What is Coyote banking trojan

Coyote is a multi-stage banking Trojan that leverages the Squirrel installer for distribution, a method not commonly associated with malware delivery. It is named “Coyote” due to its predatory nature, akin to coyotes being natural predators of squirrels, which is a playful nod to its use of the Squirrel installer. The malware is notable for its sophisticated infection chain, utilizing NodeJS and a relatively new multi-platform programming language called Nim as a loader to complete its infection process. The Coyote banking Trojan is a sophisticated malware targeting over 60 banking institutions, primarily in Brazil. It employs advanced evasion tactics to steal sensitive financial information from victims. This article provides an in-depth look at what Coyote is, how it infects computers, and how to remove it, with a focus on the Windows operating system, as the Trojan specifically targets Windows desktop applications for its distribution and execution.

How Coyote banking trojan infected your system

Coyote’s infection process is complex and involves several stages:

Distribution: Coyote uses the Squirrel installer, an open-source tool for installing and updating Windows desktop applications. This choice of installer allows Coyote to hide its initial stage loader by masquerading as a legitimate update packager.
Execution: Upon execution, Coyote runs a NodeJS application that executes obfuscated JavaScript code. This code’s end goal is to launch a genuine piece of software necessary for carrying out the further infection stage through DLL side-loading.
Loader Stage: The Trojan employs a loader written in Nim, a modern, cross-platform programming language. This loader unpacks and launches Coyote’s executable, a .NET application, completing the infection process.
Persistence and Evasion: Coyote achieves persistence by abusing Windows logon scripts and employs advanced evasion tactics, including string obfuscation with AES encryption and using SSL channels with mutual authentication for communication with its command-and-control (C2) server.
Malicious Activities: Once installed, Coyote monitors all open applications on the victim’s system, waiting for specific banking applications or websites to be accessed. It can execute a wide range of commands, including taking screenshots, logging keystrokes, displaying fake overlays, and more, to steal sensitive financial information
