Dropper (malware)

A dropper[1][2] is a Trojan horse that has been designed to install malware (such as viruses and backdoors) onto a computer.

[3] Trojan horses operate by masquerading as legitimate programs, requiring user interaction to execute.

For instance, a user might download an application via a text message link, which leads to the device being infected with malware.

[5][6] It facilitates unauthorized financial transactions by exploiting the Automatic Transfer Service (ATS), allowing attackers to siphon funds from mobile banking applications.

This type of malware typically enters devices through sideloading, bypassing official app stores.
