Application Description

Let’s cite the description of this application below:

The Yandex.Taxi app is a quick, easy, and safe way to order a taxi. No calls, no waiting on hold — just one tap, and your order is sent to the available driver closest to you so they can reach you as quickly as possible.

  • Place an order without calling — just press the button in the app.
  • View the name, phone number and license plate number of the driver who’s picked your order.
  • Pay by card or cash.
  • Track the location of your car on the map.
  • Order a child-friendly vehicle with children’s seats (in Moscow) or bumper seats (in other cities).
  • Add special requests, such as space for a bicycle or snowboard, a pet-friendly vehicle, or a printed receipt.
  • Use the “Black list” feature to avoid unsatisfactory service providers.
  • Rate your journey to give your feedback on the service.

Choose one of several service levels: “Economy,” “Comfort,” “Business,” and for bigger groups, “Minivan.” Get to any of Moscow’s airports — Sheremetyevo, Domodedovo, or Vnukovo — with a fixed-price trip. To see fares for different cities, visit taxi.yandex.com.

Protection levels.

Locally stored data (Data-at-Rest, DAR).

Locally stored data groups include Location ‘n’ Maps Information, Credentials Information.
The average DAR value is 3.50 points (7.00 points of system protection and 0.00 points of own protection). It equals to a typical value (3.5 points, where’s 7 points of system protection and 0 points of own protection).

Items with average value 3.50 points (7 points of system protection, 0 points of own protection) means data protection levels have following definitions. Frankly talking, extra data found that shouldn’t be accessed where system protection level means – root/jailbreak is required but not possible without wiping device data, and own protection level means – stored as is.

– GEO Data (‘Location ‘n’ Maps Information’ Group) – Any GEO info stored as plain text referred to the places or tracked activity. This data item related to mentioned group meant to be any geodata from trackers, social networks, GPS, etc.,

– Address Data (‘Location ‘n’ Maps Information’ Group) – Home, work or another type of owner address stored by apps. This data item related to mentioned group meant to be any geodata from trackers, social networks, GPS, etc.,

– Tracked Data ‘n’ Favorites (‘Location ‘n’ Maps Information’ Group) – Any favorites data or tracked data marked as desirable by users and for users (Means, user is on FB messenger, Viber, bank client or favourite hotel, room type, flight route, airline). This data item related to mentioned group meant to be any geodata from trackers, social networks, GPS, etc.,

– Credentials (IDs) (‘Credentials Information’ Group) – Only account IDs like app or 3rd party user IDs including emails, phone number, usernames, etc. (depends on apps). This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.

Keep in mind if you’re using some Android devices such Samsung, LG or another device with an unlocked or non-locked loader that allow rooting your device without user action, the system level equals 6 points instead of 7. It means your data can be stolen without involving your actions.

Transferred data (Data-in-Transit, DIT).

Transferred data groups include Credentials Information, Analytics ‘n’ Ads Information, Location ‘n’ Maps Information, Payment ‘n’ Transaction Information, Account Information, Booking ‘n’ Purchases Information, Travel Information.
The average DIT value is 5.21 points (6.00 points of system protection and 4.43 points of own protection). It is higher than a typical value (4 points, where’s 4 points of system protection and 4 points of own protection).

Items’ GROUP #1 with average value 5.00 points (6 points of system protection, 4 points of own protection) means data protection levels have following definitions. Frankly talking, data is not available all the time or partially accessed where system protection level means – MITM prevented or fake certificate importing prevented, but plaintext non-protected traffic is intercepted, and own protection level means – bypassed by fake/stolen root certificates.

– Credentials (IDs) (‘Credentials Information’ Group) – Only account IDs like app or 3rd party user IDs including emails, phone number, usernames, etc. (depends on apps). This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.,

Items’ GROUP #2 with average value 5.50 points (6 points of system protection, 5 points of own protection) means data protection levels have following definitions. Frankly talking, data is not available all the time or partially accessed where system protection level means – MITM prevented or fake certificate importing prevented, but plaintext non-protected traffic is intercepted, and own protection level means – server-side limitations (SSL validation/pinning, limited access to outdated records) and client-side limitations (pinning with user-decision behavior, additionally ecnrypted/hashed data item, or own cert storage).

– Credentials (Passwords) (‘Credentials Information’ Group) – Well-known passwords or PINs you’re using to get access to your account (usually it is worse than tokens because it gives full access to your account). This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.,

Items’ GROUP #3 with average value 6.00 points (6 points of system protection, 6 points of own protection) means data protection levels have following definitions. Frankly talking, protection and privacy issues are still possible but might involve interaction with an app code where system protection level means – MITM prevented or fake certificate importing prevented, but plaintext non-protected traffic is intercepted, and own protection level means – SSL pinning (can be patched).

– Credentials (Activation IDs) (‘Credentials Information’ Group) – Two-factor activation code received in messages. This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.

Keep in mind if you’re using out-of-date Android < 7.0, the system level equals 4 points instead of 6. It means your data can be stolen with a crafted preinstalled certificate on the device or if someone makes you install a certificate. Also, if you’re using out-of-date Android < 5.0, the system level equals 2 points instead of 4. It means your data can be stolen without involving your actions.
