Ongoing Campaigns

Fake cryptocurrency apps on Google Play attempt to scam users

  • Reddit users discovered an app on Google Pay called ‘Trezor Mobile Wallet’, impersonating the popular hardware cryptocurrency wallet Trezor.
  • ESET researchers analysed the fake app and found that it can’t cause harm to Trezor users due to Trezor’s use of multiple security layers, however, it is able to phish for Trezor users’ credentials. They also found that the app is connected to a fake cryptocurrency wallet app called ‘Coin Wallet – Bitcoin, Ripple, Ethereum, Tether’ that is used to scam victims out of money.
  • Both the fake Trezor app and the ‘Coin Wallet’ app were created based on an app template sold online. The researchers suspect that the emergence of these apps is related to the continuously rising prices of Bitcoin in the last few months. Both apps have since been taken down from Google Play.

Audio card skimmers preferred over flash skimmers

  • Researchers at Advanced Intelligence observed that audio skimmers are growing in popularity with criminals, due to their ease of use, moderate price and high resilience.

  • The growing popularity of audio skimmers coincides with a drop-in market share for flash skimmers which are cheaper but also less reliable.
