Port 1092 is registered for OBRPD (Open Business Reporting Protocol), but if you find something listening here, it's probably not that.
What Range This Port Belongs To
Port 1092 sits in the registered ports range (1024-49151). These ports are registered with IANA for specific services, but the registration doesn't guarantee anyone actually uses them. Applications can request a port number, get it assigned, and then... nothing. The protocol never gains traction. The software never ships. The port just sits there, registered and empty.
That's port 1092.
The Protocol That Wasn't
OBRPD stands for Open Business Reporting Protocol. It's registered. It has a name. But try to find documentation, implementations, or anyone actually using it. You won't. The protocol exists in IANA's database and nowhere else.1
This happens more than you'd think. Someone has an idea for a protocol, registers a port number, and then the project dies. The port remains registered—a tombstone for software that never lived.
What Actually Used This Port
The Lovgate worm did.
In the early 2000s, Lovgate (also called W32.Lovgate) was a mass-mailing worm with backdoor capabilities. It would infect Windows computers, spread through email and network shares, and then open a backdoor on port 1092.2
The backdoor was password-protected. A hacker who knew the password could connect to port 1092 and get a command shell on the infected machine. Full control. The worm would even email the hacker to let them know a new machine was ready.3
Port 1092 required authentication. Port 20168 (another Lovgate backdoor) didn't. Different doors, different levels of caution.
Lovgate is long dead. Modern antivirus caught up. Patches closed the vulnerabilities it exploited. But for a brief window, port 1092's primary use was letting attackers in.
Why Unassigned Ports Matter
Most ports are unassigned. Out of 65,535 possible port numbers, only a few thousand have official assignments. The rest are available for anything.
Unassigned ports matter because they're how new protocols are born. When someone creates new software that needs network communication, they pick a port. Sometimes they register it. Sometimes they don't. Sometimes the software succeeds and the port becomes well-known. Sometimes it fails and the port goes back to being empty.
The registered range (1024-49151) is where this experimentation happens. OBRPD tried. It didn't work. The port remains, waiting for something else.
How to Check What's Listening
On Linux or macOS:
On Windows:
If you see something listening on port 1092, investigate. It's probably not OBRPD. It might be legitimate software using an available port. It might be malware. The port number doesn't tell you which—you have to look at what's actually running.
The Honest Truth
Port 1092 is registered for a protocol nobody uses and was briefly famous as a malware backdoor. That's the whole story.
Most technical writing won't tell you this. They'll say "port 1092 is reserved for OBRPD" and leave it at that, as if the reservation means something. But reservations don't matter if nothing shows up.
The Internet is full of ports like this. Names in a database. Registrations from optimistic developers whose protocols never shipped. Empty addresses waiting for traffic that will never arrive.
Port 1092 is one of them.
