A wave of sophisticated cyber-espionage campaigns has swept across South and East Asia, linking a web of state-backed hackers, evolving malware arsenals, and intelligence ambitions that stretch from New Delhi to Hanoi. As regional powers quietly escalate their digital offensives, the new frontier of espionage is no longer fought with soldiers — but with stealth servers and RATs hidden behind fake government domains.
The Elephant Awakens
A new report has illuminated the growing capabilities of Mysterious Elephant — a highly sophisticated Advanced Persistent Threat (APT) group operating across Asia. Once reliant on borrowed tools, the group now deploys its own suite of custom malware, signaling its rise into the region’s upper tier of cyber adversaries.
Kaspersky analysts describe the collective as “a significant threat to government entities and foreign affairs sectors in the Asia-Pacific region.” Its operations overlap with other Indian-interest clusters like Origami Elephant, Confucius, and SideWinder — all known for precision-targeted intrusions against foreign ministries and strategic institutions.
In early 2025, Mysterious Elephant (also tracked as APT-K-47) launched an extensive campaign leveraging exploit kits, phishing lures, and malicious documents aimed at ministries in Pakistan, Afghanistan, Bangladesh, Nepal, India, and Sri Lanka. The attacks were powered by a PowerShell-based payload chain that dropped BabShell (a reverse shell), MemLoader HidenDesk, and MemLoader Edge — each built to deliver RATs (remote access trojans) capable of data theft and system persistence.

The Tribe Returns
Running parallel to the Elephant’s ascent is the resurgence of Transparent Tribe — a Pakistan-nexus APT (APT36) with a decade-long record of cyber espionage. Recent campaigns observed by French cybersecurity firm Sekoia in August and September 2025 reveal spear-phishing attacks against Indian government entities, primarily targeting users of BOSS Linux — the government’s indigenous operating system.
The malware of choice: DeskRAT, a Golang-based backdoor capable of executing commands, collecting files, and exfiltrating data through WebSocket-based command-and-control (C2) servers. The phishing emails often contain ZIP files masquerading as official PDFs, including one titled “CDS_Directive_Armed_Forces.pdf”, hosted on legitimate cloud services such as Google Drive.
Both DeskRAT and its successor, StealthServer, have evolved through multiple Windows and Linux variants. Researchers found that one version even connects to a server named “modgovindia[.]com”, mimicking a government domain. Others transmit data to modgovindia[.]space:4000 — indicating persistent attempts to exploit India’s defense and administrative ecosystems.
The Stealth Server Ecosystem
The Transparent Tribe’s toolset is no longer static. Reports from QiAnXin XLab trace the emergence of StealthServer, a Golang backdoor that demonstrates a clear evolution toward cross-platform infiltration.
Three Windows versions — V1, V2, and V3 — have been identified, each introducing advanced anti-debugging, persistence, and communication features. V1 relied on scheduled PowerShell tasks and TCP-based communication, while V3 employed WebSockets, mirroring the functionalities of DeskRAT.
Two additional Linux variants extend this ecosystem further: one capable of executing bash commands and file uploads; another featuring a new “welcome” instruction, enabling deeper remote control. Analysts warn that this modularity shows the group’s intent to sustain multi-year surveillance campaigns across both civilian and defense infrastructures.
A Region of Mirrors
These revelations arrive amid a surge of South and East Asian cyber operations — from Vietnam’s OceanLotus (APT-Q31), to SideWinder’s Operation SouthNet, to Bitter APT’s phishing offensives exploiting CVE-2025-8088 in China and Pakistan.
Each group, while pursuing distinct geopolitical goals, shares technical DNA: multi-platform implants, decoy PDFs, and social-engineering lures tailored for diplomats and military users.
Analysts describe the ecosystem as a “region of mirrors” — where adversaries borrow tactics, mimic rival state infrastructures, and disguise national fingerprints behind shared open-source tools. The result is a cyber landscape in which attribution has become a geopolitical act in itself.
“The group’s operations are frequent and characterized by a wide variety of tools, numerous variants, and a high delivery cadence,” said QiAnXin XLab, noting the rising complexity of South Asian APT clusters. As South and Southeast Asia continue to digitize governance and defense systems, the quiet war unfolding in encrypted backdoors may prove as consequential as any battle waged on land or sea
