New APT Cyber espionage group Orangeworm targeting healthcare sectors and other medical related industries to deploy the powerful Kwampirs backdoor to compromise the medical devices such as X-Ray & MRI Scan Machines.
Kwampirs backdoor initially discovered in 2016 that can able to open a potential backdoor in compromised computers to steal the sensitive information and also download malicious files.
The orangeworm APT cyber group mainly targeting healthcare sector in the U.S., Europe, Asia and they are active since 2015.
Apart From Healthcare industries, Orangeworm APT also targeting the related industries such as healthcare providers, pharmaceuticals, IT solution providers for healthcare and equipment manufacturers that serve the healthcare industry.
Orangeworm high amount of attack registered against Healthcare industries and other related industries also infected followed by Healthcare.
According to Symantec, We believe that these industries have also been targeted as part of a larger supply-chain attack in order for Orangeworm to get access to their intended victims related to healthcare. Orangeworm’s secondary targets include Manufacturing, Information Technology, Agriculture, and Logistics.
Orangeworm Attack Against X-Ray and MRI Machines
Kwampirs backdoor discovered within the software that used to control the medical equipment such as X-Ray and MRI machines and also Orangeworm was recognized to have an interest in machines used to assist patients.
The biggest amount of victims have been identified in the U.S with 17 percent of the infection and India, Saudi Arabia, Philippines etc countries are severely affected next to the U.S.
Initial infection leads to compromise the network and deploy the Kwampirs backdoor that takes a remote control of the victim’s machine.
During the infection, it using randomly generated string to decrypt the payload to evade the signature-based detection.
Also, it performs various tasks to maintin its persistence and this backdoor collect information about the compromised computer including some basic network adapter information, system version information, and language settings.
This APT malware also investigates the strength of the victims whether the system used by a skilled person or if the victim is a high-value target.
Cybercriminals using the various command in the victim’s network to gathering the huge volume of sensitive information from network adapter information, available network shares, mapped drives, and files present on the compromised computer.
Kwampirs uses sophisticated techniques to propagate itself once inside a victim’s network by copying itself over network shares.
It established connections into a large amount of command & control servers but not all the C2 servers are active but it keeps communicate with it until it makes a successful connection.
Researchers believe that this hacking group might be work of an individual or a small group of individuals.
