Description

When I explode the RDP protocol, if the target system is installed with anti-virus software and the explosion is blocked, Hydra will always be in the scanning state. Specifying - t 1 has no effect. The test scan has a total of 6 passwords, and the scan cannot exit normally. The output above seems that the scan has been completed, but it will still be scanned, I don't know how to solve this problem. image

Research direction
Investigate the Hydra source code, particularly the core loop in hydra.c and the RDP module (hydra rdp.c). Look for how Hydra handles connection timeouts or failures when the target closes the connection unexpectedly. The issue mentions that specifying t 1 does not help, so examine the threading and connection retry logic. Check if there is a signal handler or condition that should stop the scan but isn't triggered. Review the comments on the issue for any additional clues or proposed fixes.
