What is Hyperlonica Hijacker?

The Hyperlonica extension is deemed as a browser hijacker that forcibly modifies browser configurations to control user ‘s online search. First identified in March 2025, this malware family primarily operates as a search engine manipulator targeting all major browsers including Chrome, Firefox and Edge. Unlike conventional adware, Hyperlonica employs advanced persistence mechanisms through registry implants in Windows systems (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run) , enabling it to survive standard browser resets.

Hyperlonica uses its polymorphic code structure that adapts to different browsers, injection of malicious proxy settings via PAC files, and synchronization of hijacked preferences across devices through compromised browser accounts. The hijacker forcibly replaces Google with its own search portal that routes queries through affiliate-tracked results while inserting sponsored content into organic SERPs.  Hyperlonica  major Infection symptoms include:

1. Irreversible default search engine alterations across all installed browsers
2. 400-500ms latency in page loading due to injected tracking scripts
3. Appearance of unfamiliar extensions like “Hyperlonica ” or “StellarXenonor”
4. Unusual network traffic on ports 8888/TCP and 9999/UDP
5. 30-40% increased RAM consumption from hidden crypto-mining routines
