NGINX Hijacking Campaign Targeting Asian TLDs: Threat, Tactics, and Implications

Navigating the Web Traffic Hijacking Campaign Targeting NGINX

In the ever-evolving landscape of web security, a new campaign has emerged, targeting NGINX installations with an insidious flair. This operation, primarily aimed at servers managed via Baota (BT), is not just a threat; it's a sophisticated play on web traffic hijacking that could have far-reaching implications for Asian TLDs and beyond.

The Heart of the Attack

At its core, this campaign leverages shell scripts to inject malicious configurations into NGINX. These aren't your average tweaks; they're designed to capture and redirect incoming requests through servers under attacker control. This is a clear attempt to hijack web traffic, potentially leading to data breaches or even more sinister activities.

Where It Hits

The focus of this campaign is both strategic and selective. By targeting Asian TLDs like .in, .id, .pe, and .bd, as well as Chinese hosting infrastructure, the attackers are playing into a pattern that's increasingly becoming recognizable in cybersecurity circles. Additionally, they're eyeing government and educational domains (.edu, .gov), which adds an extra layer of concern given the sensitive nature of these sites.

The Tools at Their Disposal

This operation isn't just about brute force; it involves several carefully crafted scripts designed to streamline the process:

• zx.sh: This orchestrates the execution of subsequent stages in the attack.
• bt.sh: Directs attacks towards Baota Management Panels, overwriting NGINX configurations with malicious intent.
• 4zdh.sh and zdh.sh: These scripts help enumerate common NGINX locations and minimize errors when creating new configurations, ensuring that each step of the hijacking process is as seamless as possible.
• ok.sh: Generates reports on active hijacking rules, providing a glimpse into how widespread this campaign has become.

A Mystery Awaits

While we have the mechanics down, who's behind these attacks remains a mystery. However, there are hints pointing towards exploiting vulnerabilities like CVE-2025-55182, which could explain their initial foothold in systems.

The GreyNoise Revelation

Recent insights from GreyNoise add another layer to our understanding of this campaign. IP addresses 193.142.147[.]209 and 87.121.84[.]24 are hotspots for React2Shell exploitation attempts, suggesting that these actors are actively engaged in the hijacking game.

Conclusion: A Call to Action

This campaign is a stark reminder of the importance of vigilance in web security. As we navigate through this maze of threats, it's crucial to not only patch vulnerabilities but also to stay informed about emerging trends and tactics used by cybercriminals. Let's keep our guard up and continue to push for safer digital practices across the globe.
