3.1 Threats to your assets

As you have already seen, for many the threats are most likely to arrive as emails or attached to emails. Another significant threat comes from apps for mobile devices that are not what they seem. In 2019, Sophos reported apps that hide their icons and use other tricks to prevent the user uninstalling them while aggressively displaying advertising.

Other examples reported include:

  • Many utility apps don’t initially contain malware but include the code to download and install malware from elsewhere. This extra code installed may be designed to collect your banking details, or lock you out of your phone until you pay the criminals.
  • A VPN client that installs a trojan designed to capture banking details.
  • Fleeceware – apps that pretend to offer a free trial for some simple function and ask you to provide banking details first. Even after uninstalling the app, users still get charged a large amount unless they explicitly cancel the trial.
