The growing prices and popularity of cryptocurrencies don’t just attract masses of potential users, but also inspire cyber-crooks to find new and creative ways to get their sticky fingers on all those virtual coins. Of course, cryptocurrency scams are not exclusive to PCs and have already emerged on the Android platform, using a wide array of disguises.

Fake cryptocurrency exchange apps
Cryptocurrency exchanges are an attractive target for crooks not only due to their popularity with cryptocurrency enthusiasts, but also because many don’t offer a mobile app. Such “unclaimed territory” acts like a magnet for scammers who waste no time coming up with malicious fakes.

Typically, the purpose of such fake apps is to phish for login credentials to the impersonated official exchange. Attackers then use the stolen credentials to take over the compromised accounts. To lure users into giving away their passwords, crooks try to raise as little suspicion as possible – the developer name, app icon and user interface usually mimic those of the legitimate service, and the app may even appear to have a good overall rating thanks to fake reviews.

A recent case of this type of scam are phishing apps impersonating the cryptocurrency exchange Poloniex, discovered on Google Play last year and frequently resurfacing ever since.

Fake cryptocurrency wallet apps
Similar phishing schemes also afflict users of cryptocurrency wallets, only instead of a password, the attackers are directly after the wallets’ private keys and phrases. In practice, this means that the stakes are higher for users of cryptocurrency wallets – a stolen password to a cryptocurrency exchange may be reset with the help of the exchange holding the user’s private key, but in the case of a wallet, it’s the private key that gets compromised, with no one else to save the day.

Lately, we’ve observed this kind of malicious behavior in apps impersonating MyEtherWallet, a popular, open-source, Ethereum wallet. The apps, uploaded to Google Play multiple times over recent months, attempt to steal users’ private keys and/or mnemonic phrases using various bogus login forms. Like the Poloniex exchange, MyEtherWallet doesn’t have an official mobile app, which makes it attractive for imposters.
