Technical Analysis

WhiskerSpy encompasses a diverse array of backdoor commands. It empowers assailants to engage with the compromised system, manipulate files, and initiate code execution. These encompass executing remote shells, facilitating file downloads or uploads, erasing files, generating file listings, capturing screenshots, loading and running executables, and implanting shellcode into active processes.

WhiskerSpy allows cybercriminals to wield arbitrary commands on the compromised system, granting them unrestricted access to its resources. This malware variant also enables the downloading of sensitive files from the compromised system, as well as the uploading of malevolent files onto it, potentially introducing additional malware strains.

Moreover, malicious actors can exploit WhiskerSpy to purge files from the compromised system, potentially erasing their digital traces or disrupting its functionality. Additionally, the malware supports the enumeration of files residing on the compromised system. It aids in identifying potential targets for extraction or manipulation. The Backdoor can also capture screenshots of the compromised system, providing visual insights.

Ultimately, WhiskerSpy is a conduit for executing supplementary code on the compromised system. As a result, it facilitates the potential installation of extra malware or backdoors. Furthermore, it can inject code into active processes, potentially enabling threat actors to execute added commands or access sensitive data with potential ramifications.

Spreading Methods

The infiltration process of WhiskerSpy has been established with certainty. This malware is propagated through a compromised website. The attacker injecting a malevolent script into the website’s code. This script orchestrates the presentation of a notification to visitors, urging them to initiate the download of a codec installer, ostensibly to address a video codec error encountered while attempting to view content on the site.

The codec installer, fashioned as an MSI executable, harbors a series of PowerShell commands. These commands are executed upon installation, culminating in deploying the WhiskerSpy backdoor. Furthermore, the cybercriminals employ a persistence tactic that exploits the native messaging host inherent to Google Chrome. Through this avenue, they introduce a noxious extension termed “Google Chrome Helper.” The foremost role of this extension is to ensure the payload’s execution each time the browser is launched, thereby solidifying the malware’s foothold.
