message: my windows version of netcat is upsetting ad-aware and apparently some virus scanners. I'm adding a sentence or two saying this seems overcautious, any other perspectives / info on security risks would be good

Maybe people should remove the part where it says nc can be used as a backdoor.
Heck, anything can be used as a backdoor, including purposely compiled binaries or SSH or inetd+telnet or other combos.
Symantec says this about it:
"Upon further analysis and investigation we have determined that the following file(s) meet the necessary criteria to be detected by our products and, as such, the detection(s) cannot be revoked:
    File name: nc.exe
    MD5: ...
    SHA256: ...
    Detection: NetCat"
...as if it were a nasty virus. Or maybe their criteria are that anything not used by a receptionist is automatically a *gasp* "hack tool".
Last time I heard of those dreaded "hackers", they also used keyboards, mice, monitors, even cat5 cables sometimes.
To by-pass this piece of super-smart detection without removing the Symantech piece of artwork, recompile nc from scratch.
Also remember to never use this high quality of antiviruses on production systems when they can suddenly decide to delete important files randomly.

thread_title:  netcat flagged up by virus / spyware scanners 

message: It seems that such command like
nc -L #targetip -p #port-number -v -t -d -e cmd.exe
is a Windows only command, because the original necat does not have the option -L. See the Netcat Mannual Page
:No, it just needs to be compiled with specific flags enabled to activate the -L flag. For security reasons, most precompiled distributions aren't compiled with these flags, so the -L flag is usually not available, and you need to recompile it yourself if you want that. The windows compiled versions, for whatever reasons, are precompiled with those flags. -82.156.210.192 (talk) 15:41, 4 August 2008 (UTC)

thread_title:  Netcat is USEFUL, remember 

message: I wouldnt say nc can be used for hacking, more debugging.. If you refer to the malicious action that is trying to break into a system, that'd be called cracking.

thread_title:  Evil netcat? 

message: According to the man page for nc, 
  -l      Used to specify that nc should listen for an incoming connection rather than initiate a connec-
             tion to a remote host.  It is an error to use this option in conjunction with the -p, -s, or -z
             options.  Additionally, any timeouts specified with the -w option are ignored.
but the example on the page shows $nc -l -p 3333.

replies: text: Hm, indeed and I was about to change this, but: netcat-traditional seems to need "-l -p 3333", it won't listen on a local 3333 port without the -p. The more flexible netcat-openbsd does not accept -p in combination with -l and the manpage contains the comment you quoted above. However, I'm not too eager providing examples for all netcat versions out there, I think the few examples are more than enough for an encyclopedia :) 78.47.219.222 (talk) 19:57, 9 August 2009 (UTC)

message: The infobox in the article says the latest version is 1.10 March 20, 1996, while the linked homepage says : 0.7.1 released on 11 Jan 2004. Someone should fix it up.

thread_title:  Version weirdness 

message: I'd like to see a table of the netcat variants.  I think it should include all the the programs that are trying to be descendants (in spirit) of *Hobbits*'s netcat, whereas cousins should not be in this table.  I have started one here, but I did not put it in the article because it is not complete.
