So my friends called me up the other night (I didn't recognize one of their phone numbers, so I had no idea who it was) and used a voice synthesizer to make some rather humorous statements questioning my sexuality.

It was pretty funny.

Today, I whipped up a short python script that uses libgmail to send each of them a text message on their cell phones, sending once every 30 seconds, for 200 iterations. I thought it was pretty cool.


So my question is, what are your coolest counterhacks/counterpranks that you've ever pulled on someone? I'm sure there are some good ones out there.

Let's see:

1) You can have immense fun with a smoke machine rigged to the start button of a PC.

2) A camera flash has an interesting effect on somebody who's been carefully wound up about an impending nuclear war for the previous two weeks.

3) The classic "Screenshot the desktop, make it the desktop pic and hide all the icons and dash" trick is harder to do nowadays, but still fun [Smile]

Umm... gee, you've become an amateur spammer. Congratulations. I wonder how many of your friends have plans that charge for incoming SMS messages.

It's great, I would put it on my blog, except of one thing: It's not free [Frown] It's much like the lollerblogger but much more better.
My favourite prank is the Systernals BSOD Screensaver, wow it freaked me out the first time I saw it.

In typical no-one-bothers-to-read tradition of Internet users, everyone has missed the counterprank part, and for that matter, the manly part. But since no-one else is offering what was asked, I guess I am not obliged to either.

On April 1st last year, I decided to have a bit of fun with a hot Malaysian temp at work. When she went to have her tea break (it's England, after all) I switched her PC's keyboard layout from English to French. These two layouts are very similar, but the odd keys are swapped -- Q and A, and W and Z I think also? So she'd come back, resume typing and stqrt finding mysterious mistqkes in her typing.

Qfter q while, I'd heqrd nothing from her, qnd cqlled by her desk to enauire whether everything was OK. It was.

See ... in Windows, unlike Mac OS, some programs, e.g. Microsoft Access, latch on to your current keyboard layout and refuse to obey changes to it. Switch to French and you have to restart the program to have it notice. How they screwed that one up I have no idea. Not that I could have done anything about it, because it could take 10-15 minutes to actually load the company database MDE file (I think my record was an hour and a half of waiting at the point where I gave up and went home).

The joke was, as always, on me.

nerdwithnofriends____________________The best pranks are done to other pranksters, a coworker had just changed his NC program on a big mill. It is always scary after a change, I start up with my hand on the E-STOP button. Any way he changed his program and I snuck up behind the machine and waited for the coolant pump to start (last operation before actual machining) counted to five and started banging the back of the machine with a brass hammer, from my point I could see his feet was he ever dancing around, then he realized what was happoning and started yelling my name (why me).

Usually just wait until a couple of minutes after the normal Windoze startup sound [Smile]

Assuming you have a login on the box, use regedit to edit the users registry to change their home page in IE... Then they think you have their user/password.

Change the host file on their computer to:
point microsoft.com to apple and apple.com to microsoft... Note, microsoft update may not do anything if they have an up date version of XP. Change one their favorite sites to some place awful, depending on their ideas of awful that could be something as clean as furniture porn or as disgusting as Tub Girl.

Spoof their e-mail address and send a "I'm a little girl" e-mail to your other friends.

If you work with them, have high enough computer access and won't catch hell from anyone else -- add another computer (or Virtual machine) to the network with the same name on the Active Domain (windows) or else just spoof their mac address... Disconect and rename the computer everynow and again so their trouble is intermitted.

Old spice... phone, mouse, keyboard, arms of the chair ... you get the idea.

If you work with tem and are on a network at work, and netsend is allowed (windows) or wall/write are avalible (*nix) then schedule a repeating task to message them... With Unix, this could be a great opertunity to use the fortue and the -o flag... Unless you are worried about being sued for sexual harrasment.

Steal computer chair... from either or both work or home ...

Messing with hosts like that doesn't always work. I once took two irritating ad sites that use pop-ups (Tribal Fusion and Drive Cleaner) and used hosts to point each one at the other, such that they'd each get useless log entries.

The joke is always on me. Tribal Fusion used the Host line to realise I was doing this, and presumably fetched the real content for me and forwarded it to me. The wrong IP made absolutely no difference my end at all and I still got intrusive Drive Cleaner pop-ups that didn't want to get stuffed. Drive Cleaner just came up with a dumb error page.

The snag is that when you make a Web request, you have a virtual hosting provision in the form of the Host header line. If the Host line doesn't match the site whose IP to which you are connecting, your results will be unpredictable. The server might declare a virtual host mismatch or build a proxy bridge for you.

The host file should take precedence, and unless the DNS is cached, hosts redirect _SHOULD_ always work.

That said,there are some gottchas... I've read that Microsoft changed the way window's host handles microsofts domain, preventing malware from changing the where Windows gets updates from.

I've run into a timeout error when I put circular entries in (like me apple->microsoft microsoft->apple example), but I am unsure if that was just the OS (which was an OSX box) or if that happens on all systems.

Per the host field in the header, it _shouldn't_ matter, and hasn't for me (on Linux). That doesn't mean that such oddness doesn't occur on other systems. Maby I'll play with my host file and try to replicate your exprience.

Huh? No. It works like this. I put a wrong IP 1.2.3.4 into hosts, for site foo.com, e.g.

1.2.3.4 foo.com

Now, I try to connect to foo.com and ask for /bar.baz, e.g.

gethostbyname => 1.2.3.4
Connect -> 1.2.3.4
GET /bar.baz HTTP/1.0
Host: foo.com
User-Agent: evil/1.0
Accept: ...
etc.

When the computer at 1.2.3.4 sees "Host: foo.com" it realises that you're looking in the wrong place, because 1.2.3.4 is not foo.com

Tribal Fusion would act as a proxy to the real site (the one in the Host line) so you'd still get the site you asked for, regardless of the IP. A site that uses virtual hosting (i.e. most sites) will simply return an error: unknown virtual host. Sites that run their own, dedicated server *and* IP and don't use virtual hosting, may give you their own site, maybe not -- Apple and Microsoft should fall into this category.

It all depends on how the site is set up.

I've never seen it act like a proxy. Then again, my main use is to block sites that annoy me by asigning them to localhost, and the result is a 404. Suppose I was just luckly picking on servers not set up to care about the host field.

You're in luck. It works perfectly for the two examples you suggested. You can swap Microsoft's and Apple's sites over. I've not tried to see or think about how subdomains would be affected however.
