Confucius Hackers: A Sophisticated Threat Actor Exploits Pakistan with New WooperStealer and Anondoor Malware. Stay informed about emerging threats and prioritize your organization's cybersecurity posture to reduce the risk of falling victim to sophisticated attacks.
Confucius Hackers, a notorious group, targeted government agencies, military organizations, and critical industries in Pakistan using spear-phishing and malicious documents since at least 2013. The group's latest campaign uses WooperStealer malware to steal sensitive data from compromised hosts, employing DLL side-loading techniques. Confucius Hackers also employed Anondoor malware, which exfiltrates device information and executes commands, takes screenshots, enumerates files and directories, and dumps passwords from Google Chrome. The group's adaptability is evident in its use of obfuscation techniques to evade detection and its ability to pivot between techniques, infrastructure, and malware families. Organizations must prioritize their cybersecurity posture, invest in necessary tools and technologies, and stay up-to-date on security patches and updates to detect and respond to emerging threats like Confucius Hackers.
Confucius, a notorious hacking group believed to have been active since 2013, has recently targeted government agencies, military organizations, defense contractors, and critical industries in Pakistan using spear-phishing and malicious documents as initial access vectors. This latest campaign marks an evolution of the group's tradecraft and its technical agility.
According to Fortinet FortiGuard Labs researcher Cara Lin, "Over the past decade, Confucius has repeatedly targeted government agencies, military organizations, defense contractors, and critical industries -- especially in Pakistan – using spear-phishing and malicious documents as initial access vectors." This sophistication highlights the threat actor's ability to adapt and evolve its tactics.
The attack chain documented by Fortinet targeted users in Pakistan sometime in December 2024, tricking recipients into opening a .PPSX file, which then triggered the delivery of WooperStealer using DLL side-loading techniques. A subsequent attack wave observed in March 2025 has been found to employ Windows shortcut (.LNK) files to unleash the malicious WooperStealer DLL, again launched using DLL side-loading, to steal sensitive data from compromised hosts.
Another .LNK file spotted in August 2025 also leveraged similar tactics to sideload a rogue DLL, only this time the DLL paves the way for Anondoor, a Python implant that's designed to exfiltrate device information to an external server and await further tasks to execute commands, take screenshots, enumerate files and directories, and dump passwords from Google Chrome.
The group has demonstrated strong adaptability, layering obfuscation techniques to evade detection and tailoring its toolset to align with shifting intelligence-gathering priorities. "Its recent campaigns not only illustrate Confucius' persistence but also its ability to pivot rapidly between techniques, infrastructure, and malware families to maintain operational effectiveness," Fortinet said.
This behavior highlights the importance of staying vigilant and up-to-date on security patches and updates, as well as implementing robust cybersecurity measures to protect against such threats. It is essential for organizations to prioritize their cybersecurity posture and invest in the necessary tools and technologies to detect and respond to emerging threats.
In addition, K7 Security Labs detailed an infection sequence associated with the Patchwork group that commences with a malicious macro designed to download a .LNK file containing PowerShell code responsible for downloading additional payloads and leveraging DLL side-loading to launch the primary malware while simultaneously displaying a decoy PDF document.
The final payload establishes contact with the threat actor's command-and-control (C2) server, gathers system information, and retrieves an encoded instruction that's subsequently decrypted for execution using cmd.exe. It is equipped to take screenshots, upload files from the machine, and download files from a remote URL and save them locally in a temporary directory.
"The malware waits for a configurable period and retries sending the data up to 20 times, tracking failures to ensure persistent and stealthy data exfiltration without alerting the user or security systems," K7 Security Labs said. This behavior emphasizes the importance of implementing robust security measures and regularly updating software and operating systems to prevent such malicious activities.
In light of this latest campaign, it is crucial for organizations to stay informed about emerging threats and to prioritize their cybersecurity posture. By investing in the necessary tools and technologies, as well as staying up-to-date on security patches and updates, organizations can significantly reduce the risk of falling victim to sophisticated threats like Confucius Hackers.
Summary:
Confucius Hackers have targeted Pakistan with a new phishing campaign that has exploited vulnerabilities using WooperStealer and Anondoor malware. The group has demonstrated strong adaptability and layering obfuscation techniques to evade detection, highlighting the importance of prioritizing cybersecurity measures and staying up-to-date on security patches and updates.
