+ 6 Votes TechRepublic members do not aid system/password cracking wizard57m-cnet Moderator March 17, 2013 at 12:51am PST TR members do not assist in password recovery or removal. Do not respond to this thread. We, the members of TechRepublic - A Resource for IT Professionals, will not assist anyone in the recovery/removal of lost passwords. You may have a legitimate reason to recover/remove a password. However, we cannot verify your motives and will therefore not assist anyone in what may be an attempt at gaining unauthorized access to a computer system. Due to the open nature of this forum, any assistance given to help circumvent security measures, even for legitimate purposes, would be available for unscrupulous individuals to use for illegitimate purposes. This is a risk that we, the members of TechRepublic, will not take. Please do not ask questions of this nature on TechRepublic. If you have a legitimate need to circumvent a password scheme, please contact the vendor for the software / hardware and request their assistance. E.g. Windows XP password recovery/removal issues should be taken up with Microsoft's technical support, Phoenix BIOS password recovery/removal issues should be taken up with Phoenix Technologies, hard drive password recovery/removal should be taken up with the manufacturer of the hard drive, etc...

The only thing I know is who STARTED the harassment. He'd been doing creepy, scary things for years all on his own (as far as I know) before anyone else signed on to join him, and God only knows how something like that can happen. One would think it would be a serious challenge finding just one sicko kindred spirit to participate in something like this, let alone a bunch? Seems like it would be, but constantly telling myself that this couldn't be happening didn't make it so, because it was happening. (And pedophiles manage to find one another, so ...? Some people are gross; I'll leave it there.) And Slayer, no, the guy never got caught. I believe he's currently working as a "consultant" for a major internet service provider. As to why I've written about this now: I learned the term "rootkit" from a kindly tech guy who I'd spoken with about the problem, and I did share what I'd been told about them (as well as the details of my library experiences) with the head librarian, but I don't know that any action was taken. Had I been able to print out that professional journal article on the subject that was written expressly for librarians perhaps it might have helped my case. I suspect that the librarian's take on me at the time was that on the one hand I seemed sane, but on the other hand I was describing something that seemed SUPER unlikely, and I'm guessing she wasn't hearing about this problem from anyone else. (I'd gone to the library, by the way, because my computer at home had been similarly compromised.) Had she been better informed she would have helped me, I think.This happened in 2006, yet in 2013 there still seem to be very few lay people who've even ever heard of a root kit, or other stuff of that ilk, and I think it's essential for everyone to understand that things like this have happened and do happen. Certainly all administrators of computer networks need to be aware of this stuff. I shudder to think of the things that are surely happening to other good people out there, and the way they'll likely be treated if they dare to speak about it or seek help. To be targeted for harassment is really hard, but to be dismissed out of hand as someone who's psychotic (and the idea there, though not admitted, is often that the mentally ill person is by definition not worth actually helping) ----that is devastating ---especially when some people apply this label so contemptuously. Let's face it: If I were deluded because of a brain disease it would not be my fault. Furthermore, the awful reality is that there are some bad people who relish victimizing those who are vulnerable, who will be questioned and dismissed: those with mental illness, people with developmental disabilities, people with poor support systems and lack of income, etc. This stuff happens. In my opinion it would be far better to take all complaints seriously (i.e., actually investigate them) than to not do that and be an unwitting accomplice to an evil scumbag who preys on the vulnerable. Real innocent people are being hurt out in the digital Wild West, and they are being abandoned by others who might help them. At least a couple of people here at TR have called this thread a silly discussion about something that doesn't really merit any attention, but they're mistaken. + 2 Votes hard to know without seeing the desktop computer in question. Slayer_ March 17, 2013 at 1:07pm PST it is possible that there was remote control software on that computer in the library. Something like vnc could have been used. + 1 Votes Lock the thread. demotricus March 17, 2013 at 6:31pm PST If you`re the Moderator then just lock the thread.... + 0 Votes It might be an admin RSmiedy March 17, 2013 at 11:28pm PST Dear birchswinger, I do believe that this has happened to you and I might be able to shed light on this problem. The person doing this to you most likely is using an administrator's account. I have established this therory because a friend of mine was looking at adult rated sites at the library (not a good idea) and they locked the computer up tighter than fort knox and exited all of the web browsers. I hope that this has helped with your problem. + 3 Votes Possible gechurch March 18, 2013 at 3:49pm PST Wizard and I will have to agree to disagree. Perhaps you've asked dodgy questions in the past (I haven't looked up your history) but I see nothing in your post asking for help to crack passwords or break system security, and I'm certainly not going to offer advice on anything such so I'm sure I can't be breaking any guidelines in answering your question. This certainly is weird, but not impossible. The messages you are seeing could be sent using "net send" which lets you send a popup message to another computer over the network (provided the security on the computers is weak enough). The screen colours changing could potentially be a dying monitor, and the thing disappearing could be Internet Explorer crashing. If all these things coincidentally happened then it's possible that there is no rootkit/infection involved. That's very unlikely to be the case though - I think you've basically answered your own question mentioning the rootkit. If he managed to infect the library PCs the rootkit would be sitting there waiting for commands. He could potentially do anything he wanted to with the machine. Given the symptoms this seems likely to be what he has done. If it were me I'd report it to the library/technical staff and suggest they run offline virus scans (or dedicated rootkit detection tools) on all the machines. Also be aware that if the machine is infected he could be detecting all the keystrokes you type, so don't use any passwords. + 4 Votes Thanks to some of you re: the scary experience in the library birchswinger Updated - April 22, 2013 at 9:09pm PST Wow. First, thank you to gechurch, Rsmiedy, and Slayer for your rational, respectful responses to my question.