A few notes... |
| 19 |
|
| 20 |
1) It's UDP (User Datagram Protocol). |
| 21 |
|
| 22 |
2) UDP is a connectionless protocol, i.e. no 3-way handshake like TCP. |
| 23 |
That means that the sending software can put any garbage they want |
| 24 |
in the source-port and source IP address. *DO NOT* complain to the |
| 25 |
ISP responsible for 215.146.157.191. UDP forgery is trivial. |
| 26 |
|
| 27 |
3) This garbage is spewed out by zombie bots to port 1026 to pop up |
| 28 |
messages on your screen if you'r running the Windows Messnger Service. |
| 29 |
It'll probably show up if you have Samba configured right/wrong (Ain't |
| 30 |
Windows emulation wonderful?). Everybody gets hit with it, just like |
| 31 |
port 135 and 1433 and 1434 scans. Here's an hour's worth from my |
| 32 |
router's log. The router is set to reject unsolicited traffic... |
