Artifacts intended for macOS had been very first noticed in July 2023, impersonating installers for genuine program these as CapCut. Other variants of the malware have masqueraded as AnyConnect and security applications.
On installation, JaskaGO operates checks to identify if it is executing in just a virtual equipment (VM) ecosystem, and if so, executes a harmless task like pinging Google or printing a random quantity in a possible effort to fly below the radar.
In other scenarios, JaskaGO proceeds to harvest information and facts from the sufferer program and establishes a link to its C&C for acquiring even further guidelines, such as executing shell instructions, enumerating operating processes, and downloading more payloads.
It really is also capable of modifying the clipboard to facilitate cryptocurrency theft by substituting wallet addresses and siphoning documents and info from web browsers.

It truly is now not recognised how the malware is dispersed and if it entails phishing or malvertising lures. The scale of the campaign remains unclear as however.
“JaskaGO contributes to a increasing development in malware progress leveraging the Go programming language,” Caspi reported.
“Go, also acknowledged as Golang, is recognized for its simplicity, performance, and cross-platform capabilities. Its ease of use has manufactured it an desirable decision for malware authors searching for to build flexible and advanced threats.”
