Computer Hackers?

Question

Is it possible to tell if your computer has been hacked into?

Okay but can you tell me how you can tell please?

Yes, strange ball don't get any ideas now because I WIll be waiting with my lttle virus checkerer

Surely a computer cannot be hacked into if it is closed down and switched off??

Not saying that anyone would wish to hack into mine. Nothing on my computer that would warrant the time and effort it takes to hack into a computer.

No I do not have any reason to believe my computer has been hacked into I was just being curious. Also I have the preventative measures in place. Though you do hear about hackers bypassing these systems.

Answer 1

If someone's done a decent job, they'll cover their tracks. The question now is: what makes you think you, specifically, have been targetted when there are more potential targets out there?

Addendum:

If a computer has been switched off but has already been sufficiently compromised then that exploit will still be available when the computer is switched on again.

Further Addendum:

There could be any number of reasons for an individual to attack your system, however the majority of attacks these days are automated.

Why would a home user be attacked? Probably to install a rootkit or trojan intent on hiding a more subversive tool, like a keylogger (logs every keystroke you make, with the goal of acquiring user accounts and passwords); web proxies for intercepting HTTP requests and redirecting them to false sites (advanced phishing attacks aimed at stealing funds from bank accounts); and the likes of back doors that allow folk and automated processes easy access to your machine - particularly for establishing or expanding botnets that act as platforms for launching likely illegal activity.

Alternatively, if someone wanted to learn the tools of the hacking trade then they've got to start somewhere. And if they can't afford a small network of their own (or never considered virtualization - see link) then our ISPs' public networks are just as good a proving ground as anywhere else.

Answer 2

It all depends. Not all hacks are bad...For instance, I did alittle hack on my computer and changed the WinXP start button to something I think is alittle better lookin than "start". For someone to "hack" your computer, you may never know, or they may erase your whole computer, or they may send you little messages, or they may take control of your computer. What you are asking is vague and difficult to answer. The only way to really tell is to install a sniffer, like WireShark and then capture every packet that goes into and out of your computer, and analyze it for problems. This is alittle too complex for most people. Firewalls can provide you some security, but when it comes down to it, commercially, or publicly available firewalls still have security issues, and hackers WILL find them. So your other option is to write your own firewall. Alittle too advanced for most users also. They can also embed viruses, worms, auto-dialers, trojans (not the condom), and other nasty little crap into it to make your computer do funny things, these are considered being "hacks" too, but no one actually hacked your computer.


So to answer your question, it MAY be possible to tell if you computer has been cracked/hacked, it may not, depends what the cracker/hacker did. You should probably spend some time reading up on security and then go accordingly about your business. Also, if you use a wireless card, the security on that is so poor it's scary. I run a laptop that has a wireless card, and was in a hotel, running a sniffer on my machine, and was able to see very sensitive information, plain as day, and they other people didn't even know it. Read up on it, learn alittle about network security, and then go from there.

To tell if you have been hacked, install a firewall like the free ZoneAlarm from download.com. Set it up to monitor all activity.

Wait a day and then look at the log. If there was activity on the Internet while you were not at home or in the middle of the night, you are being hacked.

Answer 4

Yes, it'll slow down a LOT and 'act' like it's doing a LOT when you're not doing anything on it.

You need to use a good firewall to keep this from happening.

First, clean it up with Anti-virus, Anti-Spyware and other Anti-malware progs. You can get free ones at http://www.download.com/Security-Spyware/2001-2023_4-0.html?tag=dir

I use Avast Antivirus FREE, Spybot Search & Destroy and Lavasoft's AdAware. They have all been quite reliable for me for SEVERAL years now.

Zone Alarm Free is a good free firewall

good luck

Answer 5

its only possible to detect viruses, if someone physically hacked into your computer(through a wireless system etc) its virutally impossible to detect it unless you note changes in your computer or files missing. Most dont leave a trace- so its always best to put a security system/password on your computer/ internet. An antivirus software if its a virus I recommend ad aware se - you should be able to dl it from the net for free....i should know i get tons of viruses but it cleans them all up.

Answer 6

DDoS stands for disbursed Denial of provider. it truly is a pc crime, which includes prompt an finished load of computers to many times and right away make requests to a objective, in an attempt to clog up its factors. that's the undesirable type of hacking, established as black hat. each and every thing else you describe is the solid type of hacking, established as white hat. Perl is a programming language which permits you to jot down courses so the pc will do what you like it to. Compiling is what you want to do to get a software that you've written to be comprehensible by technique of the pc. Flash is fairly a classic software, maximum computers have it. you want it to get admission to youtube and a large kind of different internet sites on the web. An ISP is a web provider service - the employer that you get your internet by. some are faster, more low-cost, extra appropriate, than others. Linux is an option to homestead windows. i exploit it, because I choose the options it delivers. also, distinctly a lot all software for Linux is loose, and criminal. with reference to the DDoS - maximum safe practices experts those days have a heritage of blackhat hacking. although, they have advanced previous it. What you want to do is communicate over along with your son, attempt to comprehend what drives him, and help him to comprehend that what he did became incorrect. although, be careful now to not deter him from doing solid issues on computers. you could sense it acceptable to self-discipline him - i'd advise some thing like a month ban from utilising the pc, and proscribing his get admission to to the pc to three hours an afternoon for the 5 months after.

Answer 7

Yes

Answer 8

yeah, get spyware, and/or anti spyware

except for finding women who like the same things I do, I can think of no reason I'd want to spy on anyone

I figure, why would I care if anyone hacked into my computer?
