[Rfkill/PyRic issue]: pyric.error: [Errno 19] No device at None

[s7x]

Version: commit 4e1052f

Description

Information

• OS: Archlinux with Blackarch repos
• Kernel: 5.12.10-arch1-1
• Cards used/Chipset: Ralink Technology, Corp. RT5572 Wireless Adapter (Panda Wireless PAU09 N600), 2 identical cards
• Injection/AP mode compatible?: Yes

Hello there!

s7x here, from the Blackarch Linux team. There seems to be an error in the pyric/utils/rfkill.py file in the soft_blocked() function preventing wifiphisher to run properly. I think the problem lies in the rfkill_list() function though. As shown in the screenshot below, when I run the rfkill_list() function, it does not properly indexes the phy#N/wlanN cards/interfaces in the rfks dict.

iw dev showing the phy#N cards/interfaces:

When running rfkill list, I can see that the cards are not blocked (neither hard/soft blocked):

Things tried

• Disabling NetworkManager
• airmon-ng check kill
• Only using 1 card
• rfkill unblock manually

Script Output

> wifiphisher -aI wlan1 -eI wlan2

Don't hesitate to ask if you need more information.

Hi @s7x,

Thanks for reporting this. Development is pretty slow these days. Hopefully, we'll find some time to have a look within the next few months.

Hi @s7x,

First of all, thanks for the detailed report. I'd like to mention PyRIC is a separate library maintained by @wraith-wireless. That being said, I can't replicate your issue on my machine (Ubuntu). When I replicate your experiment with manually pasting the code for rfkill_list into python (bpython to be exact), I get an error that getname is not defined. After defining that function it works fine. Did you declare it "above" your screenshot?

P.S. @sophron I was literally just typing this when you commented...

Hi @JetseVerschuren & @sophron, first of all: thank you for your feedbacks on the issue!

No worries on the delays @sophron I understand. It's to help us keep track on the issues encountered on tools in Blackarch's side too :)

Regarding PyRIC causing trouble, I need to specify that I was using the fork from @sophron in my test. I also tried the @wraith-wireless version but I'm having the same issue when running wifiphisher: (pyric.error: [Errno 19] No device at None).

I did in fact import all the pyric/utils/rfkill.py content in ipython before running the script.

Hello @s7x , @sophron , friendly Noob here. I was having the same issue on Ubuntu 20.04, re-installed the OS multiple times along with the proper Python packages. It was to no avail. I kept getting the same issue you are having. I found it interesting that when i did a fresh install of Ubuntu 18.04 LTS, and installed the Python packages and dependencies along with sudo apt-get install net-tools, it actually worked. I couldn't get the victim machine to connect to my Evil Twin "Couldn't get IP", but after running the following commands (sudo systemctl disable systemd-resolved.service &
sudo systemctl stop system-resolved
), The "Couldn't get IP" issue was resolved and Wifiphisher worked without Errors. Maybe with your extensive knowledge you can investigate what differentiates Ubuntu 18.04 & 20.04, and that could possibly lead the authors to a better diagnostic. Sorry i can't be of much help. P.S after installing and succesfully running an attack with Wifiphisher, i tried to upgrade from 18.04 LTS to 20.04 LTS using terminal and after doing so, wifiphisher gave me multiple Errors along the way and could not find a solution anywhere. Hope my experience can offer you guys some hints, thank you for your hard work. The cards i was using during this Alfa AWUS036NHA and Alfwa AWUS036ACS (5ghz capable).

@sophron @s7x tracked down to pyric/net/wireless/rfkill_h.py line 123:

it says: rfk_rfkill_event = "IBBBB" but should be rfk_rfkill_event = "IBBBBB"

at least in my setting (kali linux - debian rolling testing ?? )

i goes that :
RFKILLEVENTLEN = struct.calcsize(rfk_rfkill_event) ----> is 9 instead of 8

so :

def rfkill_event(idx,rtype,op,hard=0,soft=0):
"""
create a rkfill event structure
:param idx: index of dev rfkill i.e. 0,1
:param rtype: type of rfkill
:param op: op code
:param hard: hard state one of {0=unbloacked|1=blocked}
:param soft: soft state one of {0=unblocked|1=blocked}
:returns: a rfkill event structure
"""
return struct.pack(rfk_rfkill_event,idx,rtype,op,hard,soft)

should return a byte more like --> return struct.pack(rfk_rfkill_event,idx,rtype,op,hard,soft, unknown)

don't know what the byte is for, according to https://github.com/torvalds/linux/blob/master/include/uapi/linux/rfkill.h

is for:

struct rfkill_event_ext {
__u32 idx;
__u8 type;
__u8 op;
__u8 soft;
__u8 hard;

/*
 * older kernels will accept/send only up to this point,
 * and if extended further up to any chunk marked below
 */

__u8  hard_block_reasons;  ## -------> ?????????????????

} attribute((packed));`

__u8 hard_block_reasons; let me know if you know more,

found something : https://patchwork.kernel.org/project/linux-wireless/patch/20201104134641.28816-1-emmanuel.grumbach@intel.com/

I just found out what the problem is, I only keep one wireless card, through ifconfig wlan0 down, and then run sudo wifiphisher and it works!
