In the wake of the craze, malware variants of Pokémon GO & other related apps have appeared on the Google Play store.
Malware apps documented to-date:
● Pokémon GO Ultimate
● Guide & Cheats for Pokémon GO
● Install Pokémongo
Promptly removed from the Google Play store, they may still appear on third-party app stores.
Impacts of the malware in question include:
● locking device screen
● rename itself to evade counter measures
● remove itself from the device app menu to evade counter measures
● run in the background & click on ads to generate income for its creator
● display messages that claim that the device is infected with malware (actually true) which advise the user to buy further apps & services to remove malware
● install a backdoor app called DroidJack (aka SandroRAT) which grants an attacker full access to the device
What you can do to protect yourself:
● keep all software up-to-date, including Android itself – as they become available for your device
● avoid using third-party app stores – apart from Amazon
● avoid apps from unknown developers
