New findings released very last week showcase the overlapping resource code and techniques concerning the operators of Shamoon and Kwampirs, indicating that they “are the exact same group or really shut collaborators.”
“Study evidence shows identification of co-evolution in between each Shamoon and Kwampirs malware family members in the course of the regarded timeline,” Pablo Rincón Crespo of Cylera Labs explained.
“If Kwampirs is primarily based on the initial Shamoon, and Shamoon 2 and 3 marketing campaign code is based on Kwampirs, […] then the authors of Kwampirs would be perhaps the exact as the authors of Shamoon, or should have a incredibly potent romance, as has been observed around the course of many years,” Rincón Crespo added.
Shamoon, also recognised as DistTrack, functions as an facts-thieving malware that also incorporates a destructive ingredient that makes it possible for it to overwrite the Grasp Boot History (MBR) with arbitrary data so as to render the infected device inoperable.
The malware, made by the eponymous hacking crew also tracked as Magic Hound, Timberworm, COBALT GIPSY, was 1st documented by Broadcom-owned Symantec in August 2012. At least two current versions of Shamoon have considering the fact that emerged, Shamoon 2 in 2016 and Shamoon 3 in 2018.
In July 2021, the U.S. govt attributed Shamoon as the handiwork of Iranian condition-sponsored actors, linking it to cyber offensives focusing on industrial manage units.
On the other hand, attack activity involving the Kwampirs backdoor has been connected to a danger team recognised as Orangeworm, with Symantec disclosing an intrusion marketing campaign aimed at entities in the healthcare sector in the U.S., Europe, and Asia.

“Initially discovered in January 2015, Orangeworm has also performed qualified assaults versus companies in related industries as part of a greater supply-chain attack in order to get to their intended victims,” Symantec claimed in an analysis in April 2018.
Cylera Labs’ uncovering of the relationship stems from malware artifacts and previously unnoticed factors, one of which is said to be an middleman “stepping stone” model. It truly is a Shamoon dropper but sans the wiper function, even though simultaneously reusing the very same loader code as Kwampirs.
What is actually much more, code-amount similarities have been uncovered concerning Kwampirs and subsequent variations of Shamoon. This includes the features to retrieve process metadata, fetch MAC deal with, and the victim’s keyboard format info as effectively as the use of the exact InternetOpenW Windows API to craft HTTP requests to the command-and-handle (C2) server.

Also set to use is a prevalent template technique to create the reporter module that properties capabilities to upload host data and obtain more payloads to execute from their C2 servers, a aspect that was missing in the 1st edition of Shamoon.
In connecting the disparate dots, the investigation has led to the assessment that Kwampirs is likely based on Shamoon 1 and that Shamoon 2 inherited some of its code from Kwampirs, implying that the operators of both of those the malware are distinctive sub-groups of a greater umbrella teams or that it truly is the function of a single actor.
This sort of a declare isn’t really with no precedence. Just final 7 days, Cisco Talos comprehensive the TTPs of yet another Iranian actor referred to as MuddyWater, noting that the country-point out actor is a “conglomerate” of many teams functioning independently alternatively than a one danger actor group.
“These conclusions, if in fact appropriate, would recast Kwampirs as a large-scale, multi-12 months attack on worldwide health care provide chains executed by a overseas point out actor,” the researchers concluded.
“The information gathered and techniques accessed in these campaigns have a wide variety of probable use, such as theft of intellectual house, collecting of professional medical records of targets like dissidents or armed forces leaders, or reconnaissance to help in the organizing of long run harmful attacks.”
