Static vs. Runtime Reachability: Insights from Latio’s On the Record Podcast
The Latio podcast explores how static and runtime reachability help teams prioritize exploitable vulnerabilities and streamline AppSec workflows.
slipmatio-user-agents
Advanced tools
A library to identify devices (phones, tablets) and their capabilities by parsing browser user agent strings.
This is an opinionated fork of python-user-agents. The aim is to use modern tooling and keep the package up to date to be useful and safe. PRs welcome!
user_agents
is a Python library that provides an easy way to identify/detect devices like mobile phones, tablets and their capabilities by parsing (browser/HTTP) user agent strings. The goal is to reliably detect whether:
user_agents
relies on the excellent ua-parser to do the actual parsing of the raw user agent string.
slipmatio-user-agents
is hosted on PyPI and can be installed with uv:
uv add slipmatio-user-agents
Alternatively, you can also get the latest source code from Github and install it manually.
Various basic information that can help you identify visitors can be accessed browser
, device
and os
attributes. For example:
from user_agents import parse
# iPhone's user agent string
ua_string = 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'
user_agent = parse(ua_string)
# Accessing user agent's browser attributes
user_agent.browser # returns Browser(family=u'Mobile Safari', version=(5, 1), version_string='5.1')
user_agent.browser.family # returns 'Mobile Safari'
user_agent.browser.version # returns (5, 1)
user_agent.browser.version_string # returns '5.1'
# Accessing user agent's operating system properties
user_agent.os # returns OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')
user_agent.os.family # returns 'iOS'
user_agent.os.version # returns (5, 1)
user_agent.os.version_string # returns '5.1'
# Accessing user agent's device properties
user_agent.device # returns Device(family=u'iPhone', brand=u'Apple', model=u'iPhone')
user_agent.device.family # returns 'iPhone'
user_agent.device.brand # returns 'Apple'
user_agent.device.model # returns 'iPhone'
# Viewing a pretty string version
str(user_agent) # returns "iPhone / iOS 5.1 / Mobile Safari 5.1"
user_agents
also expose a few other more "sophisticated" attributes that are derived from one or more basic attributes defined above. As for now, these attributes should correctly identify popular platforms/devices, pull requests to support smaller ones are always welcome.
Currently these attributes are supported:
is_mobile
: whether user agent is identified as a mobile phone (iPhone, Android phones, Blackberry, Windows Phone devices etc)is_tablet
: whether user agent is identified as a tablet device (iPad, Kindle Fire, Nexus 7 etc)is_pc
: whether user agent is identified to be running a traditional "desktop" OS (Windows, OS X, Linux)is_touch_capable
: whether user agent has touch capabilitiesis_bot
: whether user agent is a search engine crawler/spiderFor example:
from user_agents import parse
# Let's start from an old, non touch Blackberry device
ua_string = 'BlackBerry9700/5.0.0.862 Profile/MIDP-2.1 Configuration/CLDC-1.1 VendorID/331 UNTRUSTED/1.0 3gpp-gba'
