I'm also seeing scans to port 57 TCP, which has history dating to Oct 02 and Nov 02 and is a signature of a tool called FX-Scanner (analysis). Apparently port 57 is used as a host discovery mechanism. Here are three examples.
First, recon for port 1433 TCP:
12 Jun 03 18:22:17 tcp 161.53.40.97.4464 -> my_IP.57 TIM
12 Jun 03 18:22:17 icmp 161.53.40.97 <-> my_IP ECO
12 Jun 03 18:23:04 tcp 161.53.40.97.1217 -> my_IP.1433 TIM
12 Jun 03 18:25:08 tcp 161.53.42.46.2036 -> my_IP.57 TIM
12 Jun 03 18:25:08 icmp 161.53.42.46 <-> my_IP.55 ECO
12 Jun 03 18:25:55 tcp 161.53.42.46.3590 -> my_IP.1433 TIM
Next, recon for ports 80 and 21 TCP:
18 Jun 03 15:02:53 tcp 67.116.81.237.3836 -> my_IP.80 TIM
18 Jun 03 15:03:14 tcp 67.116.81.237.4067 -> my_IP.57 TIM
18 Jun 03 15:02:53 icmp 67.116.81.237 <-> my_IP ECO
18 Jun 03 15:03:35 tcp 67.116.81.237.4325 -> my_IP.21 TIM
Third, recon for ports 1433 and 445 TCP:
19 Jun 03 11:35:14 tcp 4.40.163.36.1951 -> my_IP.57 TIM
19 Jun 03 11:35:38 tcp 4.40.163.36.1725 -> my_IP.1433 TIM
19 Jun 03 11:35:13 icmp 4.40.163.36 <-> my_IP ECO
19 Jun 03 11:37:50 tcp 4.40.163.36.2221 -> my_IP.445 TIM
I'm also seeing recon for 3410 TCP. This has only picked up in the last few days. It appears to be associated with the Backdoor.OptixPro.13:
