A Chinese cyber-espionage actor probable related with the “Operation Comfortable Cell” campaign has been focusing on Middle East telecom suppliers since the beginning of 2023.
The new series of attacks are aspect of what SentinelOne researchers described as “Operation Tainted Adore,” a cyber-espionage marketing campaign exhibiting “a effectively-taken care of, versioned credential theft capability” and a new dropper system.
“The first attack section entails infiltrating internet-facing Microsoft Trade servers to deploy web shells used for command execution,” wrote SentinelOne senior danger researcher Aleksandar Milenkoski in an advisory released earlier right now. “Once a foothold is recognized, the attackers perform a wide range of reconnaissance, credential theft, lateral movement and knowledge exfiltration pursuits.”
Milenkoski highlighted that the deployment of custom made credential theft malware is the most important novelty of the new campaign, which depends on malware incorporating modifications to the code of the Mimikatz article-exploitation instrument.

A individual sample of the malware (dubbed mim221 by SentinelOne) also showcased upgraded anti-detection characteristics.
“The use of unique-function modules that put into action a assortment of sophisticated tactics demonstrates the risk actors’ dedication to advancing its toolset toward highest stealth,” Milenkoski spelled out.
The security researcher also clarified that while backlinks to Operation Soft Cell are apparent, the staff could not right hyperlink the campaign to a specific risk actor.
“That marketing campaign has been publicly associated with Gallium, and feasible connections to APT41 have been instructed by the use of a popular code signing certification and tooling that shares code similarities. APT41 is also acknowledged to goal telecommunication suppliers.”
Both way, Milenkoski explained the threat actors behind Operation Tainted Love would possible go on upgrading their malware and focusing on companies in the Middle East.
“These risk actors will just about absolutely go on discovering and upgrading their resources with new approaches for evading detection, together with integrating and modifying publicly offered code,” he wrote. “SentinelLabs proceeds to keep track of espionage activities and hopes that defenders will leverage the results offered in this write-up to bolster their defenses.”
