I had serious quarrel with someone on the web that he threatened that he could find out my IP address.
I also foolishly clicked on his link provided. I think my IP address has been leaked because I clicked
on the link

What is the most precise possible information he could get from me by knowing my IP address as he said
or by clicking on the link he provided?

Who your provider is, maybe.
Your general location, maybe. Location as in...the City of X.

But, you violated the Prime Directive. "Don't click on stupid stuff"
 
I would be FAR more concerned about the possibility of a script (etc.) in that link you clicked.

Do you have really good AV solution in place already?
Personally would suggest a full scan and a manual check through your running processes to be sure you recognize everything.

As above. Additionally (most) IP are using dynamic IP, so in theory you may or may not BE at the same IP for long.

But you DID violate the Prime Directive.

And I agree with the above regarding scripts that have have been behind that clicky.

could he steal my data on computer? I did google search ,it said yes,
what should I install to avoid such thing in the future? thanks
 
just knowing your address does not make you vulnerable. that's public knowledge and anyone that you connect to can see it. for instance i know the white house address is 1600 Pennsylvania ave. that does not mean i can now simply walk in and take what i want :)

your pc is the same way. your address is public knowledge but the security is what protects your house.

do like has been suggested and look close for anything new on your pc.

Now...if there were some malicious scripting behind that clicky link, then maybe.

i clicked on the link and then in another less than probably 3 seconds, I was alert,
and then killed the browsers immediately (I was using mobile phone), am I fine??

now or next time, should I also restart my mobile device to be safer?

what I am worried is that I was on my home WiFi and my IP is quite static (I often check it and it is usually the same over a few months)

Is it ok to live with only the default AV and firewall provided by Windows 10?
Do I need to purchase a third-party AV and firewall solution e..g by Kaspersky?

By the way, do I need to install any AV or firewall on an Android mobile phone??



I connected to the site with the browser apps in my mobile phone (under the home wifi environment which should have the same IP with my desktop PC). Is my PC safer than my mobile phone? I have now disabled the WiFi and cellular data on my mobile phone to avoid any data being sent out. What should I do to see if there is any malicious script on my mobile phone?? Is my PC safe? Thanks. I am worried

OK... I think I am fine now after scanning for virus with Windows default Anti virus now

but how can I scan for "malicious script" or other possible malware on my Android phone??

I cannot find any suspicious Apps and I have tested with Play Protect. Any more I'll need to do????
 
if you connected by your phone, then your pc is safe. there is no way for anything to jump from your phone to the pc.

you don't really need any AV on your phone unless you regularly do stupid stuff with it. but most malware for phones comes through apps you get from the store or other sources. there are very few things written to exploit the phone through the browser itself, most get in through apps you install on purpose.

you should be good to go if your pc passed the scans. the built in win 10 stuff is fine though some of the paid 3rd party programs are better.. but again not really needed unless you regularly do stupid stuff with your pc such as downloading pirated material and other VERY dangerous activities.

HI and Thanks for your advice. I don't normally do stupid thing with either my PC or my mobile phone.

The only stupid thing I did was that I clicked on the suspicious link through the mobile Chrome browser but I then killed the apps immediately within a few seconds. However, I think my IP address could already be recorded because it was still a visit (even if it last only a few seconds)

Since the mobile was connected to the WiFi offered by my desktop PC so they have the same IP address and that's why I connect the issue to the PC

The last question do I still need to install a 3rd party AV apps for mobile e.g. Panda Security, and do a full scan of it?
 
not really needed for the phone. if you did not install anything you are likely safe. you can install something if you wish to be super safe and run the scan it offers. but it's not really needed to keep it on there.

just as a side note, the ip address you show is your punlic address given to you by your isp. your router in the house hands out private addresses usually that look like 192.168.1.* or something similar. but those are only internal to your network. every single device that connects from your home shows the same public ip address. there is no way to stop that since like mailing a letter, it can't be done if the post office does not know the address to send it to. your public ip is just that public info!!

Hi. I know about 192.168.1.* , but the address shown to the public isn't this one.

I have a personal website (written by my close friend) that it would record every
visit for me including the IP address of the visitor. I have tried to visit my site through
my mobile device, the IP address recorded by my website isn't 192.168... something.
and when I google "my ip address". The ip address isn't 192.168 too.... it is probably
my real public ip address (because I can find out my approximated location with that IP )
 
Your public IP address is like your house number. Public knowledge. Every site you go to has to know this, so they can send data back to you.

Your internal IP addresses 192.168.x.x are like a number on the door of each room in your house or apt.

Once that data from the server gets to your router....the router knows which room (PC) asked for it, and sends it to that room.

If data just shows up at the house address (Public IP address), then the router throws it away. "No one here asked for that. Go away"

I have now checked to block all the connections, including allowed apps, under the setting of Windows Defender Firewall. Is it safer?
 
What I have done now
  1. Full virus scan by Windows Defender
  2. Firewall turned on (Window's Firewall)
  3. Windows Update (Security update? maybe)
  4. Router's MAC address updated, but it only changes the last few digits of my IP address
Any more recommended?
 
pretty much all you can do other than disconnecting 100%. the best firewall rule is "deny all" and then slowly add back what specifically you need open to run what you want to run on your pc.

that's what windows firewall can do. block everything and then add back only port numbers you need. stops many of the attack vectors since those services can't be reached if the ports are closed.

Hi.

check “Deny all" right? Would you mind showing me the screenshot of "Deny all"? Because I am using a non-English Windows interface. (I'm not English speaker)

Thanks
 
i don't use windows firewall so not sure how it configures. you'll have to google that and see how they go about doing it. it is basically blocking all traffic except what you specifically allow.

a long time ago i used zone alarm firewall and it had a learning mode which was awesome. it blocked everything as default and then promoted you everytime a connection tried to be made. then you allowed it, blocked it or some other rule. over time it knew what you wanted to avoid and what is allowed and did not bother you again. no idea who still does it this way, but it was a very user friendly way to configure a firewall rather than having to write rules over and over.
 
If you were using the phone . and you clicked on the link inside the phone ,then it is possible that he controls your phone now .

Hacking phones is more serious than PC .

Factory reset it ASAP . AFTER FACTORY RESET , whatsup , Duo , EVERTHING , change ALL PASSWORDS . change every password on every APPS. he has them all.

Dont use old passwords ... for phone or email or anything.

Goto your Email and check forwarding options , he could set it to copy your emails to him from within Gmail.

When you Factory reset , Go into boot menu and wipe out everything , cache , ALL.

This is really serious . and NO anti Virus will help you if you already clicked on the link.

sorry , but if he is a hacker and his link was program , your phone is compromised already .

and a hacked phone will send the hacker everything he wants once it is connected to the internet. EVERYHTING. even your Dynamic IP address , and photoes and contacts and social conversations , he could spy on you and turn the camera ON and the mic without you noticing. even record all your phone calls and send them to his server. EVERYHTHING.

If I do not want to factory reset, what can I do otherwise??

by the way, as I said before, I clicked on the link
but it was an accident, and then I was alert immediately and killed the browser immediately (in less than 2 seconds I believe), I am not sure if I was already connected to the link, but "History" from my mobile browser doesn't show the link.

Was I connected? or not yet connected?

If the history does not show the link then the program deleted its traces .

Actually this is a bad sign. VERY BAD SIGN.

FACTORY RESET IT