( The only reason that I posted a similar questions elsewhere was that I thought I'd failed to post my first question successfully because I hadn't completed the registration process.) And now for the rest of you: As gechurch correctly pointed out, I asked no questions as to how passwords might be circumvented. Wizard57m-cnet's false statement that I "was asking how to break the security at the library's computer system" because I want "TR members to show me how to crack system security" is seriously objectionable coming from someone who is "serving" as a moderator on this site. Given the wording of both of my questions, "wizard", I'm gonna say you're the bull-goose paranoid here, and not I. And for crying out loud, what is your excuse for your infantile rudeness to Rsmiedy? Are you kidding me? You're supposed to be a "moderator"? You and several others certainly have reason to wonder at my strange story. It is incredibly weird, and no doubt about it. It was also extremely frightening to live through, and no amount of telling myself, "This is not happening because this can't be really happening" made it stop happening. You don't know that I'm delusional (I'm not, with witnesses and police reports to back me up) and really have no business casting aspersions on my character, intelligence or sanity ---all of which are well intact. Did it occur to you at all to show a bit of compassion? It really seems like it didn't. (Frankly even if I were suffering from delusions there would have been much more appropriate ways to respond.) I'm about to lose power, so I'll wrap up with another thanks to the nice folks out there. Nobody needs a ****-by-**** tutorial on how this nasty stuff is accomplished, but someone who's been victimized does need someone knowledgeable to go to bat for her when others take it upon themselves to dismiss her as "delusional". + 3 Votes Content Filters Nunob March 19, 2013 at 3:29am PST Content filter's or behavior monitoring applications can be configurred to popup pretty much any verbiage. As an example here I have configured our service to popup various different warning messages for different content. These messages replace whatever content is found to be potentially bad on the site so say that a specific banner advertisment on a website contains a keyword or content I have elected to block it will just be replaced with one of my messages. I notice at times when i am surfing the internet that on some websites some of the adverts will say 1 message and others will say another so i know from the verbiage what rule was violated by that advertisment or the site I was trying to surf. Now I have tried to make the messages descriptive so that others will understand what the warnings are. With that said it may be possible that what you are facing is the content filtering of the library and whoever configured it was less descriptive in their warning messages. It also is possible that you are actually seeing advertisments on the sites that are directed at searches for things that have been searched for like "Am I being hacked" or similar on that system. So you are basically elluding to someone is stalking you, ok if that is the case you need to contact your local authorities and the administrator at the library and inform them that you think this is happening. Until then it is easy for people to let their minds conjure up all sorts of ideas and to be worried about things that are only a perceived danger. For me I find it is best to find out if I have something to stress out about before I let my little hamster loose in the cage to run because I don't like to expend energy on worrying until I need to. If the library computers are being remotely controlled they need to know. If you are being harrassed the police need to know. So I encourage you to first find out if you have anything to worry about and if you do take the steps to protect yourself and others. + 3 Votes Maybe Someone Had Hacked the Library System Warwick05 Updated - March 19, 2013 at 4:08pm PST Hie I am no geek when it comes to computer security but from my experience I think this stalker might have hacked the library system and somehow managed to create a rootkit that monitors you when ever you login in to the system and start disrupting you, if this could help there is a software called RAT , its a remote access tool used to send Trojans and control whatever system that is infected the way you like, I suggest you read about it maybe you will have a n understanding on how it is possible. + 0 Votes I'm going to be evil here but... Slayer_ March 20, 2013 at 12:34am PST Since it was originally posted on TR, it should be ok. If the Library has open wireless. Download firesheep for firefox and use it to monitor the network. Then steal your stalkers login credentials and mess with them for a bit. + 3 Votes I'll think twice in the future... cybergrrl March 20, 2013 at 2:12am PST ...before asking any questions on TR as a result of this thread. I agree the response by wizard57m-cnet is rude and insulting, not only to birchswinger, but to other TR responders as well. I'm glad to hear that's not the norm. It seems the "helpful" responses here have helped explain "how" this could have happened, just as birchswinger asked, without giving any suggestion of hacking, cracking, or password circumvention. There's a difference between asking how a computer can be compromised and how to compromise a computer.
