A new malware campaign targeting Android users in Finland is using social engineering to trick individuals into installing a fake McAfee antivirus app, leading to financial losses for some victims. The scam involves receiving a text message urging the recipient to dial a specific number and then installing the malicious app by sideloading an APK file. Finnish authorities have warned about the deceptive text messages, and victims are advised to contact their bank and reset their Android device to factory settings if they have installed the fake app.
