MuddyWater
Threat Type: APT
Delivery and Exfiltration:
Description: MuddyWater (also known as MERCURY) is an APT which has primarily been used to attack Middle Eastern nations. However, attacks have also been observed against surrounding nations and further abroad. This includes targets in India and the U.S.A.
MuddyWater attacks are characterized by the use of both custom and well-known hacking tools as well as built-in operating system tools for its hands-on-keyboard attack. Despite broad scrutiny and reports on MuddyWater attacks, the activity continues with only incremental changes to the tools and techniques.
MuddyWater Spotlight: In July, researchers observed MuddyWater using Log4j exploits with vulnerable SysAid Server instances as its initial access vector. SysAid provides IT management tools and might have been an attractive target for its presence in the targeted country.
Once initial access is achieved, the threat actor establishes persistence using several methods that include:
- Dropping a web shell that provides effective and continued access to the compromised device
- Adding a user and elevating their privileges to local administrator
- Adding leveraged tools in the startup folders and ASEP registry keys, ensuring their persistence upon device reboot
- Stealing credentials
Threat actors used different methods to communicate with their command-and-control (C2) server, including:
- Built-in operating system tools like PowerShell
- A tunneling tool called vpnui.exe, which is a unique version of the open-source tool Ligolo
- Remote monitoring and management software called eHorus
Target Geolocations: Israel, India, Pakistan, Turkey, Kazakhstan, Armenia, Syria, Bahrain, South Africa, Sudan, U.S.A.

Manjusaka
Threat Type: RAT
Delivery and Exfiltration:
Description: Manjusaka is a newly discovered attack framework. It includes a RAT with the C2 being an ELF binary written in GoLang. The implants are written in the Rust program language and consist of a variety of capabilities that can be used to control the infected endpoint, including executing arbitrary commands. Cisco Talos discovered EXE and ELF versions of the implant.
Functionality includes (but is not limited to):
- Collecting browser credentials
- Getting file information
- Taking Screenshots
- Obtaining comprehensive system information
- Activating the file management module to carry out file-related activities
Manjusaka Spotlight: The researchers at Cisco Talos recently discovered a new attack framework being used in the wild. The framework – which goes by the name “Manjusaka” – is currently being advertised as a Cobalt Strike imitation and has the potential to become a prevalent threat in the near future.
Implants for this new malware family are written in the Rust language for Windows and Linux. Threat actors can find a freely available and fully functional version of the command and control (C2) written in GoLang with a user interface in Simplified Chinese. This makes it easy to create new implants with custom configurations, increasing the chance of wider adoption.
The observed campaign consisted of a distribution of a maldoc to targets, leading to the deployment of Cobalt Strike beacons on the infected systems. The infection chain involves the use of a maldoc masquerading as a report and advisory on the COVID-19 pandemic in Golmud City, one of the largest cities in the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province – specifically citing a case of COVID-19 and the subsequent contact tracing of individuals.

SocGholish
Threat Type: Drive-By
Description: SocGholish is a drive-by malware framework which has an end goal of achieving persistence, performing recon and establishing a C&C channel for follow-up malware. SocGholish infection spreads via compromised websites injected with a malicious JavaScript implant. This implant is responsible for tricking victims into loading and installing fake browser updates. Final malware ranges from RATs to ransomware.
SocGholish Spotlight: Drive-by campaigns have been part of the arsenal of malicious actors, ranging from initial access brokers to ransomware cybercriminal gangs. One such malware framework is SocGholish, which has been in use since at least 2017.
Recent activity of the group behind SocGholish draws a direct link with ransomware groups associated with WastedLocker, PhoenixLocker and Macaw. SocGholish framework is under constant development, which results in multiple types of injects as well as the frequent detection of newly infected or re-infected websites.
It also appears that the threat actors behind SocGholish use multiple TDS services which can maintain control over infected websites for a prolonged time, thus complicating the work of defenders. This malware also uses, amongst other tricks, a domain shadowing technique which used to be widely adopted by exploit kits like AnglerEK. The evolution of such campaigns calls for a layered security approach for the networks.
