pwnlib.adb — Android Debug Bridge

Provides utilities for interacting with Android devices via the Android Debug Bridge.

Using Android Devices with Pwntools

Pwntools tries to be as easy as possible to use with Android devices.

If you have only one device attached, everything “just works”.

If you have multiple devices, you have a handful of options to select one, or iterate over the devices.

First and most important is the context.device property, which declares the “currently” selected device in any scope. It can be set manually to a serial number, or to a Device instance.

# Take the first available device
context.device = adb.wait_for_device()

# Set a device by serial number
context.device = 'ZX1G22LH8S'

# Set a device by its product name
for device in adb.devices():
    if device.product == 'shamu':
        break
else:
    error("Could not find any shamus!")

Once a device is selected, you can operate on it with any of the functions in the pwnlib.adb module.

# Get a process listing
print(adb.process(['ps']).recvall())

# Fetch properties
print(adb.properties.ro.build.fingerprint)

# Read and write files
print(adb.read('/proc/version'))
adb.write('/data/local/tmp/foo', 'my data')
class pwnlib.adb.adb.AdbDevice(serial, type, port=None, product='unknown', model='unknown', device='unknown', features=None, **kw)[source]

Encapsulates information about a connected device.

Example

...   FILE *fp = fopen("/proc/self/maps", "r");
...   int n = fread(buf, 1, sizeof(buf), fp);
...   fwrite(buf, 1, n, stdout);
...   return 0;
... }''')
>>> filename = adb.compile(temp)
>>> sent = adb.push(filename, "/data/local/tmp")

b'... /system/bin/linker\n...'
pwnlib.adb.adb.current_device(any=False)[source]

Returns an AdbDevice instance for the currently-selected device (via context.device).

Example

Example

>>> adb.getprop() # doctest: +ELLIPSIS
{...}
pwnlib.adb.adb.install(apk, *arguments)[source]

Install an APK onto the device.

This is a wrapper around ‘pm install’, which backs ‘adb install’.

Parameters:
  • apk (str) – Path to the APK to intall (e.g. 'foo.apk')
  • arguments – Supplementary arguments to ‘pm install’, e.g. '-l', '-g'.

pwnlib.adb.adb.listdir(*a, **kw)[source]

Returns a list containing the entries in the provided directory.

Note

This uses the SYNC LIST functionality, which runs in the adbd SELinux context. If adbd is running in the su domain (‘adb root’), this behaves as expected.

Otherwise, less files may be returned due to restrictive SELinux policies on adbd.

pwnlib.adb.adb.logcat(*a, **kw)[source]

Reads the system log file.

By default, causes logcat to exit after reading the file.

Parameters:stream (bool) – If True, the contents are streamed rather than read in a one-shot manner. Default is False.
