West Houston, TX — A recent global campaign believed to originate from China-linked threat group APT41 has brought renewed attention to the vulnerability of government and enterprise IT environments. While the most recent espionage operations have been observed targeting IT infrastructures in Africa, the techniques and tools used in the attack have global relevance—and Impress IT Solutions in West Houston is at the forefront of helping organizations guard against these advanced threats.
🎯 What Happened?
Security researchers revealed a sophisticated intrusion campaign in which APT41 targeted unmonitored internal services, exploited privileged accounts, and used custom malware alongside legitimate tools like Cobalt Strike and Mimikatz. A compromised SharePoint server was repurposed for command-and-control (C2) communications, acting as a covert channel for data exfiltration and command execution.
Some of the attack vectors included:
-
DLL side-loading via trusted applications
-
Execution of trojans via Windows services
-
Malicious use of PowerShell and HTA scripts to establish persistent backdoors
-
Exploitation of legitimate administrative utilities such as Impacket and RawCopy
-
Data theft from browsers, email clients, SSH sessions, and more
