I chat a lot in MIRC and someone told me yesterday that he runs a program that ''captures'' your personal data. Your name hour phone number etc. Is it possiple just using my IP address or any otner information from my MIRC connection? I have a university connection and he asked me what is the name of the responsible for the internet connections in my university...I think that he was just jocking, but I am a bit anxious! Can he find my name? And I he can do it, why did he ask me this name? Isn't he capable of finding my name by his onw means? Thank you in advance for your response!

Hi escape_23,

Unless he has installed a keylogger or something like that on your computer, the answer is simple:
No, he can't do that. He's just talking way beond his knowledge :)

But that's what you allready figured out yourself:
>>And I he can do it, why did he ask me this name? Isn't he capable of finding my name by his onw means?<<
He told you he was able to find out, and now he isn't able to find it out???

Greetings,

LucF

there's not an absolute yes/no answer for this.  he's not going to be able to automate this process with any form of 100% certainty, but using an IP obtained from irc as a gateway for further manual exploration, could eventually yield exactly such info.  barring any form of remotely installed malware, computers loaded with a network capable OS generally provide the necessary functionality to take advantage of an unsuspecting user remotely.  at times this is due to misconfiguration, other times from service/system/application flaw.  another possibility would be through infrastructure tampering.  ie. dns poisoning, dhcp packet injection, route manipulations, etc.  i would be willing to bet that most of these are safeguarded well in a university network, but it wouldn't be the first time.

There have been exploits in mIRC for sometime now, and depending on the version you run, you may or may not be vulnerable. Here are a few:

http://www.mondoirc.net/forum/topic.asp?TOPIC_ID=1789

many applications suffer from exploits and security holes very similar to these. Typically people who know what they are doing, will not tell you, unless they are script kiddie newb's who think they are cool because they DL'd a tool and know how to use it. So what I say is ignore this fellow, get a firewall and AV if running M$, update all your software regularally.

I agree with  richrumble, that you cannot make any assumption that you are secure, especially if using "chat a lot in MIRC "

Fortunately you are not at home and do have a few protections while at school.

>  Is it possiple just using my IP address or any otner information from my MIRC connection?

No. Exploits like that need a little more help, and we won't post any 'how-to' concerning that.

>  he asked me what is the name of the responsible for the internet connections in my university.

The answer to that question is very trivial, indicating your 'chat friend' is not very knowledgeable if he has to ask.

> Question Title: IP security

IP is networking, which is never really perferctly secure. Keep that in mind, behave well, and do not offer personal information easily

IT department efforts to secure university networks tend to run headlong into tenured faculty who believe that any attempt to filter or monitor network traffic infringes upon their "academic freedom".  Even if the university has staff who understand what should be done (most do), DO NOT assume that they are actually permitted to do it!
