a given host and port using different TLS versions.
- Open a connection to the host and port and send the probe.
- Receive the response (up to 1484 bytes). Receiving more or less can change the hash.
- Parse the Server Hello from the received data.
- Calculate the JARM hash.
- Print out JARM in a CSV format
usage: threat-queue.py [-h] [-i INPUT | -t THREADS]
optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
Provide a list of IP addresses or domains to scan, one domain or IP address per line together with a port (e.g. 8.8.4.4:853).
-t THREADS, --threads THREADS
Number of threads to use (default is 4)
| Test | Number of threads | Time Taken | Test Command |
|---|---|---|---|
