The North Korea-linked ScarCruft group has been attributed to a previously undocumented backdoor called Dolphin that the threat actor has used against targets located in its southern counterpart.
“The backdoor […] has a wide range of spying capabilities, including monitoring drives and portable devices and exfiltrating files of interest, keylogging and taking screenshots, and stealing credentials from browsers,” ESET researcher Filip Jurčacko said in a new report published today.
Dolphin is said to be selectively deployed, with the malware using cloud services like Google Drive for data exfiltration as well as command-and-control.
The Slovak cybersecurity company said it found the implant deployed as a final-stage payload as part of a watering hole attack in early 2021 directed against a South Korean digital newspaper.
