Iranian country-point out actors have been observed working with a beforehand undocumented command-and-command (C2) framework identified as MuddyC2Go as portion of attacks targeting Israel.
“The framework’s web element is written in the Go programming language,” Deep Intuition security researcher Simon Kenin reported in a complex report printed Wednesday.
The device has been attributed to MuddyWater, an Iranian point out-sponsored hacking crew that is affiliated to the country’s Ministry of Intelligence and Security (MOIS).
The cybersecurity company reported the C2 framework may have been put to use by the danger actor because early 2020, with recent assaults leveraging it in area of PhonyC2, another tailor made C2 system from MuddyWater that arrived to mild in June 2023 and has experienced its source code leaked.
Regular attack sequences observed above the decades have involved sending spear-phishing emails bearing malware-laced archives or bogus hyperlinks that lead to the deployment of respectable distant administration applications.
The installation of the distant administration application paves the way for the delivery of added payloads, including PhonyC2.
MuddyWater’s modus operandi has considering that obtained a facelift, making use of password-secured archives to evade email security options and distributing an executable as an alternative of a distant administration device.
“This executable has an embedded PowerShell script that instantly connects to MuddyWater’s C2, getting rid of the need for handbook execution by the operator,” Kenin defined.
The MuddyC2Go server, in return, sends a PowerShell script, which operates every 10 seconds and waits for further instructions from the operator.
Though the complete extent of MuddyC2Go’s capabilities are unknown, it truly is suspected to be a framework that is responsible for producing PowerShell payloads in purchase to carry out submit-exploitation pursuits.
“We recommend disabling PowerShell if it is not needed,” Kenin reported. “If it is enabled, we propose near checking of PowerShell activity.”
