This is all good advice, although it has been my experience that many Android devices are woefully out-of-date when it comes to operating system patches – not because of any failing by the user, but rather that an upgrade path has simply never been made available.A major contributor to this article appears to have a close connection with its subject.

However, a deeper investigation uncovered that Tizi-infected apps stretched back as far as October 2015. Google says that it spotted the Tizi spyware in September, after it was picked up by automatic scans from Google Play’s built-in scanner – Google Play Protect. The natural conclusion is that this is not a widespread attack, but instead an attempt by somebody to launch a focused, targeted attack against carefully-selected targets. Google has identified some 1300 infected devices, with most of the installations based in Kenya. The good news is that most Android users don’t seem to have encountered Tizi. In short, you’re unwittingly carrying a spy around in your pocket. Tizi apps can also record ambient audio and take pictures without displaying the image on the device’s screen. The backdoor contains various capabilities common to commercial spyware, such as recording calls from WhatsApp, Viber, and Skype sending and receiving SMS messages and accessing calendar events, call log, contacts, photos, Wi-Fi encryption keys, and a list of all installed apps. Subsequent command-and-control communications are normally performed over regular HTTPS, though in some specific versions, Tizi uses the MQTT messaging protocol with a custom server. It usually first contacts its command-and-control servers by sending an SMS with the device’s GPS coordinates to a specific number. In addition, the Tizi malware is capable of recording ambient audio and taking photographs without the knowledge of users.Īfter gaining root, Tizi steals sensitive data from popular social media apps like Facebook, Twitter, WhatsApp, Viber, Skype, LinkedIn, and Telegram. Tizi-infected apps, say researchers, have been advertised on social media websites, Google Play and third-party sites.Īside from snooping on communications sent via the likes of WhatsApp, Telegram, Viber, and Skype, Tizi can also send and receive SMS messages, access the user’s call log, calendar, photos, Wi-Fi encryption keys, as well as a list of installed apps. Tizi is known to have been used in attacks against devices in a variety of African countries, with the majority of infections being spotted in Kenya. The malware, known as Tizi, is described as a fully-featured backdoor that can root targeted Android devices and install spyware without the knowledge of the user. Google Play’s security team has shared details of a family of Android malware spotted in the company’s official app store, capable of stealing sensitive data from social media apps and spying on WhatsApp, Viber, and Skype communications.
